3.5 mm thick bubble-patterned vinyl insulating film – thermal barrier, suitable for doors, windows and aquariums, 60 cm x 1 m

【Reinforced Double-Layer Insulation Structure】This insulation panel/layer consists of five layers: a double-sided aluminum vapor barrier and thickened EPE (polyethylene terephthalate) insulation. It offers high reflectivity and high-performance insulation. It effectively blocks intense summer heat and retains interior warmth in winter, making it ideal for insulating doors, windows, roofs, and floors.

【Significant Cooling Effect】This aluminum foil insulation panel can reduce the perceived temperature by approximately 20 to 35% under direct sunlight.

This insulating material effectively reflects strong sunlight and radiant heat from the roof, helping to improve heating and cooling efficiency and reduce electricity bills (energy savings/improved thermal efficiency). 【Easy Installation, Versatile Applications】Ideal for car camping, this insulating/cooling panel is easily cut with a utility knife and installed with double-sided tape. A simple and practical DIY project. Widely used for insulating windows, verandas, ceilings, attics, car interiors, RVs, garages, and ventilation ducts.
