Draught Proofing

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 our High Performance Sealing System (HPSS), we can eliminate these problems.Our high-performance Weatherfin brush pile becomes an integral part of your window. It is installed into the parting bead between the sashes, into new staff beads around the window, and directly into the mid and bottom rails of your sash windows.

Benefits of Our High-Performance Sealing System:

  • Your windows will open and close smoothly
  • Increased personal comfort
  • Reduced noise levels from outside
  • Improved window security
  • Reduced energy bills
  • Lower CO₂ emissions

Once professionally draught-proofed, rebalanced, and recorded, your sash windows will operate smoothly with fewer rattles and significantly reduced draughts, providing many years of comfortable operation.

How Do We Install Our High-Performance Sealing System?

  • Careful dismantling of the sash window
  • Weighing the sashes and checking weights correctly counterbalance
  • Routing Weatherfin brush piles into the meeting rails
  • Checking, cleaning, and lubricating pulleys
  • Re-cording windows with new reinforced waxed cotton sash cord
  • Renewing parting and staff beads with weatherpile carriers and Weatherfin brush piles
  • Removing excess paint obstructing sash running surfaces
  • Re-fitting rebalanced sashes in alignment with beadings
  • Painting all exposed timber with white primer
  • Final operational checks of the draught-proofed window
