Insulation in dormer house "attic"

[ndp]

I have recently moved into a dormer house that was built 3 years' ago. The "attic" area (or I suppose the eaves) is insulated with a kind of aeroboard, but the job has not been done very well - aeroboard not correctly cut to size, some gaps, etc.

I am asking a few insulation specialists out to have a look at it and advise me as to what needs to be done to sort it out.

My question is - what do I need to know about insulating the eaves in a dormer bungalow? What is the best type of insulation to get?

(By the way, I'm not sure if it's relevant, but the house has underfloor heating and is mostly timber framed.)

Thanks for any help you can give.

Is the attic 'converted' already ? If not, and you can see all the timber work supporting the roof, it's not too late to fix.

Is the ceiling/floor, floored, yet? If not, insulate it (I had my attic done with Warmcel recently), and floor it - right out to wall plate connection.

Then, looking at the rafters, if some parts of the insulation are particularly bad, remove and replace the offending pieces. Small gaps, etc, can be foamed up to make tight. Pay attention to around the wall plate junction, etc. If the whole thing is very bad, it might be worth just re-doing the whole area.....

I'd then fit a vapour proof layer over the entire surface, taking care to seal well around wall plate detail, etc.

Next I'd fit an insulated plasterboard, again over the entire surface. Again, not too difficult.

Why did you go with this, and how did it work out?

Are these usual?
