Aluminum Window Extrusion Profiles FAQ

Here are most of the questions related to aluminum window extrusion profiles. We hope you will find the answer to your question. If not, please leave us a message.

What is the durability level of aluminum window frame extrusion profiles?2024-01-26T07:07:40+00:00

Our aluminum extrusions for windows are durable since the materials are highly resistant to corrosion and other mechanical/environmental factors. During the extrusion process, the aluminum alloys undergo an aging process, which enhances durability. Specifically, aging of the alloys ensures that the surface particles precipitate evenly. The result is a hard surface that can ward off different elements. Typically, our aluminum profiles can last for well over decades.

How important is the thickness of the window aluminum extrusions?2024-01-26T07:01:06+00:00

The thickness of the window aluminum extrusions affects the heat shielding performance of the window. Here are the elements that are affected by this attribute:

  • Weight– there must be a balance between the weight of the window and heat insulation
  • Thermal conductivity resistance– a thicker aluminum extrusion provides higher thermal conductivity, and vice versa
  • Thermal insulation– For higher thermal insulation, thicker profiles of aluminum window extrusions are preferable. To protect the quality of items and human comfort indoors, this property is paramount in windows.
How does the aluminum window extrusion option compare to wooden window frames?2024-01-26T06:56:18+00:00

Many people with remodeling projects ask this question all the time. The aesthetic value of wooden windows is indeed unmatched. However, wood can be more delicate than aluminum window frame extrusions. This point is critical because the durability of a window is a big factor. That’s where window aluminum extrusions come in. Aluminum alloys are durable, formable, and look good. Wood finish aluminum can meet your demand of wood grain appearance on aluminum window frames.

Is the machinability of the aluminum window extrusions a big factor?2024-01-26T06:51:01+00:00

Yes, machinability is a valuable element of any architectural or construction project. It makes the processes efficient. With our materials for window framing – 6063, 6060, and 6061 – cutting and shaping using the common processes is not an issue.

What are the connection options for the aluminum window frame extrusions?2024-01-26T06:40:56+00:00

Depending on your window framing design, you can use any of the several connection methods for the aluminum window frame extrusion profiles. The snap-fit connection is very easy and fast. It also adds the aesthetic element by concealing screw heads. It is simple because it only involves the top extrusion sliding and fitting into the bottom one. A positive snap works perfectly for aluminum alloys because they naturally flex.

Another option would be the more common screw port method. You can choose this method for easy disassembly of the connection. It consists of either threads or screws.

The profiles can also be connected using an interlock whereby a pair of profiles slide over each other to create a strong connection. It takes advantage of the male and female features on the profiles. As long as the space is not congested, this connection is effective.

Other connections that you can consider for your aluminum window extrusions are hinges, nut tracks, and corner cleats.

What is the quality control process for your aluminum window extrusions?2024-01-26T06:38:05+00:00

Fonnov Aluminum places immense consideration on the quality of aluminum window extrusions produced. For guaranteed quality, we have a dedicated team focused on quality inspection and assurance. We have certifications for quality both nationally and internationally. Our efforts to quality products are present from the raw material stage to the dispatch stage. For instance, we have sampling tests in the manufacturing stage. We are always keen to deliver the correct cross-section size, so we do these tests regularly.

The maintenance requirements of these aluminum window extrusions2024-01-26T06:36:37+00:00

These window extrusions have very minimal maintenance requirements. A simple clean of the extrusions is enough.

Is there a cost estimate for your aluminum window extrusions?2024-01-26T06:34:20+00:00

There is no general cost for our aluminum window extrusions, but there are several elements we can use to estimate the cost. The exact amount would depend on the following factors:

  • Quantity– In most transactions, high-volume orders attract higher discounts as compared to smaller volumes. Therefore, ordering more aluminum window profiles can be more cost-effective.
  • Surface finishing – there are different types of surface finishes, each with its own set of requirements. Costs can differ depending on the complexity of the surface finish.

In short, there is no one-size-fits-all when it comes to the cost of aluminum window extrusions.

For windows subjected to high stress, what design feature do you use?2024-01-26T06:31:27+00:00

Whether in 6063, 6060, or 6061 alloy, our aluminum window extrusions meet the stringent standards needed for high-stress applications. They are strong, tough, and have good machinability. The copper and magnesium content of these alloys gives them high strength, which makes the product reliable under high stresses. You will be amazed at how fracture-resistant these window frame extrusions are.

Can the corrosive nature of the area affect the aluminum windows for a project at the coast?2024-01-26T06:25:02+00:00

No need to worry when using our super durable coated aluminum window extrusions in your coastal projects. Super durable coated aluminum extrusions are generally corrosion resistant and, thus are ideal for the humid and saline conditions of the coast. Even where rain is frequent, these window frames will perform excellently. Note that we can further enhance the corrosion resistance through super durable coating or anodizing for more reliability and longevity.

Why is aluminum alloy most applicable for window regarded for sustainability?2024-01-26T05:30:49+00:00

Window frame manufacturers who use aluminum alloys, know the important place of this material in today’s sustainability goals. The aluminum alloy is not only corrosion-resistant but also recyclable. The two properties are ideal for the manufacture of aluminum window frame extrusion profiles for a wide range of applications. For your environmental care goals, consider these aluminum extrusions.

What grades of aluminum extrusion do you use for window frame?2024-01-26T05:27:28+00:00

We use several aluminum alloy grades for aluminum window frame extrusion profiles. These grades are in the 6000 series –6063, 6060, and 6061.

The 6061 grade is the stronger, thus applicable for windows that have high strength requirements. Other factors that make it suitable for window profiles are low weight, corrosion resistance, and workability.

More popular than this grade is the 6063 aluminum grade. This one has excellent corrosion resistance and formability. Its capability for machining, welding, and cold-working is also high. That’s why it is the most popular option for aluminum window extrusions.

What makes FONNOV aluminum window extrusions suitable for building projects?2024-01-26T05:22:36+00:00

First, they are aesthetically appealing due to the excellent surface finish that we provide. Then, these extrusions have been built for strength that suits the demands of a window. This blend of functionality and aesthetics is highly rated by the users.
