Casement Window in Toronto

Casement Windows: Everything You Need to Know

The elegant look of vertical casement windows has been in style for centuries, largely because they’re simple and provide a clear view. But these windows have kept up with the times, and are now available in all kinds of materials, finishes and with any pane you like.

Advantages of Casement Windows

Most casement windows are taller than they are wide (but not all styles conform to this guideline). All swing open from one side or the other (sometimes they can be pushed open by a crank) to let in fresh air. You can pair casement windows together to create different looks. French casement windows are two paired together so you can push them both open at the centre, which is a very traditional but luxurious look. Those with larger windows might pair several casement windows together, which gives you the advantage of being able to open one window to let in only a little bit of air. Larger window, on the other hand, would give you less control over a small breeze. Casement windows are available in all materials, like wood, vinyl, aluminium and clad-wood. You can match them to any colour you like, or keep them white for a clean, modern look. In fact, it’s easier to keep a modern look with casement windows as their design allows you to clean the outside of the window while you’re standing in your home. Of course, you’ll also need to remove any dust and debris from the window trim and track to keep your casement window in working order.

Casement Windows as Escapes

Ontario building codes require a certain number of escapes, either doors or windows, in specific rooms and per floor.  To meet these codes many choose casement windows because they easily open at 90 degrees. You can use awning-style casement windows which are wider and a great fire escape for basements and other challenging areas, as long as you’re still meeting the overall area requirements for a fire escape. However, it’s important to note that some casement windows don’t open precisely from the side. Instead, they hinge somewhere near the centre. This most often occurs with windows that have cranks to open. While they can make for a stunning look, these windows may not allow enough room for a regulated fire escape. You’ll need an egress casement window, which opens from the side, to avoid this problem. If you’re trying to meet escape requirements, contact the team at Thermo-Bilt. We can advise you on the proper type and size of windows you need.

When to Consider Casement Windows

While some casement windows can be hard to open, our casement windows at Thermo-Bilt offer effortless opening and closing. Our Greater Toronto Area factory uses an incredible manufacturing process to ensure the smooth operation of these windows. Contact us, if you’re interested in casement windows.

10 Signs You Should Invest in New Windows

Here are some unexpected signs that your windows need to be replaced.
  1. There is condensation and/or leaking around the window

Condensation on the inside of your window, or outright water on the floor next to them, signals that the seal on the window has become damaged somehow and water and air from outside are leaking in. If you ignore this problem, eventually the water will cause damage, from water stains to mold and rot, on the walls of your home. It’s best to get new windows right away.
  1. You see decaying, rotting, or mold around the window

Perhaps you can already see the signs of water damage in your home. If so, your new windows may need to be full-frame installed to remove the damaged sill and trim.
  1. You can feel a draft

If you’re not sure where the draft is coming from, holding a lit candle up to each window will help you locate the leak. In this case, installing new windows will help keep your air inside and reduce your energy bills.
  1. You want to reduce your energy bills

Even if you have functioning windows you will see energy savings if you invest in new windows. The latest technological advances, including triple glazing, inert gas filling, and more, have vastly improved modern windows’ insulating properties.
  1. You can hear noise from outside

As window installers, we at Thermo-Bilt have been in a lot of homes that have a high-traffic street just outside of the living room. Few people realize that the right windows can insulate you from sound, whether you’re hearing cars, trains, stores, or the school across the road on recess break.
  1. Your windows get stuck

If you find yourself fighting to get the window open or closed, something has shifted in your home or the window itself to bend it out of shape. Maybe the hinges are damaged, maybe water damage has swollen the sill, or maybe there’s some other problem. We’ll figure out what has gone wrong before we install your new windows.
  1. You live on the coast

In some areas, windows are just exposed to more wear and tear than in others. It’s not just about the storms the coast inevitably throws at your home, salty and humid air does damage all by itself. If you’re living on the coast, you may want to look at your windows from the outside of the home and see if there’s any damage.
  1. Your windows look out of place

Windows can make or break the style of a room, depending on what look you’re going for. Modern looks with old windows will seem cluttered, while historical restorations will need window styles to compliment them— if not, the look will be especially glaring from the outside.
  1. Your furniture or carpets are fading

Old windows don’t offer your furniture protection from UV rays, which can dull colours on any kind of fabric. If you’re developing an odd lightened spot on your carpet, it’s time to get new windows that can protect your home.
  1. Your window looks small

Over time, a succession of retrofit window installations can reduce the actual area of glass in your window, giving your home less natural light and reducing your view. A full-frame installation can restore your windows to their full size. Whatever your concerns with your current windows, at Thermo-Bilt Windows and Doors we’re ready to advise you on how to achieve the results you’re looking for. Contact us for a FREE quote!

