I was looking round a friend's house over the weekend as he is trying
to decide how best to insulate a bedroom ceiling. He has a dormer /
bedroom built into the loft (before he moved in) and at one end of the
room in an area about 6m x 2.5m, this has a good ceiling but it is
under the roof and peering up into the space through a removed light
fitting, it looks like was very little insulation put in that space
when it was built.

To add insulation now is virtually impossible without either removing
roof tiles, taking down the ceiling or, perhaps, blowing insulation in
the space as is done for cavity wall insualtion installation.

The best option seems to be to work from inside the room and add
insulation below the ceiling itself. The ceiling itself is in very good
condition - plasterboard which has been emulsioned. First thoughts are
either:

1. Put up ceiling tiles directly onto the existing ceiling.

2. Put up insulation on the ceiling and then tile over this.

3. Cut access holes (could just be one long hole that spans all the
rafters) and stuff in a load of loose rockwool, then patch and skim the
hole(s).
