How Thick Is an Aluminum door? All Aspects to Consider

Home / 2025

The thickness of an aluminum door plays a key role in its durability, security, insulation, and overall performance.   

Aluminum door frames are already very important elements in contemporary homes and buildings. However, have you ever wondered if thickness really makes a difference? Sometimes it goes beyond simple aesthetics.  

The answer is a resounding yes. The thickness of an aluminum frame is an important part, as it directly impacts its strength, insulation capacity and overall performance, although lately it also goes hand in hand with aesthetics.  

Thicker aluminum doors are stronger and more resistant to dents, bends, and damage. This is especially crucial for exterior doors exposed to weather conditions or high traffic areas. 

In this article we are going to tell you all about the thickness of an aluminum door and all the aspects to consider for your project.  

What is The Thickness of An Aluminum Door Frame? It All Depends on the Product 

Aluminum door frames come in different thicknesses, adapted to different types of doors and their specific uses. This thickness does not only impact the design, as it’s important for construction and architecture.  

The Thickness Depends Mostly on the Type of Aluminum Door Chosen for Each Project. Here Are Some Examples:  

  • Folding doors: These doors usually require thinner frames, between 30 mm. and 40 mm., ideal for residential or light commercial uses where a heavy structure is not needed.  
  • Entrance doors: For increased security and better insulation, 40 mm. to 50 mm. frames are best suited in this case.  
  • Sliding doors: Due to frequent use and the need for smooth movement, 40 mm. to 50 mm. frames are usually the best choice.  

Complying with local regulations and industry standards not only ensures better performance, but also guarantees energy efficiency and long-term durability. Choosing the right thickness is key to the functionality and longevity of your doors, which is why professionals should advise you on the construction, design and installation of aluminum doors.  

The optimal thickness can depend on the intended use, climate, and security needs. For example, residential doors may have different thickness requirements compared to industrial or commercial ones. 

What Factors Influence the Thickness of An Aluminum Door? 

The thickness of an aluminum door frame is an important choice; it depends on several elements ranging from the type of door to environmental conditions and the specific needs of the user. Here we break down the key factors:  

  1. Door Type

As we mentioned above, the type of door is the most important factor in determining the thickness of the frame chosen. Some products have factory construction, but this is up to the professional(s) in charge of the project to decide.  

  • Folding doors: Due to their lightweight and compact design, they tend to work well with thinner frames, making them easier to fold and move.  
  • Entry doors: To ensure greater security and soundproofing, it’s advisable to use sturdier and thicker frames.  
  • Garage doors: They require thicker frames to support their weight and guarantee stability, especially in large structures.  
  • Sliding doors: The sliding mechanism requires a medium-thickness frame that balances durability with frequent use.  
  • Swing doors: Like entry doors, these doors need strong frames that will withstand daily use and offer additional stability.  
  1. Environmental Exposure

Climate is a determining factor. If the frame is exposed to extreme conditions such as heavy rain, high winds or extreme temperatures, opting for a thicker frame is essential to ensure longevity and structural support. 

  1. Safety and Soundproofing Requirements

In several projects, one of the important quality requirements is the security the aluminum door can provide against various problems and soundproofing.  

  • Security: Doors such as entrance or garage doors, which are often key access points, benefit from thicker frames capable of resisting intrusion attempts.  
  • Soundproofing: A thicker frame also helps block noise, making it an excellent choice for homes or offices located in areas with high traffic or ambient noise. 
Aluminum doors have a standard in terms of their tickness.

What Factors Should We Consider When Choosing the Thickness of An Aluminum Door? 

When choosing the thickness of an aluminum door frame, it is critical to consider several factors to ensure functionality, aesthetics and cost. Application and location are key, as interior frames tend to be thinner because they are not exposed to the weather, while exterior frames require greater thicknesses to withstand the elements and provide durability. 

For specialized doors, such as patio doors or storefronts, sturdier frames are a must because of the need to support large panes of glass or meet stringent security standards. 

Aesthetic design also plays a role, as thin frames are ideal for modern and minimalist styles, while thicker frames add sturdiness and an industrial touch, as well as being perfect for large or heavy doors. 

