If you’re looking at glazing for your home renovation, extension or self-build project, it’s likely energy efficiency will be high on your list of must-haves when it comes to windows and doors.

There are three ways we can reduce what we spend on energy: insulating our homes properly, generating energy through additions such as solar PV panels, and rethinking our usage in day-to-day life. Taking a ‘fabric first’ approach means getting the insulation spot on – and that’s where our journey to create Thermafill began.

With the rising cost of living, it’s essential to invest in technologies that not only enhance our quality of life, but also help reduce energy bills. SILKA offers top energy performance through its range of glazing products thanks to our innovative technology, which we’ve called Thermafill.

Thermafill is a game-changer in the quest for energy efficiency in glazing, and it can significantly help to lower your energy bills. Here’s why we love it, and you will too.


Thermafill®: The key to energy efficiency

At the heart of SILKA’s energy efficient frame technology lies Thermafill, a pioneering product that revolutionises the thermal performance of our windows, doors and rooflights. With its edge-to-edge insulation, Thermafill creates a unique thermal barrier, ensuring superior levels of energy efficiency and soundproofing for your home, day in and day out. By insulating the chambers within the outer frame and sash profiles, Thermafill creates a complete thermal break, effectively insulating your home.

The power of triple glazing combined with Thermafill®

The benefits of Thermafill as a standalone technology speak for themselves, but when combined with triple glazing, its effectiveness creates top level thermal performance. This winning combination forms the SILKA futureproofed aluminium glazing suite, delivering unparalleled energy efficiency, warmth and sustainability for your home. Triple glazing ensures the insulated glass unit – being the largest component of your windows, doors or rooflights – boasts top thermal performance values, guaranteeing exceptional energy efficiency throughout the entire product.
