A really smart idea. With a 90 degree folding door, a wide entrance is guaranteed and the room is optimally heat-insulated by pre-folding. The flexible door nestles close to the B-pillar. The fastening is done at the top with snap fasteners. A strap fastened with Velcro ensures a tight seal. With detailed assembly instructions. Material: A sandwich construction with a friendly exterior colour and 8mm insulation core. Light grey polyester velour inside, aluminium coloured polyester film outside.
