Hello everyone,
We are in the final planning phase of our house and are now wondering if, for our planned cold roof, two small roof windows for cross-ventilation are necessary.
Our client advisor says yes, but the general contractor considers them unnecessary.
How did you handle this in your projects?
Good luck, Julia

What do you mean by double-layered? The insulation level is located in the intermediate ceiling. The airtightness layer is also there. In the attic, I can see the rafters, the boarding on the floor, the underlay membrane, the unfinished masonry, and the insulation wool on the sloped walls.

Difference between cold and warm roofs:
*The thermal and moisture protection function of the entire roof space is integrated in a compact form within the roof structure. Depending on the arrangement of the ventilation layer, roofs are classified as ventilated or unventilated. In a ventilated roof (cold roof), this airflow layer from outside is located directly above the insulation – for example, this is typical in tiled roofs. Unventilated roofs (warm roofs) have no ventilation layer directly above the insulation.

Sebastian7910 Feb 2016 13:40I also have my doubts, which is why I asked.
We don’t have any ventilation grilles in the eaves either, because that doesn’t make sense with a warm roof—although many people do it.
And a warm roof doesn’t necessarily mean it’s actually warm up there. I’m not completely satisfied with our construction in that regard and now need to figure out the best way to solve this.
