What is a Casement Window?
Casement windows open outwards on a hinge. They use a crank to open. When closed, they press into the frame, making a tight seal.
They can be single or double panels. Or they can be paired with fixed glass for wider views. This makes them different from other types of windows.
They open fully for better airflow and views. Their design catches breezes better than sliding windows. This makes them great for ventilation.
One big benefit is their tight seal. The U-factors vary by material. Vinyl is around 0.30, wood is near 0.28, and fibreglass is roughly 0.26. Aluminium is closer to 0.35.
They have multi-point locks and durable hinges. You can choose from many finishes. These features make them secure and customizable.
Choosing the frame affects cost and upkeep. Vinyl is easy to maintain but costs a bit. Wood is classic but needs more care. Fibreglass is durable and well-insulated but costs more upfront.
Maintenance is simple. Just lubricate hinges and check the crank now and then. Cleaning is easy on reachable installations. But, parts can wear out and need fixing.
But, there are downsides. They need space to open and can be pricey. They also need clear space outside to work well.
They suit homes that value tight seals, clear views, and strong ventilation. They’re a good choice for energy-saving homes in Ontario and the GTA. They work best where they can open outwards.

What is a Sash Window?
Sash windows are frames that slide up and down. They fit well in both old and new homes. They can be single-hung or double-hung, with each sash moving on its own.
These windows are special because you can control how much air gets in. Opening the top sash lets warm air out. Then, opening the bottom sash lets cool air in.
Double-hung windows are better at moving air around because both sashes can open. This is different from single-hung windows, which only open from the bottom.
Cleaning and fixing sash windows is easy. Modern ones can tilt inward or have sashes that come out. This makes cleaning on high floors simpler. But, parts like balances and locks need to be checked now and then.
Now, let’s talk about how well sash windows keep heat in. They’re not as good as some other windows at keeping heat in. But, you can make them better with double glazing and special coatings.
It’s also important to install them right and use weather-stripping. This helps keep cold air out and warm air in.
Sash windows are also great for looks. They fit well with old homes and add a classic feel. You can choose from materials like vinyl or wood, and they come with modern parts to last longer.
But, there are some downsides. Over time, sash windows can let air in if the seals wear out. Dirt can also make them hard to slide. Cleaning the outside can be tough without the right design.
So, it’s good to check them often and fix any problems quickly. This keeps them working well.
For homes in Canada, sash windows are a good choice. They’re perfect for old houses, restorations, and places that value history. Double-hung models are best if you want easy cleaning and flexible air flow.

Compare Energy Efficiency Between Casement and Sash Windows: Comparison Table
We have a quick look at how casement and sash windows compare in energy efficiency. The table below shows U-factor ranges, air leakage, solar heat gain control, and upgrade options for common materials in Canada.
| Feature | Casement Windows | Sash Windows |
|---|---|---|
| Typical U-factor (vinyl) | ~0.30 — tight compression seals reduce heat transfer | ~0.32 — tends to be slightly higher without upgraded seals |
| Typical U-factor (wood) | ~0.28 — strong baseline performance with good installation | ~0.30 — can match casement when fitted with modern glazing |
| Typical U-factor (fibreglass) | ~0.26 — one of the best baseline U-factors available | ~0.28 — improved with careful weather-stripping |
| Typical U-factor (aluminium) | ~0.35 — requires thermal breaks to perform well | ~0.36 — often needs better glazing to compete |
| Air leakage | Low — sash presses into frame for superior airtightness | Moderate — relies on weather-stripping and maintenance |
| SHGC / Solar gain control | Low-E coatings and insulated glass reduce unwanted gain | Same upgrade path available to control solar heat gain |
| Insulation upgrades | Double- or triple-pane IGUs, low-E, argon/krypton gas fills boost performance | Double- or triple-pane IGUs and high-quality seals improve results |
| Ventilation | Excellent — casements open fully for strong airflow | Controlled — top and bottom openings allow staged ventilation |
| Canadian climate notes | Strong in Ontario/GTA winters; tight seals cut heating demand | Performs well if upgraded; requires careful installation to limit drafts |
| Installation sensitivity | Less forgiving — needs precise fitting to meet rated U-factor | More sensitive — weather-stripping and alignment critical for performance |
| Typical practical advantage | Baseline energy gains due to compression sealing and frame choices | Historic character and sash window advantages when modernised |
When picking windows for Canadian homes, a detailed energy efficiency comparison is key. Casement windows often lead in cold climates with lower U-factors and less drafts. Sash windows shine when homeowners choose top-notch glazing and seal them well.
