Description
Description

The THERMAX™ Brand Insulation is a polyisocyanurate rigid board insulation for interior and exterior continuous insulation. THERMAX products include an innovative core surrounded by a tough exterior facer of a variety of ranges and aesthetic appearance. The core is produced with free-rise technology, exclusively offered by Dow— providing a homogenous core with a finer cell size and better cell orientation reducing wormholes and knit lines for one of the highest R-values available (R-6.5 at 1"), outperforming in even cold temperatures. THERMAX is also engineered with unique fiberglass reinforced core for enhanced fire performance making it the only polyisocyanurate insulation to have FM 4880 approval and can be used on walls and ceilings, up to 30 ft.

Features
  • Provides continuous insulation on the interior or exterior
  • One of the highest R-values available (R-6.5 at 1")
  • Features a distinct free-rise technology for better product consistency, durability and fire performance over generic polyisocyanurate insulations
  • Approved for fire exposure
  • Contains UV-stable technology and can remain uncovered up to six months
  • It reduces the potential for condensation within the wall assembly resulting in long lasting performance due to its low perm rating and high insulating value
  • Eliminates the extra step of installing a membrane or building wrap
  • Can be installed exposed to the interior without a thermal barrier
