After a leak in the recently replaced* (?) flat roof, I have to replace a whole ceiling in a bedroom (3.5x2.5) and will take the opportunity to do another the same size (as they have only 1" of fibreglass at the moment!).
Height available between joists is 100mm - space has excellent through ventilation and therefore am aiming at a 60mm fill.
I know Kingspan and Celotex do the appropriate product, but my brain is getting old and knackered and I just can't nail down the right 'part number' or product description to make sure I order what I need (and also when I check prices). The distance between joists is an annoying
41cm so I'm unlikely to make maximum use of 1200mm wide sheets, which is a bit of a nuisance cost-wise.I'll be tearing down the existing ceilings, fitting the insulation and then get a plasterer to board and skim.
Any specific product/supplier recommendations very welcome as well as any suggestions for maximising utilisation of these sheets.
Thanks
Lewis
