Thanks for the information Alda. If I buy the silver insulation sheeting (Focus are selling Thermawrap at £25 a roll) and just staple this across the rafters, won't this affect the ventilation?
I'm trying to convert my loft into a clean, usable storage space and have begun boarding the floor. However, I live in a Victorian property which still has the original roof and no underfelt, so I get a lot of dust and dirt being blown into the roof void. I don't want to go through the whole process...
