With an installation depth of 82.5 mm and modern five-chamber technology, the new S 9000 front door offers outstanding heat insulation. Also impressive is the new front door's stability. This is accomplished by the large chamber for stiffening elements, shaped steel reinforcements and matching corner reinforcements as well as the firm bond in the area of the ground threshold produced by the vinyl and aluminium parts engaging on two planes.
The S 9000 front door also scores with its weatherboard system solution that upgrades the door elements both functionally and visually. It ensures maximum protection against driving rain and effective sealing by means of insulation profiles at a number of levels in the area of the ground threshold.
