What is a Casement Window?
Casement windows open outwards with a crank or modern hardware. They give clear views and let in breezes. This makes rooms feel fresher.
These windows are great for ventilation and energy saving. They have wide glass for better views. Many also have locks for safety and easy cleaning features.
In places needing constant air flow, casements are better than many others. They seal well, which helps save energy. This makes them a top choice for kitchens and living rooms.
But, casements need space to open. They’re not good for tight spots. They also need occasional upkeep, but some models are easier to maintain.
Big windows need special parts to open easily. Sometimes, two casements work better together. But, they can get damaged in busy areas if not placed right.
When picking windows, look at U-factor, SHGC, and air leakage. For Canada, choose ENERGY STAR-rated ones. They keep your home warm or cool better.
Casements are best for areas needing lots of air and views. They’re perfect for modern homes. They’re a better choice than single hung windows for keeping your home cool and airy.
| Feature | Casement Strength | Practical Note |
|---|---|---|
| Ventilation | Maximum — full sash opens | Ideal for rooms needing strong cross-ventilation |
| Energy efficiency | High — compression seals lower leakage | Often better U-factor than single hung units |
| Cleaning and maintenance | Easy — many clean from inside | Crank-less Parallex hardware reduces upkeep |
| Security | Strong — multi-point locks | Single-sash design increases visibility and safety |
| Site limitations | Requires exterior clearance | Not suited to narrow walkways or crowded exteriors |
| Best use | Rooms needing views and airflow | Kitchens, living rooms, modern renovations |

What is a Single Hung Window?
Single hung windows have two sashes. Only the bottom sash moves up and down. The top sash stays fixed. This design makes cleaning the glass easy from inside.
These windows save space. They don’t need room to swing, making them great for tight spots.
They are also affordable. This is because they have a simple design with fewer parts.
They look good in many homes. They fit well in both old and new houses.
Cleaning is easy. You can clean the glass without using a ladder. Some models make this even simpler.
They meet some building codes. This is good for bedrooms and basements. But, double-hung windows offer more air flow.
They might not let in as much air. This is because only the bottom sash moves. Casement windows can let in more air.
Older models might have thicker frames. This can block some of the view. Newer models are thinner, letting in more light.
They need regular checks. This keeps them working well for a long time.
They are good for saving money. They work well in places where other windows won’t fit.
Before buying, ask for energy details. Vinyl frames with good insulation are a good choice for Canada’s weather.

Compare Energy Efficiency Between Casement Windows and Single Hung Windows: Comparison Table
We look at important energy efficiency metrics: U-factor for keeping warm, SHGC for blocking sun, Visible Transmittance for light, and air leakage for tightness. It’s best to choose ENERGY STAR windows and consider local needs. For example, triple-pane for cold areas and moisture-resistant for wet places.
Here’s a quick guide on casement vs single hung windows. Always ask for test data on U-factor and air leakage. Good vinyl frames and modern glass units can make both types similar.
| Metric | Casement Windows | Single Hung Windows |
|---|---|---|
| Typical U-factor | Lower U-factor on average due to tighter seals; performs well with double or triple glazing and gas fills. | Moderate U-factor unless upgraded to premium IGUs; can match casement with triple glazing and quality frames. |
| SHGC | Selectable via glass choice; pair with Low-E glass to control solar heat gain in summer. | Similar adjustable; choosing Low-E glass and proper SHGC values helps reduce unwanted heat. |
| Air Leakage | Tighter air leakage ratings thanks to compression or bulb seals and sash pressure; ideal for heat retention in cold climates. | Higher air leakage at the sash interface; ask for tested air leakage values and reinforced locks to improve performance. |
| Visible Transmittance (VT) | High VT available with Low-E coatings that balance light and thermal control. | Comparable VT options; glass choice determines daylight without sacrificing energy efficiency. |
| Best glass/frame practice | Combine Low-E glass, argon/krypton fills, warm-edge spacers and quality hardware to keep seals intact. | Use high-performance vinyl frames, double/triple-pane IGUs, and tested seals to approach casement performance. |
| Regional recommendation | Preferable for Northern Canada: casement with triple glazing, gas fills and ENERGY STAR certification. | Suitable when upgraded for the climate; cost-effective for moderate climates if sealed and tested. |
In rainy or coastal areas, choose industrial-grade seals and corrosion-resistant hardware for both. For hot summers, use Low-E glass and SHGC values that block heat but let in light.

Cost Analysis: Comparison Table
We examine the main cost factors for casement vs single hung windows. Material choices like vinyl, wood, or aluminum set the base price. Glazing options, such as single, double, or triple pane, affect material costs and energy efficiency.
Hardware upgrades, like multi-point locks or crank-less systems, increase the initial cost. Installation costs vary based on unit size, complexity, and local labour and permit rates.
We list typical profiles for comparison. Single hung windows are often the most affordable due to simpler mechanisms. They are quicker to install, which lowers labour costs.
Casement windows usually cost more because of their crank hardware and tighter seals. Better hardware and weatherproofing add to the cost. Installers may need to assess exterior clearance, which can increase the total price.
We highlight other factors in cost analysis. Upgrading to triple-pane or argon-filled glass increases material costs but may reduce heating bills. Premium frames, like fusion-welded vinyl, add upfront expense but improve durability and performance.
Complex projects, like bay or bow combinations, increase labour and permit costs. It’s important to consider these factors when comparing quotes.
We suggest practical steps for comparing quotes. Ask Total Home Windows & Doors for detailed proposals. Their experience in the GTA helps tailor options to your budget and energy goals. Get multiple quotes and check what each includes to avoid hidden costs.

Casement Windows vs Single Hung Windows: What’s Best for Your Home?
Choosing the right windows for your home is simple. Match the type of window to your needs, like ventilation and energy efficiency. For cold Canadian winters, casement windows are best. They have special glass and gas that keeps the cold out.
In hot places, casement windows also help keep the heat out. They are sealed tight and have special glass that blocks heat. Single hung windows are good for tight spaces because they don’t swing out.
They save space and are cheaper to start with. But, upgrading the materials and glass can make them better over time. Casement windows are great for rooms where you want to see outside and get fresh air.
Coastal and rainy areas need windows that don’t let water in. Both casement and single hung windows can be made to last long if they are well-made and installed right. Always get a pro to install your windows.
They make sure your windows work as they should. For casement windows, keep the crank mechanism clean. For single hung, clean the tracks and balances. This makes your windows last longer.
