SEALTECH Heavy-Duty 24 in. x 20 ft. 3mm Thick Reflective Insulation Roll for Soundproofing Thermal Shield Use

This reflective insulation roll cuts heating and cooling costs by reflecting 95% of radiant energy, working as a radiant barrier in homes, barns, workshops, and outbuildings. The roll measures 24 inches wide by 20 feet long with a 3mm closed-cell foam core sandwiched between fire-retardant engineered foil layers. Closed-cell foam stays dimensionally stable across humidity and temperature swings, holds its shape without settling out of position, and doesn't host rodent nesting or moisture wicking like fiberglass batts. The foil faces act as a built-in vapor barrier, so no separate poly sheeting is needed for moisture-prone applications. Approved for indoor and outdoor use across attics, walls, ceilings, garage doors, metal roofs, steel buildings, and concrete floor underlayment. The closed-cell core absorbs mid-frequency sound to reduce noise transmission between rooms or from outside. Non-toxic, non-allergenic, and fiber-free - installs without protective gear, won't irritate skin, eyes, or airways. The roll trims with utility knife or scissors and fastens with staples, foil tape, or spray adhesive depending on the application surface. Silver foil surface stays reflective without flaking or oxidizing over the product life.
