Our product range includes products known as KVH prisms, which are made from dried and planed spruce wood. The average moisture content of the wood in these prisms is kept at 15% (+-3%).

We offer you exclusively NSi non-glossy quality, which differs from the glance quality by appearance imperfections. If you care about appearance, we do not recommend placing KVH prisms in a visible place. The shortcomings of the non-visual KVH prisms are listed below.

The edges of these prisms are carefully beveled to ensure their safety during handling and installation. The rounded edges also contribute to the aesthetic appearance of the structure.

HVAC prisms over 5m are joined by zinc plating. In exceptional cases, galvanising can also be used for prisms less than 5m in length.

Galvanizing joints are made by means of special milled teeth, called zinc joints, into which glue is applied. In this way, the individual pieces of the prisms are firmly and reliably joined. KVH prisms, which offer excellent strength, stability and durability. They are ideal for a wide range of building projects and structures. When using them, you can be assured of reliability and longevity.