Behind the Scenes: How Windows are Installed

Your windows are an important part of your home. They protect you from moisture, wind, and drastic temperatures during the winter and summer. It’s always a good idea to invest in higher quality materials, as improper methods can lead to rotting or drafts. From bay windows to awning, window installation comes in all shapes and forms. With such a wide variety of sizes, styles, and configurations, it’s often a mystery as to how they’re installed. We’re here to show you a behind-the-scenes look at a step by step guide to window installation:

Remove Trim, Casing, & Guide Track

Use a crowbar to remove the window trim and jamb extension (side tracks) from the perimeter of the old window. Then unscrew the window from the jamb and remove it. Go slowly, making sure you don’t break the glass during removal.

Prep/Repair New Window Opening

Once your window has been removed from the wall, check the window jamb for structural damage. If you come across any damage, you may want to call a professional since the jamb will have to be replaced before installing the new window. Now you’ll need to ensure that the rough opening can accommodate the new window installation. The opening should be 1/4” to 3/8” larger than the exterior dimensions of your new window.

Inspect & Replace Window Stop

A window stop is a piece of wood that can be found on the exterior side of the window jamb. Its purpose is to prevent the window from sliding out of the opening, as it physically stops the window from moving. Chances are your original stop will still be usable, but you may need to repair or replace it if it is damaged.

Dry Fit the New Window

The next step is to dry fit the new window into the opening so there are no issues with fit. If you’re struggling to make it work, make adjustments to the rough opening until it fits. If you’ve done it properly, the new window should fit snugly into the opening.

Install New Window

Window installation itself is often very simple once the previous steps are out of the way. First, you’ll need to run a bead of silicone on the inside edge of the window stop, then slide the window into place. Use a level on the top of the window then use cedar shims between the frame and jamb to get it level. Once it’s sitting right, there are two screws that go into each side of the window, then another one near the top and the last near the bottom.

Mount Trim Molding, Add Finishing Touches, Then Paint or Stain

You’re almost there! Now it’s time to pick a molding that suits your decor, then create a frame around the window. Measure the length of each piece, then cut the trim to the appropriate length. Using 45-degree angles cuts will ensure that your trim will fit together nicely, giving off that picture-frame look. Finally, attach the trim to the wall with finish nails. Fill any nail holes with wood putty, then paint or stain the trim any way you desire. Done! New windows have been replaced in your home. If your looking for professional window installation, look no further than Thermo-Bilt Windows & Doors. Contact us for high-quality windows that will leave your home looking brand new.

Ontario Green Rebate: Everything You Need to Know

The Ontario Green Rebate is a new rebate program that was recently announced by the Ontario government in 2018. It will be run through a provincial agency called the Green Ontario Fund. The rebate is aimed at residential homeowners who are interested in making green choices for their home. Homeowners can claim a variety of rebates through this program, including:
  • Up to $7,200 for new insulation
  • Up to $20,000 for installing an ENERGY STAR certified ground source heat pump (home geothermal) or up to $4,500 for repairing an existing heat pump
  • Up to $5,800 off air source heat pumps that are ENERGY STAR certified or meet program requirements
  • Up to $5,000 for replacement windows that meet program standards
  • $100 for air sealing your home.
This new rebate program comes after an August commitment to provide thousands of free smart thermostats to homeowners, a promise that the environment minister acknowledged. This has rolled out more slowly than the government would have liked. Only 1,000 of the devices have been installed to date.

Who is Eligible to Receive The Rebates?

