How is draught proofing installed into my original sash windows?
Firstly your original sash windows are removed from the frame. This allows easy access to the pockets and weight cavity. The sash themselves are then taken to the mobile workshop for machining. The sashes are machined and have a brush inserted. Once the brush piles are inserted into the sashes, the parting bead and staff bead is also replaced and has a brush installed into it. The windows are then rebuilt and sash window furniture is installed to improve security as well. Normally a team of two professionals will be able to draught proof four or five windows a day depending on the condition of the sash windows.
