SABS & CSIR Approved

 

Key Benefits

• No painting or ongoing maintenance required
• Waterproof & hail resistant
• Fire-resistant, UV resistant & corrosion-free
• Excellent heat and sound insulation
• Lightweight design (less structural load)
• Quick and easy installation
• Clean, modern finish (no visible screws)

 

What makes this system different?

 

The Roofing System is a next-generation 40 mm synthetic roofing solution designed to overcome common problems found in traditional roofing like IBR metal sheets and concrete tiles.

 

Unlike conventional roofing, where screws penetrate the surface and can cause leaks over time, this system uses a concealed-fix interlocking design.

 

• All screws are hidden beneath the roofing sheets
• This reduces the risk of water leakage and corrosion
• Creates a clean, seamless architectural finish

 

Advanced Material Technology

 

Manufactured using co-extruded ASA-PVC technology:

 

• ASA outer layer – protects against UV damage and colour fading
• Reinforced PVC core – provides strength and durability
• Offers long-term weather resistance and structural stability

 

Compared to Traditional Roofing

 

Vs IBR Metal Roofing:

• No rust or corrosion
• Reduced heat transfer (cooler interior)
• Less noise during rain
• No exposed screws (less leakage risk)

 

Vs Concrete Tiles:

• Much lighter (reduces roof load)
• Faster installation
• More resistant to cracking
• Better water resistance

 

How the System Works

The roof consists of:

• Starter Piece (Starter Plate)
• Main Interlocking Roofing Sheets

 

Each sheet locks into the next, covering all screws and forming a continuous, strong roofing structure instead of separate panels.

 

Installation Guidelines

 

Before Installation:

• Purlin spacing must be 600–800 mm
• Sheets must be cut to the full roof length
• ⚠️ No end-to-end joining or splicing allowed

 

Installation Steps

• Install Starter Piece
  • Secure onto purlins
  • Forms the base of the system
• Install First Sheet
  • Lock onto starter piece
  • Covers starter screws completely
• Fix Right Side of First Sheet
  • Secure with screws to base plate
  • Screws will be hidden by next sheet
• Install Next Sheet
  • Lock over previous sheet
  • Conceals screws and continues seamless finish
• Repeat for entire roof

 

Important Notes

• Sheets cannot be joined or overlapped mid-panel
• Incorrect joining may cause leaks and structural issues
• Handle carefully during transport and installation
• Do not step heavily on sheets before installation

 

Before installation: sheets are not load-bearing

 

After installation: system becomes a fully integrated, load-bearing structure with excellent strength and wind resistance

 

Ideal For

• Modern residential homes
• Commercial buildings
• Any project requiring durability, aesthetics, and low maintenance
