Now then, I have a cupboard in the front bedroom above the stairwell, about 1200mm x 1200mm. It used to contain the boiler, an old one so it kept quite toasty in there in winter. The boiler is gone now . . .
It constantly suffers damp in winter - when you open the door, a blast of cold air hits you. The external walls are solid, no insulation, and this cupboard is on the corner of the house so has 2 external walls. I can already see some mould spores growing in there - I washed off all the mould from last year in the spring. It is definitely condensation, the roof was "refurbished" in Feb this year and given a clean bill of health.
The door into the cupboard is basically a pair of old wardrobe doors fixed to a wooden frame and the frame is faced with the wardrobe side panels!
The mould will soon become a concern when our bundle of joy arrives next year.
I want to know if I can - and should - insulate this little cupboard. I want to build a framework against the external walls to accommodate 50mm of insulation between/behind the studs, then face the studs with 18mm ply so I can install shelves galore in there. Would this be enough insulation? Would it work and stop the condensation and make the cupboard a bit warmer? And would I need any ventilation or space behind the insulation?
If money were not a concern I would have external insulation right around the house, but unfortunately it is too expensive and green deal is not for us - we dont plan to stay here longer than 5 more years.
