Aluminium butyl insulation mat as a roll, 50 cm x 400 cm, top price/top performance/top insulation. Often used in areas of HIFI, car insulation, car doors insulation, boot flaps, insulation, sliding doors insulation, etc. Details: – Components: butyl 1.9 mm and 0.1 mm aluminium layer and adhesive protective film – operating temperatures: -30° to +160° Celsius – the aluminium layer also has thermal insulation qualities – for easier unrolling, the aluminium layer stands over, thus avoiding the roll sticking together at the edge. Dimensions: 50 x 400 cm = per roll 2. m² (two square metres) (2 m²). Advantages: strong self-adhesive layer. Multiple layers are possible (simply stick on top of each other). Very flexible, therefore can be used almost anywhere and optimally in the angled area). Easy to use: cut to the desired size (e.g. with scissors or carpet knife also known as a cutter knife). Peel off the adhesive protective film, press on the desired place and youre done. A better price / performance / insulation ratio in the field of hifi, car etc. is hardly to be found.
