Hello. I'm installing a bandtäkt roof. It will be open to the ridge, with a 5 cm air gap with masonite. But there are ventilation vents for the ridge.
Should I install them in at least every other slot? They cost quite a bit. But I want it to be done right. But not excessively.
The roof is 9m x 5m

I will have plank luffare that you place in the ridge. But they cost 2000 each. So I want to have the correct number. One for each compartment?
Do not know them, I mean this kind of variant. http://www.teknikhandboken.se/handboken/utformning-detaljer/sammansatta-detaljer/luftad-nock/
