External insulation mat for motorhomes – keeps the heat inside the vehicle and the cold outside. The mat can be rolled down along the A-pillars to the bottom edge of the windscreen, so that nothing obstructs the view outside when the mat is installed. It is also divided into two parts, so that only the upper part can be installed in summer, for example. The floor-length mat can be optimally secured using the attached fastening strip and a special tensioning solution, while the two-part design ensures easy handling. At the same time, it insulates the ventilation slots in the bonnet, the doors and the openings of the clutch linkage. Thanks to its good cold elasticity properties, the mat fits snugly to the vehicle and does not allow cold air to penetrate. The external insulation prevents cold bridges and there is hardly any condensation on the windows inside.
