When choosing windows, one of the most important things homeowners have to decide is what window frame material to choose. Once they pick it, half of the problem is solved! All that’s left to do is choose glazing options (which are just as important nonetheless)!
Needless to say, carefully assessing all the types of window frames is the key to making sure that the investment is worth it and that the windows will successfully withstand the weather conditions in your region!
Because we know how overwhelming it feels to assess the pros and cons of all window frame materials on the market, we’ve included everything you need to know about them in this article.
Key Takeaways
- Window frames are usually made of vinyl, wood, fiberglass, steel, wood-clad, and composite materials.
- Vinyl, fiberglass, wood, and composite materials are the most energy-efficient. Aluminum and steel excel at durability, while wood windows take the lead in terms of aesthetics, although they require the most maintenance.
- The most budget-friendly frame materials are vinyl and aluminum, although they have disadvantages that can lead to costly repairs or high energy bills. Composite materials like Magic‘s Hybrid Fusion Frame are usually favored above others due to their durability, strength, energy efficiency, low maintenance, and customizability options.
- Choosing the right window frame requires consideration of climate, budget, and maintenance needs, as each material performs differently under various conditions.
1. Vinyl Window Frames
Vinyl window frames are made of a synthetic polymer called polyvinyl chloride (PVC), which is a combination of different pigments, plasticizers, and chemicals.
Without a doubt, vinyl is the most popular window frame material nowadays. First, it is more affordable than other materials – one vinyl window costs between $300 and $900. Secondly, it’s highly energy efficient and weather-resistant; this material has low thermal conductivity, which is why vinyl windows provide excellent insulation. Thirdly, it’s low maintenance; you don’t need to paint or sand it, as well as worry about cracks, rot, or rust.
Vinyl frames typically last 20 years or more, depending on the climate of your region. And this takes us to vinyl’s major structural flaw – it doesn’t do well in extreme weather conditions. Vinyl lacks the strength and rigidity of other materials like aluminum, so it’s susceptible to expansion and contraction in heat and cold, as well as wear and tear. Another thing to consider before buying vinyl window frames is that they’re bulkier than others, which is caused particularly by their lack of strength.
| Vinyl window frames | |
| Pros | Cons |
| Affordability
Energy efficiency Low maintenance Weather resistance |
Lack of strength
Bulky frames Susceptible to expansion and contraction Color limitations (dark frames are at a higher risk of fading) |
2. Wood Window Frames
Unquestionably, wood frames, with their timeless appeal, take the lead in terms of aesthetics, as they guarantee a classic, natural look. These window frames are usually made of pine, mahogany, or oak.
Wood is an excellent insulator, which makes it the perfect material for energy-efficient windows that can help homeowners save on energy bills. Wood also has superior soundproofing properties, which can be a decisive factor for those living in noisy neighborhoods. Not to mention that wood is probably the most eco-friendly frame material out there.
Another advantage of wooden window frames is that they’re incredibly durable. They can reach a lifespan of 50 years. This being said, wood window frames also require regular maintenance or, in other words, much more maintenance than any other window frame materials. If they’re not properly maintained, they definitely won’t last that long because wood is prone to mold growth and rot. They can also warp, crack, and swell. Plus, wood can become infested with various insects.
Therefore, you’ll have to:
- Clean wood windows at least twice a year.
- Inspect them regularly for cracks, moisture, and pest damage.
- Repaint them every 3-5 years (depending on how frequently they’re used and the weather in your region).
- Re-stain them every 1-2 years.
Another disadvantage of wood windows is their cost is relatively high compared to other frame materials. One wood window can cost between $400 and $2,500. However, the longevity and beauty they offer often justify the initial expense.

High maintenance
Vulnerable to mold growth, rot, and pest damage Vulnerable to cracking and warping caused by moisture and heat Higher cost |
3. Wood-Clad Window Frames
Wood-clad windows are basically wood windows, except that they have cladding (usually made of fiberglass, vinyl, or aluminum) that protects the frame – but it’s only added on the exterior. Inside your house, the wood is fully exposed.
Wood-clad windows are strong, durable, and energy-efficient. They require minimal maintenance and won’t warp, fade, or rot on the exterior. For the interior parts of the frame, where the wood is exposed, you’ll have to schedule a regular wood window maintenance routine. You’ll also have to check them regularly for moisture damage or rot, like with any other wood window.
Wood-clad windows are relatively expensive. One clad window costs between $500 and $2,000+, depending on what material is chosen for the protective layer.
| Wood-clad window frames | |
| Pros | Cons |
| Energy efficiency
Strength and longevity Soundproofing properties Eco-friendliness Resistance to the elements |
High maintenance on the interior
Vulnerable to mold growth, rot, and pest damage Higher cost |
4. Aluminum Window Frames
Aluminum window frames are especially popular in modern architectural designs due to their sleek, narrow profiles that maximize glazing areas, enhance outdoor views, and reduce visual distractions. They are also low-maintenance.
However, the biggest advantage of aluminum frames is their durability. Although lightweight, aluminum is incredibly strong and can withstand the harshest weather conditions. In addition, their strength allows homeowners to install large windows; there’s no risk for the frames to warp or crack under the heavy glass.
Last but not least, aluminum is a relatively affordable material – one aluminum window costs, on average, $590.
Nonetheless, like any other frame material on the market, aluminum has some drawbacks, particularly in terms of thermal insulation. Aluminum has a high thermal conductivity. This means that heat and cold pass quickly through aluminum frames, so you’ll likely spend a lot on energy bills if you live in a region with hot summers and cold winters. This also makes them susceptible to condensation. Plus, aluminum is prone to corrosion, especially in coastal areas.

