The Ultimate Guide to Polycarbonate Sheets for Roofing and Skylights

Polycarbonate Sheets

Why Polycarbonate Is the Future of Roofing

When it comes to modern roofing, property owners want materials that combine durability, style, and energy efficiency. Traditional options like metal or glass often fall short — they either corrode, shatter, or trap heat.

That’s where polycarbonate sheets step in. Known for their unbreakable strength and superior light transmission, they’ve become the preferred choice for everything from residential patios to commercial skylights.


At GB PLAS, we supply premium polycarbonate sheets engineered to deliver long-lasting protection, beauty, and performance for Malaysia’s tropical climate.

What Are Polycarbonate Roofing Sheets?

Polycarbonate roofing sheets are thermoplastic panels designed to be lightweight yet incredibly strong.

They provide up to 250 times more impact resistance than glass, while being significantly lighter — making them ideal for both roofing and skylight applications.

Types of Polycarbonate Roofing Sheets

  1. Solid Polycarbonate Sheets
    Clear and tough — ideal for skylights, canopies, and architectural glazing.

  2. Twin-Wall & Multi-Wall Sheets
    Feature an air gap between layers, offering superior thermal insulation and light diffusion.

  3. Corrugated Polycarbonate Sheets
    Designed for outdoor use — strong, weatherproof, and suitable for carports, walkways, and factories.

Key Advantages of Polycarbonate Roofing

1. Exceptional Durability

Polycarbonate roofing is virtually unbreakable, withstanding heavy rain, strong winds, and even hail. It won’t rust, crack, or corrode like metal or fiberglass.

 

2. UV Protection

All GB PLAS polycarbonate sheets are UV-coated to block harmful rays while allowing soft, natural light through — protecting both interiors and occupants.

 

3. Lightweight for Easy Installation

Weighing less than half of glass or metal, polycarbonate reduces structural load and speeds up installation time — saving both labour and transport costs.

 

4. Excellent Thermal Insulation

Twin-wall and multi-wall sheets help regulate temperature, keeping interiors cooler and reducing air-conditioning expenses.

 

5. High Light Transmission

Polycarbonate allows up to 90% light transmission, making it perfect for skylights, greenhouses, and covered patios that benefit from natural brightness.

 

6. Design Flexibility

Available in clear, tinted, frosted, and coloured options, polycarbonate roofing can complement both modern and traditional architectural styles.

 

7. Low Maintenance

Polycarbonate doesn’t rust or need repainting. A simple wash keeps it looking new — reducing maintenance costs over the years.

Applications of Polycarbonate Roofing

Polycarbonate sheets can be used in countless ways across industries:

  • Residential Homes: Skylights, carports, patios, pergolas.
  • Commercial Buildings: Covered walkways, shopfronts, awnings.
  • Industrial Facilities: Factory roofing, loading bays, shelters.
  • Agricultural Projects: Greenhouses, nurseries, and shade structures.
  • Public Infrastructure: Bus stops, stations, and community shelters.

Tips for Choosing the Right Polycarbonate Roofing

  1. Determine the Purpose – Choose solid sheets for clarity, twin-wall for insulation, and corrugated for outdoor coverage.

  2. Check for UV Coating – Ensures resistance to yellowing and sun damage.

  3. Select the Right Thickness – Thicker sheets provide better strength and insulation.

  4. Pick the Finish – Clear for maximum light, tinted for heat control, frosted for privacy.

  5. Buy from a Trusted Supplier – Ensure ISO-certified quality and reliable warranty coverage.
