Internal Insulation
Internal insulation has been used for some time.

We now have access to the latest spray on coatings that have a thickness of just a couple of millimetres, and so no discernable size to the room is lost. The data below shows the increase in u-value. This is considered by many to be the best affordable return on investment of any home improvement. If you want to find out more just drop us a line . . .
