Windows and doors can be a major source of heat loss. This is why more and more Canadians demand high performance windows and doors that meet ENERGY STAR standards. By considerably lowering energy costs, they represent substantial savings while providing comfort to your home or building. In addition, they help reduce potential condensation and attenuate outside noise.

For all these reasons, JELD-WEN Canada is a proud member of the ENERGY STAR program in the window, sliding glass door and entry door category. This program ensures that energy performance are tested by a laboratory accredited by the Standards Council of Canada.

You can be sure that all JELD-WEN products bearing the ENERGY STAR symbol are ideally designed to withstand all Canadian weather conditions.

In order to enjoy the benefits of JELD-WEN high-performance windows and doors, you must choose our low emissivity (Low E) glass, available as an option.

What is Low-E glass?

Low-E, or low emissivity glass has been coated with a low-emittance material designed to reflect heat. A window made with low emissivity glass repels ultraviolet rays that cause heat during summer months, but absorbs them and lets the heat in during winter. This type of glass can help you significantly lower your energy bills all year long.

What is ENERGY STAR® ?

ENERGY STAR is a voluntary Canadian energy efficiency initiative that helps consumers identify the most energy efficient products available. Administered by Natural Resources Canada, the ENERGY STAR program is internationally recognized and users include various levels of government, public service companies, manufacturers, retailers and environmental organizations.

In addition to administering the program, Natural Resources Canada oversees the promotion of its symbol and compliance with strict certification standards. ENERGY STAR qualified products include home appliances, office equipment, consumer electronics, heating, cooling and ventilation equipment, lighting and signage equipment, commercial and industrial products, and windows and doors.

How to Choose the Right ENERGY STAR® Windows and Doors?

  1. Consult the Canada’s ENERGY STAR map divided in climate zones in order to know which one you are in.
  2. The ENERGY STAR products that will suit your zones will be indicated on your windows and doors. Your retailer will be able to give you more information.
  3. Choose a model that suits the climate zone where you live or a superior zone.

ENERGY STAR® windows and doors will allow you savings that could reach 12%. There are many more advantages in the quality of these products: better comfort, less noises coming from the outside and less condensation than the traditional models.

Please view the JELD-WEN Technical Bulletin regarding changes to the ENERGY STAR rating system effective January 1st, 2020.

What is Performance Energy Rating (ER) and the U-Value?

The U value measures the transfer rate or the thermal conductance of a product. The lower this value is, the more isolating value of the product is.

The energy performance rating assesses a window based on 3 aspects: the solar heat gain contribution, heat loss by the frame, the glazing or the spare and the heat loss by air leakage, no matter the material and the assembly method. Also, the higher the ER value of a product is, the better its energy performance.

In order to get the ENERGY STAR sign on a product, the U or the ER values must be certified by a third party. 

How to calculate your Energy Savings with Windows?

We’ve tapped into our deep knowledge of Canadian building codes and efficiency standards to develop an online visualization tool that will help consumers or consulting professionals to understand the energy efficiency of their current windows, as well as understand the cost savings and benefits they could realize with JELD-WEN products.

In addition to energy savings, you will now be able to see what provincial and federal rebates you could receive if you choose to upgrade your windows.
