Energy Star Certification
You will get a more reliable way to save on energy bills, and help you to choose energy-saving windows and doors, reducing your energy consumption.
Fenêtres à haut rendement
Windows have many uses in your home from adding light to making your home more visually appealing. However, old, poorly made, drafty, or degraded windows can waste lots of energy and leave you very uncomfortable when weather is the most extreme. Here are a few big indicators that it may be time to replace your windows.
Improving the performance of your windows is an important part of an ENERGY STAR Home Upgrade because it reduces the energy waste associated with a leaky home and improves comfort. Windows and storm windows that earn the ENERGY STAR label meet performance criteria that are better than basic building code requirements and vary by climate.
Quel est le critère Energy Star?
Energy Star has a label indicating the certification scope of the product.Its ratings vary depending on the climate in your region. Here is the form about heat transfer coefficient and solar heat gain coefficient values of energy star standard as below.

What are differents of glass types?
Different glass types show different absorbance, reflectance and transmittance. Laminated glass provides maximum UV absorption. Coated glass is the second only to the laminated, providing privacy by obscuring the view but still allowing light to pass through. Click the video to explore more info about glass.

Conseil national d’évaluation des fenestrations
Il fournit des cotes de rendement énergétique pour les fenêtres et les portes. L’objectif du NFRC est de promouvoir l’efficacité énergétique et d’améliorer le rendement des bâtiments grâce à des évaluations précises et fiables des produits.
Quelles données l’étiquette NFRC vous montrera-t-elle?
Tout d’abord, vous obtiendrez quatre facteurs importants tels que le facteur u, le coefficient de gain de chaleur solaire, la transmittance visible et les fuites d’air comme ci-dessous. Le NFRC fait progresser l’efficacité énergétique et la durabilité environnementale dans l’industrie du bâtiment grâce à son système d’évaluation rigoureux.
U-Factor: It shows the heat transfer rate through a window, door, or skylight. It’s indicated in units of Btu/(h·ft²·°F). The lower the U-Factor, the better the window is at keeping heat inside your house in winter.
Solar Heat Gain Coefficient(SHGC): This indicates how well a window blocks heat from sunlight. It’s akin to the sunblock rating(SPF) of sunscreen. The lower the SHGC, the better the window is at blocking unwanted solar heat in the summer.
Visible Transmittance(VT): You can understand it like a glass of transparency water. VT shows how much visible light passes through the window. It’s like the clarity of your sunglasses; a higher VT means more light comes through.
Air Leakage: The rating gauges how much air passes through the cracks in the window assembly. It’s similar to the draftiness of a door; the lower the air leakage, the less air passes through, and the better sealed the window is.
Qu’est-ce que la norme NFRC?
La norme NFRC (National Fenestration Rating Council) mesure et certifie la performance énergétique des fenêtres, des portes et des puits de lumière aux États-Unis. Voici le tableau du critère officiel de la NFRC ci-dessous :

CSA Certification
The CSA marking is considered to be the equivalent of the CE mark. Both certifications ensure that products meet safety and quality standards.
Les consommateurs et les entreprises nord-américains font confiance au Groupe CSA
Today’s buyers put a high premium on energy efficiency. Consumers often choose products that they know will save them money on their monthly utility bill and perform better for the health of the planet. CSA Group energy efficiency marks demonstrate that your product has met the energy efficiency requirements for Canadian and U.S. regulators.

Conditions d’essai en différentes saisons
How will the product exert its heat insulation performance in summer?
Insulating glazing: Double-layer or triple-layer glass is with air or gas-filled spaces in between, which will reduce heat transfer through conduction and keep cool indoor in hot weather.
Low-E: Transparent layer reflects heat while allowing visible natural light to pass through, which minimize heat gain from solar radiation.
However, how to trigger the heat preservation in winter?
Sealing strips: Properly installed weatherstripping and seals can prevent air leakage from windows & doors, and minimize indoor airflow, so as to maintain a warm temperature in winter.
Le rôle de la structure à rupture de pont thermique
Does the thermal break structure pass the energy rating test?
By testing the U-factor of thermal break structure, it has been proved an excellent performance. For example, some of the U-factor of WANJIA™ products are from 0.19 to 0.22. The lower the U-factor, the better the thermal insulation performance, which gets the higher the energy rating.
Is it inferior energy rating efficiency for non-thermal break structure product?
Non-thermal break structure products often have worse sealing properties, leading to air leakage and potential airflow. Consequently, the interior of a building may experience more significant temperature fluctuations, requiring additional energy to maintain a comfortable indoor environment.
Comment le type de verre et la cavité affectent-ils l’efficacité énergétique?
Pourriez-vous expliquer plus de revêtements à faible émissivité?
Low-e is a thin and transparent coating applied to the surface of glass window and door. The purpose of these coatings is to reduce heat transmission and improve the energy efficiency of buildings. For example, they reflect solar heat away from the building, reducing the amount of heat that enters and keeping the interior cooler.
What are the pros of triple-layer glass with two cavities?
Improve insulation, three layers glass and two air gaps provide thermal insulation, which reduce heat transfer through conduction, convection and radiation, resulting in reduced exchange of heat between interior and exterior.

Australia Certification
The objectives of the Australian Fenestration Rating Council are to provide fair, accurate, and reliable energy performance ratings.
Australia Geographical Factors
Australia is situated in the southern hemisphere and is surrounded by the Indian and Pacific Oceans. More than 30% of the humidity is mainly distributed in the Northern and Southeast, which is related to climate closely.
Population Distribution Factors
According to the above charts, we find that the population of Australia is mainly concentrated in the Southeast because it mainly features temperate maritime climate and tropical humid climate.
