Hello guys I am doing a self-DIY conversion on my loft and I have two dormers.
It mentions I need a U value of 0.28
"270mm Fibre Glass in Roof Space"
Min Value 0.18"
It then mentions Dormer Cheeks of PVCU Clanning, 12mm External Ply wood, 100x47 Framework. Rigid Insulation to Maintain Value of 0.28.
I would like to purchase the best quality insulation v the space is consumes internally on the dormer. I am not sure how to do the calculations could someone please give me some guidance.
Thanks
