Size: 1 x 5M (3.2 x 16.4 FT) Product overview performance double thermal bubble roll made from reflective aluminum foil with a durable bubble core. Designed to reflect solar radiation, reduce heat transfer, and provide thermal and acoustic insulation for a wide range of spaces and vehicles. Key benefits Keeps interiors cooler in summer by reflecting sunlight and reducing heat gain. Helps retain heat in winter by limiting heat loss, reducing the demand on heating systems. Lowers energy use and running costs through improved thermal performance. Adds a layer of sound attenuation to reduce external noise in garages, vans, and outbuildings. Lightweight, flexible, and easy to cut and fit to irregular surfaces. Features and attributes Size: 1 x 5M (3.2 x 16.4 FT), suitable for covering large areas or multiple small projects. Material: Doublesided aluminum foil facing with a durable bubble core for insulation and structural resilience. Function: Reflects radiant heat, provides thermal barrier, and offers additional acoustic damping. Performance: Effective at reducing heat transfer through roofs, walls, and floors when installed as an insulating layer or reflector panel. Compatibility: Suitable for floors, roofs, walls, vans, campers, caravans, garages, greenhouses, sheds, boats, and similar spaces. Practical applications and scenarios Camper or van conversion: Line the interior walls and ceiling to reduce daytime heat buildup, retain warmth during cold nights, and lower fuel or battery consumption for heating and cooling. Garage or workshop insulation: Install on rafters or wall surfaces to moderate temperature swings, improve comfort while working, and reduce noise from outside. Roof or greenhouse lining: Apply under roof panels or between framing to reflect excess solar heat away in summer and retain warmth in cooler periods, helping to stabilize internal temperatures. Installation notes The roll can be cut to size with common tools and fixed in place using tape, staples, or adhesive as appropriate for the application. For results, install with the reflective surface facing the direction of incoming radiant heat when used as a heat barrier, or facing an internal cavity when used as a radiator reflector. What makes this product stand out Combines reflective aluminum and bubblecore insulation in a single lightweight material for versatile thermal control. Suitable for both seasonal cooling and heating support, making it a practical choice for yearround use. Multipurpose use across vehicles, buildings, and small structures where space, weight, and ease of installation matter. Packaged dimensions and handling Delivered as a 1 x 5M roll that can be trimmed to fit specific layouts. Store flat or standing to avoid creasing prior to installation.
