One-side self-adhesive sealing tapes for glazing of windows made of wood
VITO glazing tapes are made of a closed cell PET-Foam equipped on one side with a special pressure sensitive glue favorable to an intact environment. The elasticity of the VITO glazing tapes compensates the movements caused by wind load stressing as well as by changes in temperature and humidity. These may occur at different speed and may overlap.
Suitably applied and in conjunction with commercially available elastic sealing materials VITO glazing tapes ensure closed glazing joints which show efficient weathering resistance. Produced in the mentioned way, the durably elastic glazing joint performs its function for many years.
A positive effect obtainable through the use of glazing tapes is the better isolation against transmission of noise. Our glazing tapes are free from softening agents. They can be used within a temperature range extending from −80 °C up to 50 °C. Compatibility with commercially available elastic sealing materials is given. High adhesive strength and shearing strength guarantee a stable adhesive cohesion power. Only in case of uneven and porous grounds, a preliminary paint (primer) is recommendable in order to achieve a good adherence. But normally our glazing tapes do not need any preliminary paint. The glazing joint must be dry and exempt from any separating agents and dust.
The recommended temperature of application is between 2 °C and 30 °C.
According to instructions given by the Institut für Fenstertechnik e.V. in Rosenheim and the Glasfachschule in Hadamar the glazing tapes shall be inserted not only towards the outer side also towards the inner side of the room (please refer to the diagram).
This mode of application serves the better application of elastic sealing materials. Up to stress group 4 it is recommendable to use VITOGLAS 12O and VITO GLASERFIX 111. From stress group 5 the use of a special glazing tape is necessary. In this case we recommend VITOGLAS 110.
Glazing tapes made of polyethylene foam may not be exposed to direct insolation, because the upper layer at the surface (about 1 mm deep) would be destroyed by the high ultraviolet load. VITO sealing and glazing tapes are available in different versions.
