I have an question that I would like to clear up. My parents house has a loft that the wind can pass through because the eves are open. The house was built that way.
My question is two fold:
1, What is the reason for what I think is called a floating roof?
2, Would it cause any problems if the loft was sealed?
What I'd like to do is, insulate the pitch of the roof, board it out, sort out the normal loft insulation and board out the loft. I would want to allow for some ventilation or the roof space but not as much as the is now.
Would that be a problem and why?
Thanks in advance for any and all advice.
