Hello helpful people,
I have a few questions regarding our converted loft which is currently
Situation: No insulation between rafters at all, this makes the room
feel very very cold in winter (drops to around 8ēc in the cold). There
is only a small amount of insulation under the floorboards between the
joists, it's extremely old and has turned black with dirt/dust. There
is a 1.7kw radiator in the room which does heat the room to a
comfortable temperature but an awful amount of heat is lost from the
roof - snow melts quicker than any other house on the street.
The ideal solution I am told is to remove all insulation between
joists, removed plasterboard which is covering the rafters and
insulate using Kingspan or Celotex boards and then fix the boards back
However this will cause a lot of upheaval to the room which is not
I am thinking of a good compromise that could be made. In loft space
there are storage compartments which can be accessed from doors in the
loft like this:
The storage space looks like this inside:
Walls of the room (view from storage area)
In this picture here you can see:
The arrow points to a gap which can be accessed from all the storage
Would it be possible to slide some insulation board up these gaps to
at least stop the heat loss from the main heated part of the loft?
Would there be problems with damp?
I hope you can visualise what I am talking about.
