1. Introduction
In the past 48 hours, a surge in interest around sustainable and low-maintenance home exteriors has put metal cladding in the spotlight—especially as architects and builders increasingly specify corten steel facades and zinc clad roofs for modern residential projects. With rising demand for energy-efficient, long-lasting building envelopes, more homeowners are asking: ‘How do I properly install and care for a metal clad wall?’ Whether you’re building a new metal clad house or retrofitting an existing structure, this step-by-step guide gives you everything you need to know.
2. Understanding Metal Clad Basics
Before diving into installation, it’s important to grasp what ‘metal clad‘ actually means. The term ‘clad metal meaning’ refers to a composite material where one metal is bonded—often through rolling or electroplating—to another for enhanced performance. For example, aluminum clad steel combines the strength of steel with the corrosion resistance of aluminum. Similarly, stainless clad aluminum or titanium clad sheets offer specialized benefits for architectural use.
When used in construction, ‘metal clad’ typically describes exterior systems like metal clad siding, corrugated steel facades, or vertical standing seam metal siding. These systems can be made from various materials, including corten steel plate, zinc metal siding, copper siding, or Colorbond standing seam panels. Each offers unique aesthetics and durability profiles.
3. Choosing the Right Metal Clad Type for Your Project
Not all metal cladding is created equal. Your choice depends on climate, budget, and design goals.
- Corten steel siding provides a rustic, weathered look that stabilizes over time; however, corten siding cost can be higher than alternatives.
- Zinc facade panels are self-healing and ideal for sleek, modern designs like a zinc clad dormer or roof.
- Aluminum clad sheet (or aluminium clad sheet) is lightweight and corrosion-resistant—great for coastal areas.
- For traditional charm, consider exterior corrugated metal siding or metal weatherboard styles.
Also note compatibility: if you’re using PAC Clad products like PAC Clad coping, column covers, or HWP panels, ensure your fasteners and underlayment match manufacturer specs.
4. Step-by-Step Installation Guide
4.1. Prepare the Substrate
Ensure your wall framing is level, plumb, and covered with a proper weather-resistive barrier (WRB). Never install metal cladding directly over bare sheathing. Use furring strips if needed to create a drainage plane—critical for preventing moisture buildup behind your metal clad wall.
4.2. Measure and Cut Panels Accurately
Use metal sheet cutting tools like aviation snips or a circular saw with a metal-cutting blade. Always wear PPE. For precision, mark cuts with a straight edge. Common materials include 6061 T6 aluminum plate, 316 stainless steel plate, or mild steel plate—each requiring slightly different handling.
4.3. Install Starting Trim and First Panel
Begin at the bottom corner. Attach a starter strip or base flashing securely. Slide the first panel into place, ensuring it’s level. Fasten using corrosion-resistant screws compatible with your cladding type (e.g., stainless for copper or zinc).
4.4. Continue Panel Installation
For standing seam systems like vertical standing seam metal siding or PAC Clad standing seam roof panels, interlock seams carefully. For corrugated styles, overlap panels per manufacturer guidelines—usually 1–2 corrugations.
4.5. Seal Joints and Penetrations
Use butyl tape or compatible sealant at joints, around windows, and where the metal clad wall meets other materials. Avoid over-sealing; allow for thermal expansion.
5. Common Problems and How to Fix Them
5.1. Oil Canning (Waviness)
This visual distortion occurs when panels are over-tightened or lack proper support. Solution: Use closer furring strip spacing (max 16″ o.c.) and avoid overtightening fasteners.
5.2. Rust or Staining
Even clad metals can corrode if scratched or improperly installed near dissimilar metals. Prevent galvanic corrosion by using isolation membranes between aluminum and steel components.
5.3. Noise During Rain or Wind
Metal clad roofs and walls can be noisy. Mitigate this with proper insulation—consider metal clad insulation or a sound-dampening underlayment beneath the cladding.
6. Maintenance Tips for Longevity
Metal clad exteriors are low-maintenance but not zero-maintenance. Rinse annually with water to remove salt, pollen, or debris. For tougher grime, use mild soap and a soft brush—never abrasive cleaners. Inspect fasteners and seals every 2–3 years. If repainting is needed (e.g., on steel clad inc products), use coatings rated for your specific metal type.
7. 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 corten steel siding, a zinc facade, or aluminum clad steel, following these steps ensures a professional, long-lasting result. With proper planning and care, your metal clad house will stand strong against the elements for decades.
