Attic Insulation

martin6651

Any suggestions as to how to insulate an existing attic that was converted 20 years ago with out any insulation put in place during the conversion.

If is converted then you need to insulate the ceiling of the new room...assuming you want to keep using it as such?

Is/was the floor insulated? That will just make the room even colder.

There was some fibre glass type of insulation between rafters before the floor was put down.

So that's preventing any heat from the rest of the house getting to the new room.
Is it accessed via permanent stairs?

Is the ceiling plastered?

GreeBo

What's the problem you are trying to solve? House cold or that room cold or both?

Heat is getting to attic and getting lost through roof. Ceiling is plastered with no insulation between ceiling and internal side of roof. Rooms being used as bedrooms and they have radiators installed.

No insulation at all? Sounds awful. There's no easy solution. May involve removing plasterboard and insulating properly.

Feared some one was going to say that as a solution.

unfortunitly there are only a few solutions

take off the inside layer
take off the outside layer:eek:

or overboard with new insulation.

how much head room have you go . could you afford to come down 100mm

martin6651

Yes I think I could lose 100mm no problem.

You could then just over board with insulated plasterboard, buy as thick as you are willing to lose from the room.

But you will still likely need a plasterer to come in anyway to make good. you'd be amazed how much of a difference 100mm makes on a slope. I think removing the existing ceiling, rigid board insulation, and then putting back in place plasterboard is the much better solution.

Thanks for the advice guys. Was just reminded that we will be expecting visitors soon so the job will be put on the proverbial long finger for the moment and give me some time to think about which way to go.
