The level of humidity can be caused by bathing, cooking or even breathing. Misty areas on the exterior of a double-glazed window is normal. It means that the seal isn't damaged. But if it's between the panes, this is a concern and can cause issues for your home. Insulation It's not always the fault of the window, but rather the seals or protective measures that have worn away over time. They've let cold air be able to enter while permitting warm air to escape, which affects the efficiency of your home and could cause problems with mould development as well. This is the reason it's essential to insulate your windows to prevent this kind of issue in the future. There are a variety of insulation options available. It's important to consider your objectives in terms of temperature regulation, as well as how much you'd like to spend. For instance, you could purchase insulating films made of plastic that are available at hardware or home repair stores. These kits include tape and a large sheet of plastic film to stick to the windows. Just make sure to cut an opening for the rod that controls blinds to allow you to open and close your windows. These kits don't offer the same level of insulation as a full window replacement, but they can help to stop moisture from leaking between the double panes of glass. If you have windows that are misted, it's best to drill holes at the top and bottom of the glass to allow air to escape and to put in a desiccant that will take in any moisture that forms. After you've made the holes, it is important to let the windows dry prior to sealing them up again. It may take a while however it will stop moisture from accumulating in the gap and causing damage to the window or surrounding joinery over time. It's also possible to use foam or spray insulation to fill gap
