Holz

DERALAM HOLZ is a laminate (HPL) with a surface of ready-to-use real wood. By using reconstituted veneers as well by the final coating we can assure a nearly constant image of the veneer.

For the production of reconstituted veneers, peeled veneers from poplar-, koto- and ayous wood are partly dyed, rejoined together in layers and pressed to a block from which the reconstituted veneers are sliced. By putting together different peeled veneers and using special pressings the most popular, even exotic species of timber can be reproduced. Valuable resources are saved this way, without having to give up special and extravagant decors. We press these reconstituted veneers in the well-known production process to laminates. The surface is finally lacquered or melamine coated, inspected and covered with a protective film.

* The bending radii indicated in the table represent radii, which can be achieved under normal conditions where constant force is distributed uniformly over the entire surface. Factors as the degree of moisture in the laminate, temperature, as well as the method of bending have an effect on the radii and can lead to deviations in the results. Widths of the test stripes: 50 mm

Holz

Natural components:

Although it is a reconstituted veneer small variations of the grain resp. of the colour are unavoidable and show only the natural characteristics of wood.

hygroscopicity:

The material tends to adapt the moisture of the wood to the environmental moisture, thus wood has a small dimensional stability (expansion resp. shrinkage)

Light Fastness:

Influenced by Strong UV-light all different types of wood – even reconstituted woods - change their colour. Therefore, we recommend using DERALAM HOLZ for interior applications that are not exposed to sunlight directly.

Protective film

DERALAM sheets are covered with a protective foil. It is recommended to leave this foil on the surface of the laminates during processing. Nevertheless, colour, colour uniformity and other quality checks ofthe sheets must be carried out beforehand.

Important:

The surface, which is protected with a removable foil, should not be exposed to light for long periods of time. This could cause problems in removing the protective foil. (Use a cover sheet)! The protective foil is not diffusion tight towards liquids.

Processing

DERALAM HOLZ products can be sawn, drilled, milled etc. like all standard high pressure laminates. The sheets can be bonded to standard base materials with conventional glues or adhesives.

CARE/CLEANING

To clean the surface use a soft non-pilling cloth and a mild cleaning agent that must not contain any abrasive substances. Do not use any solvent.

APPLICATION

DERALAM HOLZ laminates are recommended for interior vertical applications in which the products are hardly exposed to harmful environmental conditions such as strong UV light or extreme changes in temperature.

BALANCING MATERIAL

Stresses always occur between two different types of material bonded together. Consequently, a base material should be surfaced on each side with materials, which are subject to the same dimensional changes resulting from variations in temperature and influence of humidity. This is particularly important if the finished sheet is to be self-supporting and not directly retained by a rigid structure. It is necessary to condition all materials in the same climatic conditions for at least 48 hours.

Holz

The larger the area to be covered, the more important is the right choice of the balancing material, symmetrical structure, density and rigidity of the base material.

According to our experience base material with a thickness of 13 mmis critical with regard to the flatness of the compound element. Generally factors like for example stiffness and symmetric structure of the base material, the even application of the adhesive and the pressing temperature as well as the size and degree of fixing of the object do have a disproportionate high influence. Therefore, we recommend using for compound elements with base material  13 mm the same laminate as balancing material.

Best results are obtained by using the same type of laminate from the same manufacturer on both sides. Both must always be bonded simultaneously from both sides to the base material in the same direction of grain or grinding respectively (never at right angles to each other).

In order to keep costs low use second choice laminates of the same type as balancing material or special balancing material without any demand on the surface (Blind veneer). The use of other kinds of material as balancing material is not recommended – even when physical properties are as similar as possible to those of DERALAM HOLZ laminates – as the results can never be predicted with certainty.
