SkyFlex Radiant Barrier

Key Features: • Dual aluminum layers reflect radiant heat, boosting energy efficiency • Acts as radiant barrier and Class I vapor retarder (0.01 perms) • Excellent air barrier (air permeance < 0.02 L/ (s·m²) @ 75 Pa) • Durable, flexible, and puncture-resistant for easy installation • Adds R-value with enclosed air spaces (up to R-2.9) • Installs twice as fast as rigid air ...

FI-FOIL ® air barriers significantly enhance building efficiency by controlling air leakage, improving indoor air quality and energy savings. SkyFlex ™, a versatile and easy-to-install solution, offers superior air infiltration and exfiltration control, making it an ideal choice for achieving high-performance, energy-efficient building envelopes in both new and retrofit projects.
Key Details About Skyflex Radiant Barrier

SkyFlex is a flexible sheet air barrier used to separate conditioned air from any given unit or adjacent unit of unconditioned or partially conditioned space in residential and commercial buildings. SkyFlex air barrier Low-e surfaces provide additional value to reduce radiant heat transfer when exposed to air films or enclosed air spaces in wall systems. FI-FOIL Solid Air Barrier , 125 ft ...
SkyFlex ™ is a tough, flexible air barrier for use in residential and commercial building applications. The product consists of two layers of aluminum deposited on a layer of woven polyethylene. When exposed to air films or enclosed air spaces in building cavities, SkyFlex's low-emittance exterior layers reduce radiant heat transfer. SkyFlex ™ is designed to be used as a primary air ...

Useful Notes on Skyflex Radiant Barrier
The newest FI-FOIL® flexible sheet air barrier , SkyFlex ™ VT (Vapor Transmitting), is designed for use in walls where conditioned space abuts unconditioned or limited conditioned space. The SkyFlex ™ VT air barrier with low emissive (Low-e) surfaces reflects 80 percent of radiant heat to keep buildings cooler in summer and warmer in winter.
A tough, flexible air barrier insulation for both residential and commercial buildings, Skyflex ™ consists of two layers of aluminum foil laminated to a layer of woven polyethylene. When exposed to an enclosed air space within the wall cavity, Skyflex ™ low-emittance (low-E) exterior layers help reduce the radiant heat transfer to gain a more continuous insulation effect.
