Im having all sorts of problems trying to find the Wooden I-Joist sizes specified on my plans so im now thinking of going for standard timber joists, this will work out slightly cheaper too.
They have to go on 400mm centers to match the roof but what size should I go for, its for a loft conversion and the longest span is 5 meters
cheers
