JohnnyW Posted June 16, 2009 Share Posted June 16, 2009 Looking for a bit of advice from any builders or insulation expert on here. I've got quite an old flat that was built in 1900, it's had an attic conversion done by one of the previous owners. When I was lying in bed this morning trying to avoid getting up and going to work I started thinking that the height of the converted ceiling didn't go up to the full heigh of the roof so there must be a bit of space above the converted ceiling. There's a cupoard build into the stud work and the pasterboard at the top hadn't been skimmed so I removed the screw and low and behold there's a craking bit of space up there that runs the full length about 4ft in height so ideal for storage. One thing that's been annoying me since I moved in was the draft you can feel at the gabel end side of the building so I had a look at that side when I was in the roof space. There's no insulation behind the stud work and there's also air vents in the roof which I think is combining causing the drafts. Would there be any problems with stuffing some insulation down behind the stud work between the interior and exterior wall? I've attached two photo's of the space, not great quality as it was on my phone and pretty dark. Cheers Johnny Link to comment Share on other sites More sharing options...
JamieP Posted June 16, 2009 Share Posted June 16, 2009 Stuff away but leave the air vents alone and dont cover them. Link to comment Share on other sites More sharing options...
JohnnyW Posted June 16, 2009 Author Share Posted June 16, 2009 Yeah I wasn't going to touch them as I know it's part of the building regs. What the best sort of stuff to use Jamie? Something like Rockwool cavity slabs or just the normal cheap loft insualation? Also would there be any issue with laying some flooring up there so I could use it for storage space?

JamieP Posted June 16, 2009 Share Posted June 16, 2009 Yeah just drop some cavity batts down there, you can get them in various thicknesses, measure the gap and buy the right ones so they sit together nicely. What size are the ceiling joist and whats the span between them? Link to comment Share on other sites More sharing options...
JohnnyW Posted June 16, 2009 Author Share Posted June 16, 2009 Thanks Jamie! Ceiling joists are 30mm wide and 48cm apart. Link to comment Share on other sites More sharing options...
JamieP Posted June 16, 2009 Share Posted June 16, 2009 Thanks Jamie! Ceiling joists are 30mm wide and 48cm apart. How deep are they? if 100mm then you will be ok to board them just dont put to much weight in one place, (normal floor joists are 47x200mm) if you screw and glue the boards down you will get a far stronger floor.
