Thermafill® insulated frame technology is the answer for energy efficient windows. Created exclusively by SILKA specialists, Thermafill® redefines energy saving performance for aluminium windows.
Futureproof your home with energy efficient windows by SILKA. Our triple glazed aluminium window and door collection has been specially engineered to offer top energy efficiency to keep your home warmer in the winter and cooler in the summer, as well as reducing the carbon impact of your house.
When it comes to the best of all worlds, aluminium is the best option on the market for energy efficient windows. Slimmer frames and sleek profiles deliver sensational styling, and the strength of aluminium means your window frames can be wider and higher, without any compromise on performance.
For energy efficient windows, you need Thermafill®. It’s one of the most advanced developments in aluminium window technology and works by insulating the chambers inside the aluminium profiles. Thermafill® insulation delivers incredible thermal efficiency and is only available on SILKA windows and doors.
After rigorous testing from third parties, SILKA Windows achieved an incredible U-Value of just 0.8 W/m2K. As one of the lowest values on the market, this means that SILKA energy efficient windows are fit for the future, even with the tightening of Building Regulations and energy performance requirements.
Whilst energy performance is crucial for your new windows, so is security. Our triple glazed as standard windows are fitted with PAS24 accredited locking mechanisms and hardware to deliver ultimate protection and peace of mind.
For a smooth as ‘SILKA’ feel to touch, all SILKA products feature our exclusive SILKtouch sputter coat technology – helping our energy efficient windows not only look good but feel good too. The lightly textured surface offers a robust finish helps our products stay clean for longer.
As the largest component in any window design, it’s crucial that glazing offers the best energy performance. Triple glazing is becoming the go-to choice for energy efficient window and door products, and to help futureproof your home, SILKA windows are triple glazed as standard. We manufacture our frames and glass in the same factory too, to keep everything simple.
For energy efficient windows with style, our aluminium frames are available in True Black and Anthracite Grey – they’re the best colours for true SILKA style. Internally, White is available to blend with interior design plans and colour schemes.
