frameless balcony glazing

Frameless balcony enclosures are modern systems based on aluminum rails and tempered glass. Tempered glass is very resistant to weather conditions, and its breakage is not a threat to passers–by.

The frameless balcony enclosure system allows to arrange windows in such a way that they form a completely invisible and uniform surface – a balcony façade. However, on warm and sunny days, it lets you fold all the glass panels in one package, so you can facilitate the free flow of air.

Enclosing the balcony with a frameless system is a practical cover that does not interfere with the architecture of a building. Its form gives a higher standard of use and a very modern and aesthetic design.

Frame balcony screen enclosures

Frame balcony enclosures are sliding systems. Sliding windows are made of aluminum profiles, which allow window glasses of a different type to be used. Windows slide both directions, and this is very easy due to the use of stainless bearings. Special fasteners prevent the automatic opening of windows from the outside due to weather or unauthorized access. It is also additional protection when children are playing on the balcony.

Frame balcony screen enclosures are a system that protects against wind or rain; yet, they can also ventilate the balcony. The Copal balcony enclosure is a buffer zone designed to provide savings on heating while the windows themselves almost always keep the temperature above 0 ºC, i.e. 32 ºF, in the winter.

The light Copal balcony screen enclosure system allows to create permanent frame structures as well, which complement the balcony enclosing structure perfectly. As a result, we offer a complete set for balcony processing, regardless of the stage of construction.

Our frame balcony glass system received the technical approval of the Institute of Building Technology KOT

Safety, quality, and a reasonable price make these enclosures more and more popular.
