Weather Seal Heritage or Victorian Windows
Draught proofing heritage sash windows allows the double-hung sashes to slide easily and will greatly reduce air leakage from the outside environment into your home. Our sash seals insulate the gaps inherent in heritage windows that allow irritant air pollution into your living space. Reducing air leakage helps to keep your period home cooler in summer and warmer in winter. Our draught sealing system does not alter the heritage appearance.
