Does Low-E Glass Look Different?


Many people have this misconception that low E glass is tinted and looks that way too. Well, that couldn't be further from the truth. The glass has a transparent coating, which means your windows will look the same, and you can enjoy the spectacular views.

Is Low-E Glass Worth It? 


You need to remember that the low E glass is an investment in your home, and they do cost more than normal windows.

Can You Tint Low-E Glass?

If you want to tint your low E glass, you should always contact a professional, which will be a better long-term solution. The professional will also let you know if it is okay to tint your low E glass windows. Once they give you the go-ahead, you can get it tinted in no time.

Can you Use Windex on Low-E Glass?
