cellotex question

[andymarshal]

Hi i am ready to fix cellotex to my roof rafters to complete a loft day room, the roof is felted and the tiles are about 6 years old so the roof is in good nick. the cellotex i have is 100mm thick i was thinking of cross battoning the rafters with 4 x2 and then fitting the cellotex in between these and then plaster boarding on top so basically there will be roucghly an eight inch gap between the underside of the roof tile and the top of the cellotex.

Is this ok or can i put the cellotex in between the original rafters

Cheers

Andy

I'm no expert, but I was reading this earlier and it appears you can (as long as you leave a 50mm air gap)
