Converting Loft Into Habitable Space Is Current Loft Insulation Ok?
Posted: Sun Nov 03, 2013 11:40 pm
Hello All.
My house was built in 1992 with the upper storey in the roof space designed from the outset as a hobby / playroom and was fully compliant with building regs at time of build apart from having a drop down ladder instead of standard stairs. I now wish to convert this area into a habitable by fitting standard stairs which I understand will invoke current BR. The current insulation in the roof is 150mm fibre insulation between the rafters and over boarded with skimmed 9mm plasterboard. The questions are: will I have to upgrade to current BR insulation requirements, if so can I add something like Kingspan over the existing plaster boarded ceiling, and what thickness would be required.
Thanks.
