I have discovered that my large bay window is uninsualted below the window.
The construction is as follows from the inside out.
12mm Plaster board, approx 140mm studwork, external felt, tile battens and vertical tile hanging.
I can get to the void within the stud work by removing the internal window board and pooring in some loose fill insulation beads.
The question is. Will this lead to possible damp problems?
