I have a reasonable sized loft space which i need to insulate in the correct way. The felt on the roof is the old non-breathable bitumen felt.
There is a ridge vent and soffit vents already installed on this loft space.
Please to all who choose to respond to this give me great detail from the insulation process, air gaps, if any, right up to vapor barriers. Any links of pages and videos would also be very welcome.
Thanks.
