UPVC Windows Tailored To Suit Your Taste

Kommerling windows can be tailored to suit your individual tastes and our windows are manufactured and installed from start to finish using our own fully qualified tradesmen. So we can guarantee that your windows will be exactly how you want them.

Whether you are wanting just one window or your full house fitted with new windows, we have a range of colours available from Anthracite Grey to Black, and Traditional Cream, we are confident that we can help you achieve your design goals with an individual touch.

Working with Kommerling means your windows are eco-friendly. They have removed lead additives from all of their products, and are now focused on using recycled materials in as many products as possible.

Thermally Efficient, Appealing Design

Unlike many windows on the market, the Kommerling UPVC profile has a patented 5 chamber profile which provides a more thermally efficient performance. Kommerling C70 also utilises soft sculptured lines in both the frame and sash and the low line gaskets give a much slimmer sightline for a more appealing finish.

To compliment our Kommerling windows, we use Pilkington glass. As the market leader, Pilkington is world-renowned for offering innovative and high-quality products. From energy-efficient K glass, and toughened glass for safety, Pilkington also offer a wide range of textured glazing for the areas of your home which require extra privacy.

All of our windows incorporate multi-point locking systems to provide maximum security to your home. Contact us today on FREEPHONE 0808 1551872 to discuss the range of products available, or request a quote now.
