Ready for Mother Nature and Lower Energy Bills

Every Aztech custom vinyl window is specially engineered to be highly resilient and dependable. These products are durable, insulative, and carefully assembled based on your home’s unique design to ensure a precise fit. We achieve this by incorporating a resilient uPVC extruded profile, featuring a frame and sash corners that are fusion welded to ensure the strongest possible seal. Along with an innovative multi-chambered frame, you can expect the best in terms of durability, strength, and energy efficiency. These windows will maintain their resilience, precision-engineered shape, and water resistance for many years to come. In addition, all our windows are fully compliant to Canadian and USA manufacturing standards and are CCMC approved.

Vinyl is a material that is affordable yet offers unprecedented durability. Created using a plastic material known as polyvinyl chloride (PVC), it has a higher R-value that equates to improved insulation efficiency. This means your energy bills can be reduced over time through the minimized air conditioner and heater usage, made possible by our use of high-quality materials in addition to weather-resistant engineering.

Customize Your Curb Appeal

Whether you wish to boost your equity or simply enhance the appearance of your home, our custom vinyl windows are designed to perform and look their best. Plus, they are easy to keep clean with maintenance consisting only of soap, water, and old-fashioned elbow grease. These products come in a variety of styles, sizes, and colours to suit every home design imaginable. Whether you are interested in a traditional casement, bow, or another style of window, the Aztech team is happy to accommodate your needs.

Vinyl Window Glass Options

IGU – Insulated Glass Unit

All our Performance series windows come standard with 7/8” thick double pane insulated glass units (IGU’s) filled with noble gas Argon and with UV reflective LoĒ2-180® coating inside.

Optional Triple Pane IGU’s are available.  Third glass adds another degree of thermal and more importantly sound insulation.  The cost of the third pane may be justified in either extreme cold/heat conditions where an additional 2% in energy savings makes a difference or where triple-pane IGU is the only solution that would achieve the necessary level of sound insulation and comfort, e.g. in the proximity of a highway or a railroad.


Standard filler Argon, which comprises slightly less than 1% of the Earth’s atmosphere,  is non-toxic, inert, clear and odorless gas. Its thermal conductivity is roughly 67% that of air and it’s inexpensive, making it an attractive gas fill.  It is also guaranteed dry and would not produce dew inside the IGU which would compromise both its efficiency and transparency.

Krypton is very similar in its characteristics to Argon, except that it’s an even better insulator, albeit more expensive to produce.    When cost and functionality are considered, argon is a more efficient thermal barrier per dollar spent, especially in the larger (½”) gaps like we have in our standard double-paned IGU’s.  Krypton is sometimes used in the tighter ¼-inch to 3/8-inch (6mm to 9mm) gaps within triple-paned IGU’s.


Standard LoĒ2-272® glass is a simple means of maximizing your homes thermal efficiency year-round.  LoĒ2-272® reflects heat back to its source so summer heat is reflected outdoor and indoor heating in the winter is retained.  LoĒ2-272® also blocks up to 84% of UV rays to reduce fading and damage to upholstery and carpet.


Our optional LoĒ3-366® glass provides increased performance for high sun exposure locations. This top-performance glass is formulated to reject solar heat while letting light in. LoĒ3-366®, blocks up to 95% of the sun’s damaging UV rays.

There is a relatively new kind of coating developed by Cardinal IG that significantly improves the efficiency of the windows and sliding doors in line with the strictest Energy Star requirements for the products designed for the harsh Canadian climate.  Differently from LoE type coatings i89 goes on the 4th (innermost) surface of the glazing unit and is designed to reflect radiant heat.  A double-pane insulated glass unit with LoĒ-i89 can give the performance of a triple glass which is a great feature where panes are big and weight of each panel is a factor.

LoĒ-i89 is sputtered onto the indoor lite, the #4 surface, thus reflecting escaping heat back into the room and lowering U-factors. Coupled with the LoĒ² or LoĒ³ glass and Argon fill, this double-pane unit delivers performance even better than clear triple-pane window with no coatings. Part of that is that double glass allows better light transmittance and solar gain in winter when the sun is low over the horizon.

In addition to providing maximum energy efficiency in a double-pane unit, LoĒ-i89 offers other benefits.  Its surface is smooth and scratch resistant, making it easier to remove label adhesive residue and to clean.

Tempered Glass

Both Aztech Doors & Windows’   LoĒ2-272® and optional  LoĒ3-366®  glass are offered tempered.  Tempered glass is much more difficult to break, however if it is broken it would shatter into small pieces with no sharp edges and therefore is considerably safer.  This option is commonly used in to improve safety to the windows that are close to the floor or large windows located in high-traffic areas.

Obscure Glass

Obscure glass is a great option for areas where ambient lighting is required but either the view is unattractive and needs to be blocked or privacy is desired.  Various types of opaque glazing and sandblasted effects allow light to pass through but eliminate visibility.  Obscure option is available on both LoĒ2-272® and optional LoĒ3-366® glass.

Vinyl Window Features

Grilles and Simulated Divided Lites are available in multitude of patterns to replicate the look of your original windows or to add architectural interest.

Vinyl Windows

Between the Glass

Grille bars are located between the panes of insulating glass unit. Grille bars facing the exterior match the window’s exterior color, and bars facing the interior are available in White, Cream and Sandalwood.  Grilles between the panes combine easy cleaning with the stunning detail of a grille pattern. It’s the best of both worlds.

Simulated Divided Lites

Choose Simulated-Divided-Lites for an authentic divided glass look. Simulated-Divided-Lite bars are permanently adhered to the outside surfaces of the glass with a spacer bar between the panes of glass. Exterior divided lite bars are made of the same tough uPVC used on all Aztech Doors & Windows exteriors.


What is low E Glass and why we use low E Glass

In the United States and Canada, the established Energy Code requires that all homes now utilize Low-E glass, but what is it? In short, Low-E equates to a specialized film containing thin layers of metal that are essentially invisible to the naked eye. This film is heat-reflective and may vary in opacity depending on how dark or light the glass is that is used. This data falls under the term known as Visible Light Transmission (VT). For instance, darker panes of glass in windows that have a heavier Low-E film will have a lower VT rating. For ENERGY STAR® compliant products such as Aztech’s custom vinyl windows featuring Low-E glass, these ratings are provided by the NFRC. The key benefit is that Low-E glass can be up to four times more energy-efficient than clear glass, helping your home retain heat and cool air when appropriate even more easily.

Alternatively, you might consider ordering custom vinyl windows in a triple-glazed variety, which essentially adds a third pane of glass to the frame. This option features high-quality spacers that ensure a longer-lasting product and maximum seal efficiency, keeping moisture out.
