Are you in the market for double-glazed windows? These are available at sites such as However, there are many issues to consider to make the best decisions. Here are some of the most important ones to consider:

1. Space

Make sure to consider the amount of space between the two panes of glass. Usually space ranges from 6mm to 20mm. As a general rule, you should look for a mini gap of 12mm to enjoy the best thermal performance.

Meanwhile, if acoustic control is important to you, then you should look for spacing of 150mm or less. One of the drawbacks of a wider gap is that there’s less insulation between convection takes place between the panes. This is an important issue to keep in mind because there will be some give-and-take if you want the double-glazed windows to be effective in keeping out the sound.

2. Frame

This is another option you’ll have when selecting double-glazed windows. The one you choose can help to improve the energy efficiency of the 2-pane windows. On the other hand, there are other materials that are less energy efficient.

The bottom line is that you should look at the big picture. Don’t’ just consider the glass but also the frame and other components that will determine how energy-efficient your window is.

3. Glass

There are different types of glass that can be used for the double-glazed windows. They include laminated and lower. These materials can help to make the windows, even more, energy is efficient and soundproof.

Which option should you choose? Laminated panes are better for blocking out sound, while Low-E glass is better for helping to prevent heat from escaping your home. When shopping for double-glazed windows make sure to consider which feature you value more.

4. Air/Gas

These are the two options for the space between the two window panes. Space works as an insulator to keep out air and sound from your home. That’s a good thing!

There are different types of gas that can be used to form the insulator. Argon is a common one due to its low conductivity properties. It’s advisable to do some research to find out whether air or gas is used for space. The particular gas that’s used is especially important as different ones have different properties.

Besides the air/gas, there’s also something called a “spacer” between the two panes of glass. This is a metal/polymer strip that separates the 2 panes of glass in the window frame. Using the spacers include a drying agent that helps to remove moisture that gets trapped in the space.

Keeping condensation out of the windows is more important than it might seem at first. That’s because when droplets land on the pane, they can form frost during the winter. That makes it seem colder inside during the winter, which causes people to turn up the thermostat. That, in turn, can increase your heating costs, which is something you probably want to avoid.
