Fire Rated Rigid Foam Insulation

Thermax sheathing specially designed to hold a class a fire rating.

Fire rated rigid foam insulation.

Easy to handle cut and install without the difficulties of foil facing. Available with tough film facers for added damage resistance. Icynene is committed. Thermal insulation should only be used and installed in strict accordance with local build.

Rigid pir insulation boards fire rated future foams pir board is a non structural polyisocyanurate insulation board consisting of a rigid insulation core sandwiched between two high performance foil facings to create a tough durable light weight board that has high insulation properties with a high level of fire performance. With thicknesses varying from 1 4 5 inches resista polyiso uses firestone s proprietary isogard foam technology to create an impressive insulating value per inch which can translate into significant energy savings. Thermax sheathing is a nonstructural rigid board insulation with a glass fiber infused polyisocyanurate foam core laminated between 1 0 mil smooth reflective aluminum faces. Icynene spray foam insulation products have the flame spread and smoke developed indexes required have been tested in accordance with and comply with the acceptance criteria of nfpa 285 and there are many wall and ceiling assemblies that contain icynene products and are fire resistance rated in accordance with astm e 119.

Rigid foam insulation is a more effective air barrier than batts or blown in insulation especially if the seams between sheets are carefully sealed with caulk canned spray foam or tape. Fire rated expanding foam can provide up to 240 minutes of fire rating and is used as an efficient seal against gas and smoke. Resista polyiso is an economical choice offering protection against fire wind and mold. Since most fire codes call for a minimum of half hour fire rating over foam insulations paneling would probably not provide a sufficient fire barrier over the foam insulating board.

Rigid foam is routinely used to insulate the interior or exterior of foundation walls. On above grade walls exterior foam improves the performance of a wall. Thermax sheathing can be installed exposed to the. Used in fire rated exterior wall assemblies for application in office buildings schools shopping centers and more.

Readily combines with blanket type insulation for greater r value. The glass fiber reinforcement provides improved fire performance and dimensional stability. Expanding spray foam insulation has grown fast as one of the most popular options over time because of its cost effectiveness.
