The new Silka slim sash window range is now available after completing a rigorous testing process to achieve U-values of 0.8 W/m²K.

The system offers triple glazing as standard, which is designed to futureproof Silka against forthcoming legislation changes.

“We’re really excited to be bringing Silka slim sash windows to the market,” said Andy Jones, sales and marketing director for Silka in England and Wales. “Their 66mm profile thickness and 44mm triple glazing at no additional cost makes them the most exciting system on the market.

“It’s not just the profile and glazing combination that makes them so impressive,” continued Andy. “The Silka brand’s secret weapon is our ground-breaking thermal barrier, Thermafill, an innovative new method of insulating the cavities inside profiles, which helps to prevent heat loss.

“Our slim sash window is available in a dummy sash configuration, which is rare for aluminium systems. The square-edge detailing perfectly suits both contemporary and heritage properties, particularly for traditional bay windows with a dummy sash.

“Silka’s slim sash windows are available in dual colour options. The finish is absolutely stunning too, with exclusive Silktouch technology that offers a lightly textured, silky feel that stays cleaner for longer.

“Alongside our slim sash window, we have introduced a lift and slide door and will soon be bringing roof lights and a range of entrance and bi-fold doors to the market.

“We believe that Silka is the future of aluminium windows. It is the perfect system for installers looking for an aluminium glazing system to keep them ahead of the curve.”
