Since the seasons have changed and cold fronts are sweeping in more often, you may be asking why do my home windows fog and crack? The answer lies in science. Today, Wholesale Home Improvements would like to explain these phenomena and give you tips on how to avoid them altogether.
Fogging up the windows
So why do home windows fog in the first place? It involves the seal on your windows. Most home windows have a least two layers of glass to help insulate the home better. Condensation occurs when that seal is weakened and breaks enough to let moisture in between the panes. Then you’re stuck with a fogged-up window.
It is more common in older windows, of course, as the seal is usually weakened over time. You’ll also find the problem is most prevalent on the side of the house that faces the sun because exposure to heat from the sun can accelerate the seal failure process.
To avoid this problem, carefully choose the best type of windows for your home. Pay special attention to the windows on the sunny side of your house. If you find that your budget won’t stretch to cover the best quality windows for your entire home, consider just putting the best ones on the sunny side and choose a good quality, but the less expensive window for the rest.
The windows are cracking up
All right, so how about cracks? Why do windows seemingly spontaneously break one day? It has a very scientific explanation. Imagine a glass baking dish in a hot oven. If you pull it out and immediately put cold water in it, what happens? Depending on the strength of the glass it can crack or even shatter suddenly. This phenomenon occurs because the glass in the dish expands unevenly as the cold water hits the dish, causing it to break.
It is the same process for a window, but usually much slower and less dramatic. Most often you will see this happen in large windows in a shaded or recessed wall. This is because the window spends a lot of time each day with the sun on one part and shade on the other. Eventually, the uneven temperature expansion will be enough to cause a stress crack.
Again, the best prevention is to choose the glass for particular locations in your home carefully. If you see that a window in your home, particularly a large one, will be in the conditions described here, it may be a good idea to select a thicker glass for that specific window.
