Quality Rigid Foam Insulation Sheathing for Mid-Atlantic Builders
The THERMAX system is a rigid foam insulation that can be used for a variety of applications, including concealed and exposed applications, as well as above and below grade.
Appropriate for both commercial and residential insulation projects across the Mid-Atlantic, THERMAX sheathing:
- Is ideal for walls including non-vented crawl spaces, interior walls of metal buildings, and interior basement walls
- Can be installed without a thermal barrier and can also be used with hourly rated assemblies
- Features reinforcing facers and chemical modifiers contributing to fire resistance and durability
- Has a glass-fiber-infused polyisocyanurate foam core laminated between aluminum facers on both sides
- Carries a Class A fire rating and reduces condensation due to its low perm rating
- Comes in a variety of thicknesses (1/2” to 2”) and R-values (3.3 to 13.0)
- Features square or shiplap edges, depending on the product chosen
THERMAX sheathing from Dow is lightweight and easy to install and can be easily cut using a knife or saw. It can be installed on both walls and ceilings including girts, steel studs, block, wood, tilt-up, purlins, trusses, and bar joints.
