Reflective Insulation

Energy Efficiency Starts with the Right Barrier

At Metal Builders Supply, we offer high-quality reflective insulation products designed to reduce heat transfer, lower energy bills, and increase comfort in both residential and commercial structures. Whether you're building new or improving an existing space, our insulation is a smart, cost-effective way to improve energy efficiency year-round.

What Is Reflective Insulation?

Reflective insulation is made with a reflective facing—typically aluminum foil—that reflects radiant heat rather than absorbing it. Unlike traditional fiberglass insulation, reflective insulation works by reducing heat gain in hot weather and heat loss in cold conditions. It’s lightweight, easy to install, and highly effective when used in attics, walls, floors, or roofs.
