How To Choose Energy-Efficient Windows And Doors

Are you ready to update your doors and windows to more energy-efficient varieties but are unsure what all the terminology means? And you’re worried about making the wrong decision?

This guide covers everything you should know about choosing energy-efficient windows and doors. After explaining common terminology and offering helpful tips, we provide a step-by-step process for making the perfect choice for your property.

Let’s begin by defining energy-efficient windows and doors.

Understanding energy-efficient windows and doors

When referring to doors and windows, the term ‘energy efficiency’ means maximising energy expenditures to go farther with fewer resources. This means using less energy to heat and cool your home, as well as cutting extra costs from fans or electric heaters.

The best energy-efficient windows and doors provide several long-lasting benefits, including:

  • Lower energy costs
  • Fewer UV rays inside
  • Higher ROI for resale
  • Additional discounts and tax benefits
  • A more comfortable interior environment

Things to know about energy-efficient windows and doors

Before looking for energy-efficient windows and doors, you should get acquainted with specific energy-efficient terminologies.

Below are some of the most common terms and phrases:

Glazed windows and doors

The glaze of a window or door refers to the number of panes hanging in the frame. Single-glazed windows have one pane of glass, while double-glazed windows have two, and so on.

Single-glazed windows offer small energy boosts and are not recommended for extreme temperature swings.

Double-insulated windows and doors are designed to reduce energy costs and lower noise pollution even in less predictable environments.

Low-E glass

Low-E glass coating can reduce the UV rays and infrared light filtering into your property. Studies show it can boost energy efficiency and reduce energy loss by up to 50%.

Solar Heat Gain Coefficient (SHGC)

Solar Heat Gain Coefficient refers to how well a window or door can resist solar heat.

A low SHGC rating means windows and doors reflect more heat, keeping the interior of your property cooler. However, glass with a higher SHGC rating absorbs more heat, making it a better option for colder climates.

U Value

The U-value is like a measure of how well glass keeps things warm. It tells us how fast heat moves through the glass from warm air (not sunlight). When the U-value is lower, it means the glass is better at keeping things cozy. Glass with a low U-value is used to trap warmth indoors, especially in cold places or at night.

Both U-Value and Solar Heat Gain Coefficient (SHGC) are key indicators for windows and doors. While the U-Value measures how well glass insulates against heat transfer, the Solar Heat Gain Coefficient (SHGC) assesses a window’s ability to resist solar heat.

How to select the right energy-efficient windows and doors

Not all energy-efficient windows and doors are built alike. As you peruse your options and narrow down your shortlist, you must consider three specific factors: cost, location, and style.

  1. Consider the cost

The more energy efficient a pane of glass is, the more expensive it is to purchase. However, installing more energy-efficient doors and windows can save up to 12% on energy costs every year.

  1. Evaluate your location

The energy-efficient windows and doors you choose will depend on where you live. If you’re located in a colder part of Australia, for example, you may want a glass with a higher SHGC.

If you’re located in a warmer part of Australia, you may be content with a lower SHGC. Keep in mind that any location can benefit from low-E and double-glazed glass.

  1. Situate your style

Energy-efficient windows may be more or less attractive, depending on your personal preferences. You may need to browse several different styles to settle on the right one for you.
