1. Introduction
In the past 48 hours, architects and builders across North America have been buzzing about the surge in demand for sustainable, low-maintenance exteriors—especially metal clad systems. With rising interest in modern aesthetics and climate resilience, homeowners are increasingly turning to metal clad wall solutions like corten steel siding, zinc facade panels, and colorbond standing seam systems. Whether you’re building a new metal clad house or upgrading an old one, knowing how to properly install and maintain your metal cladding is key to longevity and performance.
Metal clad isn’t just a trend—it’s a smart investment. From corrugated steel facade designs to sleek vertical standing seam metal siding, these materials offer durability, fire resistance, and striking visual appeal. But without proper handling, even the best clad metals can underperform. This guide gives you step-by-step instructions to get it right the first time.
2. Choosing the Right Type of Metal Clad
Not all metal clad is created equal. The term ‘metal clad meaning’ refers broadly to any construction material where a base metal is bonded or coated with another metal for enhanced properties—this is also known as ‘clad metal meaning.’ Popular options include:
- Corten steel siding: Rustic, self-protecting finish; ideal for modern industrial looks. Note: corten siding cost varies but typically runs $7–$12 per sq. ft.
- Zinc metal siding: Naturally patinas over time; great for eco-conscious builds.
- Aluminum clad steel: Lightweight, corrosion-resistant, and often used in pac clad standing seam roofs.
- Copper siding: Premium look with long-term value; develops a green patina.
- Exterior corrugated metal siding: Budget-friendly and widely available.
Also consider compatibility with other systems—like aluminum clad pipe insulation for HVAC or metal clad electrical wire for outdoor circuits. For structural elements, materials like 1/4 steel plate or stainless steel plate may be needed behind cladding for support.
3. Preparing the Wall Surface
Before installing any metal clad wall system, ensure your substrate is clean, dry, and structurally sound. Remove old siding, repair sheathing, and install a weather-resistant barrier (WRB) like housewrap. This prevents moisture intrusion behind panels—a common cause of premature failure.
If you’re working on a metal clad building retrofit, check local codes for vapor barriers and insulation requirements. Many professionals pair metal siding with metal clad insulation to improve energy efficiency. Don’t forget flashing around windows, doors, and penetrations—pac clad coping and column covers integrate seamlessly with most systems.
4. Installing Metal Clad Siding Step by Step
Follow these steps for a professional-grade installation:
- Measure and cut panels using metal sheet cutting tools (e.g., aviation snips or a circular saw with a metal-cutting blade). Always wear safety gear.
- Start at the bottom corner. Use a level to ensure your first panel is plumb.
- Fasten with corrosion-resistant screws designed for metal. Avoid over-tightening—metal expands and contracts with temperature.
- For standing seam systems like pac clad hwp or colorbond standing seam, use hidden clips to allow movement.
- Overlap panels according to manufacturer specs—typically 1–2 inches for corrugated styles.
- Seal joints and edges with compatible sealants, especially around dormers (e.g., zinc clad dormer details).
Pro tip: When installing vertical standing seam metal siding, leave a small gap at the top and bottom to accommodate thermal expansion.
5. Common Problems and How to Fix Them
Even high-quality clad metals can face issues if installed or maintained poorly:
- Rust spots on corten steel? That’s normal—but if rust appears on non-corten steel, it means the protective coating failed. Clean with a mild acid solution and repaint with metal-compatible paint.
- Loose panels? Caused by improper fastening or wind uplift. Re-secure with longer screws into solid framing.
- Condensation behind siding? Likely due to missing or damaged WRB. Add ventilation or retrofit a rainscreen gap.
- Fading or chalking? UV exposure affects some finishes. Choose PVDF-coated products for better longevity.
For electrical work near cladding, remember that metal clad electrical wire (like aluminum clad steel wire or cu clad wire) must be properly grounded and protected when penetrating walls.
6. Maintenance Tips for Longevity
Metal clad siding is low-maintenance but not zero-maintenance. Rinse annually with a garden hose to remove dirt and pollutants. For tougher grime, use mild soap and a soft brush—never abrasive pads.
Inspect fasteners and seals every 2–3 years. Replace corroded screws with stainless steel versions. If you have a steel facade near coastal areas, rinse more frequently to prevent salt buildup.
Don’t pressure-wash—high PSI can dent thin panels or force water behind seams. And if you ever need to repaint, use paints formulated for metal substrates to avoid peeling.
7. Conclusion
Installing and maintaining metal clad siding doesn’t have to be complicated. By selecting the right type—whether it’s a corten steel facade, zinc clad roof, or aluminum clad sheet—and following proper techniques, you’ll enjoy a stunning, durable exterior for decades. As sustainable design continues to dominate 2024’s construction trends, metal clad remains a top choice for both aesthetics and performance.