| Pros | Cons |
| Strength and durability
Low-maintenance Lightweight Affordability Eco-friendliness Thin frames |
High thermal conductivity
Prone to corrosion Prone to condensation |
5. Fiberglass Window Frames
Fiberglass window frames are made of glass fibers that are woven into a mat. Then, this mat is coated with resin, which hardens it, after which it is cut into window frames. The result is an incredibly robust and durable frame material.
Fiberglass frames have become increasingly popular in recent years thanks to their exceptional strength, durability, and resistance to moisture and pests. Plus, fiberglass is an excellent frame material for energy-efficient windows because it has low thermal conductivity.
These frames are dimensionally stable, meaning they do not expand or contract with temperature changes, which helps maintain their structural integrity over time. Like other frame materials (except wood), fiberglass is low-maintenance.
One major drawback of fiberglass frames is that they’re much more expensive than others on the market. One fiberglass window costs between $600 and $1,500. In addition, some fiberglass windows come without weep holes (those tiny holes at the bottom of the frame through which water escapes). They are also not as accessible as other windows, which means you may have to wait longer to have them shipped and installed. Another drawback is that fiberglass isn’t as customizable as other frame materials.

| Pros | Cons |
| Strength and durability
Low-maintenance Resistance to moisture and pests Energy efficiency |
More expensive
Fewer customization options May not have weep holes May not be readily available |
6. Steel Window Frames
Steel window frames are praised for their durability, fire resistance, and strength. These frames can withstand extreme weather conditions and last over 50 years, making them a long-term investment for any home. Steel window frames are hard to break and offer excellent security, thus being ideal for high-traffic areas.
Since steel is incredibly strong (similar to aluminum in this regard), it allows for thin frames, which maximizes window glass areas. Unlike aluminum windows, steel windows are quite heavy, which can make their installation and operation more difficult.
Despite their many benefits, steel frames are more expensive than other frames – one steel window costs $950. Additionally, steel windows transfer heat and cold easily, although their thermal conductivity is lower than that of aluminum.
| Steel window frames | |
| Pros | Cons |
| Strength and durability
Low-maintenance Resistance to rust and corrosion Thin frames |
More expensive
More heavy Not as energy efficient as other materials are |
7. Composite Window Frames
Composite window frames are manufactured using two or more window frame materials. Combined, these materials complement each other’s benefits. For example, Magic’s Hybrid Fusion Frame consists of vinyl, anodized aluminum, and galvanized steel. The aluminum and steel are responsible for our windows’ strength and durability, keeping the vinyl coating intact under extreme weather conditions. In turn, the vinyl coating provides our windows with superior insulation and energy efficiency.
Windows made of composite materials are usually the longest-lasting on the market. They also require minimal upkeep, especially if paired with other advanced technologies like Magic’s Parallex hardware (which makes our casement windows, for example, crank-less and hinge-less).
However, these advantages come at a higher cost. Some composite windows can reach a price of $3,500, depending on what materials are used and the window’s style and size. Some composite materials also have limited color options (but not with Magic – our windows, doors, and window walls can be painted in any color you want!).

Choosing the Right Window Frame Type
Here’s what you should consider when choosing a window frame material:
- Climate and energy efficiency. These two aspects go hand in hand. If you live in a region with a mild climate, there’s probably no need to invest in highly energy-efficient windows – for example, you can install aluminum sliding windows. If you live in a region with cold winters and hot summers – energy efficiency is a priority.
- Maintenance. Windows are installed to perform well for years to come. This means that once they’re in place, homeowners have to maintain them properly to ensure they do not get damaged while under warranty. Therefore, it’s of utmost importance to choose a material with maintenance requirements you’ll have time to take care of. For example, if you have a busy schedule or you travel a lot, wood windows may not be the best choice.
- Budget. In this regard, we should mention that homeowners who want to install energy-efficient windows may benefit from various grants and loans. If you want to contribute to environmental efforts, this is the perfect opportunity!
