We have Victorian sash windows that are in generally good condition, but rattle in the wind and are rather chilly in very cold weather. We are dedicated to maintaining the period style (so no pvc) but don't want to waste money on something that's not very effective. Noise is less of an issue now, but who knows what traffic on our road will be like in a few years' time!
We are pondering various options - replacing boxes and sashes with lookalike double glazing (which is what Cambridge Classics offers) or draughtproofing & installing slim double glazing in existing sashes (Cambridge Sashcraft option).
Have you had double glazing installed in sash windows - and was it worthwhile? Or might draught-proofing do the trick?
Any experience with Cambridge Classics, Cambridge Sashcraft, Sash Window Repair Company?
All feedback most welcome. Each company seems to have a contradictory position on best solution and it's so hard to know what to do!
