Reflective Insulation Sheets, 16 Pack, 6 mm 1.22 x 0.61 m

Double reflective insulation sheet helps reduce heat transfer year-round, keeping spaces cooler in summer and warmer in winter. This 16-pack of double-sided aluminum foil radiant barrier panels uses a four-layer build with dual air bubbles to slow conductive heat and reflect radiant heat. Cut-to-fit 2 x 4 ft sheets make it simple to line windows, garage doors, roofs, attics, sheds, and DIY projects where temperature swings and drafts waste energy.

Upgrade your insulation where it matters most—hot windows, drafty garage doors, roof spaces, and metal surfaces that quickly radiate heat. These lightweight radiant barrier insulation sheets are designed for fast measuring, cutting, and placement, so you can tackle spot fixes or larger coverage without bulky rolls. Use them for home improvement, workshop comfort, or seasonal temperature control projects when you want efficient coverage per pack and clean, cut-to-size installation.
