Knowing or understanding when to replace a window can be a tricky thing to figure out. If your house was built over 15 years back, it’s worth checking the windows to make sure they don’t need work done. The first key is to check if the windows are opening and closing properly. Also, another thing to look for is if there is consistent moisture content within the interiors of the window. Often, if the windows are not functioning as well, furniture; artwork; carpets; drapes may seem to fade and lose their color and glow due to them not being protected well by external weather conditions. There is also an aspect of the window being easy to use or not. Some very old windows may also be rotting and look worn out and falling apart. Some very old built windows may also not function properly to stop external noise from coming inside the house.
When all or some of the above is noticed; it’s a good idea to get your windows assessed by a trained window professional who will give the best possible advice. Sometimes a repair may be an option, however this can be judged by the technician only.
To increase energy efficiency double-glazing is the best option. It saves internal heat from escaping saving on energy bills and help to maintain the internal temperature. The two panes of glasses in a double glazed window are usually 16mm between them.
However, at times, it is possible to do a secondary glaze on the windows instead of double glazing. Sometimes homeowners do not wish to replace their windows as it may not match with their interiors or vintage furniture, which are unique and in good condition. Their requirement may then be only the energy efficiency. Secondary glazing is a solution in such cases.
