Energy Efficiency Upgrades Are Important

The cost-efficiency is also on-point, seeing as how roofing might be a substantially more expensive project. Overall, switching to quality double-glazing windows can save up to $250 per year. Now, keep in mind that you don’t replace your windows every year, which makes the ROI on this home improvement project quite impressive.

So, for all those who are determined to try and find the best windows for their home (energy-efficiency-wise), here are a couple of factors to look out for.

Pick The Right Material
When choosing a window frame material, you need to look past the aesthetics. The emphasis here goes to heat transfer properties (the lower, the better). In this case, vinyl is usually the safest choice. However, you can also go for wood. Composite wood frames are quite energy-efficient, but they can be a bit more challenging to maintain. Still, if you don’t live in a region with harsh weather shifts, this is a great choice.

On the other hand, aluminum and other metal frames are not the best insulators. Sure, they have their advantages, but they’re not ideal even with a great thermal break. On the other hand, they have excellent durability and are easy to maintain.

Find a Window with a Great Thermal Break
The highest window efficiency always comes from thermal break windows. These can reduce heat loss by 20%-40% when compared to their regular counterparts. The way this works is quite simple. There are multiple panes, which separate the frame into the separate interior and exterior sections. The break itself, although composed of air, poses an additional barrier. Most common windows are either double- or triple-glazing (which means that they have either 2 or 3 panes).

This is what makes these windows A-rated and allows them to achieve a much lower U value.

One more advantage of thermal breaks is the fact that they strengthen the frame. You see, they reduce the likelihood of condensation, which increases the longevity of these windows. Still, when looking for energy efficient windows , your first priority is heat-transferring properties.

Low-emissivity (Low-E) Glass
Another thing you might want to consider is whether the glass used in these windows is low-emissivity. The role of this glass is to minimize the amount of infrared and ultraviolet light without reducing the amount of light that enters the room. The way this is achieved is through a thin (almost microscopic) coating. This coating is transparent, which allows for the transition of light between two environments, but it stops heat.
