Clients mentioned that their entrance hallway and cloak room were cold and asked if I could suggest energy improvements.

This is a small lean-to extension to the main house with filled cavity walls.  The customers weren’t sure about the insulation leveI in the roof, which on inspection I discovered consisted of a badly distributed layer of mineral wool.  So I  suggested to use 100mm insulation boards fitted between the joist and sealed in with spray foam.

100mm insulation boards sealed between joists with foam and previous mineral wool laid cross-ways above joists.

The feedback from the customers was: we are very happy with the advice you gave and the work was carried out in a neat and efficient manner and is effective in reducing the heat loss in our hallway.
