    All-Weather Sheathing: From Heat Waves to Freezing Temperatures, A Year-Round Performer

    Temperatures are rising year around in the Unites States, with some of the warmest years on record in the past decade. Summer heatwaves are increasing in both frequency and intensity, with the hottest regions sustaining temperatures exceeding 100° F.

    However, the United States offers a diversity of climate zones, and the building materials used on homes and buildings must not only withstand ordinary wear and tear but also perform consistently through every season. The development of “all-weather sheathings” that can handle temperature extremes without compromising structural integrity or energy efficiency are booming in popularity.

    In addition, the 2021 International Energy Conservation Code (IECC) includes changes to improve energy efficiency in a wide variety of structures, and insulated sheathing helps to satisfy these new requirements. And contractors, installers, and homeowners are looking for high-performance, integrated solutions that meet the needs and requirements of any climate zones.

    Maximizing Energy Efficiency: A 4-in-1 Solution

    One way to enhance thermal efficiency across the entire building envelope is by incorporating continuous insulation (CI) in building designs. CI minimizes thermal bridging, a process where heat travels through conductive building materials such as metal or wood studs, leading to energy loss. By reducing or virtually eliminating these thermal bridges, continuous insulation helps to maintain consistent interior temperatures, resulting in a more comfortable indoor environment and less reliance on heating and cooling systems.

    Some products take the savings even further. For example, OX-IS structural insulated sheathing is a 4-in-1 solution that combines structural sheathing, continuous insulation, an air barrier, and a water-resistant barrier in a single product. This comprehensive approach allows builders to streamline the construction process while achieving superior thermal performance. This saves on labor and the amount of separate building materials that construction managers need to purchase. From a performance perspective, the continuous insulation layer within the OX-IS material helps to create a tighter building envelope. This significantly reduces heating and cooling costs, often by an impressive 20% to 40%. The resulting energy savings for owners over the course of a building’s lifecycle are significant.

    In addition to its insulating properties, OX-IS acts as an airtight barrier, reducing air infiltration more effectively than traditional OSB and house wraps. This means less energy is needed to maintain desired interior temperatures, further improving energy efficiency. With these combined benefits, OX-IS insulated sheathing is an ideal choice for builders looking to meet or exceed energy efficiency standards while delivering enhanced comfort and long-term durability for the structure for homeowners.

    Zone Requirements: Addressing the Unique Needs of Every Climate Zone

    Insulation codes, including those set by the IECC, determine minimum standards to help structures maintain consistent indoor temperatures and energy efficiency.

    • Hot-Humid Zones (1-3): From hot, humid areas in southern Texas to hot, dry areas in the Southwest and mixed-humid areas in the Southeast, code requirements for insulation are set in place for buildings to resist humidity, reduce heat gain, and protect thermal efficiency. These climate zones place a heavy focus on vapor barriers within insulation to prevent excessive moisture build up. 
    • Mixed and Cold Zones (4-5): The pacific Northwest, Midwest, and much of the Great Lakes region require higher insulation levels to maintain temperatures during the colder months, which requires managing moisture and heat resistance.
    • Very Cold to Subarctic (6-8): These climate zones cover parts of the northern Rockies and Great plains, northern parts of the U.S., and Alaska. These areas carry the highest insulation demands to aid in protection from the extreme cold, often needing specialized systems to minimize thermal bridging.

    Using continuous insulation systems such as OX-IS helps to meet or exceed IECC requirements across all climate zones for insulation, particularly in the zones with stricter guidelines. IECC insulation requirements are tailored to the specific needs of each climate zone to ensure energy efficiency, moisture management, and thermal comfort. In hot-humid zones, insulation focuses on managing heat gain and preventing moisture intrusion, while mixed and cold zones prioritize retaining heat during colder months and controlling moisture. Very cold to subarctic zones face the most extreme conditions, necessitating high insulation levels and specialized systems to protect buildings from severe cold to minimize energy loss.

