Fire-Rated Sealing

Many casualties have been reported in serious fire situations, not only because of fire but also smoke inhalation. The integrity of the joints is vital and provides the fire services with time to rescue people. Sika offers 4 hours fire-rated sealants both for vertical joints in facades and for horizontal floor joints between the facade and the floor slabs.

Glass-to-Glass Construction

For glass-to-glass applications (fin glazing, total vision glazing) Sika offers various Sikasil silicone sealants, from low modulus sealant to high modulus adhesive.

Glass Wall Grouting

Depending on the climatic conditions Sika EPDM membranes and/or both wet sealants (Sikaflex PU or Sikasil silicone) can be used for movement/connection joints and perimeter sealing around curtain wall facades and window frames. The SikaMembran System consists of various types of membranes with optimized levels of vapour diffusion for the use in all climatic conditions.

Insulating Glass

The facades are mainly responsible for the energy balance of a building. The excellent thermal insulating properties of bonded double- or triple-glazed units with coated glass - sealed by dual-seal technology - can save much of the energy otherwise used for heating or cooling systems.

The secondary seal holds the glass panes tightly together and prevent excessive movement in the IG edge seal. High-modulus adhesives are necessary for a long service life of the IG units. Only silicones are approved as a secondary seal in structurally glazed facades. For windows and capped curtain wall facades PU are a good value-for-money alternative but it should be ensured that there are no specific requirements for the project such as high temperature spandrel panels, where temperatures can reach 100 ºC.

The primary butyl seal is the main barrier against ingress of water and air humidity and loss of inert gases, e.g. Argon. Therefore a durable premium-quality butyl is a must in both air- and argon-filled IG units. For gas filled units high performance secondary silicone sealants are required to provide added protection for the primary butyl seal.

Panel Bonding

The SikaTack-Panel System consists of an adhesive and a prefixing tape, which holds the panel during the full vulcanisation of the glue. Bonding of panels, instead of screwing, prevents high stress in the panels and galvanic corrosion. It gives the architect a great freedom of design. This system can be used for direct on-site and factory bonding for fast on-site installation.

Panel Reinforcing

Big panels become fashionable in façades. In order to save weight the panels get thinner and thinner. To stabilise against flattering the panels are stiffened with a metal or plastic profile bonded to the back side.

Structural Glazing

Sika’s structural glazing adhesive sealants Sikasil SG have shown their excellent resistance UV and weatherability in major projects around the globe. In façade constructions many different materials come into contact with each other, Sika provides a complete support package to ensure compatibility of all products for façade manufacturers.

Water / Vapour Proofing

Depending on the climatic conditions Sika EPDM membranes and/or both wet sealants (Sikaflex PU or Sikasil silicone) can be used for movement/connection joints and perimeter sealing around curtain wall facades and window frames. The SikaMembran System consists of various types of membranes with optimized levels of vapour diffusion for the use in all climatic conditions.

Weather Sealing

As with Structural glazing systems many sealants and adhesives which come into contact with each other and many other materials will require high-quality products, which are compatible with all substrates and ancillary products. Therefore Sika supplies suitable professional sealants for all kinds of sealing applications, including non-staining sealant for natural stone facades.
