Glues, adhesives and assembly foams for wooden doors

Manufacturing frame profiles for door leaves

Contemporary door leaf frames are generally made of multilayered, glued particle boards. The middle layers are so-called blockboards or core boards, to which real wood veneers are bonded. The finished boards are then formed to the matching profiles and the corners are glued. We recommend using PVAc dispersions that are compliant with DIN EN 204 stress group D3, to ensure long-term stability and torsion-free products when using dowelled, slotted, tenon or counter profiles. For heavy-duty exterior wood doors, hardeners are added to the white glues, making them compliant with stress group D4 according to DIN EN 204. EPI systems can also be used when very long-lasting bonds are needed, but PUR glues actually provide the most durable results. The latter do not need additional hardeners, they are sold ready-for-use, are easy to use, and there are no pot life restrictions.

Manufacturing door leaf linings

Similar to frame profiles, particle boards such as core boards, chipboard and MDF are used for door leaf linings, depending on the intended door use. Exterior doors may also be lined with sandwich boards with an insulated core made of foam materials.

Manufacturing door frames

Nowadays, door frames are generally only made of particle boards. These are made to be and to stay torsion-free during their lifecycle. In general, PVAc dispersions (white glues), EPI systems and, increasingly, 1C PUR adhesives are used in the manufacturing process.

Gluing door leaves

The corners of door leaves are glued with the same types of adhesive as for frame profiles and panels. Common connections used in frame gluing are:

• finger jointing
• slotted and tenon joints
• dowels

Installing wooden doors

Two-component PUR foams are generally used to install door frames. These foams have a high load-bearing capacity and very short setting times, so that braces do not need to be used for a long time.

Single-component PUR foams and other assembly tools can be used for connecting block jambs, in which case no braces are needed for stabilizing.
