Casement Window Service by Ventrolla

A casement window's performance is upgraded using the same principles used on sash windows.

Although casement windows do not have the inherent 3mm gap that sash windows require in order to operate, they can still be draughty, unless they have a high grade sealing system installed.

Ventrolla’s two part process begins with the treatment and Renovation of the casement window. The second part involves Performance Upgrading it by draught proofing the window, using our unique Perimeter Sealing System. Using the same materials we use on sliding sash windows ensures the same high quality.

The system is installed into either the frame of the casement window or the sash itself, depending upon the construction of the casement window. If appropriate, the system can be installed into staff bead around the frame. The pile carrier is routed into the timber giving a permanent fixing point and making the system an integral part of the window.

Our system can also be installed in sash windows and other timber windows and doors.
