Introduction

Whether you’re building a carport, conservatory, or patio cover, choosing the right glazing bars and accessories is essential for a secure, long-lasting polycarbonate roof solution. At Areco, our premium glazing systems are engineered for performance, durability, and ease of installation.

Why Glazing Bars Matter

Polycarbonate roofing sheets need stable, weather-proof support — and that’s where glazing bars come in. Designed to hold multiwall and solid sheets securely, quality glazing bars:

• Improve load bearing and wind resistance
• Ensure watertight seals
• Create a clean aesthetic finish

Areco’s glazing bars accommodate popular thicknesses from 10mm to 25mm and are available in multiple finishes for visual appeal.

Types of Glazing Bars Available

At Areco you’ll find:

Rafter Supported Glazing Bars

• Ideal for traditional roof installations
• Lightweight aluminium with PVC caps
• Easy leak-proof installation

Self-Supporting Glazing Bars

• Free-span up to 4 metres — ideal for lean-to roofs
• Built-in wall plates and locking bars
• Strong performance without extra rafters

All systems include precision engineered end caps, gasket sealing and snap-fit accessories for a professional finish.

Pro Tips for Choosing Your Glazing System

• Match the glazing bar type to your application (lean-to vs supported roof)
• Choose the correct sheet thickness compatibility
• Confirm finish colour to integrate with roofing aesthetics
