WINDOW KOSAK alu 23 PASSIV

The window is characterized by excellent conductivity and modern design. The peculiarity of this window is, that from the outside, it is hidden behind the frame. The window is suitable for passive constructions. There is no glazing bar on the inside, as the glass is clamped with an aluminium coating. The window is sealed four times, which gives it excellent air tightness.

GLASS: Three-layer insulated glass with thermal spacer. By choosing glass, we have to decide for the most appropriate acoustic and thermal transmittance.

FRAMEWORK: It enables one-hand opening along the horizontal and vertical axis. We use the framework of a renowned German manufacturer.

WOOD: Three-layer laminated wood of the highest quality, without visible length joints of 78 mm thick, is used. Most of our products are made from larch or spruce. When choosing wood, we adapt to the wishes of the investor.

SURFACE TREATMENT: For surface treatment, we use the Remmers system, which, due to the four times application, provides the greatest protection against external factors. The customer can choose the colour according to our samples or the RAL colour scale.

SEAL: High quality plastic seals are installed in the windows. The characteristic of such seals is to remain flexible for a longer period of time than seals made on the basis of rubber.

ALU COATING: The purpose of the aluminium coating is to protect the window from decaying. The choice of alu coatings is varied, since each has its own design. Thus, windows can be adapted to the building's guidelines.
