In the case of PVC windows, angular profiles and slim frames with shallow basic depths of around 74 mm are used. For refurbishment depths from 70 mm and for higher energy savings 80 mm and more are the order of the day. Regardless of whether you look at the windows from the outside or the inside, the modern frame design focuses on minimalism and restraint, so that the entire façade of the house appears open and calm.

Daylight in living areas is becoming increasingly important, which is why there is a trend towards large formats for windows and doors. Wall-high window fronts or large sliding elements open up new architectural design possibilities: therefore the question arises as to whether, when modernizing, one should simply replace old windows with new ones or opt for larger elements right away, thereby giving the house façade a new and modern style. 

Modern PVC windows have the resistance classes RC1 and RC2, whereby RC2 is recommended for security reasons. Of course, windows can be equipped or retrofitted with additional security technology. Special glazing techniques exist, e.g. bonding, burglar-resistant PVC frames, fittings with mushroom pins and additional locks or grilles. These investments can be particularly useful for patio doors or windows on the ground floor.

There are modern PVC windows with clever rebate ventilation systems integrated into the frame, allowing for ventilation without opening the window. The air from outside is filtered. If you live next to a major road and still want to enjoy peace and quiet, PVC windows with higher sound insulation values are an option.

Modern window shapes are just as diverse as the architecture of a building or the individual lifestyle: The spectrum ranges from timelessly straight lines to round arches and triangles to trapezoidal or circular. Today a suitable PVC window for every style of façade from the Wilhelminian period to Bauhaus and the post-war and post-modern period to the efficiency building style of the 1990s and early 2000s exists. Various frame and sash heights or sash depths, forend and transom constructions, all-glass or glazing bars characterize the appearance of both modern and historical façades.
