Our take on the XTEMP 3mm HVAC Duct Wrap Garage Reflective Insulation Foam

This is a 2 ft by 25 ft roll of double-sided reflective foil bonded to a 3mm closed-cell foam core, sold as a radiant barrier for garages, attics, walls and duct wrap. It reflects about 97% of radiant heat, is Class A fire rated to ASTM E84, and staples, glues or cuts with a utility knife without the itch of fiberglass. It suits DIYers insulating a garage door, attic rafters, duct runs or a shed. Against bubble-foil rolls it is thicker and holds staples without tearing, but at 3mm it is a radiant barrier, not a bulk insulator, so it needs an air gap and does little for conducted heat on its own.

What reviewers say

Questions and answers

Does this actually insulate, or only reflect heat?
It is a radiant barrier first. The foil blocks radiant heat and the 3mm foam adds a small R-value. For real temperature swings you still need bulk insulation behind it.
Can I put it directly against a garage door or wall?
Yes for the door panels, but leave an air gap on at least one foil face for the radiant barrier to work. Direct contact with both faces cuts its reflective performance.
Is it safe to handle without gear?
Yes. It is fiber-free and non-carcinogenic, so no respirator or protective clothing is needed. Gloves still help with sharp cut edges.
How much area does one roll cover?
A 2 ft by 25 ft roll covers 50 square feet. Measure your garage door panels or rafter bays before ordering, and add for overlaps.
Can it wrap HVAC ducts?
Yes, it is sold for duct wrap. Seal seams with foil tape and keep the outer foil face clean so it keeps reflecting.
Does it meet fire code for exposed use?
It is Class A rated to ASTM E84 and passes ASTM E2599. Check your local code for exposed foam in occupied spaces.
