Looking to cut down on heating and cooling costs? This reflective insulation roll is a great place to start. It's a 3mm thick sheet with a foam core sandwiched between two layers of reflective foil. The idea is simple: it reflects radiant heat—up to 95% of it! That means in summer, it bounces the sun's heat away from your attic or walls, and in winter, it helps keep warmth inside. The roll size is 8 feet by 20 feet, giving you plenty to work with. It's also moisture and vapor resistant, so it's good for areas like crawl spaces, garages, or behind walls. Plus, the foam core adds some soundproofing benefits, quieting outside noise. The material is fire-retardant, non-toxic, and doesn't irritate skin. It's lightweight and easy to cut with a utility knife, and you can staple or tape it into place. Perfect for DIYers tackling attic insulation, garage walls, or even RV and van conversions. A cost-effective way to improve your home's energy efficiency and comfort.