Remember, the quality of the manufacturer, the material, and the installer’s skill matter a lot. Both types can get the same insulation upgrades. So, think about looks, ventilation, and upkeep needs when deciding.
Cost Analysis: Comparison Table
We have a detailed cost comparison for casement vs sash windows. It covers the cost of buying, installing, and long-term costs. This helps homeowners think about the initial cost and future savings and maintenance.
Initial costs depend on the material and mechanism. Vinyl casement windows are often cheaper than wood or fibreglass. But, casement windows need crank and hinge hardware, which increases the cost. Sash windows can be affordable if they are single-hung. Double-hung sash units, on the other hand, cost more because of the extra hardware.
Installation complexity affects the labour cost. Casement units need precise sealing and alignment of hinges and cranks. Custom sizes or heavy frames can increase labour costs. Sash windows, like double-hung with tilt-in sashes, require careful balancing and sealing. This can make installation take longer.
Long-term energy costs can change the value of each option. Casement windows often seal better and can save on heating bills in Ontario. Sash windows might be cheaper at first but could cost more for energy unless they have double- or triple-glazing and low-E coatings.
Maintenance also affects long-term costs. Casement hardware needs regular servicing and sometimes part replacement. Sash systems need attention to balances, tracks, and weather-stripping to keep working well.
| Cost Element | Casement | Sash |
|---|---|---|
| Average purchase cost (per window) | $400–$1,200 depending on vinyl, wood or fibreglass and casement window style | $300–$1,000; single-hung at lower end, double-hung higher due to extra hardware |
| Typical installation labour | Moderate to high: precise sealing and hinge/crank alignment increases time | Moderate: double-hung with tilt-in sashes may add installation time |
| Long-term energy cost impact | Lower in cold climates due to airtight seals; potentially saves energy over 10–15 years | Potentially higher unless upgraded glazing; energy upgrades increase upfront cost |
| Maintenance & repair | Periodic crank and hinge maintenance; mechanical repairs possible | Balances, tracks and weather-stripping upkeep; periodic re-sealing |
| Resale & aesthetic value | Boosts modern energy credentials; complements contemporary homes | Adds heritage appeal in traditional homes; retains period character |
| Local supply impact | Using local manufacturers like Total Home Windows & Doors can reduce lead times and installation costs | Local sourcing also reduces delays and ensures warranty service for sash window functionality |
| Typical payback horizon | Shorter when energy savings are high in colder regions; often 8–15 years | Longer unless energy upgrades are included; payback varies with glazing choices |
We recommend budgeting for both the cost of buying and installing. Also, add a contingency for upgrades that improve thermal performance. A detailed cost comparison helps choose between casement and sash windows based on your goals. Whether you’re focused on saving money or on long-term energy savings.
Casement vs Sash Windows: What’s Best for Your Home?
When choosing between casement and sash windows, think about energy efficiency, ventilation, looks, upkeep, cost, and space. In Ontario and the Greater Toronto Area, keeping warm in winter is key. Casement windows are great because they seal tight, lock well, and open fully. This helps keep the cold out and saves on heating.
Sash windows are perfect if you want a classic look and easy cleaning. They’re great for homes with a traditional style and limited space. This is because they open inward, unlike casements.
It’s smart to mix both types. Put casements in rooms that need fresh air, like kitchens and living areas. Use sash windows in bedrooms or where the style fits. This way, you get the best of both worlds.
Make sure to pick a trusted local maker and installer. Total Home Windows & Doors has been making windows in the GTA for 15 years. They can help you choose and install the right windows for Canada’s weather. Many homeowners choose casements for better ventilation and energy saving. But sash windows might be better if you like the old-fashioned look or want to save money upfront.
