Acoustic blanks

Acoustic blanks are not suitable for veneering due to their special core.


If additional edges are attached, the moisture content of the wood should be identical to that of the door blank. Gluing D4 according to EN 204.


We recommend using the same materials and material thicknesses for further processing.

Double up

Single-sided extensions must be designed and fastened in such a way that they can follow the changing climate influences without affecting the door body. This means flexible, sliding storage using construction adhesive or mechanical fastening.


Like all veneered wooden surfaces, door blanks must be soaked before processing and subjected to a visual inspection after approx. 1 hour. Damaged or faulty blanks may only be processed after factory consultation.


Front door blanks must be stored in an ambient climate that corresponds to the wood equilibrium moisture content of an installed front door leaf of 12% +/- 1%. Storage must be on a flat, level surface, protected from soil moisture.


For outdoor use, AW gluing in accordance with DIN 68 705 T2 must be used. Please note the relevant guidelines of the glue manufacturer

Light cutouts

When making light cutouts, it is important to ensure that no moisture can penetrate the door leaf. Glass retaining strips in particular must be designed to be tight. This also applies to mitres in the glazing bead frames.


With milled glazing beads, the top layer acts as a flush glazing bead. It is important to ensure that no residue of the underlying layer of sticks remains.

Surface treatment

Front door blanks, CNC machined door leaves (also in conjunction with a kit) must be watered before surface treatment and subjected to a visual inspection after 1 hour. After drying, the workpieces must be sanded. Damaged blanks and door leaves may not be processed further without consulting the factory.


When treating the surface, the paint manufacturer's instructions must be followed.


A minimum dry layer thickness of 100 mµ must be maintained for glazes and 120 mµ for opaque coatings.


The surface coating must be evenly applied at every point on the door leaf.


Oiled, primed or untreated door leaves are excluded from any warranty.

Press pressure

The pressing pressure when veneering is 0.3 to 0.5 N/mm².

Pressing temperature

Max. 105°C. Special case for front door blanks with aluminum vapor barrier:
Always keep the pressing temperature as low as possible to avoid creating steam pressure in the glue joint. Due to the aluminum barrier layer, moisture compensation in the blank is not possible. The guidelines of the glue manufacturer must be observed.

Sawing and milling

All variants can be processed with carbide-tipped saw blades/milling cutters on common woodworking machines. For HPL door blanks, please use a special tooth geometry as recommended by your tool manufacturer.

When shortening the blanks, the technical information and drawings on the associated technical product flyer must be taken into account.


The position of the flat steel stabilizer, as well as the lock and hinge sides, are marked with a product sticker on the lower narrow side of the blank.
