People have been living in homes for thousands of years. We’ve come a long way from the caveman days, and we’re now able to live comfortably in modern dwellings with ample natural light. But one thing that remains unchanged is that windows still play an important role in our lives. Here are 19 facts about home windows you might not know!

The oldest window ever found was in an Armenian cave, and it dates back to between 3400 – 3000 BC. It’s made of limestone with wooden hinges! – Window glass is just a very thick form of ice that has been melted. When the water cools down again, this happens inside your home windows as well. – If you look closely at the inside of your windows, you’ll notice that there are two or more panes. The outer layer is air, while the inner pane has argon gas in it. This makes it easier for heat to escape and prevents condensation from forming on cool days.

•  On average, a person spends about 90% of their time indoors. This is why it’s important to make sure your home windows are clean, so you always have a clear view outside and can feel refreshed. – Have you ever wanted an extra window in your office? Just tape two pieces of paper together, one on top of the other with open sides facing away from each other.
