Vertex Window is an authorized dealer of a few reputable window and door manufacturers/brands, endorced by window installers as good, high quality products.

We mainly serve Ottawa and surrounding areas, but we can also supply to Kingston, Cornwall, Montreal, etc.

 

Always Select the window brands certified by Industry Standard

No. 1: ENERGY STAR® 2020 Certified Windows and Doors

Vertex Window only supplies ENERGY STAR®- 2020 certified Windows. In comparison to the previous standards, where Canada was divided into three zones reflecting the severity of the weather conditions, now there are no zones. All Canada is under the same standards. The new standards are now equal to the most stringent that were previously in place.

All our windows met new ENERGY STAR® standards certification that came into effect on January 1st, 2020. As a consumer, when you get quotes from multiple suppliers, please verify if you are quoted with ENERGY STAR® 2020 Certified windows to make a valid price comparision.

Certification Requirements:

At least one of the following two critiria needs to be met: U-factor: <= 1.22 or ER: >=34

U-factor: measures the rate of non-solar heat transfer through the window. The lower, the better.

Solar heat gain Coeefficient (SHGC): fraction of solar radiation admitted through a window– either transmitted directly and/or absorbed, and subsequently released as heat inside a home. The lower the SHGC, the less solar heat it transmits and the greater its shading ability.

Air Leakage: the flow of air in and out of the home.

Energy rating (ER): a formula that balances heat loss, air leakage and potential passive solar gain.

No. 2: NFRC (National Fenestration Rating Council)

Vertex Window only supplies windows from manufacturing facility that operates under stringent quality processes imposed by NFRC certification programs. This ensures that your windows are made with highest quality standards all the time and are made exactly as the ones tested.

No. 3: NAFS-11

Vertex Window only supplies windows that meet NAFS-11. These high standards can be met when combinations of windows (two or more windows assembled together) meet certain performance grades. This is difficult to achieve.

How do we meet above Standards?

Top-Quality Hardware and Design is the Key.

 

No. 1: All glass packages are produced with German hot-melt machinery to provide the longest-lasting gas retention rate in the industry.

 

No. 2: Various Low-E Coating Options, also with Argon Gas

Interior LoE options available to meet customers’ different levels of performance needs: from energy gain to high R-value and UV-blocking features.

Double pane or Triple pane technology is designed to reduce the window’s heat conductivity and stop the cold from getting inside the house. To achieve this, Argon gas is used to fill the space between the panes. Argon gas conducts up to 50% less heat than air, and when coupled with triple pane construction you get added protection against heat loss, condensation and cold weather. Less heat loss translates directly into more energy cost savings for you.

Energy-gain LoE: designed to take advantage of the free heat from the sun.

Sun-shield LoE: designed to block unwanted heat and UV rays from the sun and increase R-values.

No. 3: Up to 10% Thicker PVC Profile Walls

PVC profile walls are 7% to 10% thicker than industry average for all awning, casement, casement fixed and picture windows. These are engineered for heavier, triple-glazed glasses and to comply with large window structural requirements.
