Trying to keep your attic, garage, workshop, or metal building cooler in summer and warmer in winter? This rFoil single bubble insulation can help. It's a reflective radiant barrier that bounces back up to 96% of radiant heat – so it helps regulate temperature without needing super thick traditional insulation. The roll is 48 inches wide by 125 feet long, giving you 500 square feet of coverage. It's made with a layer of bubbles sandwiched between reflective foil surfaces, which also adds a bit of R-value and helps reduce condensation. It's lightweight, easy to cut and install (no itchy fibers!), and has a Class A fire rating. Use it in attics, under roofs, on walls in basements or crawl spaces, or even under concrete slabs. Great for both new construction and retrofitting existing spaces. A cost-effective way to boost your insulation and maybe even lower those energy bills.
