SmartSHIELD -1.5mm 48" x200ft Reflective Insulation roll 800 Sq. Ft., Foam Core Radiant Barrier, Thermal Insulation Shield - Engineered Foil

Works very well--insulated my tin pump house. Easy to do.

The product worked excellent reducing energy losses in my garage insulation project.

Excellent product and very nice to work with... what are difference made in our crawl space... Like the product so much and ended up buying it twice... extremely durable.

Put this between my subfloor and carpet in a remodel of a room with a crawl space underneath (northern climate). It was easy to install and it really helps keep the heat and/or cool in the room, depending on the season of the year.

Chose the 1.5 mm since there wasn't a lot of clearance near the back door. It works well at reteaning heat. Used two layers in other part of the sunroom under the carpet. Went from cold coming through enough to feel it a few feet above the floor to now the cold can only be felt went stepping on the carpet.

Easy to work with. Would buy again.

Thin, had to double it up to be really effective in windows during the Texas cold snap.

Outstanding Radiant Barrier and much easier to install than the bubble type.
