Kömmerling window and door systems have been tested and proven to perform in all kinds of extreme conditions. One test took place at 2,300 metres above sea level with windows exposed for fifteen years to strong UV-radiation, freezing temperatures and heavy storms. From windows to glazing seals, everything proved to be in the same condition at the end of the test period and still performing effortlessly.

Kömmerling GOLD is the ultimate choice for today's environment. This range of windows, doors and conservatories has been exclusively designed by Europe's number 1 systems company, specifically for the UK's home improvement market. This includes a suite of matching casement, tilt & turn, entrance doors and french doors and there's also a perfectly matching PremiLine patio door to complete the range.

In addition there's also an 88 Plus system that's designed to achieve a 'u' value of just 0.8, an important benchmark for tomorrow's window performance levels, something we have achieved long before our competitors.

As you would expect from a market leader there's also an unrivalled choice of 44 colours
