External harmony

Optimum 79N US windows

The hidden window sash of Optimum 79N US promotes integration with the surroundings. The sash hidden behind the frame makes the structure blend in with the building’s façade, creating external harmony . Aluminum windows are characterized by very good thermal performance due to the use of special profile insulation technology.

The best visual effect is guaranteed by single-leaf structures. From the outside, they look as if only glass was installed instead of windows.

Colour

Color versions of profiles used in the production of Optimum 79N US windows are created using one of two processes – powder coating or sublimation. The first one guarantees a smooth coating – without imperfections such as streaks or wrinkles – in various RAL shades. The second one allows you to create aluminum structures in wood-like colors. The variety of available options allows you to give your joinery a unique character.
