Spruce HVAC Beams Non-viewing Nsi 140x140x5000 mm
Available at the branch
Spruce KVH Prisms Non-view Nsi 140x140x5000 mm are four-sided planed prisms dried to 15% (+-3) with a shrunk edge.
KVH prisms are made of solid spruce wood and are not impregnated. The structural prisms are lightweight, dimensionally and dimensionally stable. No chemical treatment is necessary - wood-destroying fungi and insects are destroyed when drying.
KVH prisms 140x140 and their use
- Load-bearing walls of post-and-beam buildings,
- Beam/joist ceilings with soffit,
- Roof trusses,
- Garden structures (pergolas, carports, gazebos).

Detailed Description
What is a KVH prism
KVH prism is a quality construction material made from dried spruce lumber. The manufacturing process involves drying to 15% moisture content with a tolerance of 3%, then planing to the exact dimension and removing defects.
The pieces are joined using a tooth (zinc) joint and glue. The KVH prism can reach 13 m with a strength class C 24 (24 MPa bending strength).
What is the difference between KVH NSi and KVH Si
KVH NSi - Non-visible quality
- Blueing and minor defects possible, without affecting mechanical properties.
- Suitable for constructions where aesthetic appearance is not crucial.
KVH Si - Visual quality
- Used for visible structures such as ceiling beams, trusses, pergolas or gazebos.
What are the advantages and disadvantages of KVH prism
+ dimensional stability and high strength,
+ drying is worth the lower weight,
+ no need for treatment (high temperature during drying eliminated wood-destroying fungi and insects),
+ the zinc "tooth" joint can connect the prism up to 13 m long,
+ planed and chamfered edges,
- higher price
How we store KVH prisms
KVH prisms are stored horizontally in well-ventilated areas to prevent possible scorching and subsequent changes in wood properties such as discolouration, warping and cracking.
