Unique Air Barrier Insulation Adds R-value for Less

As demand grows for air barrier insulation, more builders and contractors are choosing FI-FOIL^® Skyflex™ due to exceptional thermal performance, durability, and improved productivity that’s leading to savings for many—proving to be a cost-effective solution for walls exposed to extreme temperatures of the summer and winter months.

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.

Using air barrier insulation creates more air-tight space to significantly improve performance and comfort in common areas exposed to excessive temperatures:

⦁ Knee Walls

⦁ Behind Bath Tubs

⦁ Attic Stair Wells

⦁ Bonus Rooms

⦁ And More

Increasingly, builders and contractors are using air barrier insulation to better seal the building envelope. This not only improves performance but also supports sustainability and efforts to reduce our carbon footprint.

When one or both sides of Skyflex™ air barrier is exposed, thermal resistance of the wall increases. Air space matters. When used with one side exposed to an attic, Skyflex™ adds an additional 1.7 R-value to the system. When installed with 1.5” of enclosed air space, Skyflex™ adds 2.6 R-value and when installed with .075” of enclosed air space, it adds an additional 2.9 R-value.

Skyflex™ is a superior reflective insulation. In comparison to Thermo-ply, a commonly used air barrier product, Skyflex offers an improved value proposition due to being more compact, easy to transport, and remarkably easy to install. FI-FOIL^® Skyflex™ offers an opportunity to improve productivity and savings on labor and material. And, for many, Skyflex™ offers a high performing, economically smart alternative to Thermo-ply—costing 20% less for material alone.
