1. Introduction
In the past 48 hours, a surge in sustainable home design has spotlighted metal clad exteriors as a top choice among architects and eco-conscious homeowners. With rising demand for durable, low-maintenance facades—especially corten steel siding and zinc clad roofs—many are turning to metal cladding not just for aesthetics but for resilience against extreme weather and climate change impacts.
If you’re considering a metal clad house or upgrading your current exterior, this step-by-step guide will help you install and maintain metal clad walls correctly. Whether you’re working with corrugated steel facade panels, vertical standing seam metal siding, or aluminum clad sheet systems, these practical tips ensure a professional finish that lasts decades.
2. Understanding Metal Clad Meaning and Materials
Before diving into installation, it’s important to grasp what ‘metal clad’ really means. The term ‘clad metals’ refers to composite materials where a base metal (like steel or aluminum) is bonded with a more corrosion-resistant layer—such as stainless steel, copper, or zinc. This process enhances durability while keeping costs manageable.
Common types include:
- Corten steel siding: Known for its rust-like appearance that stabilizes over time, ideal for modern metal clad buildings.
- Zinc metal siding and zinc clad dormer: Offers self-healing properties and a sleek matte finish.
- Aluminum clad steel or aluminium clad sheet: Lightweight and resistant to salt air, perfect for coastal homes.
- Copper siding and stainless clad aluminum: Premium options with unique patinas and high longevity.
Always verify the ‘clad metal meaning’ when sourcing materials—some products labeled ‘metal clad‘ may simply be painted rather than truly layered composites like aluminum clad stainless steel or titanium clad sheets.
3. Preparing for Installation
Proper prep prevents 90% of future issues. Start by checking local building codes—especially if you’re using metal clad electrical wire nearby or integrating metal clad insulation.
Gather these essentials:
- Measuring tape and level
- Corrosion-resistant fasteners (stainless steel or coated)
- Underlayment or moisture barrier
- Compatible flashing (e.g., PAC CLAD coping or column covers for edges)
- Appropriate tools for cutting metal sheet (snips, nibbler, or plasma cutter for thick steel plate)
Ensure your wall structure can support the weight of your chosen system—steel plate or diamond plate steel adds significant load compared to lightweight aluminum diamond tread plate.
4. Step-by-Step Installation of Metal Clad Wall Panels
Follow these steps for a clean, watertight installation:
4.1. Install a drainage plane. Attach a breathable housewrap or rigid insulation board to create an air gap behind the cladding. This prevents moisture buildup and improves energy efficiency—critical when using metal clad insulation.
4.2. Mount furring strips vertically every 16–24 inches. Use treated wood or corrosion-resistant metal channels to provide a secure nailing surface and allow airflow.
4.3. Begin at the bottom. Install starter trim, then secure the first panel with hidden clips (for standing seam systems like Colorbond standing seam or PAC CLAD HWP) or exposed fasteners (for exterior corrugated metal siding).
4.4. Overlap panels correctly. For corrugated or ribbed profiles, ensure side laps align with manufacturer specs—usually 1–2 corrugations. Use sealant only if recommended; many modern systems rely on mechanical seals.
4.5. Cut panels cleanly. Use metal sheet cutting tools to avoid burrs. For intricate shapes (e.g., around windows), score and snap aluminum sheet for sale or use a jigsaw with a metal-cutting blade for stainless steel plate.
4.6. Finish edges with trim. Use PAC CLAD column covers, corner guards, or custom-bent flashing to seal joints and enhance aesthetics.
5. Maintenance and Troubleshooting
Metal clad walls are low-maintenance but not zero-maintenance. Here’s how to keep them looking great:
- Rinse annually with water to remove dirt and pollutants—especially important for zinc facade and copper siding, which rely on natural oxidation.
- Inspect fasteners yearly. Loose screws can lead to panel movement and leaks.
- Touch up scratches on painted systems like Colorbond promptly to prevent rust on the underlying steel.
- For corten steel siding cost concerns: remember that initial investment pays off—corten requires no painting and develops a stable rust layer in 2–5 years.
Common problems and fixes:
- Oil-canning (waviness in flat panels): Minimize by using stiffer gauge material or adding intermediate supports.
- Galvanic corrosion: Never directly join dissimilar metals (e.g., aluminum clad steel next to copper). Use dielectric separators.
- Thermal expansion noise: Allow for movement with slotted holes or floating clip systems in standing seam facade installations.
6. Conclusion
Installing a metal clad wall isn’t just about looks—it’s a smart investment in durability, sustainability, and curb appeal. Whether you choose a rugged corten steel plate, a refined zinc clad roof, or sleek vertical standing seam metal siding, following these steps ensures your metal clad house stands strong for generations. Always prioritize quality materials like those from reputable suppliers (e.g., Steel Clad Inc.) and consult professionals for complex designs involving alloy clad or stainless steel checker plate accents.
