Always fresh air in the roof attic
Given the tightness of modern structures, there seem to be problems with the roof attic ventilation, resulting in the condensation of water vapor in the attic.
Water vapor is a phenomenon of everyday life that occurs as a result of cooking, washing, watering, washing, drying clothes, etc. Water vapor created in this way must definitely be drained from a vent.
The introduction of fresh air inside the roof attic can occur either by opening the window, or by a special vent located in the roofing window.
3 Different types of windows for the roof attic
- The automatic vent has a ventilation capacity of 52m3 / h (this value is without the air filter, with the filter 40m3 / h) at a pressure difference of 10 Pa, depending on its width window. The entry of air into the room is ensured by the automatic regulation of its flow, thus providing a healthy climate in the roof attic, saving heat and energy costs.
- The vent manually adjusts the efficient air flow. When fully open, entry allows 43m3 / h of fresh air (this value is without the air filter, with the filter 35m3 / h) at a pressure difference of 10 Pa, depending on the width of the window. Due to the increased efficiency, the humidity of the indoor air is significantly reduced, resulting in concentration limitation.
- The vent manually adjusts the air flow. When the inlet is fully open, allowing the flow of 9m3 / h fresh air at a pressure difference of 10pa.

To reduce this effect the roof windows in the attic use a number of different vents.
The structure of the handle on the windows allows closing of three points that leave gaps for the entry of fresh air into the room.
A latch at the top of the attic window frame secures the window and allows fresh air to enter through the micro-opening into the roof attic.
