VITO Glazingmount


Spacer and vibration absorbing system for a large variety of applications

VITO Glazingmount 400 consists of a high-density double-side self-adhesive polyurethane foam. This quality is equipped with a high-performance acrylate-based adhesive. This product is especially designed – as spacer tape – for applications in the assembly and mounting of structural glazing systems with entire glass façades.

VITO Glazingmount 400 has already been successfully applied for the construction of façades, halls, winter gardens, the fitting of windows and as spacer and vibration absorbing system for a large variety of applications.

The use of high-grade pure acrylic adhesive ensures excellent shear resistance on surfaces consisting of glass, steel and anodized aluminium. The tape is characterized by an excellent resistance against weathering and UV radiations.

Product benefits

  • The high-performance adhesive has very good shear adhesion on glass, steel and anodized aluminium. By appropriate application the double-side spacer tape keeps the involved components in position, until the silicone is hardened.
  • The black adhesive surfaces effect a uniform appearance of the glazing.
  • The low thermal conductivity of the PU foam contributes its part to the thermal insulation and reduces fogging due to condensation water.
  • VITO Glazingmount 400 is compatible with all tested silicones. The certificates of the silicone producers are available.
  • VITO Glazingmount 400 is successfully tested as distance tape for structural glazing by the Institut für Fenstertechnik in Rosenheim, Germany (ift test report 507 20370 from 20.08.1998
