The benefits of Thermo-Ply vs. OSB |
|
| Thermo-Ply Structural Sheathing by OX | OSB (Oriented Strand Board) |
| No added asphalts, formaldehide,phenols or CFCs | Made from wood chips, may contain formaldehyde. Formaldehyde is a probable human carcinogen. |
| Stable pricing | Commodity, rapid price fluctations |
| Extrusion Coated WRB on both sides | Requires additional WRB layer |
| High moisture tolerance | Low moisture tolerance. Significant swelling when wet, which could produce mold. |
| Tight seal controls air infiltration for lower ACH | Average air infiltrations perfomance |
| Custom sizes and private labeling avaliable | Typically no custom sizes or print available |
| 13 lbs for 4’x8’ sheet (RED) | 45 lbs for 7/16’’ x 4’8’ sheet |
| PE-stamped in all 50 states and Canada | Has no PE stamp or independent engineering testing/certification |
| Covered by warranty | No warranty |
