What Are High Performance Windows?

| 15 September 2016

When choosing new windows, many people select their new windows based solely on price, aesthetic and the convenience of having them installed. This means that, while they often end up with windows that look good from the street, they are not getting the best windows possible for their environment, climate, even the resale value of their home. What they should have opted for were high performance windows. If you have never heard the term “high performance window” before, below is a crash course on what that means.

What Are High Performance Windows?

They are energy efficient. High performance windows essentially mean “energy efficient windows.” According the Energy Star, Canadians can save up to $465 a year on their energy bills when upgrading their windows. They make it easier for your home to retain warmth in the colder months and expel hot air during the warmer months, reducing the need for central heating and air conditioning.

Energy efficiency is delineated by a rating system, which helps you evaluate the three main factors that impact efficiency. The first of these factors is the heat flow through the glass frame, which is the difference between the internal temperature of your home and the external ambient temperature.

The second factor is the window’s solar heat gain. In simple terms, it is the measurement of exactly how much of the sun’s energy (both visible and infrared light) is transmitted as heat into a room when it strikes a high performance window.

The third factor that goes into evaluating a high performance window is what’s known as air leakage. This is the air that is allowed into your home through cracks between the sash and the frame or at the point where your high performance window is fixed to the wall.

They are varied. High performance windows come in a wide range of styles and designs. There are thousands of different manufacturers specializing in different styles and functionalities, meaning you are able to get energy efficient windows that fit perfectly with your home’s interior and exterior design.

If you have been considering installing high performance windows for your home, but were hesitant because you were unsure what exactly that term means, the above information will hopefully have educated you on what they are and what they do. High performance windows are a great way to conserve energy, save money and make sure that your home is optimally heated and cooled all year long.
