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.

Energy Star and Triple Pane Window FAQs
Top Energy Star Windows & Glass Questions:
What does “Energy Star certified” really mean for windows?
Energy Star windows are independently tested and labeled for top energy performance in your climate zone. In southern Ontario, that means low U-factor (keeps heat in) and ideal SHGC (lets in winter sun, blocks summer heat). They help lower bills and earn rebates.
How much can I save by choosing Energy Star vinyl windows?
Typical savings range from 7–15% on energy bills. That’s roughly $100–$300 per year for an average GTA home—helping offset the upfront cost over time.
Are rebates available in Ontario for Energy Star windows?
Yes—through Canada Greener Homes Grant and some local utilities. Eligible windows must bear the Energy Star Canada label. Omega assists with documentation for your rebate application.
How do I know if a window is rated for my climate?
Energy Star criteria vary by region. In Ontario, look for a U-factor ≤0.27 and SHGC that balances winter heating and summer shading. We verify each window’s NFRC label and confirm it’s suited for your locale.
Do Energy Star windows reduce condensation?
Yes—advanced glazing and insulated frames keep the interior glass surface warmer, limiting moisture buildup that leads to fog or frost.
Is Energy Star only for new construction?
Not at all. Energy Star applies across new builds, retrofits, and replacements. Even if you’re replacing old windows, going Energy Star is a strong energy-performance move.
Can a window lose its Energy Star status after installation?
No. Certification stays intact as long as the original unit and factory seals are in place. Damage or seal failure can affect labels, but proper installation protects its rating.
What glass features do Energy Star windows typically include?
They often have double or triple glazed insulating units, low‑E coatings, and inert gas fills (typically argon). Frames might be vinyl, fiberglass, or steel with thermal breaks.
Is Energy Star worth it in all homes?
Your climate, current window quality, heating system, and long-term plans matter. In cold-weather homes like those in the GTA, good Energy Star windows almost always deliver efficiency value.
Does the frame material matter for Energy Star performance?
Yes. Vinyl and fiberglass frames offer insulation and reduce thermal bridging. Omega’s vinyl frames are thermally optimized for Energy Star compliance.
Can Energy Star windows help with soundproofing?
They often reduce noise too, thanks to quality glass and tight seals. Triple glazing adds more acoustic insulation—great near busy roads or schools.
How do Energy Star windows compare to older double-pane units?
With low-E coatings, better gas fills, and upgraded frames, they reduce heat loss ~20–30% more than older windows—something your energy bill will show.
Will Energy Star windows prevent UV fading?
Yes. Low‑E coatings block much of the UV spectrum, protecting furniture and wood floors from sun damage.
Are there disadvantages to Energy Star windows?
They’re priced higher upfront—by 5–15%—but you recoup costs through energy savings, comfort, and a potential rebate or grant.
How do I verify Energy Star certification before purchase?
Check for the Energy Star label and NFRC data on the seal. Omega provides these in your contract and even helps check climate zone specifics.
Do skylights need to be Energy Star certified?
Yes—Energy Star also applies to skylights. They’re tested for U-factor, SHGC, and air tightness suitable for your region.
Can a poorly installed Energy Star window lose its efficiency?
Absolutely. Proper flashing, insulation, and sealing are essential. Omega’s installation process is certified to preserve Energy Star performance.
Top Triple-Pane Windows & Glass Questions:
What are triple-pane windows and how do they differ?
They have three glass layers with two sealed gas spaces—usually Argon or Krypton—along with Low-E coatings. That enhanced structure boosts insulation and reduces noise.
How much more efficient are triple-pane windows?
They can be 40–50% more energy efficient than single-pane and 10–20% better than double-pane units—ideal for cold climates like ours.
Will triple-pane windows cut down on outside noise?
Yes. Their extra glass and air gap can reduce noise by an additional 3–5 dB compared to double-pane and often 10 dB compared to single-pane units.
How much do triple-pane windows cost?
Typically between CAD 800–$2,500 installed per window in the GTA. Factors include size, frame, coatings, and hardware.
Is the added weight a problem?
They’re up to 50% heavier, so Omega uses reinforced frames and brackets and assigns a two-person install crew to ensure proper handling.
Do they maintain interior comfort better?
Yes—cold spots near windows are greatly reduced. Rooms stay warm near the glass even on freezing days.
Do they help with condensation?
Because the inner glass stays warmer, condensation is much less likely—a boon for moisture-sensitive bedrooms and bathrooms.
Are Low-E coatings important in triple-pane units?
Vital—they enhance U-factor and modestly block solar heat gain. We customize coatings based on orientation and sun exposure in GTA homes.
Are they worth it over double-pane in Ontario?
For many homes—yes, especially for passive, tight-envelope houses or noise reduction needs. But they cost more and offer diminishing returns if you only replace a few windows.
How long does payback take?
If winter heating dominates, recovery occurs in 10–15 years. For milder climates, payback may stretch beyond two decades.
Do triple-pane windows add security?
Thicker and stiffer IGUs make breaking in more difficult. We also install strong locking systems and reinforced frames.
Can I retrofit existing frames with triple-pane units?
Usually yes, if the rough opening accepts the thicker unit. Retrofitting is faster but full replacement often gives better performance.
How long do triple-pane windows last?
Comparable to double-pane—20–30 years or more if properly sealed and maintained.
Should I use triple-pane on all windows?
Not always. Use them where you need max insulation/noise control—north-facing, master bedroom, basement. Double-pane is enough elsewhere.
Does local code require triple-pane windows?
Not yet in Ontario. But for Energy Star Version 7 equivalent, they’re becoming the top performer, especially in cold climates.
Do triple-pane windows need special maintenance?
Routine cleaning and seal inspection—no extra care. Just ensure hardware is lubricated yearly, and glass stays clean.
