No. Glass is not the best material for windows. We I guess there may be “more to it than that” if you want to really debate what all could go into this topic. Stained glass in beautiful in many cases but requires a lot of maintenance and breaks easily. We have all been to the church where the stained glass is ornate and looks heavenly! But you have probably also seen stained glass help together by take and glue and it didn’t look quite so good.
Maintaining a stained glass window takes special care because you really cant apply any pressure and just scrub the thing clean like you could an regular window. For this reason and more glass is generally not the best material for windows. If you’re on a tighter budget then vinyl may be a good option for you because they are now considered a generation behind as it comes to windows and many manufacturers can make them very inexpensively now. They are usually double-paned and you will almost certainly end up with a leak in between the panes at some point and you will curse the day you decided to have them installed.
Now there are composite windows (learn more) which are stronger and reflect or deflect more of the heat coming from outside and more directly from the sun. They can block up to 90% of the heat from coming inside. If you have old glass windows and upgrade to these windows let’s do a little simple math and say each saves you $10 per month in electricity. But they cost about $500 each installed. So you “break even” after 50 months. Could be worse…you could spend a bunch of money with no time horizon for payback or even worse end up with a product that requires substantial ongoing investment and will never pay itself back….like a pool!