    Weathering the Storm: All-Weather Resilience

    In a time when extreme weather conditions are becoming the norm, selecting the right building materials is more critical than ever. All-weather sheathing offers a resilient and high-performance solution that meets the demands of diverse climate zones across the United States. By providing continuous insulation, superior airtightness, and moisture management in a singular product, builders and contractors can achieve IECC standards and create energy-efficient, comfortable spaces year-round. With its ability to reduce heating and cooling costs for the long term, all-weather sheathing proves to be a versatile, year-round performer that’s ready for any environment.

    Creating Healthy Indoor Environments with Continuous Insulation

    A building’s indoor environment can shape the actions, health, and productivity of its occupants. Considering that the average person spends 90% of their time indoors, this puts a high emphasis on ensuring indoor spaces are healthy environments for all occupants. That is why builders and owners are faced with the important task to improve indoor air quality, temperatures, lighting, and acoustics.

    How do you define a “healthy building?” What does having one – or building one – really mean?

    It starts with selecting building materials that prioritize the health and comfort of those inside. With materials such as structural continuous insulation, building owners can guarantee a seamless thermal barrier, reducing heat transfer, minimizing the risk of a sick building, and improving energy efficiency.

    Thermal Efficiency and Weather Barrier

    Continuous insulation minimizes thermal bridging, which occurs when heat is transferred through building materials, such as the studs. However, when installed continuously and properly, continuous insulation contributes to the overall tightness of a building envelope from a thermal perspective. This results in more consistent indoor temperatures, reducing heat loss in the winter and minimizing heat gain in the summer.

    This helps maintain consistent indoor temperatures, reducing the need for excessive reliance on the HVAC system. A stable indoor temperature not only improves comfort but also prevents the growth of mold and mildew, which thrive in environments with fluctuating temperatures that lead to condensation.

    Systems such as OX-IS structural insulated sheathing have benefits beyond just enhancing thermal efficiency. The integrated structural continuous insulation is a 4-in-1 product that includes structural sheathing, continuous insulation, an air barrier, and a water-resistant barrier. The system is designed to boost performance of the building envelope and protect it from water intrusion.

    Ultimately, materials such as OX-IS help meet today’s most stringent energy efficiency codes while simultaneously eliminating the need for additional materials, driving down overall construction project costs.

    Crucial Moisture Control

    Thermal bridging can create cold spots where condensation forms, leading to moisture-related problems. By minimizing or eliminating thermal bridging, continuous insulation significantly reduces the likelihood of condensation and moisture build up within the wall assembly.

    Continuous insulation provides a uniform barrier that reduces temperature differences across the building envelope, which helps to prevent the conditions that cause condensation. OX-IS also eliminates the risks posed by moisture via the material’s built-in air and water barrier. Ultimately, by controlling moisture levels, integrated continuous insulation materials maintain the structural integrity of the building and creates benefits for the indoor environment.

    In addition, structural continuous insulation systems can be seamlessly integrated with other building components, such as flashings and drainage planes. This integration is crucial for promoting proper drainage and ensuring that moisture does not penetrate into the wall cavity. By directing water away from the building envelope and preventing it from entering the interior, these systems play a vital role in maintaining the longevity and performance of the structure.

    The Ideal Indoor Air Quality

    In addition to providing thermal and moisture control, integrated structural continuous insulation materials significantly enhance the airtightness of a building envelope. By creating a barrier against air infiltration, the material minimizes the entry of outdoor pollutants such as dust, pollen, mold spores, and other airborne irritants. This airtight seal improves indoor air quality by reducing the presence of these contaminants and enhances the efficiency of the HVAC system.

    With fewer drafts and less likelihood of uncontrolled air leaks, the HVAC system can maintain consistent indoor temperatures more effectively and with less energy, leading to a healthier indoor environment. By limiting the infiltration of external pollutants, continuous insulation helps to create a cleaner, more comfortable indoor space, reducing the risk of allergies and respiratory issues for occupants.

    Healthier, More Sustainable Spaces

    Designing healthy indoor environments is a necessity for the well-being and comfort of occupants. Integrated structural continuous insulation plays a critical role in achieving this through enhanced thermal efficiency, moisture control, and improved air quality.

