The history of glass windows in Toronto

Glass windows have been a key part of buildings for centuries, offering light, warmth, and protection from the weather. When we think about Toronto, a city known for its blend of historic and modern architecture, it is interesting to consider when glass windows first appeared here. Windows in Toronto evolved alongside the city itself, reflecting changes in technology, design, and living needs.

Long before the modern glass windows we see today, early settlers in Toronto used simple panes or even oiled cloths to cover openings in their homes. In the late 18th and early 19th centuries, as Toronto (then known as York) grew from a small town into a thriving city, glass windows became more common. By the mid-1800s, glass-making technology had improved, and affordable glass panes started to be imported into the city.

These early glass windows were often handmade and quite fragile. They typically consisted of small pieces of glass put together in wooden frames, known as sash windows. Such windows allowed more light inside homes and public buildings, making interiors brighter and more comfortable during the long Ontario winters. This was a major improvement over the previously dark, enclosed spaces with shuttered openings.

The development of window technology in Toronto

As Toronto expanded through the 19th and early 20th centuries, the production of glass and frame materials became more advanced. Industrialization helped produce clearer and larger panes of glass, allowing for bigger windows with fewer seams. The introduction of plate glass and later float glass made it possible to install windows that were more uniform, strong, and visually appealing.

Windows evolved not just in function but also in style. In Victorian-era Toronto, decorative stained glass windows became popular in churches and grand homes, showcasing colourful designs and patterns. Alongside this, functional double-hung sash windows remained common for most residential buildings, providing both ventilation and insulation.

By the mid-20th century, improvements in glass production allowed for thermal insulated windows. These helped keep homes warmer in winter and cooler in summer, which suits Toronto’s climate well. The rise of aluminum and vinyl frames offered residents more durable and energy-efficient options. These materials required less upkeep than traditional wooden frames, matching the growing urban lifestyle in Toronto.

Modern glass window trends and options available in Toronto

Today, glass windows in Toronto combine style, energy efficiency, and safety. Many homeowners and builders select windows designed to reduce heat loss, block harmful UV rays, and lower noise from the busy city streets. Contemporary window options often include double or triple glazing, low-emissivity coatings, and smart glass technologies that adjust transparency with sunlight.

Types of Windows

If you are experiencing any of the problems listed above, it may be time to get new windows. But the question is, which windows are right for you? With so many to choose from, it can be difficult to make a decision.

In this section, we will review the windows that are available so that you can make an educated choice.

Awning windows lift out from the bottom of a window to open at a 45-degree angle. The angle works to protect the home from rain and other elements. They also provide the ultimate in airflow making them ideal for kitchens, bathrooms and other areas that are prone to mold and mildew due to humidity.
To ensure your awning windows are doing all they can to boost your energy efficiency while protecting your household, be sure to look for features like multi-point locking systems and fusion welded corners that will keep out water and air. A multi-chamber construction is also recommended for its ability to increase thermal efficiency, while providing insulation, durability and noise minimalization.

Casement windows have a crank that allows them to open to a 90-degree angle. The opening provides optimal airflow within interiors.
Triple sealed panes and an optimal number of internal air chambers will ensure the ultimate in energy efficiency while keeping the elements out. An advanced locking system is also recommended for providing safety and security.
casement window

Double slider windows have two panes that move along a track. They open on either side to overlap each other to let air in. They can also fully open into the house to make cleaning easy and provide ultimate air flow. Their ability to provide ventilation makes them ideal for humidity hotspots such as kitchens and bathrooms.

Sliding windows with optimal internal air chambers will be ideal for providing thermal efficiency and insulation.
single and double slider window

Double hung windows feature one pane under another. Both panes can be moved up or down on the track to allow the window to open from the top or bottom.

Double hung windows are a popular design and a favorite among homeowners. Elegant updates in recent years have made them a trendy option for homeowners. A multi-chamber construction will further provide structural integrity.

Because the windows have a flat exterior, they are ideal for patios, walkways and other areas that may be impeded by windows that open outwards.
double hung window

Single slider windows are a variation of double slider windows. Like the double slider variety, they open by sliding along their track, however, they open from one side only. If you like sliding windows, they are a more affordable option.

When low-E or low emissivity, glass is used, it results in the emission of low levels of radiant thermal energy. When combined with a krypton gas insulation, these windows can achieve optimal energy ratings.

single slider window

Single hung windows vary from double hung windows in that only the bottom pane will move when opening the window. They provide a classic style that works well in most interiors.

For the ultimate in energy efficiency, look for windows with a multi-chamber construction and an Energy Star rating.
single hung window

End vent slider windows have a fixed pane in the middle and two sliding windows on either side that move inward toward the center open. They are a good alternative to double slider windows that are better suited to smaller spaces. They also make a good option for those looking for a cost-effective alternative to casement windows.

In most cases, the middle pane will release to open inward to make for easy cleaning while letting in some much-needed fresh air.
end vent slider window
Picture windows are stationary windows that don’t open. Rather, they are meant to let light in, provide a view and work as a decorative element within the home. They are often paired with other types of windows like fixed casement, double hung or side slider.

What are the benefits of professional window and door installation in Toronto?

Professional installation ensures windows and doors are fitted securely and operate correctly, which improves energy efficiency, reduces drafts, and enhances security. In Toronto’s climate, proper installation minimizes issues related to moisture and temperature fluctuations.

How often should windows and doors be inspected or repaired in Toronto?

It is recommended to inspect windows and doors at least once a year, ideally before the winter season. Prompt repairs of any damage or wear can prevent energy loss, improve security, and extend the life of the installation.

What are common signs that window or door repairs are needed?

Common signs include difficulty opening or closing, drafts, condensation between glass panes, broken locks or handles, visible damage to frames, and water leakage during rain. Addressing these issues early maintains home comfort and safety.

How can I find a reliable window and door installation company in Toronto?

Look for companies with strong customer reviews, proper licensing and insurance, certified installers, and transparent pricing. It is also important to request references and verify experience specific to Toronto’s building codes and climate.

What should I consider before replacing my windows or doors?

Consider factors such as energy efficiency ratings, frame and glass materials, budget, security features, and the specific needs related to Toronto’s climate. Professional consultation can help make an informed choice tailored to your home.

Is it better to repair or replace old windows and doors?

If the damage is minor and the frames and glass are structurally sound, repair is often cost-effective. Replacement is recommended when there are extensive cracks, rot, poor energy efficiency, or security concerns that can no longer be addressed through repair.
