Structural Glazing / Insulating Glass / Weather Sealants

STRUCTURAL SEALANT GLAZING

Structural glazing modules are subject to extremely high stresses. They must accommodate wind and snow loads as well as thermal expansion. Furthermore they permanently transfer the forces to the support structure, while also withstanding weathering over many years. High-modulus Sikasil SG silicone adhesive sealants offer the best properties for this purpose.

SYSTEM BENEFITS

  • Strong but flexible fixation of glass units
  • Attractive appearance without visible frames
  • No shading of glass edges, no thermal stress
  • Most energy efficient facade technology

INSULATING GLAZING

In insulating glazing, double or triple glazing alike, it is particularly important that no water vapor should penetrate into the space between the panes and, in case of noble gas-filled units, the gas losses should be reduced to a minimum. Thus, a double-sealed edge seal system is state of the art. Sika offers a complete product range for IG edge sealing including primary and secondary sealants, suitable for gas retention of 30+ years.

WEATHER SEALING

The quality and optical appearance of a curtain wall are critically dependent on appropriate weather sealing. The facade elements are ultimately subject to extreme movements due to temperature changes, moisture (in the case of concrete), shrinkage of construction materials (wood, concrete), sound, wind and vibrations, which may affect the joints and adjacent elements. Natural stone elements request compatible non-staining solutions.