    By embracing high-performance materials such as structural insulated sheathing, building owners can meet stringent energy codes, reduce costs, and most importantly, foster healthier, more sustainable indoor spaces that enhance the quality of life for everyone inside.

    HUD Mandates 2021 IECC Compliance: OX’s Affordable Pathway for Builders and Buyers

    2024 has brought additional energy efficiency mandates that are poised to have ripple effects on builders and homeowners nationwide.

    The U.S. Department of Housing and Urban Development (HUD) and the U.S. Department of Agriculture (USDA) have adopted new standards with regard to new home construction. In essence, only homes built to the 2021 International Energy Conservation Code (IECC) will be approved for Federal Housing Administration (FHA) financing for buyers.

    This decision has far-reaching implications in the construction industry and has sparked significant debate within the housing sector. In fact, the National Association of Home Builders (NAHB) has raised concerns about the potential impact on housing affordability in its article “New Nationwide Codes Mandate a Major Blow to Housing Affordability,” particularly for first-time homebuyers. Housing affordability has already become a major challenge in the United States, and some worry these new mandates will only exacerbate the problem.

    With the standards in place, builders and homeowners are searching for high-performance, cost-effective building materials that can help lower construction costs while delivering the energy efficiency to meet the 2021 IECC standards. Many of them are turning to manufacturers such as OX Engineered Products.

    Understanding the Impact of the 2021 IECC

    The 2021 IECC is designed to improve energy efficiency in new homes, thereby reducing overall energy consumption. It has been embraced by jurisdictions across the country. However, meeting these standards does not come without costs. Literally. In fact, NAHB points out that building to this code can add up to $31,000 to the price of a new home. For first-time homebuyers, particularly those relying on HUD or FHA loans, this increased cost can be a purchasing barrier, particularly with rising real estate costs in general.

    However, energy efficiency does not have to be prohibitively expensive. By incorporating advanced, integrated building materials that offer superior performance without excessive costs, builders can meet the 2021 IECC standards while keeping homes at a more modest price point.

    The Integrated, Energy-Efficient Solution

    OX Engineered Products offers an ideal solution to this complex equation.

    The 4-in-1 OX-IS weatherization system is designed to not only streamline construction but save builders on costs while delivering long-term energy efficiency for homeowners. The integrated structural continuous insulation material possesses four layers: structural sheathing, continuous insulation, an air barrier, and a water-resistive barrier. By combining four products into one, builders can help minimize construction costs (lowering the price of the home for buyers) while aiming to meet the latest IECC standards.

    Enhanced Thermal Performance: OX-IS provides continuous insulation, reducing thermal bridging and improving the overall energy efficiency of the building envelope. This can help new homes meet the 2021 IECC standards more readily, especially when combined with other energy-efficient measures such as spray or batt insulation in the wall cavities, a proper HVAC system, and high-performance windows.

    Cost-Effective Solution: While some energy-efficient materials can be costly, OX-IS offers an affordable option that helps builders and homebuyers avoid any steep price increases associated with the new code requirements. By combining multiple products into one, it keeps builders from having to purchase house wrap, insulation, and sheathing products separately. Material prices have risen over the last few years, while OX’s product pricing has remained stable.

    Structural Integrity: In addition to its insulating properties, OX-IS also provides structural sheathing, reducing the need for additional materials and labor. In essence, builders no longer have to worry about purchasing OSB, which leads to substantial savings, particularly when it comes to larger-scale multifamily construction.

    The Rocky Mountain Institute (RMI) advocates for the ruling for the IECC standards. RMI reported that during a 7-day heat wave and power outage in Houston, TX, a house built to the 2021 IECC would stay at safe temperatures and humidity levels for an entire week. The RMI report states, “Bringing Houston’s housing stock up to the newly finalized HUD-USDA standards would prevent about 80 percent of heat wave-related deaths.”

    In addition, for builders, there is a competitive advantage that can be gained. Those who can effectively integrate energy-efficient practices and materials into their projects can market them as more sustainable, appealing to a growing segment of eco-conscious buyers.

