Exposed Walls? You’re Covered With THERMAX™!

For metal buildings with low humidity (50 percent or less), Dow Building Solutions has got you “covered.” THERMAX™ polyisocyanurate insulation products for exposed interior walls help reduce thermal loss and moisture buildup.

THERMAX™ insulation products are an ideal choice for metal buildings (conventional or modular construction) that require an attractive, low-maintenance interior wall. The products have a solid core of polyisocyanurate insulation, integrated on both sides by facers of aluminum and/or acrylic-coated aluminum. These easy-to-clean facers add strength, durability, moisture control and aesthetic value. White acrylic facers can also help reduce light energy costs.

The distinct THERMAX™ foam core offers excellent thermal performance, and it is specially treated to offer fire resistance. THERMAX™ products can be left exposed to the interior in most metal building applications, and all THERMAX™ products are pressure-washable with the exception of THERMAX™ Sheathing.

THERMAX™ products are ideal for agricultural, commercial, industrial and residential applications.
