Hybrid Spray Foam and Reflective Insulation System – Fi-Foil® Company Introduces…

What is Flash & Foil?

Fi-Foil’s new Flash & Foil Frame Wall Insulation is an improved insulation solution designed to save you money. This solution has advantages to Flash and Batt systems.

Combine Fi-Foil’s VR Plus Shield® Reflective Insulation with spray foam insulation to reduce costs and provide code-compliant R-Values in any frame wall construction.

Drop the Batt - Drop the Batt - Flash & FoilFlash & Foil™!™!

Flash & Foil™ is a National Solution for Frame Wall Foam Insulation

Why replace fiberglass batt with Fi-Foil’s VR Plus Shield® Reflective Insulation?

1) Code Compliant Wall R-Values…R-values for Flash & Foil in 2 x 4 inch wall range from R-11 to R-19, based on the foam manufacturer’s R per inch and the thickness of the foam. A complete table of R-Values determined by the thickness and type of spray foam to follow on separate slide (Table 1).

2) Less Cost… typical savings of 25% versus fiberglass batts.3) Stops Radiation…as a reflective insulation, VR Plus Shield’s multiple layers

separate to create three reflective air spaces to virtually eliminate heat transfer.

4) Less Storage Space…500 square foot rolls are easy to store and transport.5) Vapor Retarder…available in Hi-Perm (perforated version) that allows vapor

transmission and in Standard (non-perforated version) that functions as a vapor retarder, if required by code.

6) Green Building Material…contributes to Green Building Certification credits for Energy Efficiency.

VR Plus has a Class A Flammability RatingVR Plus has a Class A Flammability Rating

Also available in Hi-Perm (perforated version) to allow vapor transmission or in Standard (non-perforated version) to perform as a vapor retarder.

Offered in 16” and 24” width rolls with tape tab for installing over Metal Framing or with staple tab for Wood Framing.

How does Flash & Foil™ work?

Step 1: Spray the desired thickness of foaminsulation on the inside of the frame wallwhich seals the joints and provides thermalprotection by reducing air infiltration andadding thermal resistance. Instead of 3-1/2”or 5-1/2” of spray foam in a 2 x 4 inch or 2 x 6 inch cavity respectively, a thinner layerof foam (flash) is used to air seal the cavity.

Step 2: Apply VR Plus Shield reflectiveinsulation (foil) to the face of the studs. The three layers of VR Plus Shield expand to form reflective air spaces in the remainingportion of the 2 x 4 inch or 2 x 6 inch cavity.

REQUIRES 1-1/2 INCH AIR SPACE FOR VR PLUS TO EXPAND INNER LAYERS

How are R-Values calculated for Nominal 2 x 4 inch and 2 x 6 inch Wood Frame Wall Cavities insulated with VR Plus Shield® and Spray-applied Cellular Foam Plastic Insulation?

The thermal resistance (R-values) for combinations of Fi-Foil VR Plus Shield Reflective Insulation and spray-applied cellular foam plastic insulation have been calculated using a procedure published in ASTM STP 1116.
