Roof Intruding into bedrooms?

[DominicJ]

Hopefully attached is a sort of picture of my house.
As you can no doubt tell, the upstairs bedrooms are partialy, in contact with the roof, and I believe this is my main remaining source of heat loss.  Now, my initial plan was simply to lower the ceilings, and get another few hundred mm of insulation in place, however thats not really practical.  The ceilings arent that high, the roof it just very low.
A 20w energy saver on a lamp fitting would be a danger to tall people, as would standing in the bath.

So my next thought was to "Box Up" part of the ceiling, marked in red, and fill the boxes with insulation, there by solving my problem.

Anythoughts?

moxi and stoozy are both in the process of insulation similar skeilings or sloping ceiling,you will be able to get a good idea from their threads on what to do

Why not just insulate on the existing angle to about 100mm thick & forget about boxing it?

Even with your box out you still have two weak points or have to over box by 100mm or so each way.

Hi Dominic. I can confirm what I did made a hell of a difference.  Daughter now saying too hot.  Need to get a thinner duvet.  Should be better in winter though as she had two las winter!
