While it’s essential to focus on the building’s interior, the exterior should also speak for itself. Your clients expect structures that look modern, perform well, and last for a long time without extensive upkeep. There are multiple exterior finishing options that you can explore, but the material that truly stands out is Galvalume. Want to know more? Let’s break down Galvalume cladding and why it’s a popular, future-proof solution.
What is Galvalume Cladding?
Galvalume cladding is the application of a unique aluminum-zinc alloy to a building’s exterior to protect it from corrosion. Besides that, it also enhances the overall appearance and thermal insulation, offering you long-term savings. Due to these factors, the galvalume market is rapidly growing and is expected to reach USD 13.7 billion by 2031.
Types of Coatings for Cladding Galvalume
You can opt for bare galvalume; however, if you want enhanced protection and better aesthetics, you can explore the following coating options when galvalume cladding:
- Acrylic: If you are looking for a clear, organic coating, acrylic is the ideal option. It provides a smooth, glossy finish and is free from oil. Not only this, but it also offers the genuine metallic silver-gray color of Galvalume, while providing increased protection from UV, smudges, and corrosion.
- Polyvinylidene Fluoride (PVDF): PVDF is actually a non-reactive thermoplastic fluoropolymer used in solvent-based paint systems. It’s known for its superior weathering, flame resistance, and color stability. Opting for it means that you don’t have to worry about issues like chalking and color fading.
- Polyester: If you want an affordable yet versatile coating option for cladding Galvalume, choose polyester. This material is derived from petroleum and is known for its quick-drying process. Protection against external elements and color retention effects are moderate. You can use it for industrial structures and warehouses where aesthetics are less important.
- Silicon-Modified Polyester (SMP): SMP is a highly durable coating that combines silicon and polyester resins to create a finish with excellent weather resistance. It retains its gloss for a long time and is suitable for commercial facades where visual impression is key.
How is Galvalume Cladding Installed?
Whether you are cladding galvalume on a commercial building or a residential one, you need to install it properly to maximize its benefits. Here are the steps for that:
Step 1: Proper Planning
You can’t just randomly install the cladding; instead, it needs proper planning. Start by assessing the building’s requirements. Does it need extra ventilation? Is there a warmth issue, so you need to focus on insulation? Also, review all local building codes before starting the project to avoid penalties later on.
Step 2: Collect Essential Tools
Now, you should start collecting key tools, including a tape measure, saws, shears, drills, and fasteners.
Step 3: Prepare the Site
Analyze the site carefully for damage and any other irregularities. If there are cracks, repair them right away before installing the new cladding. Also, clean all the dirt and debris to pave the way for secure attachment.
Step 4: Mark the Surface and Install the Framework
Measure the surface of the building that needs covering and mark points where galvalume will be installed. Then, attach vertical and horizontal furring strips to the building wall. The framework must be properly balanced and fastened securely to accommodate the cladding galvalume system.
Step 5: Attach Galvalume Panels
The installation of galvalume panels should start from the bottom of the framework and go all the way upwards. Double-check that each panel fits within the drawn marks, and tighten with screws or rivets. Continue attaching panels and, depending on the system, maintain alignment and proper connection.
Step 6: Seal the Joints and Edges
Once you are done with basic installation, apply sealants and flashing to make permanent connections. Flashing is important as it prevents moisture or water from getting in, protecting the cladding galvalume against damage and corrosion.
Before you leave, inspect the cladding galvalume for loose connections or joints. If needed, you can apply a protective coating to enhance its durability. Choose professional and reliable manufacturers, as they always provide warranties for products and back them with quality control certifications.
Note: Metal expands and contracts with temperature changes. We suggest using expansion joints so this movement doesn’t interfere with the installed galvalume.
Installation Considerations for Cladding Galvalume
When you are installing galvalume on the exterior of a building, you must be careful of the following things to avoid material damage and injuries:
- The clad galvalume must not come into direct contact with concrete or dissimilar metals, such as lead or copper, as this can initiate galvanic corrosion.
- Always use manufacturer-recommended fasteners and sealants for all junctions and laps to maintain weather resistance.
- Don’t use galvalume in harsh chemical environments, so it stays in top-notch condition for a long time. If you plan to install Galvalume panels on the walls, store them in a dry location, away from rain and moisture, to eliminate the risk of white rust.
- Handle all the sheets and panels with special equipment to avoid damage, and don’t drag them over each other, as this can cause scratches on the coating.
- Make sure the surface is well prepared, the substrate is laid out, and install the waterproof membrane as well as the cladding battens. They eliminate the risk of water pooling, ensuring your galvalume stays in good condition.
- Always wear proper safety gear, such as gloves, safety shoes, and helmets, to maintain safety during installation.
Applications of Galvalume Cladding
The applications of cladding galvalume are diverse; all hail the material’s unique functionality and aesthetics. Here’s an overview of some:
Commercial Buildings
Commercial buildings, including offices, towers, shopping malls, and warehouses, can utilize Galvalume due to its modern appearance and long lifespan.
Residential Buildings
Clients who want to enhance the curb appeal of their homes in a society can also opt for cladding galvalume.
Public Infrastructure
Train or bus stations, airports, and even public waiting areas can utilize galvalume cladding, especially because of its unique colors and versatility.
Why Do Galvalume Cladding?
Cladding galvalume has become a popular choice for modern buildings because it offers a mixture of performance, sleek appearance, and affordability. The following are the reasons you should opt for this solution:
- Superior Durability: Galvalume combines aluminum and zinc layers that protect the metal against rust and corrosion. With proper maintenance, it can last anywhere between 30 and 50 years, which ensures a good ROI.
- Improves Property Value: Nowadays, buyers seek homes with modern amenities and structure. Installing galvalume on a building significantly enhances its value, allowing the selling of the property at a higher price.
- Energy Efficiency: Cladding galvalume also lowers energy bills since it reflects sunlight, so there’s no heat absorption, helping the building stay cooler and reducing load on air conditioning systems.
For proper maintenance, clean the panels using a mild detergent and inspect for signs of wear and tear. If the galvalume had a coating, whether polyester or PVDF, reapply it every few years to keep the material looking clean.
