Wooden windows EURO IV 78

The IV 78 window is a structure with an increased degree of energy efficiency. The wider profile and warm triple glazing unit provide users high thermal comfort. An additional advantage of the window are three seals that provide tightness and good sound insulation. 

As in the IV 68 system, the windows can be freely styled by adding decorative strips, wooden mouldings on cover moulds and transoms and installing a wooden drip. It is possible to make wooden profiles in the „Classic” and „Retro” style.

Fittings and glazing can be supplemented or modified, thus achieving the desired parameters: increasing the convenience of use and increasing anti-burglary and sound protection.
