System consists of:
- VWM window buck 80 x 80
Window buck 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.
- VWM window buck 140 x 90
For projections up to 140 mm. Suitable for windows with larger installation depths or windows with roller shutter add-on systems.
- VWM window buck 160 x 110; 180 x 110 and 200 x 110
Allows particularly large projections 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.
- VWM construction adhesive
High-quality, neutral and permanently elastic 1C special adhesive and sealant for bonding and sealing VWM exterior insulation foam modules. Good initial adhesion and easy processing. Excellent adhesion to common surfaces such as
- Concrete
- Autoclaved aerated concrete
- Clay brick and calcium silicate block
- Wood
Porous surfaces may require priming before applying.
Ensure adhesion surfaces are dry, suitable, clean, dust- and grease-free when applying.
Observe the application instructions.
Sets each consist of VWM window buck, VWM insulation block and VWM construction adhesive - delivered on a standard Euro pallet
- 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.
- Technical data and other product documentation can be found at www.wuerth.de
