Box-shaped windows

Box-shaped windows

The box-shaped windows produced by us are applicable in historical buildings being under the supervision of conservation authorities. This is a construction that combines the modern single-frame windows with a traditional box. Owing to such a combination, we have obtained a traditional appearance of the box-shaped window joinery with very good thermal insulation parameters.
