Keep Your Home Warmer in Winter and Cooler in Summer
Glass & Spacer Systems Engineered for Ontario Homes
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. There are many LowE combinations you can do with triple glass and all of them will get you the highest levels you are looking for.

Below, you’ll find answers to frequently asked questions about performance ratings, cost considerations, and installation.
Energy Star® & Triple Pane Glass FAQ – Comfort & Savings for GTA Homes
Omega Windows & Doors Manufacturing created this section for homeowners across Toronto, Durham Region, and York Region who are comparing triple-pane windows for better year-round comfort. It covers ENERGY STAR® considerations, glass package performance, condensation control, sound reduction, long-term value, and project timing so you can decide whether the Energy Plus Series is the right fit for your home, climate priorities, and upgrade plans.
What is ENERGY STAR® certification for windows?
ENERGY STAR® certified windows meet energy-efficiency requirements established for the applicable climate zone in Canada. They are designed to support lower energy use, improved comfort, and better year-round performance.
What are the benefits of triple pane glass?
Triple pane glass offers superior insulation, noise reduction, and condensation resistance. It is especially well suited to colder climates and helps improve overall home comfort.
How does triple pane compare to double pane in terms of efficiency?
Triple pane glass adds a third layer of glass and an additional insulated cavity. Depending on the overall unit design, that can provide stronger thermal performance than many standard double-pane configurations, reduce heat transfer, and support lower heating and cooling demand.
Do all Omega windows meet ENERGY STAR® standards?
Omega offers window systems designed to meet applicable ENERGY STAR® certification requirements for the intended climate zone. The exact rating depends on the window style and glass package selected for your project.
Is there a rebate for installing ENERGY STAR® certified windows?
Potential rebates or energy-efficiency incentives may be available depending on current program rules and the product specifications selected. Omega can help homeowners review the offers and documentation requirements available at the time of purchase.
Does triple pane glass help with noise?
Yes. The third glass layer and added insulated space help reduce sound transmission, creating a quieter indoor environment.
How can I tell if a window is ENERGY STAR® certified?
Review the product documentation and certification details for the exact unit being quoted or installed. Omega can provide the relevant performance information and paperwork for the selected window package.
Is triple pane glass worth the investment?
Yes. Although it usually costs more upfront, triple pane glass can deliver long-term value through improved comfort, stronger energy performance, better sound control, and reduced condensation.
What kind of gas is between the panes?
Argon or krypton gas may be used between panes to improve insulation and reduce thermal transfer.
Can I combine ENERGY STAR® windows with other upgrades?
Yes. Pairing high-performance windows with insulated entry doors, improved air sealing, and efficient HVAC equipment can strengthen your home’s overall energy performance.
What are the U-value and SHGC ratings?
U-value measures how much heat passes through a window, so lower numbers generally indicate better insulation. SHGC, or Solar Heat Gain Coefficient, measures how much solar heat the window allows into the home. Together, these ratings help determine climate suitability and energy performance.
Do ENERGY STAR® windows reduce condensation?
Yes. Improved thermal performance can help reduce interior condensation, especially during colder months, though indoor humidity levels still play an important role.
How long do ENERGY STAR® windows last?
With proper installation and routine maintenance, high-quality windows can provide long-term durability and often remain in service for 25 years or more.
What kind of frames are used in ENERGY STAR® windows?
Omega uses multi-chamber vinyl frames with welded corners and insulating features designed to improve thermal performance and reduce heat transfer.
Will I notice a temperature difference immediately?
Many homeowners notice improved comfort shortly after installation, especially during hot or cold weather, because better-performing windows can reduce drafts and temperature swings.
Are there customization options for ENERGY STAR® products?
Yes. Omega offers a range of styles, colours, and glass configurations that can be selected while maintaining the required performance criteria for the chosen product package.
What climates benefit most from triple pane?
Triple pane windows are especially beneficial in colder climates like Ontario, where reducing winter heat loss is a priority while still supporting comfort through the rest of the year.
Do ENERGY STAR® windows block UV rays?
Yes. Many high-performance glass packages include Low-E coatings that help reduce UV exposure and protect furniture, flooring, and interior finishes from fading.
How soon can I schedule an ENERGY STAR® window installation?
Installation timing depends on the season, product configuration, and installer availability. Omega can provide a more accurate schedule once your design, measurements, and order details are confirmed.
Why choose Omega for ENERGY STAR® windows?
Omega combines certified performance, expert craftsmanship, and tailored customer care to deliver window systems designed for long-term efficiency, comfort, and durability.
What does it mean when a window is ENERGY STAR certified?
ENERGY STAR certification means the window meets recognized energy-efficiency standards for the applicable climate zone.
How can I tell if a window qualifies for energy rebates?
Check the eligibility requirements for the current rebate program and confirm that the selected window package meets the required performance criteria and documentation standards.
Is Low-E coating included on triple pane glass units?
Yes. Many triple pane glass packages include one or more Low-E coatings to reflect heat and improve energy performance.
Does installing ENERGY STAR windows help lower heating and cooling bills?
Yes. Energy-efficient windows reduce energy loss, which can support more stable indoor temperatures and lower utility costs over time.