To be eligible for the rebates, you must be an Ontario resident who lives in a detached home, townhouse or semi-detached home. If you rent, you must have the written permission of your landlord to receive the rebate. The major part of this program is that the renovations done to your home need to be done by contractors who meet the proper criteria, which includes:
  • They must have an HST registration number and either a Master Business Licence or Articles of Incorporation valid for at least two years.
  • $2 million dollars in liability insurance.
  • $1 million dollars in auto insurance.
  • A letter of clearance from WSIB.
To find out more about this program, if your contractor is qualified, and if you’re eligible to receive these rebates, visit

The Rebate that Keeps on Giving

Getting a rebate will help homeowners fund their next home renovation project. This is a great benefit of the program, but there are other reasons to get involved in the new Ontario Green Rebate. You’ll also be able to:
  • Reduce your heating and cooling costs.
  • Decrease your carbon footprint.
  • Increase your home’s resale value by upgrading to high-performance windows.
  • Upgrading your insulation can help you save 15 percent on heating and cooling costs.

The Green Ontario Fund & Ontario’s Pledge to Reduce Greenhouse Gas Emissions

The Green Ontario Fund is a not-for-profit provincial agency that invests proceeds from Ontario’s carbon market into climate change actions to help people and businesses reduce greenhouse gas emissions and use cleaner technology when powering their homes and workplaces. Ontario has pledged to cut greenhouse gas pollution to 15 percent by 2020, 37 percent by 2030 and 80 percent by 2050. The Ontario Green Rebate is a key part of the province’s Climate Change Action Plan and will help the province meet these targets. This not-for-profit agency takes consumer protection very seriously, which means that their agents will never come to your door without consent. To claim your rebate, you also need to ensure your contractor is qualified and screened, and they have signed up with – check before you begin your project.

Full Frame versus Retrofit Windows

Many people do not realize that regardless of which replacement window you choose, there are two different ways to install the window. It is essential for you to know the difference between full frame window installation and retrofit window installation to get the right install for your home.

Full Frame Window Installation

Full frame window installations require that the existing window and all of its supports are removed, including the trim and sill. The new window is then installed right into the framing of the home. The trim and sill are then replaced, and sometimes the internal trim. Full frame replacement may be preferred if there are issues with the exterior or interior wall near the window. Occasionally, the interior or exterior trim (or even the windowsill) can been damaged or infested with bugs or mould. This is one reason to go with vinyl in the future-- vinyl can’t rot and is more durable than traditional wooden window elements.

The Pros and Cons of Full Frame Window Installation

If your window is damaged, it’s much better to start with a blank slate and correct the underlying issue. Remember, professional window installers will always inspect and look out for structural or cosmetic issues in your home that might impact the performance of your new windows. New homes are less likely to need full frame replacements. But, even if it’s not required, you may want a full frame install because it gives you more choice in window materials and style. Full frame window installation is more expensive than a retrofit window installation. It takes more time and extra materials. You also need to be careful to match the trim and sill to the style and colour of the rest of your home.

Retrofit Windows

The alternative is retrofit window installation. Also called an insert or replacement window. This window installation method essentially means placing a slightly smaller window into your old window’s spot. The trim and sill remain unchanged.

The Pros and Cons of Retrofit Window Installation

If there are no problems with the existing window elements you can have a retrofit window installed. It takes less time and uses the same trim and sill. This can reduce your costs significantly. However, this installation method requires more glass area. This might reduce your view and limit how much light comes through the window. If installed poorly a retrofit window may not be level, may not be sealed correctly, or may be difficult to open. That’s why you should choose the professionals and expert team at Thermo-Bilt Windows and Doors. You can rest assured your windows are perfectly installed every time.    At Thermo-Bilt Windows and Doors, we always take the time to understand your concerns about window installation, aesthetic design, and the energy performance you want. Our knowledgeable staff knows what kind of window replacement you’ll need to get the look and results you’re aiming for.  Call (905) 752-3536 or contact us today for a free quote!

Can Window Installation Be Completed In Winter?

We’ve had our share of customers ask us if we can complete a window installation for them during the winter. It may be surprising, but almost without exception our answer is yes! In fact, there are many benefits to having your winter window installation completed.

