Stock cabin insulation prioritizes cost over performance, leaving enthusiasts with drone, road noise, and heat transfer that kills focus on long drives or track days. Heatshield Products' db Shield attacks all three with a 1/2-inch open-cell polyester-based polyurethane foam that absorbs sound, resists heat, and installs in minutes with no special tools.
Maximum absorption in minimal thickness. The uniform cell structure and optimized porosity of the open-cell foam pull cabin noise out of the air column rather than simply deflecting it. At just 1/2 inch thick, db Shield fits tight door panels, floor pans, and engine bays without eating into interior clearance or requiring panel trimming.
Built to survive the environment it works in. A polymer surface treatment protects the foam from humidity, chemicals, and heat across a continuous operating range down to -45°F and up to 230°F intermittent. The same resistance that keeps it intact in an engine bay makes it equally reliable behind door skins or under carpet on a daily driver or heavy-duty truck.
Adhesive backing simplifies installation. The pressure-sensitive adhesive sticks to any clean, smooth surface, eliminating the need for adhesive sprays, mechanical fasteners, or professional installation. Cut it to shape, peel, and press.
