Sika has the complete product range available for silicone insulating glass sealants even in grey color. Insulating Glass solutions are suitable for gas retention for more than 30 years.

Insulating Glass including Thermal Insulation

The facades are mainly responsible for the energy balance of a building. The excellent thermal insulating effect of bonded double or triple glazed units with coated glass can save much of the energy otherwise consumed for heating or cooling.

The air or noble gas trapped between the bonded panes is a poor heat conductor and therefore forms a good insulating layer between the outdoor and indoor air. To seal the insulating glass units requires not only high quality products but also a uniformly high quality of workmanship.


"Sika was the first to introduce an IG sealant that has a mechanical strength that is superior to previous insulating glass adhesives. With the Sikasil® IG-25 HM Plus, Sika sets a new industry standard. "
