The main purpose of installing secondary double glazing sash windows in older buildings was to improve the thermal performance of window panes by draught-proofing them. It was also to reduce the spreading of heat through glass. There are also other benefits to secondary glazes.
In colder climates, having secondary or double glazed ones is essential. Trying to cope in the icy winter months with single glazed models will make winter a very miserable time in your life. There will be many older folk and young children who may die if temperatures drop to well below freezing as they do in some countries in single glazed homes.
Open-able panels can be either side hung casement, horizontal or vertical sliding sashes. These make it possible to get to the outside window to clean them. Letting fresh air in is made easier by being able to open it and let fresh air in.
Something to think about before even starting on the project of glazing them, is to check what repairs may be needed to make sure they are working properly. If they have not been regularly maintained, cleaned and painted they decay over time. Taking care of the frames and casings is a worthwhile investment.
The only time one would need planning permission for this would be if the house was situated within a conservation area. For listed buildings, the total replacement of a window is likely to require Listed Building Consent. Being aware of these regulations before you start will save problems with the authorities. If a homeowner is going to take the time to prepare the window for another application, he would have to be aware of certain precautions.
Single glaze is a poor thermal insulator. The glass is the most likely place that heat will be transmitted but heat can also be lost through the window frame. Secondary double glazing sash windows seem to be the answer to keeping heat in and cold out.
