Hello all,
I am changing my existing conservatory which has a polycarbonate roof to having a slate roof with velux windows with velux vrtical element in the walls. Looking at the celotex website there are so many products, I can't decide which one is best.
I'd like to slate the roof with Redland Cambrian low pitch slate or similar and insulate between and below the rafters and have a vaulted ceiling.
Is the FR5000 board the better performer, I'd like to keep the rafters as slim as possible as there is a constraint on the overall height. The span is 2200mm and I'm looking for a ventilated space 0f 50mm above the insulation.
Basically, what's going to please the BCO?
Many thanks,
James
