Exterior Wall Cladding Panels: What You Need To Know

You&#;ve seen it on many new commercial buildings: usually as large rectangular panels with hidden joints, giving the building a tiled, flush appearance. But it comes in more forms than you might expect. It&#;s a relatively new exterior feature, and it serves many important functions. We&#;ll cover what it can be made out of, what it is meant to do, and even a bit of the history behind it. We&#;re going to go in-depth on exterior wall cladding panels.

Those panels have more than one job. They insulate the building, helping to regulate internal temperature and contribute to energy efficiency, and they create a unique and thoroughly modern look in most applications. But more importantly, these panels protect buildings from the many environmental stresses they face, like rain, UV radiation, and wind. These kinds of panels are the external part of an exterior wall system called rainscreen cladding. 

Although this post should be informative, it may not address absolutely everything you&#;ve ever wanted to know about wall cladding systems. We&#;re always available to talk more about anything you&#;re in the market for and to help you find the right fit. Get in touch if there&#;s anything you want to know more about your rainscreen options.

Rainscreen Materials

Rainscreen cladding is an exterior feature of buildings that prevents water and moisture from penetrating the building envelope. It is a system with three parts: the external cladding, the ventilated air gap behind that, and the water-resistant barrier attached directly to the frame of the building. 

Cladding repels water with panels or other weatherproof external layers, while also draining and evaporating water that enters the air gap. Although it is primarily functional and insulative, cladding also contributes to bold and aesthetically pleasing facades. 

Although it is a relatively new sight in the United States, rainscreen cladding has been used in Canada and Europe for decades. Having originated in Scandinavia in the 60&#;s, it is a relatively new and modern architectural option. There are a range of materials available that are suitable for rainscreen cladding. Here are just a few examples.

Fiberboard

An extremely durable and long-lasting material, fiberboard makes for cladding that is heavy and somewhat expensive but will stand up to bugs, fire, rot and nearly everything else.

Cement Board

Cement board offers the performance, aesthetic flexibility, and cost-effectiveness to be a go-to cladding material for architects and builders.

Extruded Concrete

The extrusion process creates concrete panels that are very thin but strong, an ideal material for rainscreen cladding. For a great read on why these panels are so well-fitted to rainscreen cladding, check out this article from Architectural Record.

The Many Materials Exterior Panels Are Made Of

One of the advantages of rainscreen cladding is that it can be made from a wide range of materials. Metal, stone, wood, and synthetic polymers are all likely candidates for paneling, offering different aesthetic and functional qualities. 

Aside from aesthetics and exterior design, architects and designers may choose one material over another for any number of reasons from costs to environmental concerns to ease of maintenance or installation. There are also finishes available for synthetic panels that resemble natural materials like bamboo or sandstone, meaning that rainscreen cladding can achieve the functionality and cost of synthetics with the aesthetic appeal of natural materials. 

The possibilities that come with exterior panels can make the choice a complicated one for some building projects, especially when there are multiple high-priority considerations to be made when selecting materials. Each material has qualities that make it unique, and more or less appropriate depending on specific project requirements. You can learn more about some of these unique qualities from this post as well.

From natural materials like stone to composite materials and synthetics, we&#;ll break down some of the most common materials used in commercial wall panels.

High Density Polyurethane

Synthetic materials offer the possibility of designing panels that resemble other materials without the associated drawbacks, giving architects more design flexibility against other project requirements. Some of the possibilities are synthetic brick, bamboo, stone, or tile.

Fiber Cement

Even with the wealth of available cladding options, fiber cement panels often stand out for their capacity to fulfill all the many needs of builders when it comes to architectural cladding that is affordable, attractive, easy-to-install, and effective. Learn more about this amazing material with an article from Architectural Record.

Ceramic

Tile and other ceramic panels can create some of the most visually striking facades around, with a range of colors and patterns available. Ceramic is a very low maintenance, environmentally friendly option.

Stone

One of the strongest and most versatile natural materials available is stone. From sandstone to slate, these panels are durable and unique, though they can come at a high price. 

Metal

Few materials have more modern visual appeal than metal, which can come in a wide range of finishes. Steel is the most common material used for metal panels, although copper, aluminum, titanium, and zinc are also used. Find out more about the different types of exterior metal wall panels in this post.

Concrete

The simple, stark look of concrete without the heavy machinery, scaffolding, and labor-intensive installation.

Wood

Another natural material with unparalleled visual appeal is wood, which when treated properly, can stand up to the elements surprisingly well.

Glass

Glass paneling and glass curtain walls bring the benefits of daylighting to the exterior walls of a building. The reflective properties of glass can also create striking facades.

Balancing Compliance, Cost, and Performance Without Compromise

The most important thing to get right every time is compliance. No matter what, It&#;s never cost-effective to do it over. 

The first step is keeping up to date on changes in codes and building ordinances. From reading the latest publications to attending legislature meetings, there are plenty of opportunities to stay up to date. 

When shopping for materials, it&#;s important to look for the greatest value rather than the lowest price. It&#;s never cost-effective to do it over. Look for materials that offer value in the form of high performance, durability, or other factors. Making a value-oriented decision can help you build something that lasts and doesn&#;t have you returning to a job site when you weren&#;t planning to. 

When you shop for materials, be sure to choose the right vendors. Good vendors will help you fully consider your options and they&#;ll prioritize getting you the right product for your job. The best vendors will help you increase the value of your project with deals, offers, and more. Building relationships with vendors is one of the best things you can do to help yourself consistently find the best value and the right materials for your commercial building projects.

What Are Metal Wall Panels? Pros, Cons, & Types of ...

Editor&#;s Note: This article has been updated to include new information since its original publication.

