1. Introduction
Just 48 hours ago, a viral post on ArchDaily showcased a striking new residential project in Austin, Texas: a minimalist metal clad house wrapped in corten steel siding that weathers beautifully over time. The design sparked massive interest in durable, low-maintenance exteriors—especially as homeowners seek sustainable alternatives to traditional wood or vinyl. If you’re considering a metal clad house or already own one, knowing how to properly install and maintain it is key to longevity and curb appeal.
In this guide, we’ll walk you through a step-by-step process for installing and caring for your metal clad wall, roof, and other exterior elements—whether you’re using corrugated steel facade panels, vertical standing seam metal siding, or a zinc clad dormer. We’ll also troubleshoot common problems like rust, poor insulation, and electrical wiring compatibility.
2. Understanding Metal Clad Meaning and Materials
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 a base metal (like steel or aluminum) is bonded with a protective or decorative outer layer—such as copper, zinc, or stainless steel. This creates ‘clad metals’ that combine strength, corrosion resistance, and aesthetic flexibility.
- Common types include aluminum clad steel, stainless clad aluminum, titanium clad sheets, and copper nickel clad panels.
- Popular choices for residential use: corten steel siding, zinc metal siding, colorbond standing seam, and PAC CLAD standing seam roof systems.
3. Step-by-Step Installation of a Metal Clad House
3.1. Choose the Right Metal Clad Type
Start by selecting the appropriate metal for your climate and design goals. For humid or coastal areas, opt for aluminum clad steel or stainless steel plate. In urban settings, a corten steel facade offers a bold, industrial look that develops a protective rust patina. For roofs, consider a zinc clad roof or PAC CLAD HWP for superior weather resistance.
3.2. Prepare the Substructure
Ensure your wall or roof framing is level, dry, and properly insulated. Use metal clad insulation behind the panels to improve energy efficiency—especially critical for metal clad buildings in extreme temperatures. Don’t forget vapor barriers to prevent condensation behind the metal.
3.3. Install the Cladding Panels
For vertical standing seam metal siding or corrugated steel facade panels, begin at the bottom and work upward. Secure panels with hidden fasteners or snap-clad clips to avoid water intrusion. Use PAC CLAD coping and column covers for clean transitions at edges and corners.
- Always leave expansion gaps (typically 1/8 inch) between panels to accommodate thermal movement.
- Seal all joints with compatible sealants rated for metal-to-metal contact.
3.4. Handle Electrical and Utility Penetrations
When running utilities through a metal clad wall, use metal clad electrical wire (also called MC cable) with proper fittings. Aluminum clad wire or cu clad wire must be connected to junction boxes using listed MC connectors. Never force cables through sharp edges—use grommets to prevent sheath damage.
4. Common Problems and Maintenance Tips
4.1. Rust and Corrosion
Even clad metals can corrode if scratched or exposed to salt. Inspect your metal clad siding annually. For minor rust on corten steel siding, simply rinse with water—the patina will self-heal. For aluminum or zinc surfaces, clean with mild soap and avoid abrasive tools.
4.2. Poor Insulation or Condensation
If your metal clad house feels drafty or shows interior moisture, check your metal clad insulation. Upgrade to high-R-value batts or rigid foam, and ensure the air barrier is continuous behind the metal.
4.3. Fading or Chalking
Painted systems like Colorbond may fade over time. Repaint using metal-specific primers and topcoats. Unpainted options like zinc facade or copper siding age gracefully and rarely need recoating.
5. Cost Considerations
Corten siding cost typically ranges from $8 to $15 per square foot installed, while standard corrugated metal siding starts around $4/sq ft. Although upfront costs are higher than vinyl, metal clad houses offer 50+ year lifespans with minimal upkeep—making them cost-effective long-term.
6. Conclusion
Installing and maintaining a metal clad house doesn’t have to be intimidating. By choosing the right clad metals—like aluminum clad sheet, corten steel plate, or PAC CLAD systems—and following proper installation and care practices, you’ll enjoy a sleek, durable, and energy-efficient home for decades. Whether you’re building new or re-cladding an existing structure, metal cladding offers unmatched versatility and modern appeal.
