Description

VIVA PLAST 8700 is a stand-out system with a construction width of 85 mm. The first-class quality as well as the multi-chamber technique of the profile take care of the best possible thermal insulation.

The reinforcing metal we use is 1.5 mm. It provides the strength and linear expansion.

The fittings are without any compromise in quality and security. We rely on one of the market leaders – “Roto”. The fittings are German, with special nano-coating against the aggressive sea air in Varna.

All of our Bulgarian windows have security hardware.

Advantages

The system is designed with a central seal. The central sealant significantly improves the quality of the windows and prevents the formation of undesirable phenomena such as water ingress, corrosion of the hardware, sweating of the frame and sash.

What is the central seal? Simply put, a third sealant (the so-called functional joint) divides the area between the sash and the window frame into two chambers - an outer chamber (cold and damp) and an inner chamber (warm and dry).