Energy efficiency is another important aspect, especially in regions with extreme climates. Thicker frames with thermal brakes reduce heat transfer, better regulate temperature and lower energy costs. 

In addition, thickness affects sound insulation. In noisy areas, such as busy streets or urban areas, a thicker frame combined with a solid door can offer greater sound insulation, providing a quieter environment. 

However, budget is undoubtedly one of the most important aspects, as thicker frames tend to be more expensive due to the materials and manufacturing processes involved. It is essential to find a balance between cost, durability and specific needs. 

The important thing is to approach professionals and evaluate all the necessary conditions to choose the best option. 

Comparing Thin and Thick Aluminum Door Frames 

When it comes to choosing an aluminum door frame, deciding between thin and thick profiles can make a big difference depending on your specific needs. Both styles have unique advantages that make them ideal for different contexts. 

Thin frames feature a modern, minimalist design, ideal for those seeking a sleek, contemporary aesthetic. These frames allow for a larger glass area, maximizing natural light and providing a clean look, especially appreciated in modern homes and sophisticated commercial spaces.   

They’re also an economical choice, as they tend to be less expensive and work well in low-impact areas, such as interior doors or spaces with less traffic. Their lightness and simplicity make them an affordable solution for those who prioritize style over sturdiness. 

On the other hand, thick frames offer superior strength, making them ideal for doors that need to withstand heavy use or adverse conditions. These profiles are designed to resist impacts, deformations and external forces, making them the perfect choice for exterior doors exposed to extreme climates or high traffic. 

In addition, their robustness allows the incorporation of advanced locking systems, offering greater security against theft and better protection against the elements. If security, durability and strength are priorities, thick frames are the right choice. 

Ultimately, the choice between thin and thick frames depends on the specific needs of your space. While thin frames offer style and affordability, thick frames ensure safety and strength. Analyzing your environment, intended use and functional priorities will help you make the best decision. 

It is necessary to choose the tickness of the aluminum door, depending on the needs of your project.

Why choose an aluminum door 1

7 Reasons For Choosing An Aluminum Door For Your Project 

Home / 2025

The front door is the first line of defense for any home or business. Beyond its aesthetic function, it must offer security, durability and efficiency. In this sense, aluminum entrance doors have become one of the most reliable options, combining strength with a modern and functional design.   

If you’re considering replacing your front door or looking for the best option for a new construction, here we explain why aluminum is the smartest alternative and how it can improve the security and comfort of your property.  

In fact, in all our time working with these devices, we have come to know 7 reasons to choose an aluminum door for your project, regardless of its nature.  

Why Use An Aluminum Door For Your Project?   

The combination of aluminum and glass has been very popular lately. In addition to security and soundproofing, it’s an elegant and stylish system. Still not sure whether to install this in your home or business? Here are 7 great reasons to do so.  

Reason 1: Greater Security and Resistance 

Aluminium is an exceptionally strong and light material, making it an ideal choice for security doors. Compared to wood or steel, it offers a much higher strength-to-weight ratio, meaning it can withstand impacts and shocks without bending or breaking easily. 

Furthermore, many aluminum doors are designed without visible welds or with strategic reinforcements at their joints, reducing weak points that could compromise the integrity of the structure.  

If you want a door with additional protection, you can opt for models that integrate laminated safety glass, multipoint locks and internal reinforcements, increasing resistance against intrusion attempts.  

Reason 2: Aluminum Provides the Best Weather Resistance On Its Own 

One of the main advantages of aluminum is its high resistance to adverse weather conditions. Unlike wood, which warps with humidity, or steel, which can rust, aluminum does not corrode, does not oxidize and is not affected by extreme temperatures.   

This makes it an ideal choice for any climate, from areas with high humidity to regions with strong winds and sudden changes in temperature. It doesn’t matter if you live on the coast or in a rainy area, an aluminum door will remain in perfect condition without the need for special treatments.  

Furthermore, if you live in a desert or a place where it snows, it can still be easily adapted, making it a universal system. 