The Off-Season

Every savvy shopper knows that purchasing something in the off season comes with all kinds of savings. For window installations, expect less delay in getting specialty windows ordered, delivered, and installed. Our schedule is much more open in the winter too, so we can better meet your needs for emergency installs, quick installs, or installs during busy hours.

Ease of Installation

With only one exception, window installations are done just as well in the winter as they are in the summer. Vinyl barely swells with heat or cold, meaning it is unaffected by the yearly change of season (especially compared to wood). Also, we use suitable caulking to ensure the seal on your windows is perfect, even in cold temperatures. Unfortunately, the only downside is caulking cannot be applied at temperatures below -20°C (even the cold-weather resistant kind won’t seal). At extreme cold temperatures, caulking becomes brittle instead of forming into a thick and flexible seal. However, you don’t need to worry because it rarely drops to such extreme temperatures in Ontario. Additionally, below-freezing temperatures are also a benefit for window installation. It’s much easier to detect leaks around your window in the winter, because any external air will form moisture droplets as it moves in. Furthermore, you can precisely pinpoint entryways for cold drafts, which helps ensure a tight seal for your new window during installation.

Energy Reductions

Many of our customers are looking to replace their windows because they want additional energy savings. If that’s the case, why wait? You save the most on your energy bill from new windows in the winter, so start reaping the benefits of your investment now.

Heat Loss

Most customers are generally worried about how much heat their home will lose if they choose to install their windows in the winter. At Thermo-Bilt, we are professional and respectful of your time and your home’s energy resources. We take all precautions to prevent any heat loss during a winter window installation. We install each window one at a time, by preparing new windows before we take the old one out. This limits how much time your home is exposed to cold air. We also place plastic coverings over an empty window to further protect your home from chill. Generally, we recommend that the door to whichever room we’re installing a window remains closed. You can pile towels at the base of the door to help insulate the rest of the home. Furthermore, while your home may lose some heat during the installation process, you’ll find it warms up a lot faster once your new windows are put in place. Why be uncomfortable throughout the winter when you can get a toasty warm house with new windows? Contact us for a free quote so you can enjoy the rest of the winter season in comfort.

How to Winterize Your Windows & Doors

Winter is here, along with it is an increase in your heating expenses. Are you looking for ways to keep your home warm this winter without spending a fortune? Take the time to check your home's windows and doors – a good place to start is your home’s main entry points.

Find Drafts in Your Home

Drafts are a killer on your home’s energy bill. If your home has drafty windows and doors then you’ll see a substantial increase in your energy bill every month. As cool air sneaks into your home, your furnace will be working twice as hard to keep your house warm, which can significantly reduce the life of your furnace. How can you determine if your home has drafts? Take a candle and place it near a window or door. If you see the flame dancing or flickering, it's likely a draft is getting through the window or door. If this occurs, you’ll need to do some extra work to prepare your windows and doors for the winter.

Block Drafts

Your local hardware store will have draft snakes to place at the bottom of your windows and doors. Draft snakes are effective in preventing warm air from escaping and cold air from entering your home. If you’re on a budget, try this do-it-yourself option instead: Roll up several old towels and tie elastics at each end to keep them in their tube form. This is an inexpensive but temporary way to stop drafts. The best way to keep your house warmer and save on your energy bill in the long-term is to replace your drafty and leaking windows and doors with new ones.

Check Your Caulking

Caulking helps maintain a tight seal around your windows and doors. Using caulk is a huge defence against cold air entering your home and warm air escaping. Unfortunately, over time even the best caulking eventually develops cracks and gaps. Luckily, it’s easy to seal up cracked caulk or gaps around your window’s seal. Depending on the severity of the problem you might need to remove the old caulking and replace it with a new one. However, if the caulking is in adequate condition with minimal damage, you can simply patch up any problem spots.

Plastic Film is an Affordable Fix

Many homeowners place plastic films over their windows. During the winter months, this protects against the cold and helps to maintain warmer indoor temperatures. Clear plastic film is a more affordable option since it can be found at most local hardware stores. It’s held in place using double-sided tape and doesn’t block your outdoor view (although you won’t be able to open your windows). However, plastic film should be used with caution. Natural Resources Canada points out that some people are sensitive to the plastic used in heat-shrink film. To prevent damage plastic film may not be the best option for households with small children or pets. For safety reasons, it should be kept away from strong heat sources.

