Most manufacturers use argon to make their windows more energy-efficient. They fill the space between glass panes with this colorless gas, which blocks the transfer of heat. Knowing the pros and cons of using this type of gas in windows can help you make better purchases.
A Safe and Non-Toxic Option
Argon is relatively cheap, non-toxic and odorless. Plus, it won’t corrode the window frame. So, if you notice gaps in your window’s sealing, you shouldn’t worry too much about the gas that’s leaking.
As mentioned earlier, argon blocks the transfer heat and, therefore, raises the windows’ U-value. The U-value gives you an idea of how much heat a window can block. The lower the value, the better a window’s insulation capabilities. Argon-filled glass panes, combined with low-E coatings that reflect heat, can significantly raise a window’s energy-efficiency.
Windows filled with argon are cost-effective and energy-efficient, but they’re not without disadvantages. One of them is an argon-filled window’s lifespan. Unlike glass, argon doesn’t expand when exposed to heat. Repeated contractions and expansions might eventually puncture the window sealing, causing argon to leak out.
Argon or Krypton?
Argon can block a significant amount of heat, but other gases have better insulating capabilities. Krypton can give windows a lower U-value, but it’s a lot more expensive than argon. However, you shouldn’t concentrate too much on a window’s glass panes. After all, gas-filled window panes alone won’t make a window energy-efficient. You need to examine a window’s total performance.
To find out which type of window is the right one for your home, consult an experienced contractor. After all, your windows partly determine your home’s curb appeal, which is why they should complement your siding and roof as well.