    Bridging the Gap

    The NAHB’s concerns about price hikes and overall affordability are valid, underscoring the importance of using innovative materials and construction techniques to mitigate these costs. OX Engineered Products is committed to providing solutions that not only meet the most stringent energy efficiency standards but also keep new homes within reach for first-time homebuyers. This is critical for these buyers to be able to secure FHA-insured mortgages and ultimately buy a home.

    By incorporating OX-IS, builders can create homes that are both energy-efficient and more affordable. This approach helps to comply with the 2021 IECC and supports the government’s goal of increasing the supply of new homes without pricing out the most vulnerable buyers.

    Insulated Sheathing: Improving Thermal Performance in Exterior Walls

    For any construction project in the 21st century, achieving energy-efficiency is a prime directive. Among the arsenal of tools available to builders charged with constructing exterior walls, insulated sheathing stands out as a key component in enhancing overall thermal performance. These integrated materials, such as the innovative solutions offered by OX Engineered Products, play a vital role in optimizing energy efficiency, providing structural strength, and enhancing comfort levels for occupants inside.

    Total Thermal Performance

    Insulated sheathing is designed to enhance the performance of a building’s thermal envelope while adding structural strength. By providing an additional layer of continuous insulation on the outside of the exterior walls, it helps reduce thermal bridging, which occurs when heat is transferred through materials with higher conductivity, such as wood studs or metal framing. This results in more consistent indoor temperatures, reduced heat loss in winter, and minimized heat gain in summer. When installed with the proper seam tapes and used in conjunction with thermally efficient windows and doors, the material can significantly bolster a building’s overall energy efficiency.

    Furthermore, integrated insulated sheathing materials can serve as a moisture barrier as well, protecting the building from water infiltration and condensation. This not only improves the long-term durability of the structure but also enhances indoor air quality by preventing mold and mildew growth.

    In addition to its thermal and moisture benefits, insulated sheathing – when installed continuously and properly – contributes to the overall air tightness of a building envelope. This air sealing effect helps reduce the infiltration of outside air, preventing energy loss associated with unwanted drafts. When combined with other energy-efficient building practices, such as the proper sealing of joints and penetrations, insulated sheathing can play a pivotal role in achieving a high-performance building envelope that meets or exceeds energy code requirements.

    These materials specifically help meet the 2021 International Energy Conservation Codes and can assist builders and owners in achieving significant federal rebates such as the 45L tax credits.

    Integrated Solutions: The OX-IS Advantage

    A prime example of a high-performance integrated material is OX Engineered Products’ OX-IS insulated sheathing system. While OX-IS offers exceptional thermal insulation, its benefits go beyond just enhancing R-values. The system is designed to bolster the performance of the overall building envelope, contributing to improved energy efficiency, indoor comfort, and the health of the structure.

    Moreover, OX-IS is easy to install, reducing construction time and labor costs. Its lightweight nature makes it ideal for a wide range of applications, from residential to multifamily and commercial buildings. Additionally, OX-IS is an environmentally friendly material made with more than 70% post-consumer recycled materials, contributing to greener structures.

    See the Stats

    According to a study by the Department of Energy, buildings account for approximately 40% of total U.S. energy consumption. By incorporating insulated sheathing, builders can do their part to help reduce this figure. The energy efficiency of the built environment is crucial to achieving global sustainability goals, and selecting the right products can have a big impact.

    On a micro scale, per individual structure, products such as OX-IS can reduce ACH50 blower door test results by 15 to 20 percent, some homes and buildings even greatly exceeding this number. In addition, the 4-in-1 insulated sheathing material has proven to reduce heating and cooling costs by anywhere from 20 to 40 percent, allowing owners to choose downsized HVAC systems when outfitting their home with a new unit. This, in itself, can save owners $200 to $350. Finally, when compared to using uninsulated OSB, 1-inch OX-IS delivers a 1,100% increase in R-value for the structure.

    Ultimately, selecting insulated sheathing materials leads to substantial energy savings over the life of a building and helps to create a reduced carbon footprint.

