I plan to do a simple loft conversion. Its a 50,s semi detached bungalow and structure wise I dont see a problem but I think I will need energy efficiency calcs for our local council (North Ayrshire, Scotland). :?
Does anyone on here have any good links to learning how to go about these. I had hoped to use 100mm Kingspan but worried about the cold bridge on the rafters.
I want to do my own drawings as I have experience of drawings being a construction engineer but this stuff is new to me.
Cheers for any help and advice.
