Passiv-Line PLUS

Passive-Line PLUS windows are characterised by a high thermal insulating power at a good price. With a pane with argon Ug = 0.5 W/m2K, the reference window achieves a heat transfer coefficient Uw of 0.7 W/m2K.

The innovativeness of this product consists of applying polyurethane foam and styrofoam blocks in profile chambers. Modern unconventionality also lies in the insert, made of PES tape, which insulates glass units. It is just an ideal solution for energy-efficient and passive houses.

Advantages of this product:

  • Energy efficiency — a significant reduction of heating costs
  • a decisively higher thermal insulating power,
  • a better acoustic insulation ensured by a triple set of gaskets


Windows addressed to customers looking for excellent energy-saving performance apart from exceptional sealing characteristics. The Passiv-line Plus system is a combination of a perfect barrier eliminating heat loss with enhanced sound absorption factors. The system has been awarded an MTP 2015 gold medal and many other awards. What is more, it is a product that significantly stands out on the market with its great price to performance relationship. Technologies used to produce this window will satisfy every customer who values a combination of modern technology with a classic line. The product is intended for passive and energy-efficient houses.
