Double-layer thermal bubble foil made of high-quality aluminium with a durable bubble core — reflective insulation for floors, roofs, walls and vehicles Key benefits Effective thermal control: reflective aluminium surface and air-filled bubble core reduce heat transfer by reflecting solar radiation and slowing conductive heat flow. Year-round comfort: helps keep interiors cooler in summer and retains warmth in winter, reducing the need for active cooling and heating. Energy and cost savings: lowers heating and cooling demand by improving the building or vehicle envelope, supporting more efficient energy use. Noise reduction: the bubble core provides an additional barrier that helps dampen external sounds in garages, caravans and other spaces. Broad compatibility: designed for use on floors, roofs, walls and in vehicles such as delivery vans, motorhomes and caravans, as well as in garages, greenhouses and garden sheds. What makes it stand out Double thermal layer: two layers of aluminium-backed bubble film create a reflective, insulating barrier with a long-lasting bubble core. High-quality aluminium foil finish: reflects a large portion of incoming solar energy while providing a durable, moisture-resistant surface. Versatile application range: suitable for residential, commercial and vehicle installations without changing the core material or function. Features and function Material: high-quality aluminium foil bonded to a durable air-bubble core. Function: reflects sunlight and reduces heat transfer; retains interior heat in cold conditions; provides a secondary barrier against noise. Compatibility: can be applied on a wide range of substrates including wooden, metal and composite surfaces typically found in roofs, walls, floors and vehicle interiors. Practical use scenarios Roof lining for an attached garage: install under the roof sheathing to reflect daytime heat away, lowering peak temperatures in summer and keeping the space warmer in winter to reduce heating costs. Insulating a motorhome or caravan: line walls and ceiling panels with the foil to maintain a more stable interior temperature while parked or traveling, improving comfort and lowering HVAC use. Greenhouse climate control: use on the north wall or as a temporary cover to limit heat loss at night and reflect excess midday radiation, helping regulate internal temperatures and reduce energy needed for heating. Choosing this product Use when you need a lightweight, reflective insulating layer that works across multiple surfaces and environments. Ideal for projects where reflective thermal control, moisture resistance and additional sound dampening are required without major structural changes. Note: Product is the double thermal bubble aluminium foil with a durable bubble core, suitable for floors, roofs, walls, delivery vans, motorhomes, caravans, garages, greenhouses, sheds and similar applications.
