If you like the look of painted timber windows but want the benefits of uPVC, you’ll love our range of foil laminate finishes, available in smooth and realistic woodgrain options. They complement both the exterior and interior of your home, and you can even choose one colour and finish for the outside and a totally different one for the inside.
Technical innovation
Built to last, the Kömmerling sash window boasts a host of features that meet the demands of modern living. Comfortably satisfying current building regulations, the Kömmerling sash window is rigorously tested for weather performance and strength, with PAS 24 enhanced security performance also available for extra peace of mind.
Colours
Traditional detail
The Kömmerling vertical sliding sash window features all the classic detailing found in period timber sash windows, including fusion-welded corners for a clean finish and authentic run-through sash horns. It also has a deep bottom rail for a true Georgian/Victorian look, with quick-release hinge arms so both sashes lift out easily for cleaning.
Design excellence
Since our foundation in 1991, we have installed thousands of sliding sash windows. We can confidently say that Kommerling’s vertical sliding sash window is the most impressive we’ve offered. The elegant sculptured outer frame, choice of heritage sashes and authentic sash horns make for a truly impressive finish.
Performance
We understand that being faithful to the period of your property is paramount, and that compromising on style is something you may be reluctant to do. This is where Kommerling comes in, combining traditional looks with modern performance.
Boasting superior draught proofing and severe weather performance, every Kommerling sash window is A-rated as standard, with a U-value of 1.2 W/m2K.
