Efficient implementation of energy saving regulations

Sika prepares individual cost analyses for window manufacturers and window installers.

In collaboration with Sika window engineers, PVC window system suppliers aluplast, profine, REHAU and VEKA have developed and tested the especially economical rebate bonding technique for selected systems. Their engineers chose Sikasil ® WT-480 adhesive for this application. This adhesive is distinguished by its outstanding UV resistance, excellent adhesion, profile, high mechanical strength, and optimised application properties.

Rebate bonding has already proven its merits in more than six million windows. The basis for the comprehensive test regime is the new RAL standard. With rebate bonding, the system fits. Chemical compatibility of the insulating glass secondary sealant with the adhesive is a prerequisite. In addition to a comprehensive range of bondable profiles, window fabricators can now choose from a wide spectrum of bondable glass. Renowned insulating glass manufacturers collaborate with Sika and employ the compatible, mercury-free SikaGlaze IG-50 sealant. Alternative insulating glass sealants are tested for potential incompatibility with Sika adhesives in the Fenestration Competence Centre in Switzerland.
