Why does light make us happy?
Light is essential to human survival. It makes us feel happy and enhances our sense of general wellbeing. That‘s why a well-lit and inviting interior is an important aspect of an ideal living environment. Our Kömmerling 76 window system helps you to fulfil your need for a light enriched living environment with a well ventilated atmosphere.
Innovative profile technologies make it possible to manufacture windows with larger panes and greater rigidity from state-of-the-art functional glass. It also makes optimum use of sunlight to reduce heating costs, even when the outdoor temperature is cold. These windows maximise interior sunlight levels and ensure that your new or renovated home will light up your life.
- Intelligent profile design for optimised window performance.
- Increased depth to 76 mm offers better energy efficiency.
- Narrow sightlines maximise light transmission.
What do you need for a quiet and safe home?
How about considering new windows from the perspective of noise? This aspect is often neglected in window purchase decisions, yet sound insulation is essential to your family’s health. This is because subjectively annoying external noise can be a source of stress, distraction and disruption to your daily life.
Kömmerling 76 protects you and your family from noise pollution. Its innovative profile sealing technology in conjunction with sound-insulating glazing, ensures a peaceful and quiet living environment, even when you live close to a busy road. Compared with other 70 mm windows, it also offers better sound reduction characteristics.
- Application for effective sound insulating glass.
- Optimum sound insulation up to 48 dB with innovative seals.

So heat can get in, but not out?
Saving energy makes sense. It puts extra money in your pocket and is good for the environment. Ideally, energy saving should be simple, fun and convenient.
Kömmerling 76 is a brand new generation of PVCu window that ticks all the boxes. Not only do they offer unrivalled energy efficiency characteristics, but they also have beautifully elegant aesthetics in flush sash, casement and tilt and turn designs.
