Tired of maintaining your wood cladding? Try Grinwood co-extrusion wall cladding!

Grinwood co-extrusion composite cladding was developed using the latest extrusion technologies to combine the durability of co-extrusion with the warmth and appearance of wood. An elegant and contemporary false open-joint profile enhances the facade while preserving its natural beauty and warmth. Colors with random nuances contribute to the realistic impression of an untreated, natural material.

For many individuals, the composite solution is ideal for all types of projects.

A stable cell profile with lugs

The Grinwood profile is stabilized by its underside, or backing.

There are lugs on the back of the boards of Grinwood composite cladding, which naturally create an air gap between the support and the siding. In vertical installations, they help install boards only on a wood or metal framework. A further benefit of Grinwood board coatings is that they are rot-proof and do not absorb moisture. Circulation of air is solely for ventilation of the support.


Grinwood cladding has a stylish false open-joint profile that is resolutely modern and attractive. Facades with embossed designs break the monotony and regularity of facades. This design ensures effective runoff of rainwater because of its trapezoidal shape. Furthermore, these composite panels replicate the open joints of wood cladding perfectly!

Two possible installation choices - vertical or horizontal - accentuate the perception of height or depth for exterior facades.