Reasons-For-Choosing-An-Aluminum-Door

Reason 3: Low Maintenance and Long Lifespan 

If you’re looking for a door that keeps its impeccable appearance without effort, aluminum is the best option. Unlike other materials that require varnishing, painting or protective treatments, aluminum doors only need occasional cleaning with products that the manufacturer recommends.   

In addition, most models have finishes that are resistant to scratches and discoloration, ensuring that the door looks like new for many years. You won’t have to worry about constant repairs or additional maintenance costs.   

Reason 4: There’s No Better Door In Terms Of Value For the Money 

Although the initial cost of aluminium may be similar to a high-end steel or wooden door, in the long term, it’s a much more profitable investment. There are three main reasons for this:   

  • Less maintenance: It doesn’t require varnishes or periodic treatments. 
  • Greater durability: Its lifespan is significantly longer than that of other materials.  
  • Energy savings: When combined with high thermal efficiency glass, it helps maintain stable interior temperatures, reducing the consumption of heating and air conditioning.  

If you’re looking for a door that combines security, aesthetics and low maintenance costs, aluminium offers an excellent cost-benefit ratio for any project.  

Reason 5: Best Fire Protection 

Home security is not only about preventing burglaries, but also about minimizing risks in the event of disasters such as fires. Aluminum is a non-flammable material, which means that it does not burn or contribute to the spread of fire.   

In the event of a fire, an aluminum door acts as a protective barrier, offering greater resistance to heat and preventing flames from spreading rapidly inside the house (or the exterior). This makes it a much safer option compared to wooden doors or even some steel doors, which can warp under extreme temperatures.   

Combined with an emergency exit, you’ll have a high-quality and very safe system.  

Reasons-For-Choosing-An-Aluminum-Door-1

Reason 6: Aluminum Is the Most Versatile and Environmentally Friendly Material 

Beyond its functionality, an aluminum door also adds a touch of modernity and elegance to any property. Available in a wide variety of colors, finishes and styles, it adapts perfectly to both contemporary homes and commercial buildings.  

Furthermore, as it’s a highly recyclable material, aluminum is a sustainable and environmentally friendly option. When you want to change it, the systems can be recycled or given a different use.  

Reason 7: Compatibility With Advanced Security Systems  

Aluminium entrance doors are fully compatible with intelligent security systems, such as electronic locks, surveillance cameras and access sensors.   

If you’re looking for an extra level of security, you can combine your door with digital access controls, security codes or biometric recognition technology. This makes aluminium not only a secure option, but also one that is adaptable to technological advances.

Curtainwall System by PRL

Curtainwall: What It Is and Why It’s a Trend in Architecture In 2025

Home / 2025

With the advent of reinforced concrete and steel structures, thinner columns that could support a building became unfashionable. Even more surprising was the discovery that they could be erected without relying on the façade, which freed the exterior walls from structural load and an admittedly dull style. 

Today, these so-called “curtainwalls” not only provide a modern and beautiful architectural look, but also contribute to the sustainability and protection of the building envelope. 

But what exactly is a curtain wall in construction and what is its role in the long-term preservation of the building? Below, we will delve into everything you need to know about these systems, describing the different types that exist, the materials used and their main benefits to implement them in 2025. 

What Is a Curtainwall? A Cross Between Style and Functionality 

A curtainwall consists of a lightweight, framed exterior structure that integrates infill panels and partitions without structural function. This type of glazing has become one of the most widely used in modern architecture. Just look at most of the large skyscrapers or buildings that were created less than 10 years ago. 

Think of those tall city buildings with floor-to-ceiling glazed facades. Those transparent, framed surfaces are, precisely, a curtainwall. 

Do they alone support the entire building? No, they do not. The curtainwall frame is attached to the main structure of the building, so it’s not load-bearing, but it has other uses. 

Does it only serve an aesthetic function? Not necessarily. Typically, commercial curtainwalls protect the integrity of the envelope against factors such as moisture, temperature extremes and ultraviolet radiation. 

