Our reflective insulation is a safe, easy-to-use, thermal insulating material that provides cost effective, high efficiency performance for a wide range of applications. The Reflectix® Double Bubble product consists of two outer layers of a highly reflective material that reflects 96% of the radiant energy that strikes it's surface. This material is bonded to a tough layer of polyethylene for strength. Two inner layers of insulating bubbles resist conductive heat flow while a center layer of polyethylene give Reflectix® high reliability and strength. The Double Bubble product is recommended when the application calls for enhanced condensation control, greater strength and higher thermal qualities.
