New minimum requirements for windows and doors heat insulation.

Since the beginning of 2014, new energy efficiency regulations have been introduced in new buildings. The new requirements are the result of implementing the provisions of the European EPBD (Energy Performance of Buildings Directive), which emphasizes the increasingly energy-efficient solutions used in design, built and modernized buildings. The provisions laid down also set minimum requirements for thermal insulation for building baffles, including construction joinery. Windows and doors must have better heat transmittance values.