Take The Screens Off

It’s also a good idea to remove your screens at the beginning of the winter months. This ensures your screens are protected from harsh winter weather and make them last longer. Furthermore, having them on hand will make them easier to clean when spring arrives. Make sure you store your screens in a warm and dry space until winter ends.

Keep Warm, Winterize Your Home

Protect your windows and doors this winter. You’ll find it easier to keep your home warm and cozy with these simple tips – which you’ll appreciate when you need a break from the cold. Contact Thermo-Bilt to get started on winterizing your home!

How To Choose The Best Windows For Your Home

Considering almost every room in your home has windows, you probably rarely think about the design options that are available to you. Need a change in your home? Your windows and doors may be the perfect place to start.

Identify Your Needs

First, when deciding on the best windows for your home, it is important to identify your needs. Start off by asking yourself these questions:
  •    Do you need windows that provide a lot of natural light?
  •    Do you have a beautiful view you would like to take in?
  •    Do you live somewhere cold and therefore need windows that insulate well?
  •    Do you open your windows often to let fresh air in?
  •    Do you care about your windows being purely functional or would you like to add some aesthetic value to your home as well?
Your answers to these questions will help you determine the best windows and doors for your home.

Consider your options

Once you recognize your needs, it can be overwhelming to wade through the mass amounts of options that will be available to you. Follow the guide below for a breakdown of some popular types of windows.

Bay Windows

If you have a beautiful view outside your home that you want to take in from the comfort of your living room, a bay window is a great option. Their large size allows for a tremendous amount of visibility and natural light. Bay windows also help create a cozy space to snuggle up and read a book while basking in the sunlight.

Awning Windows

Awning windows are a must have for anyone who enjoys letting fresh air into their home or who does not have central air. Awning windows have cranks that easily turn to open and close the window on a hinge. Another function of the awning window is that because they usually open along the top edge, they create an awning that will keep rain from getting into your home in the case that you accidentally leave them open during a storm.  


Skylights help you maximize your natural light intake during all hours of the day. Many people prefer adding skylights over additional windows because they allow extra light in without compromising wall space or privacy. That’s why they’re so popular in washrooms.

Entry Door Windows

Your front door is often the first thing people notice about your house so combining windows with your door is a great idea. Putting windows around your door can make the entry way look more visually appealing while also providing a clear view of the front yard, making it possible to see who is knocking on the door before you open it.

Energy Efficient Windows

No matter which design style you choose when it comes time to replace your old windows with a newer model, consider investing in energy efficient windows. There are many energy efficient options available now that will substantially reduce your utility bills each month. Speak with a professional today to start your journey to new windows and doors!

Winter windows to keep home warm.

The Best Winter Windows to Keep Your Home Warm

In the winter, the quality of your windows will make a huge impact on your heating, comfort, and energy bill. Instead of wrapping yourself up in heavy quilts, or turning up the furnace until your bill increases, invest in winter windows to keep you warm throughout the cold season. Here are our top priorities you should keep in mind when planning your winter window replacement.

Window Energy Efficiency

Your winter replacement windows should have a good energy efficiency rating. According to Canadian Energy Star ratings, that means aiming for the lowest number possible. Furthermore, you should also invest in  R-rated windows, which are intended for single-family homes. After educating yourself on the vast ratings consider glazing and filling. At a minimum, you should invest in double-glazed windows. This two-layer protection keeps heat from escaping through your windows. Additionally, there are higher quality glazings available that function in different ways, which may benefit your home – depending on your needs. Modern windows are filled with inert gases ( argon or krypton) which increase their insulating properties. Those living in colder climates of Canada may prefer using krypton gas, it’s more expensive than argon,  but it’s insulating properties are better concentrated.

