Savings: Changing worn-out and leaking seals can save you up to 15% in heating costs.
Remember this: Many people are unaware that their home is poorly sealed and they suffer unnecessary consequences as a result. If you don’t know whether your windows are draughty, you can check the condition of the seals yourself, either visually or by passing your hand or a candle flame in front of the seals to feel for draughts. A window also serves as a way to recycle air, so find out more about the home’s air circulation arrangements before you start any sealing work.
Reducing your carbon footprint: Keeping your windows well sealed decreases your carbon footprint by 0.5% each year. If a million Finns did this, it would save the equivalent of 5,000 carbon footprints.
