- Is this worth it for a garage door?
- Yes for radiant heat and drafts on a standard door, since one roll covers about 34 square feet. It is thin foam, so expect modest insulation value, not the performance of rigid board.
- What is the R-value?
- BXI does not list an R-value for this 0.2 inch foam. Treat it as a radiant barrier and air gap filler, not a primary insulator.
- Can I cut it to size?
- Yes. The foam cuts with scissors or a utility knife, and the peel-off backing lets you stick pieces to panels, doors and ducts.
- Will the adhesive hold on a rough wall?
- It sticks best to clean, smooth, dry surfaces. On concrete, brick or dusty wood, clean first and add mechanical fasteners or tape at the edges.
- What comes in the box?
- One 13 by 157 inch reflective foam panel, about 0.2 inch thick, plus a bag. Coverage is about 34 square feet.
- When is it cheapest?
- The best new price is $39.99 at Amazon as of November 4, 2026. Check the price history before buying, since small insulation rolls swing with seasonal demand.
