1. Introduction
In the past 48 hours, a major construction trend has emerged: architects and homeowners alike are increasingly turning to metal clad exteriors for their durability, modern aesthetics, and sustainability. According to a report by Building Design+Construction (June 2024), orders for corten steel siding and zinc clad roofs have jumped by 32% year-over-year, driven by climate resilience concerns and rising interest in low-maintenance facades. If you’re considering a metal clad house or already have one, knowing how to install and maintain it properly is key to maximizing its lifespan and visual appeal.
2. Understanding Metal Clad Basics
Before diving into installation, it’s important to grasp what ‘metal clad’ actually means. The metal clad meaning refers to a building surface—wall, roof, or structure—covered with a layer of metal for protection, insulation, or design. Clad metal meaning often involves bonding two or more metals (like aluminum clad steel or stainless clad aluminum) to combine strength, corrosion resistance, and cost-efficiency. Common types include metal clad siding, standing seam facade panels, and corrugated steel facade systems.
3. Choosing the Right Metal Cladding Material
Not all metal cladding is created equal. Your choice depends on climate, budget, and design goals.
- Corten steel siding offers a rustic, weathered look and is ideal for modern homes—but be aware of corten siding cost, which can run $8–$15 per sq. ft.
- Zinc metal siding and zinc clad dormer systems provide excellent longevity and a sleek gray finish that ages gracefully.
- For budget-friendly options, consider exterior corrugated metal siding or colorbond standing seam panels.
- Copper siding and titanium clad are premium choices with unmatched durability but come at a higher price point.
Also consider practical factors: aluminum clad pipe insulation may be needed for utility penetrations, while pac clad column covers or pac clad coping can add architectural detail.
4. Step-by-Step Installation Guide
4.1. Prepare the Substrate
Ensure your wall or roof structure is level, dry, and properly insulated. Use metal clad insulation behind panels if thermal performance is a priority. Install a vapor barrier if required by local code.
4.2. Measure and Cut Panels
Use metal sheet cutting tools (shears or a circular saw with a metal-cutting blade) to size your panels. Whether you’re working with aluminum clad sheet, stainless steel plate, or 1/8 inch steel plate, always wear protective gear. For vertical standing seam metal siding, precision is critical to avoid gaps.
4.3. Install Furring Strips (If Needed)
For metal clad wall systems, furring strips create an air gap that improves drainage and reduces condensation—especially important for steel facade or corrugated steel facade applications.
4.4. Attach the Cladding
Start at the bottom and work upward. Secure panels with corrosion-resistant fasteners. For pac clad standing seam roof systems, use hidden clips to maintain a clean look. With metal weatherboard or standing seam siding, overlap panels correctly to prevent water intrusion.
4.5. Seal Joints and Penetrations
Use compatible sealants around windows, doors, and utility lines. If running metal clad electrical wire through an exterior wall, ensure proper grommets and weatherproof fittings are used to maintain the envelope’s integrity.
5. Common Problems and Solutions
5.1. Rust or Corrosion
Even clad metals like aluminum clad stainless steel can corrode in harsh coastal environments. Solution: Choose zinc coated or electroplated options (e.g., chromium electroplating) for added protection. Regularly inspect for scratches that expose base metal.
5.2. Oil Canning (Wavy Appearance)
This occurs when large flat metal panels flex. Solution: Use stiffer alloys (like 6061 T6 aluminum plate) or add more support ribs during installation.
5.3. Thermal Expansion Noise
Metal expands and contracts with temperature, causing creaking. Solution: Allow for movement with slotted fastener holes and proper panel spacing.
5.4. Poor Drainage Leading to Staining
Especially common with corten steel plate. Solution: Install drip edges and ensure proper slope on metal clad roof systems like zinc clad roof or pac clad hwp profiles.
6. Maintenance Tips for Longevity
Maintaining your metal clad house doesn’t have to be labor-intensive:
- Rinse panels annually with water to remove salt, pollen, or pollutants.
- Inspect sealants and fasteners every 2–3 years.
- Avoid abrasive cleaners on finishes like copper siding or stainless metal sheet.
- For metal nameplates or decorative elements (e.g., brass plates for engraving), use mild soap and soft cloths.
7. Conclusion
Installing and maintaining a metal clad house exterior is a smart investment in durability and design. Whether you opt for a corten steel facade, zinc clad roof, or aluminum clad steel siding, following proper techniques ensures your metal clad building stands strong for decades. With the right materials—from alloy plate to pac clad column covers—and routine care, your metal clad home will look striking and perform flawlessly in any climate.
