Hey all thanks for reading my post,
I'm doing a standard loft conversion for my lads PC room cause him and his friends gather in the front room I gave them the loft but its on their budget

Main issue is the roof atm is 40 degrees was hoping to bring it down to room temp 20 -25,

Atm roof has silver bubble wrap up, I'm checking these insulated plasterboards out atm are they any good? £100 on them would cover my roof.
But will it drop the heat ? Maybe some fibreglass behind them??

I seen online people putting things like polystyrene on the roof tiles between batterns I was under the impression you leave a 3 inch airgap and go on top of the baterns ??

Any advice would be great my roof is standard triangle made from two rectangles measuring 4meters x 2.5meters each side

the loft is liek this 1 in pic but with floor and silver bubble foil allover roof atmn

any 1 know ? :(

the best way is to use a closed cell spray insulation. it goes onto the lining on the underside of the roof. stops condensation, heat transfer and is a very quick process. we used a company called Kozy lofts for ours.
