1. Introduction
In the past 48 hours, global design enthusiasts have been buzzing about the surge in metal-clad architecture featured at Milan Design Week 2024, where designers highlighted innovative uses of corten steel facade and zinc clad dormers in sustainable urban housing. This renewed spotlight underscores a growing trend: homeowners are increasingly choosing metal clad exteriors for their durability, low maintenance, and modern aesthetic. Whether you’re building a new metal clad house or retrofitting an existing structure, this step-by-step guide will help you navigate installation, material selection, and upkeep—without the guesswork.
2. Understanding Metal Clad: What It Really Means
Before diving into installation, it’s crucial to clarify what ‘metal clad’ actually means. The term ‘clad metal meaning’ refers to a composite material where one metal is bonded to another—often for enhanced corrosion resistance, strength, or cost efficiency. For example, aluminum clad steel combines the lightweight nature of aluminum with the structural integrity of steel. Similarly, stainless clad aluminum or titanium clad sheets offer specialized performance in extreme environments. In construction, ‘metal clad’ typically describes exterior systems like metal clad wall panels, metal clad roof systems, or metal clad siding used on residential and commercial buildings.
3. Choosing the Right Materials for Your Metal Clad House
Not all metal cladding is created equal. Your choice depends on climate, budget, and desired look. Popular options include:
- Corten steel siding: Known for its rust-like appearance that stabilizes over time; ideal for industrial or rustic designs. Note that corten siding cost can be higher upfront but offers decades of service with zero painting.
- Zinc metal siding or zinc clad roof: Self-healing surface forms a protective patina; excellent for coastal areas.
- Copper siding: Develops a green patina over time; premium choice with high longevity.
- Colorbond standing seam or PAC CLAD standing seam roof: Pre-painted, durable, and available in dozens of colors—great for modern homes.
- Exterior corrugated metal siding: Budget-friendly and quick to install; often used on metal clad sheds or farmhouses.
Also consider vertical standing seam metal siding for a sleek, contemporary facade, or corrugated steel facade for a bold, textured look. Always verify compatibility with local building codes—especially if using metal clad electrical wire or aluminum clad pipe insulation in conjunction with your exterior system.
4. Step-by-Step Installation Guide
4.1. Prepare the Substructure
Ensure your wall or roof framing is level, dry, and properly insulated. Use metal clad insulation behind panels to improve energy efficiency. For walls, install a weather-resistant barrier (like housewrap) before attaching furring strips to create an air gap—this prevents moisture buildup behind your metal clad wall.
4.2. Measure and Cut Panels Accurately
Use proper tools like metal snips or a circular saw with a metal-cutting blade for clean cuts. When working with materials like aluminum clad sheet or stainless steel plate, wear safety gear—metal edges can be sharp. For precision, mark measurements clearly and double-check before cutting.
4.3. Install Starting Strips and First Panel
Begin at the bottom corner of your wall or eave line for roofs. Secure starter strips with corrosion-resistant fasteners. Attach the first panel using hidden clips for standing seam systems (like PAC CLAD HWP) or exposed screws for corrugated styles. Ensure panels are plumb and aligned.
4.4. Continue Panel Installation
Overlap panels according to manufacturer specs—typically 1–2 inches for corrugated, or interlock seams for standing seam. Use PAC CLAD coping or column covers for transitions around windows, doors, or corners. Avoid over-tightening screws, which can distort thin-gauge metal.
4.5. Seal and Flash Critical Areas
Apply sealant at joints, penetrations, and roof-wall intersections. Use compatible flashing materials—zinc or copper work well with matching siding. This step is vital to prevent leaks in your metal clad building.
5. Common Problems and Maintenance Tips
Even the best-installed metal clad house needs occasional care. Watch for these issues:
- Oil-canning (waviness in flat panels): Minimize by using stiffer gauges or adding stiffeners during install.
- Galvanic corrosion: Occurs when dissimilar metals touch (e.g., aluminum clad steel next to copper). Always use isolation barriers or compatible metals.
- Scratches or fading: Most pre-finished systems like Colorbond resist this, but touch-up paint may be needed over time.
Maintenance is simple: rinse annually with water, inspect fasteners for looseness, and clear debris from roof valleys. Unlike wood or vinyl, metal clad siding won’t rot, warp, or require repainting.
6. Conclusion
Installing a metal clad house is a smart investment in durability, sustainability, and style. From selecting the right clad metals—whether it’s corten steel plate, zinc clad dormer panels, or aluminum diamond tread plate accents—to executing a precise installation, every step contributes to a long-lasting exterior. With proper planning and attention to detail, your metal clad building will stand strong against the elements while turning heads for years to come.
