Who doesn’t want thin window frames to enjoy unobstructed views and significantly more light?! Window frame thickness is probably one of the first things anyone takes into account when choosing new windows – it matters for performance, energy efficiency, and aesthetics.

So, if you want to discover the standard frame thickness for windows made of different materials, keep reading!

Key Takeaways

• The standard window frame thickness varies depending on the material: uPVC (70-100 mm), aluminum (50-75 mm), and wood (50-120 mm).
• Magic frames are among the slimmest window frames in Canada – they feature a combination of aluminum, steel, and vinyl, thus not compromising on energy efficiency and durability.

Standard Thickness of Window Frames

Different frame materials have different standard thicknesses. You should consider this aspect because it also affects the performance of your windows, not only their aesthetics. Read on to discover more details about the thickness of each frame material.

uPVC Windows

uPVC window frames have a thickness of approximately 2.8-3.9 inches (70-100 mm) – typically wider than any other windows.

These frames are popular due to their energy efficiency and low maintenance requirements. However, they’re among the widest window frames on the market. How so? Well, vinyl is prone to bowing and warping in extreme weather conditions – that’s a downside! Therefore, manufacturers improve the material’s strength and durability by using thicker vinyl walls.

Furthermore, the thickness of the window frames made of vinyl depends on your glazing choice: double glazing and triple glazing have thicker frames.

Aluminum Windows

Aluminum window frames are usually thinner than uPVC windows. They measure between 2 and 3 inches (50-75 mm) thick – this is one of the reasons people favor aluminum above other frames, as they look more stylish!

In addition, aluminum windows are extremely durable, which is why thin aluminum frames can withstand larger glazing areas and thicker glass panes.

On the other hand, aluminum doesn’t have a good thermal performance. This means you’ll have to deal with high energy bills – the windows won’t do their job well at maintaining a steady indoor temperature.

Wood Windows

Wooden window frames generally have a thickness between 2 and 4.7 inches (50 and 120 mm), depending on the design you choose.

They are energy efficient and incomparable to other window frames in terms of their timeless aesthetic. On the other hand, wood windows require a lot of maintenance – it can be time-consuming and sometimes become overwhelming if you’ve never maintained wooden frames.

Fiberglass Windows

Fiberglass windows are usually as thin as aluminum windows or slightly thicker, depending on your glazing choices. It goes without saying that they’re thinner than vinyl windows.

Fiberglass windows are energy-efficient and durable, although they cost more than other windows.

Magic’s Hybrid Fusion Frame

Without a doubt, Magic’s Hybrid Fusion Frame is the best choice for Canadian homes. We’ve considered all the advantages and disadvantages of other window frame materials on the market and have combined them so they complemented each other. The result is a highly energy-efficient, strong, and thin window frame material!

Our frames have an aluminum-steel skeleton, which is wrapped in vinyl. This design keeps the aluminum intact during extreme weather conditions – this guarantees your windows’ high energy efficiency and durability. Not to mention that the superior strength of our frame material allows us to manufacture thin frames that can hold large glazing areas.

Factors Influencing Frame Thickness

The thickness of the window frame is influenced by several factors (besides the frame material):

• The size of the glazing area and the window size
• The glass thickness, which is different in single-, double-, or triple-pane glass
• The type of window (casement windows may have a thicker frame than sliding windows, for example)
• Structural requirements
• Aesthetic considerations
• Casing and trim – these don’t affect the size of the frame directly, but they can make your windows appear thicker or slimmer, depending on the type of casing or trim you choose.

Impact of Frame Thickness on Energy Efficiency

The thickness of window frames significantly influences their energy efficiency – this will leave a mark on both how comfortable you feel in your home and your energy bills.

Thicker window frames usually mean better insulation. They can help reduce heat loss and improve the overall thermal performance of the windows. This can lead to substantial energy savings, especially if you live in climates with extreme temperatures.

However, having energy-efficient windows with slim window frames is not impossible – that is, if you choose Magic windows. As mentioned earlier, our frames are among the slimmest on the market and still ensure superior insulation and durability, reaching a lifespan of 40 years.

Benefits of Slim Window Frames

Standard thicker frames can indeed be more energy-efficient and withstand the weight of larger windows. However, when you have the possibility to install a slim, energy-efficient, and durable window frame, why not go for it? The benefits of slimmer window frames cannot be overstated:

• More natural light, which improves our mood, boosts our energy levels, and helps us stay more creative. It also positively affects our circadian rhythms.
• Larger glazing area – after all, who doesn’t want more extensive, unobstructed views? In addition, a larger glazing area equals better ventilation when the window is open.
• A modern design – bulky frames can make the room feel smaller and confined; slimmer frames, on the other hand, can improve home design, making the room feel brighter and larger; thin frames can even increase property value if made from high-quality materials like those used for Magic’s Hybrid Fusion Frame.

Custom vs. Standard Window Sizes

If you want custom windows, it’s worth noting that they’re usually more expensive than standard windows. The latter are readily available and easier and quicker to install so, automatically, they’re also more budget-friendly.

If you do have a uniquely shaped rough opening where you want to install a window or you live in an older building, which may require a more complex window replacement project, you’ll have to find window manufacturers who can accommodate these design needs.

Let’s say you want to install a small, hexagonal window. In this case, you’ll have to find a manufacturer that provides slim window frames made from energy-efficient materials. Installing a standard vinyl frame isn’t a good option because there will be little to no glazing area left.

Or here’s another example – you want to install a transom window above the front door and don’t want it to have a standard rectangular shape. In this case, there are two things to consider:

• the frame thickness, because transom windows aren’t that large, so you want your frames as thin as possible;
• the window manufacturer’s availability for custom-shaped windows.

Frequently Asked Questions

How thick are windows in Canada?

Windows in Canada have different thicknesses, ranging from 2 to 4.7 inches (50 to 120 mm), depending on the frame material, glazing options, and structural needs.

What is the thickness of a window frame?

The standard thicknesses for window frame materials are as follows: uPVC frames are generally 2.8-3.9 inches (70-100 mm), aluminum frames range from 2 to 3 inches (50 and 75 mm), and wooden frames typically measure 2 and 4.7 inches (50 and 120 mm). The slimmest window frames are Magic’s Hybrid Fusion Frames.

How does frame thickness affect energy efficiency?

Frame thickness significantly impacts energy efficiency. Thicker frames usually enhance insulation, reducing heat loss and subsequently lowering energy costs. However, some composite frame materials, such as Magic’s Hybrid Fusion Frame, can be used for slim frames without compromising on energy efficiency.

What are the benefits of using custom window frames?

Custom window frames (which can also be personalized in terms of thickness) are excellent for uniquely shaped windows or older buildings. However, they’re more expensive and require longer delivery times.

What are the benefits of slim window frames?

If made from durable and energy-efficient materials, slim window frames can help keep indoor temperatures steady, allow more natural light in, increase property value, and enhance the design of your home.