Protect Windows from Humidity

Your winter window replacements need to withstand humidity. The contrast between warm air inside and the cool exterior air drains your home of moisture, which leaves many people feeling dry and uncomfortable. Many homeowners choose to compensate with a humidifier as the most effective solution to dry, dull air. Unfortunately, if you have poor quality windows and frames it will react poorly to increased humidity. The window’s surface wears down and the frame can harbor mold. However, you don’t have to sacrifice your comfort. Instead, look for more energy efficient windows that can tolerate higher humidity levels without developing frost or wearing down the material. Furthermore, take fitted vinyl windows into consideration. They provide additional protection against humidity, such as accelerated mold growth which usually occurs on wooden surfaces.

Don’t Forget Cold Drafts

Older windows don't function as well as new windows; they allow drafts to seep through, significantly reducing your home’s energy efficiency making your home chilly in the winter. Do a quick test to check if your windows let in drafts before the weather gets too cold. Simply place a lit candle near the window and see if it flickers. If it does, small currents of air are moving in or out of your home. This means your window isn't sealed off properly and you'll need to replace the window. Don't worry, at Thermo-Bilt you can trust us to do the job. Our team of professionals install window replacements tightly and securely the first time. We can also apply industry grade weather stripping, to seal up your window and stop drafts from forming.

Cost Matters

Despite what others say, you don’t have to spend a fortune to obtain excellent quality windows. Our large collection of winter window products will meet your needs while considering your budget. We will personally walk you through each window and explain their function. Before making a decision, take advantage of our FREE quote on replacement windows.

Energy efficient windows ratings.

Energy Efficient Windows: A Comprehensive Guide

How do you know which energy rating is the best? What do the ratings mean? In Canada, energy-efficient windows are rated based on their U-Factor, Solar Heat Gain Coefficient, and air leakage grading. Generally, the common rule of thumb is the higher the number of the energy rating, the higher the efficiency of the window. You may also see a letter rating on the windows, which is the North American Fenestration Standard. This indicates which type of building a window is best for; R is for single-family residential buildings. LC is for low rise, CW is for mid-rise, and AW is for a high-rise. For the Canadian rating system, there is a lot of technical information included. Therefore, you'll want to make sure you do your research and look into it the best window that meets your needs. We've made it easy to understand. Simply follow our the rating explanations below:

What is U-Factor?

U-Factor is always examined in energy ratings. It is the rate of heat transfer from the product's warm area to a cold area. Usually, you want your window to transfer this heat slowly, so you’re not losing heat to the outdoor environment. The lower the U-factor number, the more energy-efficient your windows will be.

What is the Solar Heat Gain Coefficient?

This ratio describes how much of the sun’s heat passes through a window, warming up the interior behind the window. The higher the number, the more solar heat the window provides. In a passive home, you would want a high solar heat gain coefficient to help the home stay warm in the winter.

Air Leakage

This factor is more straightforward. Air Leakage measures how much air leaks out of a window. For obvious reasons, you don’t want air to leak through your window, as it lets your heat (or air conditioning) escape into the environment. If your windows have high air leakage, it’s time to get them replaced.

What is R-value?

The R-value factor is not a concern under the energy rating, but it’s often used as an indication of energy efficiency in windows for industry experts. It measures how much resistance there is to heat transfer in the glass, or the amount of heat retained by the window. The higher the number the better the glass, indicating high heat has trouble passing through the window.

What is the difference between Argon and Krypton gas?

Energy efficient windows are filled with either argon or krypton, both are non-toxic gases to help insulate the panes. While argon is the cheaper gas, krypton is a better insulator. Sometimes the gases are blended so the windows can meet specific energy standards, while still being easy on your wallet.

What are Low E-coatings?

These glazings are applied onto the glass to block additional heat transfer. The three most common choices are Low-E 180 (a standard application), Double Low-E (which provides better efficiency), and Low-E 366 (which is meant for windows with intense sun exposure).

What is the ENERGY STAR® Certification Program?

Administered by Natural Resources Canada, this certification is meant to help consumers identify products which are energy efficient. Every year, ENERGY STAR® gives out accolades to the products with the best energy efficiency. Do you have more questions? We can answer all your inquiries about energy efficient windows – from glazing, ratings, and different window types to fit your home's needs. Contact us today for a FREE quote!
