The beauty of bonded windows is the ability to reduce the sash width profile cross section. Using Sikasil® adhesives eliminates the steel reinforcement, which in turn reduces the energy transfer though the sash by approximately 20%. The slimmer sash allows more light into the living space and adds to the occupants ‘Well Being’. Other advantages of using adhesives to bond windows include; an elimination in costly call outs to fix 'catching' window sashes, burglary resistance and lower  manufacturing costs.
