Definitely. While a single-pane sash window is naturally less insulating than a modern-day wall, the setup of professional draught-proofing can decrease heat loss by approximately 30%. Combining this with slimline double glazing can bring the window's thermal efficiency near modern-day standards.
For how long does the repair procedure take?
On average, an expert can restore 2 to three windows per week, depending upon the degree of the rot and whether the windows are being painted on-site or in a workshop.
Is restoration more costly than buying brand-new uPVC windows?

Yes. Much of the sound from outdoors gets in through spaces around the sashes. Once an expert sets up a draught-proofing system and thicker laminate glass (or slim double glazing), sound ingress can be substantially minimized.
