Groke aluminium front doors stand out from the rest

Many other manufacturers use bought-in profile systems. Not Groke: We developed our own profile system and have continually optimised it right down to the last detail.

An installation depth of 90 mm and material thicknesses of up to 3 mm make Groke doors stable and robust. The heavyweight construction and safety features already included in the standard equipment offer reassuring protection. A stable joint between the frame and sill facilitates installation and ensures that the structure will be extremely resilient and durable.

As a standard feature, three sealing layers along the entire edge of the door provide a high level of wind and weather proofing. Because only a tightly sealed door offers proper thermal and sound insulation.
