WINDOW KOSAK A+

The window has a standard design. It is distinguished by good sound and thermal conductivity, as well as a good price. The window is suitable for all types of buildings.

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.

DRAINING: On the lower side of the wing and frame, the window is protected with an aluminium draining profile. This prevents water retention on wooden parts and consequently prolongs the lifespan of the window.

GLASS BAR: The main task of the glass bar is the mechanical clamping of glass. The shape of the bars is selected by the customer and thus affects the appearance of the window.
