How to Select Aluminum Windows?

Release time:2023-07-12

As aluminum popularity increases, window designers keep developing new styles and designs for aluminum windows. The right selection could mean a positive home transformation for appeal and functionality.

So, it's not about picking high-quality windows; it’s about the right material, finishes and matching them with your home. Given the plethora of options for aluminum windows in today’s market, how do you select the right one? Here is what you should consider.



Examine the frame quality.

There are two things to look at regarding aluminum window frames. First, ensure it's rigid and tough with structural integrity so that extreme weather conditions won't affect it. This will guarantee durability. Secondly, you must check if it's resistant to rust, temperature fluctuation, and termites.

That means you only have to select frames that have passed the ASTMB117 salt test. Other factors include the powder coating, anodization, and profile used. For instance, the 5000 and 600 series have better resistance.

Also, note that high-quality aluminum window frames often incorporate thermal breaks. This non-conductive material is placed between the interior and exterior aluminum sections—to enhance energy efficiency.

The accessories like locks, handles, hinges, weatherstripping, and gaskets also contribute to the overall frame quality. The thicker the frame, the better the strength of insulation and soundproofing. Welding joints should also be precise, smooth, sealed with silicone, and strong to guarantee a better connection. Lastly, consider powder-coated frames, as they don't chip or flake even in the harshest conditions.


Check on thermal resistance.

You'd want your home to cut energy expenditure even when using aluminum windows. That's why you have to check on the U value of your aluminum window frame. The manufacturer would normally indicate this.

Climate dictates the U value; a lower U value indicates better thermal performance. But typically, the better U values are always below 0.30. For colder climates, pick the U values that are around 0.20. The 0.3 to 0.4 value may be best for mixed climates.

Also note that the solar heat gain coefficient, air leakage, and visible transmittance may affect the energy efficiency of aluminum window frames. At the same time, you need to adhere to local building codes and regulations.

Also, the type of glass or glazing may dictate thermal resistance where the single-pane glass gives poor insulation properties. Where-else the double-pane or triple-pane windows with insulating gas fillings, i.e., argon or krypton, give better insulation.

Then the low conductivity material for warm edge spacers in double or triple-pane aluminum windows also determines the heat transfer rate. Lastly, there are the thermal breaks, seals, and several glazing layers to consider.


Consider the building regulations and Safety.

Security on aluminum windows involves locks, grilles, and sizes that prevent intruder access. At the same time, you must research local building codes applicable to the location where the windows will be installed. These codes are enforced at the provincial or municipal level, so check with the local authorities or building department for the relevant regulations.

These Standards may dictate your aluminum window dimensions, material quality, installation methods, heat efficiency, and safety requirements. At some point, you may need to talk to professionals or the customer service team of the company you are purchasing from for more guidance.

Your windows must have the CCC mark or CCAA) mark indicating compliance with the required Safety, quality, and environmental protection standards. Also, the CNAS provides accreditation for testing laboratories and certification bodies. If your aluminum window provider has such certifications, you can be guaranteed that you are getting products that adhere to building codes.

Note that the specific regulations and security requirements may vary depending on the region and the intended use of the windows; you may have to talk to a professional for advice.


Consider style

Ensure the aluminum window complements your home. First, assess your window space needs, building location, and environmental factors. Then move to functionality. Do you need fully opening windows or partially opening? Consider their energy efficiency regarding your environment. An aesthetic appeal may have a part to play too. In that case, you have these window designs to consider.

       Casement Aluminum Windows: They are typically hinged on the side and open outward like a door providing excellent ventilation. They also can be easily opened and closed. They are good for limed spaces.

       Sliding aluminum windows feature one or more sashes that slide horizontally to open and close. Their operation is easy and is often used for wider openings.

       Awning Windows: Uniquely hinged at the top, awning aluminum windows open outward from the bottom, creating an awning-like effect. They may remain open during light rain without water entering the room.

       Fixed aluminum Windows: Fixed windows do not open or close. Their sole purpose is to allow natural light into a room or to provide a view. As such, they are non-operable and mostly used with other window styles.

       Tilt and Turn aluminum Windows: Tilt and turn windows offer two opening options. That is tilted inwards from the top for ventilation or opened fully from the side like a casement window. They are good for limited spaces.

       Bay and Bow Windows: Typical bay windows extend outwards from the wall or installation point, creating a bay or bow shape. As such, they create additional interior space, a wider view, and increased entry of natural light.


Go for color

You may imagine color options or use digital tools to simulate how different colors would appear on the aluminum windows in the context of the building. And then pick the one that’s compatible and appealing. 

An analysis of your building style and places where the aluminum window is to be installed will kick you in the right direction. Check whether your design is traditional, modern, or with a specific theme if you contemplate various color options.