    Building Better

    Insulated sheathing plays a crucial role in improving the thermal performance of buildings. To meet the most stringent code requirements set by the International Code Council, many builders are using insulated sheathing in conjunction with standard batt or spray foam for even greater thermal performance.

    Integrated products such as OX-IS are helping builders nationwide meet these rising energy demands, while giving a much-needed boost to a building’s air and moisture resistance.

    By leveraging these innovative, integrated products, the industry can continue to create sustainable structures that meet the evolving demands of modern construction.

When installed continuously, insulation outboard the studs provides a myriad of benefits for owners and occupants.

    Continuous insulation is becoming a go-to choice for modern builders, and those that use it can tout its benefits to prospects and customers to earn more business. With initiatives such as 45L pushing green building practices and overall sustainability across the industry, using energy-efficient building materials is incentivized more than ever before.

    What is Continuous Insulation?

    Continuous insulation is installed continuously around the exterior walls of a building. Unlike traditional insulation methods that may have gaps and succumb to thermal bridging, continuous insulation provides a seamless thermal barrier, reducing heat transfer and improving energy efficiency.

    Many industry professionals refer to continuous insulation as a “big blanket” that surrounds the entire structure. Unlike traditional batt insulation that is split by the stud, there are no spaces or breaks in a continuous insulation installation for thermal energy to pass. Therefore, the material is popularly used in residential, multifamily, and even commercial applications to eliminate thermal loss.

    Advantages of Continuous Insulation 

    Continuous insulation offers several advantages over traditional insulation methods such as fiberglass batts, spray foam, or loose fill. It provides a higher level of thermal performance, helping to reduce heating and cooling costs for owners. When combined with high-performance windows and doors, continuous insulation is the perfect solution for lower HERS scores, landing these homes in the top percentile of energy-efficient homes across the country.

    Continuous insulation also improves overall occupant comfort by maintaining more consistent indoor temperatures. This is important in both summer and winter seasons and in any region or climate.

    In the summer, continuous insulation is designed to keep that prized conditioned air inside of the building. In the winter, the material can ease the workload of furnaces or other heating appliances in the home by maintaining warmer indoor temperatures for longer periods of time.

    Code Compliance for Today’s Builder

    Continuous insulation meets the needs of modern builders in several ways when it comes to sustainability and code compliance.

    One of the most considerable changes to the International Code Council’s 2021 guidelines are updates to insulation minimum R-values. For instance, in climate zone three (the Carolinas, Georgia, Alabama, and many more), builders of wood frame structures must meet R-values of 19 or 13+3ci or 0+15ci. And in many other regions of the United States, these values jump to R-20.

    For builders across the country who are accustomed to using cavity insulation only, supplementing with more efficient continuous insulation solutions can help to maintain compliance with these codes. It also helps eliminate the thermal breaks that are commonplace with cavity-only installations to help homes perform at a higher level.

    Continuous Insulation vs. Traditional Insulation

    Continuous insulation outperforms traditional insulation materials such as fiberglass, cellulose, and others. It provides a more effective thermal barrier and is much less prone to issues such as settling and moisture retention.

    Continuous insulation is often more durable than traditional insulation, and because it is less prone to moisture intrusion and mold growth, it can help extend the lifespan of the building envelope. This is crucial in minimizing the risk of sick building syndrome, which can have adverse effects on the occupants inside.

    Finally, one common misconception is that continuous insulation is only suitable for new construction. In reality, continuous insulation can be used in retrofit applications for existing structures that need a boost in thermal performance.

    21st-Century Insulation Options

    Innovations in insulation have led manufacturers to create integrated structural continuous insulation materials, also called structural insulated panels, or SIPs. These solutions truly cover the gamut when it comes to protection from the elements: air, moisture, thermal, and vapor intrusion.

    Not only does insulated sheathing provide a layer of insulation, but it adds in structural support, eliminating the need for builders to buy sheathing separately. For large-scale structures or production builders with a mass quantity of builds, these products help generate significant cost and labor savings. In all, the goal is to enhance the energy efficiency and durability of the building while removing the need for builders to have to shop from multiple suppliers. Products that include air and water barriers too, such as OX-IS, streamline vendor coordination even further.

