Panel types
KLH® solid timber panels are offered in 3 standard qualities. Upon request special surfaces and panel built-ups are possible, depending on the availability of the raw lamellas and technical feasibility. Special structures are possible upon request.
By using double layers, the board’s longitudinal and transverse rigidity can be increased in a targeted manner. Changes to the board structure can be used to increase its fire resistance in order to meet special project requirements.

Surfaces &
Qualitydefinition
As a standard, we produce KLH® solid wood panels in spruce and in three different surface qualities, which can be combined as required. This applies without restriction for all the panel types shown previously.
Surfaces treatment and special surfaces
Both the industrial visible quality and the domestic visible quality panels are fully sanded. We also offer domestic visible quality surfaces in a brushed version. Should you require UV protection, varnished elements or any other surface treatment, please contact us. The same applies to surfaces in other types of wood, which we can offer depending on customer requirements and the availability of raw materials.
Overview of the individual surfaces
| Domestic Visible (DVQ) | Industrial Visible (IVQ) | Non Visible (NVQ) | |
|---|---|---|---|
| Application Area | Visible components without restrictions used in residential constructions. | Visible components with with moderate restrictions, not recommendet for residential constructions. | Pure structural components with subsequent panelling. |
| Demand towards Surface | high demand | medium demand | no demand |
| Production-Related References | chamfer on TL panels | chamfer on TL panels | no chamfer |
| Surface Finishing In-Plant | fully sanded (one- or double sided) also one side brushed | fully sanded (one- or double sided) | planed |
| Surface Treatment In-Plant | on request | on request | not possible |
Minimum requirements
THE MINIMUM REQUIREMENTS FOR EACH SURFACE DESCRIBED REFER TO THE TIME OF DELIVERY.
FOR NARROW SIDES AND CNC-TREATED SURFACES, THE CRITERIA FOR NON-VISIBLE SURFACES APPLY.

| Blue stain and red tinge | slight discolouration permissible (≤ 3 %) | slight discolouration permissible (≤ 5 %) | no restrictions | |
| Branches, tightly intergrown | permissible | permissible | no restrictions | |
| Branches, black | permissible ≤ 25 mm Ø | permissible ≤ 35 mm Ø | no restrictions | |

| Range of validity | The given surface qualities at delivery only include the non-machined top layer but not the edges of the elements. The edges as well as machined surfaces are subject to our non-visual surface criteria. |
|||
| Crack formation | Like all solid wood products, the above stated qualities are subject to crack and joint formation as a result of drying to their future compensation moisture balance when installed due to the product characteristics. This cannot be prevented. | |||
