Kömmerling 70 uPVC Windows

Improving your home’s energy efficiency enhances its comfort levels. It also reduces your energy consumption and subsequent bills, not to mention the impact heating and running your property has on the environment.

Windows from the Kömmerling 70 Window range enable you to enjoy all of these win-win benefits. Thanks to a five chambered profile, a highly engineered frame, and exceptional seal integrity, they offer class-leading energy efficiency that surpasses other 70mm window systems on the market.

To put this in context, the loss of heat through a building material is measured using a U-value. The lower the U-value, the better the material’s insulating performance and the greater its effectiveness in preventing heat transfer from inside to outside the building.

Windows from the Kömmerling 70 Window range easily achieve a U-value of just 1.2 W/(m²K). This impressive performance also complies with recent Building Regulations for new and replacement windows and doors, which were introduced in 2022.
