Gypsum wood fibre board

When constructing a cladding panel there are many requirements that steer the choice of intrinsic materials. Among our first demands were; a strictly plane surface, dimensional stability, fire retardation, and acoustic characteristics. These demands effectively eliminate most traditional wood-based choices. A panel constructed of highly compressed gypsum and wood fibre incorporates the properties needed to meet fire prevention demands and offers good acoustic characteristics while at the same time offers us wood's versatility and aesthetic charm. The resultant panel is less sensitive to changes in temperature and humidity which in turn maintains the panels' lineage.

Solid wood edging

Prior to veneering, a solid wood edging is integrated around the panel, disguising the core material. when the veneer is then applied it covers the wooden edge and effectively gives the panel the appearance of being entirely of wood. This process contributes to the total strength of the panel making it more robust and ensures its dimensional characteristics.

Environmentally friendly

We employ entirely natural materials that damage neither health nor nature. The proportion of natural materials actually exceeds 98%. Since the gypsum wood fibre board does not contain any chemical binding agent, the material is very environmentally friendly.