If you&#;re new to metal construction or researching various types of exterior wall cladding, you will find that there are different kinds of metal wall panels available, but what are metal wall panels? If you choose to use a metal wall panel system, what are the advantages and disadvantages of using this material?

At New Tech Machinery, although we specialize in manufacturing portable rollforming machinery to make metal roof and wall panels, we understand the importance of being an educated customer. Knowing the basics of metal wall panels, the various types you can use on commercial building applications, and pros and cons of using metal materials for wall cladding can help you decide if this is the best choice for your metal construction project. 

Throughout this article we&#;ll cover:

  • Advantages of using metal wall panels
  • Problems that can occur using metal for exterior wall cladding
  • Different types of metal wall panels

Advantages of Using Metal Wall Panels

Whether you&#;re considering rollforming your own metal panels or using a panel supplier, knowing how metal stacks up to other common exterior wall materials like vinyl, brick, stone, or wood is key. Here are some of the benefits of using metal wall panels:

They are visually appealing &#; Metal wall panels are beautiful in both exterior and interior building applications. They are available in various colors and can be formed into different shapes or profiles to suit your design preference.

They are less expensive to install and maintain &#; Because they are lighter weight, metal panels can be installed quicker, and require less maintenance than other exterior wall systems like brick, vinyl, or stone. Depending on the type of metal wall panel system you choose, this type of wall cladding is easier to install.

They hold up well against fire, rain, and everyday wear and tear &#; Metal materials are great protective barriers against fire and extreme weather conditions. When used with a weather-resistant barrier, they can also prevent rain from getting inside a building.

They are sustainable and widely used in architecture &#; Metal wall panel systems are eco-friendly, often recyclable or made of recycled materials, and are used in all sorts of building applications including commercial, industrial, and institutional.

Disadvantages of Using Metal Wall Panels

While there are many advantages of using metal in a building&#;s architecture, there are some potential issues you may encounter when using metal as the main component in a structure&#;s wall panel.

They are susceptible to oil canning &#; Oil canning describes a &#;waviness&#; that appears in flat areas of a metal panel or metal coil, often caused by stresses on the material itself or during the rollforming or fabrication processes. It&#;s typically an inherent characteristic of light-gauge, cold-rolled flat metal products and can happen when using any metal material.

May encounter corrosion from interactions of different material types &#; When different metal types are combined, a negative interaction may occur and cause problems such as water runoff stains and galvanic corrosion. 

Galvanic corrosion happens when a certain type of metal comes into contact with another type, causing the least noble material to corrode. Water runoff from one type of metal onto a different type of metal can cause staining or corrosion.

Can experience denting &#; Although metal wall panels and metal exterior cladding is less damaged by dents or dings, that doesn&#;t mean that it won&#;t happen. Especially areas of the wall that are lower to the ground, these metal panels can be exposed to weather, debris, even foreign objects hitting the wall.

Types of Metal Wall Panel Systems

Although there are numerous kinds of metal materials with which you can make metal wall panels, there are three common types of metal wall panel systems used in metal construction. Each one has unique properties, depending on the kind of structure you&#;re building, environment, installation, and properties.

Single Skin

Single skin metal panels are made of a single layer of metal that&#;s rollformed or preformed into a specific shape or profiles like a flush wall, WAV, or batten, and are typically made as concealed fastener or exposed fastener panels. Most wall panels of this type can be installed horizontally or vertically and in less time and cost than other metal wall panel systems. 

Insulated or uninsulated, single skin metal panels can be made with protective coatings that help fight corrosion and fading. However, they are still susceptible to damage due to their being less rigid, unlike the MCM and IMP panels which have a core between the metal panels. Because of their higher flexibility, they also have a greater chance of oil canning. 

Features of single skin metal wall panels include: 

  • They are lightweight and easier and lower cost to install.
  • They are 100% recyclable.
  • Single skin wall panels can be installed in almost any environment.
  • They are available in various shapes and profiles.
  • They are the most popular metal wall panel in commercial building applications.
  • They are capable of handling thermal expansion and contraction better than IMPs or MCMs.

Metal Composite Material (MCM)

Metal composite material panels are formed by joining two sheets of painted or natural metal sheets (typically aluminum but can also utilize other materials like steel, zinc, copper, stainless steel, or titanium) and bonding them to a polyethylene center.

Why use an MCM panel?

  • You won&#;t have a problem with oil canning in the panels because of the fire-retardent core in between the metal panels.
  • MCM panels are typically lighter in weight and can stand up well to harsh weather.
  • MCM panels retain their flat shape even when installing them.
  • When properly designed, tested, and installed, MCM panels are capable of protecting building exteriors against harsh elements, air, and water infiltration.

Insulated Metal Panel (IMP)

As the name suggests, this lightweight metal wall system is made with two coated metal panels, typically aluminum or steel, formed on either side of an insulating foam center. Because of their insulation capabilities, lightweight design, and quicker installation, insulated metal panels are used in all sorts of building applications. 

They make an excellent choice for commercial and institutional buildings, climate-controlled buildings or those used for cold storage, and architectural projects. IMPs can also be installed vertically or horizontally, in various colors, shapes, and panel widths. Because they have the insulation already integrated into the panel, IMPs can be installed in one step and create an effective barrier to air, water, and vapor.

Insulated metal wall panels may be the right choice for certain building applications because:

  • They require less maintenance than some other exterior wall cladding or siding.
  • They are less expensive to install because of the lightweight nature of the panels, need fewer fasteners, and provide greater wall coverage.
  • IMPs are typically factory assembled, not rollformed on-site, and relatively inexpensive to ship to job sites.

Final Thoughts

While metal wall panels are growing in popularity in all types of buildings, there is a lot that goes into their design and application. If you&#;re deciding to use metal for your exterior wall cladding, or want to know which metal wall panel system is right for you, just remember these key points.
