SILKA trademarks Thermafill™

In a bold move, SILKA has trademarked Thermafill™ for its revolutionary window and door range offering both top levels of energy efficiency as well as incredible style. SILKA is designed by the team behind Apeer doors and has used its immense knowledge and technical expertise to create this ahead-of-the-curve glazing system.  

Thermafill™ is one of the clever technical additions that means SILKA can deliver such high levels of thermal performance. The insulation creates a highly effective thermal break to massively enhance the performance of the window and door frames.

While last year’s building regulations, requiring a big increase in energy performance, have caused a headache for many aluminium window and door system companies, SILKA was designed to exceed the new regulations.  

“The revolutionary SILKA windows have been designed to feature extra wide Thermafill™ insulated chambers that offer side-to-side insulation,” says Andy Jones, Sales Director for SILKA. “Our experience tells us that many people are looking for windows and doors to exceed current building regulations, especially when it’s their forever homes. People planning extensions, whole house refurbishments and self-builds are demanding higher rates of energy efficiency, which can be tricky with standard aluminium frames. That’s why we have designed SILKA to offer top thermal efficiency which we believe is the key to future-proofing this stunning-looking new window and door system.”
