Energy-efficient glazing

The glazing occupies more than 75% of the window surface, that is why it is important for energy saving. Bolena window factory produces double glazing using the Austrian high-tech equipment Lisec.

For double glazing production we use the ClimaGuard Solar glass that protects from heat in summer and from cold in winter. The extra fine layers of metals, applied on the glass surface, retain its maximal transparency.
