Product description optimized for strong conversion Product type and value A type of quality aluminized thermal insulation material designed for long service life. It is reusable and recyclable. Construction and performance Doublelayer aluminium foil bubble heat insulation film made from reflective aluminium film and polyethylene foam. The surface aluminium film directly reflects rays and heat, while the bottom aluminium film blocks part of the heat. Doublelayer protection provides effective heat insulation and preservation. Key benefits Improves thermal efficiency by reflecting heat and reducing heat transfer Reduces strain on heating and cooling systems Helps keep interiors warmer in winter and cooler in summer Moisture resistant with heat reflection properties Blocks heat transfer through iron, concrete, wood and other materials Usage and compatibility Suitable for use next to the heater or fireplace, rooftops, residences, factory plants, car roofs, sheds, balconies, farms, sun rooms, color tile rooms, roofs, walls, mobile homes, and more. Practical impact Energy saving throughout the year with potential reduction in utility bills Summer: sun protection, heat insulation, reduced air conditioning needs Winter: heat preservation, heating savings, noticeable effect Size, material, and performance attributes Doublelayer structure with reflective aluminium film and polyethylene foam Designed for longterm use, reuse, and recyclability Strong insulation, moistureproof, and heat reflection capabilities