Although thin, they resist inclement weather thanks to corrosion-resistant materials and the fact that any forces they exert – for example, wind pressure – are transferred to the building’s frame. 

The construction of these systems requires various inputs, such as sealing elements, glazing, structural adhesives and waterproofing products, to ensure their proper performance and durability. 

Many people confuse curtainwalls with somewhat similar structures such as storefronts or window walls. However, there are important differences in their implementation and their most common uses. 

  • Curtainwalls vs. window walls: Window walls incorporate the glass within the structural elements and each section only spans one floor. 
  • Curtainwalls vs. storefronts: The units of a curtainwall system are usually taller than those of a typical storefront, which generally measure between 3 and 4 meters and only cover the first floor or one room. 
Curtainwalls are a big trend in architecture.

How Are Curtainwalls Constructed?

Curtainwalls are basically constructed of two materials, one for the frame and the other for the infill. Both must complement each other for proper operation. 

How Are Curtainwall Frames Constructed? 

For some years, aluminum has become the material par excellence for the construction of curtainwall frames, because it’s a material that naturally withstands corrosion for many years. 

  • Builders began to use it because it has a great strength-to-weight ratio, plus it’s readily available 
  • But it’s also ideal for many (or most) architectural styles, since the aesthetic concepts we can implement with aluminum are practically unlimited.  

Other materials that can be used for certain types of projects are steel and wood. 

What Is Used For Curtainwall Filling? 

Usually the panels used to fill curtainwalls are made of glass. Glass is highly customizable, with multiple colors and opacities, plus viewability, thermal insulation and, of course, weatherability in most climates.  

In addition, glass is an excellent value for money material. For this reason, it is always chosen for 95% of the projects.  

But for more demanding projects, aluminum can be used, which keeps the price low with high durability and, in other applications, stone can also be used. 

Curtainwalls are a big trend in architecture and projects

What Are the Advantages of Curtainwalls Over Other Solutions? 

Throughout the text we have seen some of the advantages of installing a curtainwall in our projects. But we want to list them below: 

Functional versatility: Curtainwalls allow the integration of operable windows, shading devices and ventilation systems, which optimizes the use of the building and brings comfort to its occupants. 

Increased market value: Incorporating a curtainwall improves the aesthetic appeal of the building, which in turn can increase its market value. 

Energy optimization: By reducing the need for artificial lighting and controlling solar heat, high-quality curtainwall systems contribute significantly to a building’s energy efficiency. 

Improved architectural appearance: The installation of curtainwalls provides a modern and elegant look to the façade, raising the level of design and distinction of the building. 

Protection from the environment: These systems act as an effective barrier against extreme weather conditions and the wear and tear generated by the passage of time. 

Customized adaptation: The size, shape and style of curtainwalls can be adjusted to meet the specific requirements of any building project. 

FAQs 

Find out a little more about the Curtainwall system

What Is a Curtainwall? 

A curtainwall is a thin, lightweight system, usually made of aluminum and glass. Unlike other building materials, these walls do not have a structural function. Their design allows them to support only their own weight, while transferring wind and gravity loads to the main building structure. In addition, they are designed to be air and water resistant, ensuring that the interior of the building remains dry and protected. 

What Are the Best Types of Curtainwall Systems Available Today?  

There are three main curtainwall systems: 

  1. Face-sealed: They rely on a tight seal between the wall units and their frame to prevent leaks. 
  1. Water-managed: Incorporate drainage systems to divert moisture and prevent water from entering the building interior. However, this system does not create a complete air barrier. 
  1. Pressure-balanced: This system provides maximum air and water resistance. Its design keeps the interior of the building completely sealed, while the exterior frame drains water efficiently, offering the most robust and reliable solution. 

What Are the Key Features of Curtainwall Systems That We Can List? 

Curtainwalls are designed to meet structural and climatic challenges, considering factors such as: 

  • Thermal expansion and contraction. 
  • Building movement and oscillation. 
  • Thermal efficiency. 

In addition, they can be customized with different types of glazing, including interior, exterior or structural options. They can also incorporate a rod frame divided by mullions, creating smaller panes of glass that offer lateral resistance and allow for thermal movement. 

