What do you know about energy-efficient windows anyway? Are you aware that they can help you save ~30% of your total heating and cooling energy? Or that they can increase the air quality in your house?

If you’re not familiar with energy-efficient windows and the advantages they offer, you’ll find everything you need to know below:

The components of energy-efficient windows

All the parts of a window contribute to its energy performance, from the frame to the glass and the other components. In energy-efficient windows, all the components have been designed to manage heat optimally and reduce energy consumption. Here is how the parts combine:

Low emissivity (Low-E) glass

Low-E glass reduces how much solar heat passes through your window without interfering with the light. So, you get as much light as possible from the sun but your house doesn’t get excessively hot during the summer. And during the cold winters, low-e glass reduces how much heat escapes, keeping your home exactly as hot as you prefer.

High-quality window frames

Window frames that offer strong thermal performance are the best companions for Low-E glass. Timber, composite aluminum, and uPVC are used in energy-efficient windows because they outperform standard aluminum.

Strong weather seals

Strong seals are required to block the cracks and gaps around the frames of a window. Some energy-efficient windows use compression seals to ensure that hot or cool air doesn’t escape from your home.

The Window Energy Rating Scheme (WERS) is used to rate the energy performance of various window types. It ranges from 0-10 stars, and the more stars your window has, the higher its energy efficiency.

Additionally, some window designs offer better performance than others, with double-hung, casement, and picture windows among the most energy-efficient.

The benefits of installing energy-efficient windows

Are you considering getting these windows for your home construction or renovation? In addition to getting a style upgrade, you stand to enjoy the following benefits:

1. Reduced costs: better performance from your windows means you lose less heat (or cold) and save a bundle on energy costs. Energy-efficient windows also require fewer maintenance checks, saving you more money. 
2. Better temperature control: high-performance windows give you more control over the temperature in your home, and you can eliminate hot or cold spots. During the summer, you can keep more cold air in, and in winter, you can reduce heat loss.
3. Protection from UV rays: the Low-E glass in energy-efficient windows protects against UV rays from the sun. This significantly reduces how much your furniture, rugs, carpet, paintings, and fabrics fade.
4. Increased soundproofing: due to increased insulation, energy-efficient windows reduce how much noise filters into and out of your home.
5. Reduced carbon emissions: by making it possible for your heater and air conditioner to perform more efficiently, these windows help you reduce your carbon footprint.

On a final note: don’t underestimate the importance of a professional installation. The most energy-efficient window won’t perform optimally if it’s not installed correctly. Work with skilled specialists to ensure you get the most out of your windows.
