Our take on the Reflective Foam Core Insulation Garage Door White Foil 24 Inch x 9ft AD5 R8

This is a 2 ft x 9 ft roll of reflective foam core insulation for garage doors, made by bonding closed-cell foam between a metalized aluminum film and a white vinyl face. It is rated R8 and reflects about 97% of radiant heat while emitting under 3%. It is Class 1/Class A fire rated and passed ASTM E84 and ASTM E2599. It suits homeowners who want to cut radiant heat through a garage door without a full door replacement. Against fiberglass batts it is thinner, lighter and easier to staple, but it adds less bulk insulation and only works as a radiant barrier plus modest R-value.

Pros
  • Reflects about 97% of radiant heat
  • R8 rating adds real thermal resistance
  • Closed-cell foam resists compression and collapse
  • Staples hold without tearing
  • Class 1/Class A fire rated, ASTM E84 and E2599 tested
  • Lightweight and easy to cut and install
Cons
  • R8 is modest next to batt or rigid board insulation
  • Foil and vinyl faces can tear or crease if handled roughly
  • Needs a clean, flat surface and careful sealing at edges
  • Radiant barrier performance depends on an air gap

Questions and answers

What does R8 mean here?
It is the stated thermal resistance of the foam core. R8 is modest, so treat it as a radiant barrier plus light insulation, not a substitute for a well-insulated door.
How does it compare with fiberglass garage door kits?
It is thinner, lighter and cleaner to handle, and it reflects radiant heat instead of trapping it in bulk. Fiberglass kits usually give a higher R-value but are bulkier and messier to install.
Can I cut it to fit door panels?
Yes. The foam core cuts with a utility knife, and the vinyl face holds staples. Measure each panel and leave room for the door's hinges and hardware.
Does it need an air gap to work?
A reflective surface works best with an air space between it and the hot side. Mounting it directly against the door still helps, but performance is lower than a properly gapped install.
Is it fire rated?
It is listed as Class 1/Class A and tested to ASTM E84 and ASTM E2599. Check local code for garage insulation requirements.
What is in the roll?
One 2 ft x 9 ft roll of foam core insulation with a metalized aluminum face and a white vinyl face.
