Hello,
We have a house where the wall is IE60. Next to the house, 2m away, an "attefallare" will be built, intended to be used as a complementary residential building.
If I fire-rate the windows of the house facing the "attefallare," do I also need to rate the windows in the "attefallare" facing the house?
I don't think it's really clear in BBR, even though I see it states that you can't have any unrated windows (if it's less than 2m and then a bit), I'm wondering if this applies even if everything on the house is rated?
According to BBR, it's sufficient for one wall to be IE60 and then the other wall doesn't need any rating, but the windows in that wall still need rating?
