Can we double glaze these or do we have to replace the whole window including new frames? We live on a main road so are wanting double glazing for noise reduction as well as for heating/cooling reasons? Not sure where to start???

We live on a main road so are wanting double glazing for noise reduction as well as for heating/cooling reasons? Not sure where to start??? I assume that the sash windows are double hung timber. It's unlikely that the glass width required will fit your existing frame, but check measure it anyway, you need 20mm before the bead, so how big is the glazing rebate to the edge? If you need to replace them and you want to use maintenance free aluminium (or PVC), then EcoClassic is the best window for timber replacement as it will fit straight into the same hole... others (apart from one inferior window) will require substantial rework to your wall to replace timber windows. Our window is the most energy efficient available in Australia today, and it can be configured for sound as well - but best of all it is at a very low cost... Thanks Ed "ECOECO" At 'EcoEco', we design windows, we design the best windows, we do it for you, so that when you’re happy we are happy.

Secondary glazing, which involves a perspex type material overing the inside frame of the entire window. Ideally though, you may wish to consider using a window replacment service. Most window companies, including mine, offer this service with no obligation and its the quickest way of assessing your cost options. Given that you have a 1940's home, you are really limited to timber or uPVC. Timber is the original material used on your home but has its drawbacks. They don't tend to seal as well as the multi point locking hardware that comes standard on uPVC windows and they also demand regular TLC to keet them servicable over an acceptable lifespan. uPVC is reknowned for its extreme durability and maintenance free qualities. Fortunately though, uPVC windows have similar frame aesthetics to timber and suit quite well. Their fixing-design and in-line reveals lend itself to very easy replacement. But the main reason to consider them is for their thermal and accoustic performance. Good luck with it, Brad ------ Re: Double glazed windows 4Sep 20, 2010 10:00 pm Ideally for noise insulation, you will want a large airgap (100mm) with thick assymetric glazing, and many people just go with secondary glazing. Double hung timber (single glazed) windows are one of the worst performing for noise insulation because they are not sealed, and if they are old, it's probably worthwhile to replace them with double glazed windows instead of using secondary glazing. If I were you, I would also consider changing the window type to a casement or a tilt and turn or an awning if sound insulation and thermal insulation are more important than design, because these window types are likely to perform better with like glazing. The other point worth mentioning is the importance of a quality installation for noise insulation - you can have great windows, but if the installation was not focused on acoustic performance, you won't get the full benefit of new windows.
