This is a 6mm XPE closed-cell foam wall panel with a peel-and-stick adhesive backing and an aluminum foil face. It is sold as a thermal barrier and sound dampener for walls, ceilings, garages and rented rooms, and it cuts with scissors. It is a thin surface layer, not a structural insulation board, so it adds modest thermal resistance and echo control rather than replacing batt or rigid foam insulation. Compared with rigid foam boards it is far easier to install on finished walls, but it offers less R-value per inch and no vapor barrier rating.

This peel and stick foam wall panel is a thermal insulation board made from 6mm XPE foam with an aluminum reflective backing. It has a yellow protective film on the face and a self-adhesive layer on the back.
To install, peel the release liner and press the panel flat against glass, concrete, or fresh paint. It cuts with scissors to fit around outlets and sharp corners. The surface is moisture safe and wipes down without damage.
The closed-cell foam core helps retain heat and reduces convective heat loss behind furniture and painted drywall. The aluminum backing reflects radiant warmth back into the room. The panel also dampens sound to cut echo on hard walls and covers scuffed drywall and cracked plaster.
