Silka, from the team behind Apeer doors, has trademarked Thermafill for its window and door range.
The insulation creates a thermal break to enhance the performance of the window and door frames.
“Silka windows have been designed to feature extra wide Thermafill insulated chambers that offer side-to-side insulation,” said sales director Andy Jones, “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.”
