Draught Proofing Sash Windows with Ventrolla

Sash window draught proofing system from Ventrolla

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 eliminate these problems.

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:

Manufactured from polypropylene, includes fin that stands 1.5mm proud of the pile.
Pile heights range from 3mm to 15mm, with a width of 6.7mm, to suit all gap sizes.
Silicone treated to improve water repellency and is ultra violet stabilised.
