RainBarrier

RainBarrier® Rain Screen & Cavity Wall Insulation

Thermafiber RainBarrier products are designed for exceptional performance in rain screen and cavity wall construction applications. RainBarrier 30 & 45 provide energy saving continuous insulation (ci), fire protection, and acoustical control while efficiently draining water from a wall cavity system. RainBarrier products are non-combustible and compatible with common wall ties and air barrier systems.

RainBarrier has several distinct advantages over rigid and spray foam insulation in these types of construction:

1. Non-combustible and fire resistant. RainBarrier can withstand temperatures over 2000°F for over 5 hours. In the event of a fire, mineral wool will not burn or release toxic smoke and gasses.    
2. Sustainability. With up to 90% recycled content, RainBarrier offers the highest available recycled content of any commercial insulation. No CFC or HCFC blowing agents. Energy saving R-value up to 4.2 per inch of thickness. 
3. Permeable. In a vapor permeable system, RainBarrier allows the building to breathe as it is designed without sacrificing R-value. In a non-permeable system, RainBarrier allows the vapor barrier to perform without creating additional traps for moisture in the wall cavity.
4. UV resistant. RainBarrier is ideal for use in open joint systems where UV rays can degrade foam insulations.
5. Easy to fabricate and install. Semi rigid mineral wool can conform to jobsite irregularities much better than rigid insulations to ensure a continuous thermal barrier.  
6. LEED® Credits. RainBarrier contributes to 33 LEED credits across 4 categories.
