Types of Window Glass: A Guide for Ontario Homeowners
Living in Ontario means preparing your home for dramatically different climates. From humid summers to cold climates with biting winds, your window glass plays a major role in comfort, durability, and your home’s energy efficiency. At Premier North Windows & Doors, we help homeowners understand the different types of window glass available so they can choose the right glass for every room, renovation, or new window installation.
Energy Efficiency: Double-Pane vs. Triple Glazing
In colder climates like Ontario, energy efficiency directly affects indoor comfort and energy bills. Choosing between double-pane and triple-pane glass is one of the most important decisions for replacement windows.

Double-Pane (Double-Glazed) Windows
Double-pane or double-glazed windows use two panes of glass separated by a spacer and sealed air space filled with argon gas. This form of insulated glass reduces heat transfer and heat loss, improving your home’s energy efficiency compared to older single-pane units made from basic float glass or standard glass.
Modern double-pane glass often includes a low-e coating (low-emissivity coating), a microscopic metallic layer that reflects infrared heat while allowing natural light to pass through. This reduces solar heat gain in summer and minimizes heat loss in winter — resulting in measurable energy savings.
If you’re replacing outdated single-pane windows, upgrading to double-pane energy-efficient windows will immediately improve comfort, reduce condensation, and help lower energy bills.
Contact Premier North Windows & Doors for a free consultation.

Triple-Pane Glass (Triple Glazing)
For maximum performance in colder climates, triple glazing offers superior insulation. With three layers of glass and two insulating air-space chambers filled with argon or krypton gas, triple-pane glass significantly reduces heat transfer and outside noise.
Triple-pane glass improves soundproofing, making it ideal for homes near busy roads. It also enhances your home’s energy efficiency with industry-leading U-factors. For casement, double-hung, skylights, or large feature windows exposed to wind, triple-pane glass delivers exceptional durability and performance.

Safety and Security: Tempered, Laminated & Impact-Resistant Glass
Safety glass is essential in high-traffic areas, bathrooms, and near doors. Understanding the types of window glass for safety helps reduce the risk of injury.

Tempered Glass
Tempered glass, also known as safety glass, is heat-treated to be four to five times stronger than annealed glass. Unlike standard glass or annealed glass, which can break into sharp shards, tempered glass shatters into small, granular pieces rather than dangerous shards. This dramatically reduces the risk of injury.
For added strength without full tempering, heat-strengthened glass offers improved durability while maintaining structural integrity.
Ask us about tempered glass solutions for your new window or replacement windows.

Laminated Glass
Laminated glass is created by bonding layers of glass together with a polyvinyl butyral (PVB) interlayer. This interlayer holds the glass together if broken, preventing shards from scattering.
This type of impact-resistant glass is ideal for:
- Security-conscious homeowners
- Noise reduction and soundproofing
- Protection against UV rays
- Enhanced durability in harsh climates
Even if struck with force, the interlayer prevents easy entry and keeps the panes of glass intact. Laminated glass also blocks a significant percentage of UV rays, protecting flooring and furniture from fading.
Ask about laminated glass options for stronger, safer windows.
Decorative & Specialty Glass Options
Beyond performance, functionality and aesthetics matter. There are many glass options available, depending on privacy and design needs.

Obscured & Textured Glass
Obscured glass and textured glass allow natural light to enter while maintaining privacy. These are popular for bathrooms, entry doors, and sidelights.

Tinted & Decorative Glass
Tinted glass reduces solar heat gain and glare, while decorative glass enhances curb appeal. These different types of glass balance style, functionality, and performance.

Upgrading Existing Windows with Security Film
If your current windows are structurally sound but lack modern protection, upgrading doesn’t always require replacing them.
Security film can convert standard annealed glass or float glass into a more impact-resistant glass system. Applied directly to existing panes of glass, this film strengthens the surface and helps hold shards together if the glass is broken.
This added layer improves safety, reduces outside noise, enhances soundproofing, and adds another barrier against forced entry — all without replacing the entire unit.
Ask about security film solutions to reinforce your existing window glass.
Making the Right Choice for Your Home
With so many window glass types available — from double-pane insulated glass to triple-pane glass with krypton gas, from tempered glass to laminated safety glass — selecting the right window depends on your priorities.
Are you focused on:
- Reducing heat loss in cold climates?
- Improving noise reduction from outside noise?
- Blocking UV rays?
- Enhancing durability and safety?
- Increasing natural light while maintaining privacy?
Whether you are installing a new window, upgrading skylights, or choosing the right glass for casement or double-hung replacement windows, the right combination of glass layers, spacer technology, low-e coating, and gas fills like argon can dramatically improve your home’s energy efficiency.
Ontario homeowners need window solutions built for extreme climates. By selecting the appropriate types of window glass, you can reduce heat transfer, control solar heat gain, improve year-round comfort, and protect your family from the risks of broken glass.

Premier North Windows & Doors: Repair & Installation
We have provided window repair and installation to the following cities:

Regardless of the type of door or window you are interested in, no company in the Greater Toronto Area offers a wider selection at the best prices than Premier North Windows & Doors.
Unlike other kinds of window designs that open vertically, the beauty of casement windows is they swing open, like a door, thanks to a hinge attached to one side of the frame. All of our windows meet or exceed Energy Star compliance standards and come in double, or triple panes for maximum sound deadening and insulation properties. This type of window can be designed to fit any kind of architecture or decor, and contribute beauty and elegance to any home. Other features of these windows include inside decorative vinyl trim, multi-point locking systems, and sashes which accept a wide range of Energy Star rated glass options.
Federal Government Compliant
Did you know that performance criteria for windows are established through a federal governing body called the Canadian Standards Association (CSA)? The CSA mandates a rigorous set of standards for materials and manufacturing called CSA A440 pertaining to the thickness, hardness, and durability of glass in all windows sold and manufactured in Canada. Premier North Windows & Doors follows these standards to the letter, and only works with manufacturers and suppliers committed to the same for casement windows and other types of windows.
Work Only With Qualified Professionals
Over the years, we have seen customers experience the same problem: Working with companies or individuals who were not qualified or thoroughly trained to do the job for which they were hired — which ultimately showed in how their casement windows were installed. At Premier North, that will never be a problem. We operate under the principle that continual learning and training opportunities will drive our business, attract and keep clients, and allow us to offer the best products and services in the industry.