    The Bottom Line

    Continuous insulation is a game changer in modern construction. Its ability to improve energy efficiency, reduce heating and cooling costs, and enhance overall comfort makes it a top choice for builders looking to meet the demands of today’s construction industry. Incorporating structural continuous insulation into a building project can lead to significant benefits in both the short and long term.

    For today’s builder seeking a reduction in costs, time, and manpower needs, particularly in an industry with a labor crunch and material price fluctuations, integrated structural continuous insulation serves as a viable solution.

    Bolstering OSB Installations with isoRED CI

    For the OSB Loyalists: Elevate Energy Performance Without Abandoning Your Sheathing

    We all have products or brands in our lives that earn our loyalty. For one reason or another, we don’t waver. It might be due to familiarity or fear of something new.

    The construction industry is notoriously resistant to change. This applies to builders and contractors using traditional construction methods and products such as oriented strand board (OSB) and standard sheathing options. The product is widely available and effective as structural sheathing to provide strength and rigidity to a building exterior. However, there are higher-performing options on the market, and OX Engineered Products is on the leading edge of their development, whether a builder wants to stick with traditional OSB or not.

    Bucking the Trend

    OSB has been used for sheathing in construction for decades since it was invented in 1963. Since then, OSB has gained popularity, extensively utilized for wall sheathing, floor underlayment, roof covering, and I-joists in both commercial and residential buildings. It remains popular because of its affordability (despite fluctuating market prices), availability, ease of installation, and durability.

    For exteriors, OX took this popular material and combined it with other necessary building control layers, including continuous insulation and air and water barriers. These innovative solutions are ThermoPLY and OX-IS, integrated 3-in-1 and 4-in-1 solutions, respectively.

    These products enhance the performance of exterior walls with regard to thermal performance and moisture and air management. ThermoPLY (which comes without the insulation layer) has gained significant ground in the construction industry, being installed on more than five million homes across the country.

    But what about builders who do not want to veer away from OSB and do not need the structural layers found in ThermoPLY and OX-IS?

    Enhance Performance Sticking with Traditional Materials

    Builders reluctant to switch to the aforementioned OX-IS or ThermoPLY integrated products can still significantly enhance building performance while using their OSB sheathing.

    IsoRED CI is a rigid polyiso insulation that can add much-needed R-value for residential and light commercial applications. With the ability to be affixed to wood, metal, masonry and concrete, IsoRED CI can be used for practically any job to increase energy efficiency in ceilings, interior walls, and exterior walls regardless of sheathing used. The product also comes with water-resistant facers that provides the first line of defense against moisture intrusion. In a nutshell, builders can stick with OSB but meet ever-changing building code requirements that have strict R-value mandates. The product also eliminates the need to make an additional trip around the home or building to install a layer of housewrap, saving time on the job site.

    IsoRED CI incorporates best-in-class, long-term R-value performance to enhance building efficiency. Acting as a comprehensive system, it provides thermal, air, and vapor control layers without a structural layer, enabling builders to continue using OSB or the sheathing of their choice. All in all, IsoRED CI’s thermal properties help ensure that conditioned spaces remain consistently comfortable whether battling summer highs or winter lows.

    When challenging building codes need to be met, incorporating a product such as IsoRED CI is a no-brainer.

    For builders hesitant to adopt some of the more innovative, integrated products on the market such as OX-IS or ThermoPLY, IsoRED CI stands out as viable solution. The rigid polyiso insulation helps to meet thermal code compliance, catering to the evolving needs of the construction industry for the new wave of talent and old-school OSB loyalists.

    The Polyiso Promise

    Polyisocyanurate Insulation Helps with Code Compliance, Energy Savings, and Earning Financial Perks.

    Providing advanced thermal protection for the structures in which we live, work, and play is proving to be even more crucial than we ever considered. According to a 2023 article on Euronews, new research suggests that reaching net zero emissions could prolong people’s lives significantly, and that properly insulated walls help to limit indoor air pollution that negatively impacts the health of occupants inside.

