Getting ready to lay the floor of our dormer conversion, and I am wondering, do I have to insulate the floor in-between the joists?

I glued and screwed the firings to the joists. The deck is 18mm T&G OSB3 glued together and screwed down to the firings, four 5x50 screws in every joist. On top of this goes 200mm pir insulation followed by more OSB or marine ply, that's so I can fit solar at a later date.

One of the first things I did in fitting a kitchen was putting a datum line around the walls at around 1m up. I would check floor levels from this, you would be surprised how much they can be out, last thing you want is to find an integrated appliance, won't go under the worktop. Then I would use the datum line to measure down to draw a line for the height of the bases, and another for the wall units. Start level and stay level.

Decks on and covered with plastic, now to start on the floor, just had a price of £9.5+vat, for 18mm P5 chipboard, about another £1 for 22mm Area is about 50sqm.

Sorry guys only just seen this, thanks for the invite but I just don't have the time at the moment.

Thanks Nick, I know what you mean about poly glue, it's a pita if you get it on you as I always seem to do. The plan is ordinary D4 on the T&G and the poly on the joists.

What's the general opinion on gluing the osb down to the joists? I intend to glue them together but getting different views on whether to glue as well as screwing them to the joists, using a foaming glue to take up any slight gaps in the firings.

My SE detailed how he wanted it built. 3 175x50 C24 bolted together and structural screwed into the joists, this was the sole plate and runs the full 10m length of the bungalow. Then window construction with studs in-between, and finally a binder top plate, all in 150x50mm C24.

The quote included £16,000 for scaffolding, they wanted a tin hat put over the bungalow. The prices do seem insane, but from the two bare shell quotes of £60,000 seemed to be the going rate. So far I have spent about £10,000, for architect, structural engineer, joists, steel ridge beams, RSJ,s 3 off and bits and bobs like screws. Now about to start on the dwarf walls.

I got a quote for our dormer conversion this year. 7m x 10m bungalow with full length dormer. Quote was for 2 beds and 2 bathrooms ready for occupancy, £125,000. Just for a bare shell ready for me to insulate, second fixings, plumbing etc I was quoted over £60,000

I am currently converting our bungalow loft into bedrooms, my structural engineer wants 200x45 rafters sistered to the existing 100x45 so I can push the dwarf walls further back. Now I can't fit them in to sit on the plate and the new ridge beam in one piece, so can I cut them and join them over the dwarf wall?

Jack of all master of none now retired, well I thought I was, but the wife wants a dormer conversion on our bungalow. So that's what I'm currently doing.
