Is NASA TECH on Sale? November 2026

Questions and answers

What is NASA TECH reflective foam core insulation made of?

It is a closed-cell polyethylene foam core bonded to a reflective white facing. The facing reflects radiant heat while the foam slows conductive heat transfer. Rolls are flexible and cut with a utility knife.

What does the self-adhesive backing stick to?

The peel-and-stick backing bonds to clean, dry, rigid surfaces such as garage doors, metal building panels, ductwork and stud faces. Press it firmly and avoid stretching the roll as you lay it. It is not meant for dirty, damp or dusty surfaces.

Where is this insulation used?

Common uses are garage doors, attic rafters, metal buildings, pole barns, storage sheds, water heater blankets and HVAC duct wraps. It works as a radiant barrier and a vapor retarder in those spots. It is not a substitute for batt insulation in a conditioned wall cavity.

Does the white facing need a fire rating check?

Check the roll's label for its flame spread and smoke ratings before installing it in a living space or near a heat source. Foam core products vary, and local codes may require a thermal barrier over foam in occupied rooms. Keep the facing exposed where it is meant to reflect radiant heat.

How is the roll installed and cut?

Unroll it, measure to length, and cut with a sharp utility knife against a straight edge. Leave a small gap at edges for expansion and seal seams with foil tape. The 24 in width suits stud and joist spacing; wider rolls cover garage doors faster.
