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.
