- Is this worth it compared with foam board?
- For reflecting radiant heat off a garage door or attic roof, yes, and it costs far less. For insulating a heated room, foam board or fiberglass does more because it blocks conducted heat.
- How much area does one roll cover?
- 24 inches by 10 feet is about 20 square feet. Measure your garage door or window openings and buy several rolls if needed.
- Can I put it directly against a wall?
- Foil works best with an air gap on the reflective side. Stapling it to studs or furring strips leaves that gap; pressing it flat against drywall loses most of the benefit.
- Is it fire rated?
- The listing gives a B2 fire class, a European rating for normally flammable building materials. It is not a non-combustible barrier, so keep it away from open flames and heat sources.
- When is the price lowest?
- At $8.88 at eBay as of November 4, 2026, it is already near the bottom of its range. Insulation rolls often dip in fall and early winter, so watch for seasonal markdowns.
