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

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).
Less Cost… typical savings of 25% versus fiberglass batts.
Stops Radiation…as a reflective insulation, VR Plus Shield’s multiple layers
separate to create three reflective air spaces to virtually eliminate heat transfer.
Less Storage Space…500 square foot rolls are easy to store and transport.
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.
Green Building Material…contributes to Green Building Certification credits for
Energy Efficiency.
Offered in 16” and 24” width rolls with tape tab for installing over
Metal Framing or with staple tab for Wood Framing.
VR 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.
How does Flash & Foil™ work?
Step 1: Spray the desired thickness of foam
insulation on the inside of the frame wall
which seals the joints and provides thermal
protection by reducing air infiltration and
adding 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 layer
of foam (flash) is used to air seal the cavity.
Step 2: Apply VR Plus Shield reflective
insulation (foil) to the face of the studs. The
three layers of VR Plus Shield expand to
form reflective air spaces in the remaining
portion 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.
