Ventilation at Home

Alexander: I'm very much for ventilation at home, good ventilation at home. And i that i can't wait for the day when people require it and when it's built in. But there are very clear regulations for home. The duct needs to be a single layer duckt work, so nothing can get caught. If you go over 400 c f M ah, that you need to a, you need to have make up air.
