Passive buildings are the latest generation of energy-efficiency. A passive house is an all season building, it doesn’t need an active heating system or air conditioning. Thanks to the use of passive technology it cools down and warms up by itself thus name „passive”.

Window  plays a very important role in a fully passive building.

For window to meet passive standards take into account:

  • The tightness of the window
  • Warm spacer bar
  • Type of glazing
  • Frame thickness



Advantages of passive construction.

Passive house is like a living organism working tirelessly.

In a passive house there is equal distribution of temperatures. High air quality which is very important for people with allergies. In a passive house, there is no sensation of cold or drafts.
Well build passive house protects against moisture and fungus
