Draught proofing

Draught proofing windows and doors is another way of saving money on your energy bills. Draughts are caused by cold air forcing its way through gaps around windows or doors.

These vents will allow fresh air to circulate the property and help prevent dry rot, which may develop if the timber is damp.
