Ventilation Technology

Ventilation system in the roller shutter casing

In the project, a slim but nevertheless well-insulating roller shutter box was designed and upgraded by a ventilation system with heat recovery. The result is an energy-saving and allergy-friendly ventilation system for new buildings and renovations.

 

Summary

The trend towards saving resources and the constant development of better insulation results in thinner and thinner house walls. This makes demands on the roller shutter boxes, which must not be wider than the walls and at the same time should not represent a weak point in the insulation of a house.
The developed top roller shutter box is made of expanded polystyrene (EPS) with a wall thickness of 240 mm and a height of 250 mm. The insulation values are better than future legal requirements and the system is also suitable for larger window fronts due to the stable material. For a comfortable room climate, the integrated ventilation system can start the air exchange by sensor control or manual control. In the process, the cold incoming air is warmed by the outgoing internal air before it enters the living space.
