Energy Efficient Windows by Omega Windows & Doors Manufacturing
Omega Windows & Doors, based in Toronto, proudly offers high-efficiency Energy Plus Series windows designed to handle the challenges of Ontario’s four-season climate.
Featuring triple-pane glass, low-E coatings, and a highly effective engineered multi-chamber vinyl frame design, these windows help reduce energy loss while keeping your home comfortable and efficient—now available across Markham, Stouffville, and surrounding areas.
Ideal for homeowners seeking energy-efficient window replacements in the GTA, these ENERGY STAR®-rated windows provide long-term savings, improved insulation, and reliable performance in both new builds and retrofits.
What Are Energy Plus Windows?
Windows are a critical component of your home’s energy performance. In winter, standard windows allow indoor heat to escape; in summer, they invite solar heat inside. Omega’s Energy Plus windows are engineered to solve both problems with advanced materials and precision design.
Each unit is built with double or triple-pane insulated glass, gas-filled chambers—using argon or krypton—to block heat transfer, and advanced Low-E coatings that reflect infrared heat while minimizing UV exposure. The multi-chambered uPVC frames are expertly engineered to enhance thermal resistance and maintain long-term structural durability.
This high-performance system helps regulate indoor temperatures, minimizes hot and cold spots, and improves year-round energy efficiency—without compromising on aesthetics or ease of maintenance.

LowE 180
When winter approaches our LowE 180 glass is the perfect solution. It keeps your home warmer and in return makes for a more comfortable living inside. It accomplishes this by blocking heat loss to the outside and lets the sun’s natural heat inside. By doing this it reduces your energy costs in the winter.
LowE squared
For an all weather glass that performs in the summer and winter look no further. In the hot summer days, its LowE coating blocks 63% of the sun’s heat and by not having a dark tint still allows you to see out without any haze. In the winter its design helps reflect your homes heat back inside reducing your homes natural heat loss.
LowE 366
For those customers looking to stop the heat when the temperature rises, LowE 366 is the only choice. The advanced LowE coating keeps the sun’s blistering heat out while still allowing natural light inside. Your home will stay cool and comfortable all summer long. As an added benefit to blocking the suns heat, LowE 366 also helps protect your furniture, carpets, etc. from the sun’s harmful ultraviolet rays which is the leading factor for fading.
LoĒ-i89 Glass (4th surface LowE)
For ultimate performance in a double pane window, Omega offers a 4th surface LowE. With a centre of glass U-factor of only 0.20 your double pane window now performs like a triple pane without all the extra costs. When i89 is paired with any one of our LowE’s it not only meets strict building codes for energy efficiency it surpasses them. An added bonus, i89 is easy to clean and more importantly does not block your view with any tinting or hazing.
Triple Pane
With triple pane glass you get the most energy efficient glass on the market. The extra layer of glass not only increases your windows U and R ratings it also increase sound dampening. Our triple pane units are a true 1 3/8 thick which allows for two 1/2 spacers which is the ideal thickness for maximum performance and energy efficiency.
