Draught Proofing Sash Windows

Draught Proofing Sash Windows

Make your home warm and cosy while reducing your energy bills with our patented Sash Window Draught Proofing system.

Originally created by our founder Robert Tunnicliffe using his experience designing gaskets and seals for Ford Motors, the Ventrolla draught proofing system or Perimeter Sealing System as it's known in house, is the perfect solution for banishing common issues associated with the 3mm gap around sash and casement windows.

Sash windows have a 3mm air gap around the sashes to allow the sashes to slide past each other and operate smoothly.

It is this air gap that causes the inherent problems associated with sash windows, such as draughts, rattles, dust ingress and reduced energy efficiency. By installing the Ventrolla Perimeter Sealing System (VPSS) we can draught proof your sash windows and eliminate these problems without affecting operation or how they look.

Our high performance Weatherfin Pile becomes an integral part of your window, installed in our unique parting bead between the sashes, in the new staff beads around the window and installed directly into the mid and bottom rail of your sash windows, effectively draught proofing the whole sash window perimeter.

  • Suitable for both Sash and Casement windows
  • Tested to British Standards BS 6375:1-2009, equivalent to 71 mph winds
  • Also helps to eliminate rattles
  • Keeps the warm air in and the cold air out
  • Sash Window Draught Proofing also keeps out dust and dirt

"The standard of workmanship is superb: it far surpassed our expectations, very refreshing in this day and age. We love our new windows and think they are stunning. The house Victorian and draughty) is noticeable warmer. I cannot recommend Keith and Steve highly enough. They arrived when they said they would and were very accommodating, thoroughly professional and had a good sense of humour. Thank you!"
