Buying replacement windows for your home can be stressful.
Not only do you have to choose between various styles, shapes, and sizes, but you also have to consider performance, energy efficiency rating, comfort, and overall quality.
The number of glass panes in a window affects many of these variables. As a trusted Canadian manufacturer of windows and doors, we’ll explain the differences between single-pane vs. double-pane windows to help you understand why one of these options is much preferable to the other.
Let’s dive in!
Comparison Highlights
→ Single-pane windows cost is more affordable than double-pane windows cost
→ Double-pane windows improve insulation and reduce condensation
→ Double-pane windows increase property value
→ Double-pane windows can reduce heating and cooling costs by 21-31%
→ Single-pane windows are best for homes in mild-climate regions
Single-Pane Windows Pros and Cons
Single-pane windows are made with a single sheet of glass.
Pros:
This type of window is typically more affordable, which makes it a favourite of property owners on strict budgets. Single-pane windows are also lighter in weight since they use less glass than double-pane windows. This feature makes them easier to install, which could help you reduce labour costs.
Cons:
Only having one pane of glass means their insulation and ability to regulate temperatures during harsh weather conditions is not as effective compared to double-pane windows. This lack of insulation can make single-pane windows prone to condensation, leading to moisture-related problems such as mould and mildew.
These windows provide little soundproofing, allowing external noises to penetrate easily.
When comparing single-pane vs. double-pane windows as it pertains to price, it’s important to know that a lower initial price with the former will end up being offset by higher energy bills down the road as a result of its poor energy-efficient design.
Are Single-Pane Windows Still in Use?
Yes, single-pane windows are still in use. However, homeowners who choose this style over multi-pane windows are likely motivated by cost rather than overall performance. Single-pane windows are more suitable in areas with mild climates (unlike Canada).
Double-Pane Windows Pros and Cons
Also known as dual-pane windows, double-pane windows contain two layers of glass with a sealed space in between, acting as a thermal barrier.
Pros:
The design of windows with two panes significantly improves insulation, reducing heat transfer and enhancing energy efficiency. This feature also lends to better temperature regulation, a reduction in condensation, and better sound insulation.
In fact, ENERGY STAR, a rating system backed by North American governments to assess energy efficiency on consumer products, estimates that double-pane glass windows can reduce your cooling and heating costs by 21% to 31%.
Multi-pane options, whether it be double or triple pane windows, often have higher resale values. Potential buyers appreciate the long-term cost savings and comfort associated with these windows.
Cons:
The cost of a double pane window is typically more expensive than a single pane window. However, many homeowners find that the long-term energy savings justify the initial investment.
Some other downsides to multi-pane windows are they can be prone to seal degradation over time, making repairs more difficult. The best way to mitigate this is through regular maintenance and quality installation.

Single-Pane Windows vs. Double-Pane Windows: Making Your Choice
So, which window glass option is the right choice for you? When weighing your options, there are a few factors you should consider.
The first thing to determine is your budget. While double-pane windows cost more, they do offer more benefits in terms of energy efficiency and insulation. Can you afford the steeper sticker price in exchange for the long-term benefits?
You should also consider your living conditions. If you live in an area where extreme weather is expected, installing double-pane windows will give you your money’s worth. Conversely, if you are on a stricter budget and live in an area with a milder climate, single-pane might be the way to go.
Single-Pane Windows
Pros:
→ Lower initial cost
→ Easier to install
Cons:
→ Less energy efficient
→ Easily broken
→ Poor soundproofing
Double-Pane Windows
Pros:
→ Great energy efficiency
→ Improved soundproofing
→ Better break resistance
→ Long-term energy savings
Cons:
→ More expensive upfront
→ Harder to install
Can You Replace Single-Pane Windows With Double-Pane Windows?
Yes, you can and it is highly recommended. Upgrading to double-pane windows helps “future-proof” your home and ensures greater energy savings in the long term.
If your home has single-pane windows and you’re looking to make the change, don’t let the initial upfront cost scare you away. The Canadian government offers several rebates and grant programs for homeowners and business owners that help offset the cost of energy-efficient replacement windows.
It’s important to ensure you pick quality windows when you begin the replacement process. Poorly spaced glass, bad sealing, and other defects can impact your energy savings as well as the lifespan of the windows themselves. This starts with the manufacturer you choose to work with!
