  • Does double glazing eliminate condensation?
    There’s a common misconception that condensation is caused by poor quality or defective windows and doors. However, this is not the case. In nearly all instances, the key cause of condensation is interior humidity. Two adults sleeping can expire up to half a litre of water overnight. This is why, in the morning, bedroom windows can have condensation. There are many steps you can take to stop condensation on your double glazed windows. Here are some ways to reduce condensation in the home: Ventilate Rooms Aim to open windows for about 20 minutes daily (yes, even in winter!) Use an Extractor Fan If you’re cooking or showering, using an extractor fan will help to remove damp air from your room before it can settle on surfaces and cause problems. Use a Dehumidifier You may want to invest in a dehumidifier, which will extract moisture from the air. Don’t Dry Laundry Inside Drying wet clothes inside significantly increases the amount of water vapour in the air. If drying laundry outside isn’t an option, ensure the space around your laundry is as ventilated as possible. Rearrange Your Houseplants Did you know that the more houseplants you have, the more moisture you’ll find in the air? Try moving your houseplants outside during the winter or choosing plants that absorb humidity, such as ferns, palms or cactus.
