TWCUSEP Aluminum Foam Insulation Sheet vs Insul-EZ 4x4 Foam Insulation Sheet

Buy the TWCUSEP roll if you are covering a vehicle floor, van wall or long run and want a thin, foil-faced, peel-and-stick barrier in one continuous piece. Buy the Insul-EZ sheet if you need a thicker, rated thermal sheet for a flat panel or duct and want a published R-value. The TWCUSEP is a 5 mm closed-cell foam with an aluminum face, so it deadens sound and blocks radiant heat but adds little R-value. The Insul-EZ is 3/4 in thermal foam rated R-3.0 with a stated temperature range, so it insulates better per square foot but comes only in 4 ft squares and is heavy and stiff to work with.

• Choose the TWCUSEP if you are lining a van, truck, RV or car and want a long, thin, self-adhesive foil-faced roll that cuts easily and follows curves.
• Choose the Insul-EZ if you need a thicker sheet with a published R-value for a flat panel, duct or equipment surface and can work with 4 ft squares.
