Is it possible to install double glazing into my original sash windows?

This depends on the width of the rebate of the sashes. In many cases the rebate is not wide enough in a period window to accept a second pane of glass.

There is also the issue of extra weight to the window meaning more weight has to be added to balance the window and in some cases there is not enough room in the sash box to accommodate these extra weights.

Ventrolla can install like for like double glazed units, however, it is worth noting that the need for double glazing is greatly reduced with the use of our unique Perimeter Sealing System.

The Perimeter Sealing System is a draught proofing system that seals the gaps found around the sashes and frames, through which the draughts, rattles, dust and noise come through the window.

Because of all these varying factors, each case has to be treated individually and we therefore offer a free no-obligation survey and quotation for your windows, from one of our qualified surveyors, to assess your options.
