Keeping you Warm, Whatever the Weather

Saving energy makes sense, as it puts extra money in your pocket and is good for the environment. KÖMMERLING 70 is a proven PVCu window and door system with far better levels of energy efficiency than timber windows and first generation PVCu windows.

Three aspects play an important role in window heat insulation: the profile’s heat insulating properties, the insulating glass with edge sealant and the wall fixings. KÖMMERLING 70 is class leading when it comes to energy efficiency, helping to keep your home both warm and secure.


  • Low line gaskets and weatherseals provide lasting performance and slimmer sightlines.
  • The full depth, central eurogroove helps make the windows and doors more secure.
  • Five chambered system is highly energy efficient, far out performing first generation PVCu windows.
  • Steel reinforcement is used where needed, to add additional structural strength.

Inspiring Colours & Rich Woodgrains

It is the windows that are decisive in lending your building that unique and unmistakable character. Besides size and shape, the colour scheme in particular and elegance of the materials play a vital role.

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.


Flat white

White is a timelessly elegant and neutral colour and because of the quality of PVCu from KÖMMERLING, KÖMMERLING 70 is extremely weather resistant, retaining its smooth, glossy surface. It is also easy to clean.


Foiled finishes

There are both coloured and grained foils within our range for both period inspired installations and those with a more contemporary appeal. You can also look to the benefits of dual colours for even more design freedom.