Yet even with the plethora of color options, you still have to Consider maintenance and durability. Some neutral colors will remain pristine for ages and withstand weather elements to retain fresh looks.

There is also the need for functionality. You may want aluminum windows that reflect heat away or absorb it; color options may help you achieve the same. Not that Darker colors tend to absorb more heat, while lighter colors reflect it.


Consider pricing

Expensive aluminum windows mean super quality windows. Even with the fear of big spending, there is the assurance of a one-time investment rather than going to the shop for a replacement since you bought cheap, poor quality windows. It's a good value for money, provided the window suits your building needs.

Then largely sized aluminum windows or those that have features like double glazing, thermal insulation, or advanced security systems are highly-priced. The same applies to Higher-grade aluminum frames with enhanced strength and corrosion resistance.

Another factor that could add to the price is the shipment distance, so consider manufacturers that are close by but don't forgo quality. Note that these manufacturers tend to have discounts for larger orders. Smaller orders or customized windows may have a higher unit price.

Lastly, installations may also need special fitting, but the price may be fair if you use installers from where you purchased the windows. And it will cost you more for versatile, decorative, and aesthetic windows.


Check on its craftsmanship.

Craftsmanship starts with the  Manufacturer’s  Reputation: Research the reputation and credibility. You may have to check on their customer reviews, certifications, and any industry awards or recognition they may have received. Then move to  Quality Control Standards. This is where the ISO 9001 certifications come in.

It shows they are compliant with strict quality management standards. Yet sample products may still give you a clue about the craftsmanship quality you will be getting. This is your chance to look for defects, rough edges, and unaligned joints. Finally, check compliance with relevant industry standards and regulations such as ASTM or EN.

At all costs, your aluminum windows should exhibit fine processing, aligned joints, and angle 45 or 90 angles for mainframes and have good sealing. Poor craftsmanship could cause injuries and losses through slipping glasses.


Check its accessories

Typically the thickness of the aluminum window frame and glass and accessories such as hinges, locking gears, handles,  and knobs all play a part in the final window assembly. When selecting them, check on the functionality.

There are casement, awning, sliding, and single-point hinges to consider. You also have multi-point locks, handles, levers, and knobs, like stays and restrictors. Consider the intended use of the window and choose hardware that complements its purpose.

Ensure these accessories are made from durable materials that can withstand frequent usage. Besides, they must be compatible with your window and adhere to compliance standards. While aesthetics may be a concern, you shouldn't forget security. Ensure it has features like multi-point locking systems, key-operated locks, and sturdy handles.


Why should you use aluminum windows in your building?

Aluminum windows have many benefits and are preferred today due to their sustainability. Here are some of the reasons why you may need them.


They are durable

Coupled with surface treatments such as anodization and powder coating, aluminum windows are built to last longer. Plus, aluminum is resistant to corrosion, rust, and harsh weather elements. It's a way around the warping, fading, and flaking.


Aluminum windows are sturdy.

Aluminum windows have a higher strength-to-weight ratio. They won't dent and still will remain strong despite being light. It's also more secure due to the Multi-points shot-bolt locking configuration.


Energy efficiency

Aluminum windows can achieve total sustainability thanks to thermal breaks and reduce energy bills. They minimize the heat transfer rate from within your home to the outside and vice versa. And they are even more efficient when fitted with an energy-saving or lower E glass.


They are easy to maintain

Aluminum windows have almost zero maintenance cost. They won’t rust, corrode or fade. You must only wipe them with a mild detergent to keep them pristine.


They are good for mother nature.

If you wish to adopt environmentally beneficial decisions, use aluminum for your shutters and frames. Aluminum is a material that is both recyclable and non-toxic. Aluminum recycling also doesn't require a lot of energy. Aluminum windows are completely recyclable and require 5% of the resources it took to make them.


Expert tips on buying aluminum windows

You may use several recommendations to choose a high-quality aluminum window. Initially, the aluminum window profile thicknesses ought to be below 1.2mm. Additionally, superior to floating glass includes laminate or tempered glasses. Select the stainless-steel component attachments (such as bolts, pivots, knobs, etc.) when you are concerned about the security and longevity of the windows. Additionally, choosing a POM-made pulley is preferable. These goods are stronger and more resistant to abrasion. They are not readily destroyed and operate smoothly.

The cost of aluminum ingots directly affects the cost of aluminum windows. The cost of aluminum windows is often quite steady. High-quality aluminum windows often cost 30% more than low-quality aluminum windows.

Poor-quality aluminum windows typically have a thickness of approximately 0.6 to 0.8 millimeters and include a significant proportion of subpar and incompatible materials. Therefore, we should consider the pricing of the windows as well as their overall extrusion and spec to ensure that their thickness or sturdiness level matches the necessary national criteria.
