Double thermal bubble foil made from high-quality aluminum foil with a durable bubble core. Reflective, insulating barrier designed for a wide range of applications including floors, roofs, walls, vans, motorhomes, caravans, garages, greenhouses, sheds and more. Key benefits Effective thermal reflection: the aluminum surface reflects solar radiation to help keep interior spaces cooler in summer. Year‑round temperature control: the foil helps retain heat in winter by keeping cold out and warmth in, supporting more stable indoor temperatures. Energy efficiency: by reducing heat gain in summer and heat loss in winter, it helps lower heating and cooling demands and supports cost savings. Noise reduction: the layered construction also provides a measure of sound dampening from outdoor noise, increasing comfort in garages, vehicles or living spaces. What makes it stand out Double thermal bubble construction: a durable bubble core sandwiched between aluminum layers for combined reflective and insulating performance. High-quality aluminum facing: provides long-lasting reflectivity and corrosion resistance suitable for indoor and sheltered outdoor use. Versatile compatibility: suitable for installation on multiple surfaces—floors, roofs, walls—and in vehicle and building applications. Practical applications and use scenarios Campervan or motorhome roof and wall lining: Reflects daytime heat away and helps retain warmth overnight, improving comfort on trips and reducing the load on onboard climate systems. Garage or workshop insulation: Fits behind panels or on doors to reduce heat loss and dampen external noise, improving energy efficiency and usability of the space. Greenhouse or shed temperature control: Helps moderate internal temperatures by reflecting excess solar heat in summer and reducing heat loss in cooler weather.
