KÖMMERLING 70 is your key to a playground of huge design potential. This universal system offers an unrivalled number of finishes whether for new buildings or as a solution matching the style of renovated historical buildings. Specifically, architects, local design partners and installers find in this system the maximum freedom they need to design a new look to the fabric of any property or apartment.

Helping to keep out the noise.

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 70 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.

Helping to secure your home.

Burglars often break into houses through windows, balconies and patio doors. KÖMMERLING 70 offers you protection against intruders because the window is designed to accommodate anti-burglary fittings, safety glass and the latest 3 Star security cylinders.

As a result, it is far more difficult for a burglar to break open the window or smash the glass. KÖMMERLING 70 in conjunction with the window and door operating hardware deters intruders and helps to keep your home safe and secure.
