1. Introduction
In the past 48 hours, a surge in sustainable home construction has spotlighted metal clad houses as a top trend among eco-conscious builders. With rising demand for durable, low-maintenance exteriors, materials like corten steel siding, zinc clad roofs, and vertical standing seam metal siding are dominating architectural showcases from Austin to Portland. If you’re considering a metal clad house—or already own one—this guide will help you install and maintain it like a pro.
Metal cladding isn’t just industrial-looking—it’s versatile, weather-resistant, and increasingly stylish. Whether you’re working with a corrugated steel facade, a pac clad standing seam roof, or aluminum clad sheet panels, understanding the basics can save time, money, and headaches down the line.
2. Understanding Metal Clad Meaning and Types
Before diving into installation, it’s key to grasp what ‘metal clad’ actually means. In simple terms, metal clad refers to any structure—wall, roof, or even pipe—that’s covered or sheathed in a layer of metal for protection, aesthetics, or both. This includes everything from metal clad electrical wire to full-scale metal clad buildings.
Common types you’ll encounter include:
- Corten steel facade (known for its rust-like appearance and structural strength)
- Zinc metal siding (elegant, self-healing patina over time)
- Copper siding (luxurious but pricey)
- Colorbond standing seam (pre-painted, corrosion-resistant steel)
- Exterior corrugated metal siding (classic, cost-effective look)
- Aluminum clad steel (lightweight yet strong, often used in wall panels)
Each type offers unique benefits, so choose based on climate, budget, and design goals. For example, corten siding cost may be higher upfront, but its longevity offsets maintenance expenses.
3. Step-by-Step Installation of a Metal Clad Wall
Installing a metal clad wall properly ensures weather-tight performance and visual appeal. Here’s how to do it right:
First, prepare the substrate. Your wall must be structurally sound, level, and covered with a moisture barrier like housewrap. Never attach metal directly to bare wood or concrete without proper underlayment.
Next, install furring strips vertically every 16–24 inches. These create an air gap that improves drainage and reduces condensation—critical for long-term performance of your metal clad wall.
Then, begin panel installation from the bottom up. Use stainless steel fasteners compatible with your cladding material (e.g., avoid carbon steel screws with aluminum to prevent galvanic corrosion). For standing seam systems like pac clad hwp or vertical standing seam metal siding, follow manufacturer specs for clip spacing and seam engagement.
Don’t forget flashing! Integrate pac clad coping at roof-wall intersections and pac clad column covers around structural elements to prevent water intrusion.
4. Installing a Metal Clad Roof
A metal clad roof—whether zinc clad roof, colorbond standing seam, or corrugated steel—requires precision. Start by ensuring your roof deck is clean, dry, and meets local load requirements.
Lay down an appropriate underlayment (synthetic or ice-and-water shield in cold climates). Then, install starter strips along the eaves.
For standing seam systems, use hidden fasteners to avoid puncturing the panel surface. With exposed-fastener systems like exterior corrugated metal siding, align screws with the crest of each rib and use neoprene washers to seal holes.
Always allow for thermal expansion—especially with longer runs of aluminum clad sheet or steel plate. Leave small gaps at end laps and use slotted holes where needed.
5. Maintenance and Common Problem Fixes
One major perk of a metal clad house is low maintenance—but it’s not zero maintenance. Here’s how to keep it looking great:
Clean annually with mild soap and water. Avoid abrasive cleaners that can scratch finishes like those on stainless steel plate or aluminum diamond tread plate.
Inspect seams and fasteners twice a year. Tighten loose screws and replace any that show signs of corrosion—common culprits include incompatible metals like aluminum clad stainless steel in salty coastal air.
If you notice rust on corten steel siding, don’t panic—it’s part of the intended patina. But if rust appears on non-weathering steel (like mild steel plate), sand and repaint immediately to prevent spread.
For dents in metal weatherboard or metal clad siding, small ones can often be gently tapped out from behind. Larger damage may require panel replacement—keep spare pieces on hand.
6. Safety and Code Considerations
When working with metal clad electrical wire or aluminum clad pipe insulation, always follow NEC (National Electrical Code) guidelines. In Pennsylvania and many other states, metal clad wiring is permitted in commercial buildings—but only when installed correctly with proper grounding and box connectors.
For structural elements, verify local building codes regarding wind uplift, fire ratings, and snow loads—especially if using thinner gauges like 1/8 inch steel plate or 3mm aluminium checker plate.
7. Conclusion
A metal clad house blends modern aesthetics with rugged durability. Whether you opt for a sleek steel facade, a rustic corten steel plate wall, or a reflective zinc clad dormer, proper installation and routine care will ensure decades of performance. With rising interest in sustainable architecture—and materials like alloy clad panels gaining traction—you’re not just building a home; you’re investing in the future.
