Size: 1x12m (39 in X 39 Ft) Overview A selfadhesive thermal insulation film with doublesided metallized aluminum facing. Designed to reflect radiant heat, reduce temperature swing, and provide additional sound damping when applied to walls, ceilings, and floors. Key benefits Improved thermal comfort: Reflects radiant heat to help keep interiors cooler in summer and warmer in winter, reducing the load on heating and cooling systems. Energy and cost savings: By lowering HVAC workload, the film can help reduce utility bills over the year. Sound reduction: Adds a layer that helps dampen airborne noise when installed in walls, ceilings, or floors. Durable and weather resistant: Metallized aluminum facing resists moisture and humidity and is suitable for indoor and outdoor use. The product is described as 100% waterproof. Airtight barrier: Helps limit air, dust, and pollutant infiltration when applied over gaps or seams. Main features Size: 1x12m (39 in X 39 Ft) for coverage of large areas with a single roll. Material: Doublesided metallized aluminum barrier for reflectivity of radiant heat. Selfadhesive backing: Preapplied adhesive makes installation straightforward and maintenance; the film remains sticky to reduce the risk of detachment. Easy to cut and fit: Can be trimmed to shape with a hobby knife or scissors for precise installation. Long service life: Built for durability in garages, attics, sheds, barns, warehouses, and similar spaces. Installation and performance notes Surface prep: Apply to clean, dry surfaces for adhesion. Cutting and fitting: Trim with a hobby knife or scissors; overlap seams as needed to improve coverage. Maintenance: No special maintenance required after installation. Practical use scenarios Attic insulation: Install under roof rafters or over existing insulation to reflect radiant heat away from living spaces and reduce attic temperatures in summer. Garage or workshop: Line walls and ceilings to reduce heat gain in summer and slow heat loss in winter, improving comfort and protecting tools and equipment. Outbuildings and warehouses: Use as a radiant barrier in sheds, barns, or storage areas where humidity may be present; the metallized foil resists moisture and dust penetration. What makes it stand out Combines a reflectivity doublesided aluminum barrier with a convenient selfadhesive backing for quick installation. Suitable for a wide range of indoor and outdoor applications and surfaces that need radiant heat control and added sound damping. Large roll size simplifies coverage of larger areas without frequent joins. Specifications summary Roll size: 1x12m (39 in X 39 Ft) Facing: Doublesided metallized aluminum Backing: Selfadhesive, peelandstick application Properties: Reflective, moisture resistant, sound damping, easy to cut This thermal insulation film provides a practical way to control radiant heat, reduce energy use, and add an airtight, moistureresistant layer in garages, attics, sheds, barns, warehouses, and residential walls, ceilings, and floors.
