If you like hot with a side of humidity, Florida’s the place for you! But while that’s fine outside, you want your home inside to be nice and cool. This is where energy-efficient windows come in. What do you need to know about energy-efficient windows in Florida? Well, here’s how the windows work, and more importantly, here’s how they can lower your energy bill. The more you know, the more you can save!
What Is Low-E Glass?
Have a glass of iced tea and you’ll notice how quickly the ice in the glass starts to melt and water down your drink. The same process happens when it comes to your home: glass transfers heat between a cold area and a hot area easily.
Low-E glass solves this problem: it prevents this transfer. Not only this, but it also blocks out many UV rays that can contribute to skin cancer. There are additional options such as tints and reflective coatings, but the basic idea behind Low-E glass is that it reduces the heat that windows absorb and then transfer inside. This helps to lower your energy bill, as your air conditioner won’t have to work as hard or as much.
What About Multiple Panes?
Double- and triple-panes provide airspace in the window. This is useful because heat transfers easily through a surface like glass – but it doesn’t transfer as easily through air. By having a buffer between each pane, it takes a longer time for heat to penetrate into the home.
Don’t Overlook Window Spacers!
Have you ever touched a car roof that’s been out in the sun all day? Metal conducts heat extremely well, which means metal window spacers easily transfer heat to window panes. Not only this, but metal expands and contracts with heat and cold, creating airflow around a window over time.
Good window spacers are made of materials that don’t conduct heat. Fiberglass is one such material. It’s still an airtight option for reducing airflow around a window, yet it doesn’t transfer heat easily and it stays resistant to airflow over time.
