How to Properly Care for Your Double Glazed Windows

Share This

Whether you already have double glazed windows for your commercial property or business establishment or are still thinking of having double glazing installed, there is one thing you should know for sure: how to properly care for your double glazed windows. Whilst windows that are double glazed do not require too much maintenance, especially if your windows are made from a material such as uPVC, you still have to make sure that they are cleaned and maintained every once in a while so that you will be able to make use of them for a long time (and maximise your investment).

Here, then, is your guide to the proper cleaning and maintenance of your double glazed windows:


Basic cleaning

 If you have double glazed windows with uPVC frames, you only need to clean them once every 4-6 months. But you also have to pay attention to the window frames’ sills and gaskets whilst cleaning. You can use warm water mixed with dishwashing liquid and wipe this mixture with a clean cloth on the windows. After wiping, rinsing is required using warm water. Once you have rinsed the windows, dry them with another clean cloth. If your double glazed windows have any stubborn markings or dirt, you can remove this with a dab of uPVC cleaner or any other cream-based cleaner.

For the glass in the windows, you can simply use a commercial glass cleaner. Spray a small amount of the cleaner onto a clean and soft cloth, and gently wipe away any buildup of dirt or dust. It is important to remember that you should never use any abrasive or chemical cleaners on your uPVC double glazed windows, as this could scratch (and ultimately damage) the window’s frame and glass.

Basic lubrication and drainage

Your double glazed windows should also be lubricated, ideally once every 4-6 months as well. The windows’ moving elements or parts should be oiled with the use of a light oil for lubrication. This will then remove surplus dirt or dust marks, especially from the frames and other moving parts.

Along with lubrication, your windows also need to be properly drained. Double glazed windows are generally designed with a drainage system that is comprised of slots, holes, and other channels for draining, which allow water to flow outside. To make sure that your windows’ drainage system works properly, the holes and slots should always be free from any blockage through the regular removal of dirt. If you would like to check the efficiency of your windows’ drainage system, you can simply flush it with water and see how the water runs.

We all know that double glazing has immense benefits, not just for your windows, but for your doors as well. Double glazed windows and doors are more thermally and energy efficient and have been proven to reduce energy bills. Having double glazed windows and doors results in enhanced comfort and better work productivity for yourself and your staff, as window specialists like can attest. But proper maintenance and care is required for double glazed windows and doors, and as long as you follow the tips mentioned above, then you should be able to maximise the benefits of this valuable addition to your commercial or business property.
