Hi
I have checked the search facility for insulation and found some very interesting reading however i would like some advise to my specific situation
a] Cold roof design with total attic area ~115m2, with ~33m2 of this floored with 18mm chipboard. The floored area has NO insualtion under the boards and the remaining area has only 150mm fireglass between joists [this will be increased to 300+mm]
As I would like to keep the floored area for light storage, what are my best options for improving the insualtion properties of this 33m2 area - rockwool, Knauf space board, blown insualtion or mix of insulating products, bearing in mind condensation risks etc.
b] I also have a dormer bedroom with 150mm fibreglass insulation in ceiling and dormer window walls! Will i have to rip out the plaster board walls and ceiling to put in proper insulation or is there another product like blown insulation although i am nervous of blocking the eaves ventilation with blown insualtion?
Advise appreciated
