KÖMMERLING 70 Windows Features


This window can also be made available with casement horns and Georgian bars, for a more period appearance, bolstered by the options of Irish and Golden Oak lifelike foiled finishes. It’s also a window that offers incredible levels of energy efficiency for a 70 mm deep window with a market leading Uw-value of 1.3 W/(mÇK) and it also offers impressive sound reduction properties to 42 dB.


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.


The following colours and woodgrains form part of our 2019-2020 range and benefit from an upgraded surface. For other options please speak to your local KÖMMERLING partner.
