System consists of:

Mounting bracket VWM 80 x 80:

Mounting bracket format adapted to popular profile and window systems for characteristic application when window is directly mounted in the transition area between the wall shell and insulation/ETICS.

Mounting bracket VWM 140 x 90:

For overhangs up to 140 mm. Suitable for windows with larger installation depths or windows with roller shutter add-on systems.

Mounting bracket VWM 160 x 110; 180 x 110 and 200 x 110:

Allows particularly large overhangs of 160 mm, 180 mm or 200 mm. Suitable for window installation in front of the supporting wall with 2-shell construction and faced brickwork or if particularly high insulation thicknesses are to be implemented.

Assembly adhesive VWM:

High-quality, neutral and permanently elastic 1C special adhesive and sealant for bonding and sealing the pre-wall mounting system VWM. Good initial adhesion and easy application. Excellent adhesion to common surfaces like

  • Concrete

  • Aerated concrete

  • Clay brick and sand-lime brick

  • Wood

Priming beforehand may be required for porous surfaces.

Ensure adhesion surfaces are dry, suitable, clean, dust and grease-free when applying.

Observe the application instructions.

  • Observe the RAL guidelines on assembly and planning of windows and house doors when planning and assembling (art. no. 5995 000 000).

  • When mounting, special case 1 or, if applicable, special case 2 are to be taken into account, if there are special requirements.

  • It is important to check that installation has been performed correctly for the specific construction conditions (e.g. weight of window casement, surface properties). When planning and selecting suitable fasteners, their properties (e.g. application surface, edge spacings, loads) need to be taken into account.

  • The pre-wall mounting system VWM is not suitable for the attachment of accident-proof glazing in accordance with the German technical regulations for safety glazing (TRAV) or DIN 18008-4.

  • Instructions for processing can be found in the processing guidelines/mounting instructions.
