Loft Boarding/Insulation

Peartree

I've finally got around to doing something about the loft and have been speaking to a company that might do the work.

When I asked about having to raise the boards to accommodate 250mm of insulation, I was told it wasn't necessary. They use 150mm and then use a board which is an 18mm moisture resistant tongue and groove. They said this provided the insulation of a stud wall.

What do you think? Would this be sufficient or am I being spun a line?!

Many thanks.

Hiya,

I'm in a council house so it might be slightly different, but I've just had to lift the flooring in my loft so I could get the new standard insulation fitted which seems huge compared to what I had before.

Anyway that aside, I was told to relay my floor I'd need to build up the original rafters so to speak to just above the insulation, because if I failed to do this and just put the boards back down the pressure of the insulation being compressed would most likely pop my bedroom ceiling plasterboard off and I'd be responsible for getting it repaired even though it is a council house.

As for the boards themselves being counted towards the insulation depth, I've never heard of this before, but as I said I'm in a council house and they have set procedures and our loft being floored is an extra I've done personally.

I'd make a few more phone calls and it's worth going the DIY route for doing it, as although it's time consuming it's not too bad to do depending on the size of boards you buy so definitely worth considering. I'm going to be redoing mine myself with the help of my son and a male friend (with the drill) as mine has gone on holiday.

Sorry I'm not a lot of help.