    Occupant health is priority number one. But how can builders use innovative insulation solutions to save on costs, build more efficiently, and meet the evolving energy codes designed to create a more sustainable built environment?

    Polyisocyanurate insulation, renowned for its closed-cell composition, serves as a linchpin in bolstering energy efficiency for residential, multi-family, and commercial buildings. Its rigid form with closely bonded cells not only acts as an air barrier but also provides moisture resistance, which is critical in keeping internal structural components and occupants healthy. When combined with integrated control layers and a structural layer, the material crosses into what can only be categorized as the future of building science.

    Proven Polyiso Performance

    Weatherization systems, especially those incorporating closed-cell polyiso insulation such as OX-IS panels, have proven to be instrumental in optimizing energy efficiency and indoor comfort. These types of systems eliminate thermal bridging in both wood and metal wall studs, preventing the movement of heat and energy through the structure. This is especially vital during the peak of summer or the frigid depths of winter when temperatures are at an extreme.

    Weatherization systems that utilize polyiso insulation provide much higher R-values compared to alternative products such as spray foam, XPS foam, or other open-cell insulation solutions. In fact, OX-IS is offered in three thicknesses ranging from 0.50² to 1.70² and provide thermal R-values of 3, 6, and 10.

    OX-IS fortifies the entire wall system when properly taped, seamed, and flashed. By featuring an integrated structural layer along with air and water barriers, OX-IS eliminates the need to make multiple trips around a structure to complete the installation. Once installed, an OX-IS wall is a tighter wall. This leads to a better blower door score, enhancing HVAC system performance and reducing long-term energy costs.

    Affordably Meet Stringent Energy Codes

    Structural continuous insulation wall panels allow builders to affordably tackle code changes and meet the most current IECC insulation requirements. These weatherization systems also help ease specification planning for project teams looking to achieve ENERGY STAR® or the requirements for the Department of Energy’s Zero Energy Ready Home (ZERH) standards.

    Where should builders look to get up to speed on what’s expected of them with regard to insulation and a building’s thermal performance?

    Start with International Energy Conservation Code section R402.1.2, which is dedicated to a building’s thermal envelope. Understanding the options available to a builder, including different continuous insulation thicknesses and options for R-values, helps to ensure compliance with the latest requirements.

    Adhering to these code standards through the implementation of all-in-one weatherization solutions can help builders earn significant money back for building sustainably through the 45L tax credit program, applicable to both residential and multi-family builders.

    In particular, builders of single family homes that meet the ENERGY STAR Certified Homes V3.1 (moving to V3.2 in 2025)

    program’s 2021 IECC prescriptive envelope standards are eligible for a federal tax credit of $2,500 per home.

    On a parallel path, builders who adhere to the ZERH program can earn up to $5,000 back in tax credits per build.

    In addition, builders should maintain cognizance of local and regional rebates extended by utility providers, which may offer substantial cash incentives contingent upon meeting these ENERGY STAR standards or achieving a high HERS score with significant Kilowatthour (KwH) savings. In these instances, adding a layer of continuous insulation to exterior walls will improve the performance of the home and translate to a rebate check with a bigger number on it. In an era of rising material and labor costs, these financial returns can impact a builder’s bottom line.

    Sealing the Deal with Proper Installation

    In the long term, the benefits of incorporating polyiso insulation and weatherization systems into a construction project are substantial. By eliminating thermal bridging, the building’s thermal envelope is fortified, reducing the load on heating and cooling systems. This translates to significant energy cost savings for owners. Not only do owners save, but builders can stick with 2×4 stud construction and still achieve code compliance without having to switch to a heavier, more expensive 2×6 wall. Finally, builders stand to gain financially through various rebate programs such as the federal 45L tax credit and local incentives tied to energy efficiency certifications and HERS ratings.

    The adoption of polyiso insulation and weatherization systems represents a step in the right direction toward achieving the most energy-efficient, sustainable building practices. With its impressive performance attributes and compatibility with evolving industry standards, polyiso is poised to play a central role in the construction landscape of the future.
