Insulating and plasterboarding a lowered ceiling

[jenbrown83]

Hi

We've lowered the ceiling in our living room (Victorian terraced house) because the coving and ceiling rose are damaged and we don't have time/money to repair them (baby due soon). So far we've battened out below the coving line using CLS and joist hangers and have now come to deciding on insulation. What is the best way to insulate the ceiling (we're trying to make our very cold house a bit cosier for the little one) - should we fit insualtion above the battens so whole insulation boards/rolls can easily be slid in; or should we fit it in between the battens; or are we best just to fit insulated plasterboard directly to the battens? If fitting insualtion are we better off buying the celotex style boards, or the traditional insualtion wool?

The ceiling is going to have lights in the alcoves either side of the chimney breast, and also in the centre of the room - whether this affects what we choose to do?

Any advice much welcomed - let me know if you need more detail
Thanks!

If the house is centrally heated - what's the point?

Because its a big old victorian house with draughts and plenty of cold rooms - the house is only partially centrally heated (we're working on getting it all heated and double glazed) but even with central heating it is still a cold house.

Why do people fit loft insualtion and insulation in walls in new builds?!

rockwool is much cheaper than celotex type insulation and you can use as much as you like, space permitting, roll some over the top of the new timber then fit some between (consider lighting though), shouldn't be any need for insulated board but no reason why you can't, so long as you're sure the room won't get too toasty with what ever amount you decide to use, as reducing it afterwards isn't so easy

just my opinion.

After 2 years of sitting in jumpers and hats during the summer, and having to give guests blankets to stay warm i don't think we could have it too toasty! Thanks for the advice