For added aesthetics, curtainwalls offer a variety of front cover options that allow for unique and visually striking designs, without compromising project efficiency or budget. 

What Are the Main Advantages of Curtainwalls? 

  • Cost savings: Due to their lightweight materials, curtainwalls are an economical choice for exterior cladding, especially on larger projects. 
  • Energy efficiency: Curtainwalls help reduce air and water infiltration, which optimizes building energy consumption. This can translate into lower heating, cooling and lighting costs. 
  • Design flexibility: These systems can be installed in different sizes, from small units to large areas spanning multiple floors, or from floors to ceilings, adapting to specific project needs. 
  • Modern aesthetics: Curtainwalls offer a contemporary and versatile design that significantly enhances the exterior appearance of any building

What is a Curtainwall and Where is It Used? 

Curtainwalls are designed for low and medium-rise buildings, and are not load-bearing structures, but lightweight façades that are attached to the main structure of the building. They are composed of aluminum and glass frames and are designed to resist wind forces and water infiltration, as well as provide thermal and acoustic insulation. 

There are several types of curtainwalls. For example, at PRL we offer 3 complete systems and produce in-house, cut-to-size frames, formed aluminum infills and steel reinforcements. Each curtain wall package includes your choice of glass type and all mounting components, ready to install: 

  • Pressure glazed systems  
  • Structural silicone glazed systems 

Regardless of the system, curtainwalls will accept various types of glass, depending on the project requirements 

  • Tempered glass 
  • Low-E glass   
  • Insulating glass (IG) units  

Continuing along these lines, curtainwalls have some important advantages for businesses:  

  • Functional flexibility: Curtainwalls allow the integration of elements such as operable windows, shading devices and ventilation systems, enhancing the functionality of the building. 
  • Added value: Incorporating a curtainwall increases the attractiveness and value of the building in the real estate market. 
  • Energy efficiency: High-quality systems improve energy efficiency by reducing the need for artificial lighting and controlling solar heat. 
  • Aesthetic appeal: They offer a modern and elegant appearance, enhancing the architectural image. 
  • Protection: They act as a barrier against adverse weather conditions and wear and tear. 
  • Customization: They can be customized in size, shape and design to meet specific requirements. 

So, Which Option Is Ideal For Me? 

Storefronts and curtainwalls are two very similar options in terms of construction, featuring the highest quality aluminum and glass.  

But, the main difference, as we saw, is the design features and their main uses 

The storefront is an ideal solution for commercial and/or residential use, both exterior and interior. It’s a wall and entrance door that allows full visibility, but it is not as large as a curtainwall.

The choice between aluminum façades and curtain walls depends on the specific needs of the building, including design, functionality and budget. Both are commonly used for the exterior façades of commercial buildings, but they have different purposes and characteristics. 

Storefront 

These are mainly used for commercial and retail entrances, such as shop windows, lobbies and shop fronts. They are often used for ground-level applications, such as shop fronts or the first floors of a building. 

PRL manufactures a combination of frames and glass panels, with narrow horizontal and vertical aluminum frames. They are lightweight but durable, designed to support moderate structural loads and don’t need a deep structure behind them. 

✅ PRL’s newly designed modern aluminum storefronts come with thermal breaks in the frame to improve energy efficiency.  

Aluminum storefronts are generally non-load-bearing, easy to install and flexible, and require little maintenance. 

Curtainwalls 

Curtainwalls are mainly used in skyscrapers and large commercial buildings as an outer shell or façade. They cover entire building façades or several floors and act as a climate barrier. They’re designed to withstand wind, rain and other external elements. 

For PRL’s load-bearing curtainwalls, we use 3 different curtainwall systems. These are non-structural cladding systems attached to the building structure, with a more substantial frame and larger glass panels.  

These curtainwalls are designed to span several floors and are load-bearing in the sense that they are attached to the building structure, but the walls themselves do not support significant vertical loads. All PRL curtainwalls are constructed with advanced insulating glass units (IGU’s), which provide better thermal performance compared to storefront systems and offer better weatherproofing.
