What is a Polycarbonate Roofing Sheet?

A polycarbonate roofing sheet is a high-performance thermoplastic roofing material known for its exceptional strength and transparency. It is impact-resistant, UV-protected, and lightweight. The material can withstand harsh weather conditions such as strong winds, extreme sun, and heavy rainfall. These features make it ideal for Kenya’s varied climate zones. It is suitable for Nairobi’s high-altitude sun as well as the hot coastal regions like Mombasa and Malindi.

The increasing demand for modern, affordable roofing alternatives has boosted the popularity of polycarbonate sheets. They are among the most sought-after roofing materials in the country. This is especially true for their durability and long-term cost savings.

Types of Polycarbonate Roofing Sheets in Kenya

When choosing a polycarbonate roofing sheet in Kenya, the two most popular types are:

1. Twin Wall Polycarbonate Sheet

Twin-wall polycarbonate sheet, also known as hollow polycarbonate sheet, consists of two thin layers separated by internal ribbing. This structure creates air gaps that provide insulation. It is ideal for projects requiring heat control and light diffusion.

Key Advantages:

• Excellent insulation (keeps spaces cooler)
• Lightweight and easy to install
• High light diffusion
• Strong impact resistance
• Cost-effective for large areas

Best Applications:

• Greenhouses
• Carports
• Awnings
• Walkways
• Shade structures

2. Solid Polycarbonate Sheet

Solid polycarbonate sheet, also known as compact polycarbonate sheet, is a single, strong layer resembling glass but 250 times stronger. It offers crystal-clear visibility and maximum strength while remaining lighter than glass.

Key Advantages:

• Extremely strong and virtually unbreakable
• Maximum transparency
• High UV resistance
• Great for security and premium installations

Best Applications:

• Balcony roofing
• Skylights
• Security glazing
• Pergolas
• High-end commercial projects

Available Colors of Polycarbonate Sheets in Kenya

Polycarbonate roofing sheets come in beautiful colors that match different architectural needs. Gypsum Ceiling Supplies Ltd distributes the following color options:

• Clear – Best for maximum light transmission

• Bronze – Popular for carports and pergolas

These colors help you control heat, reduce glare, and create a visually appealing finish for any installation.

Standard Size: 5.8m x 2.1m

All polycarbonate roofing sheets supplied by Gypsum Ceiling Supplies Ltd come in the widely accepted international standard size of 5.8m x 2.1m. This size provides excellent coverage for both small and large projects and helps reduce material wastage.

Benefits of Using a Polycarbonate Roofing Sheet in Kenya

Using polycarbonate sheets offers a long list of advantages:

1. Lightweight and easy to transport
2. UV-protected surface prevents yellowing and damage
3. High impact resistance (up to 200–250 times stronger than glass)
4. Long lifespan and weather resistance
5. Modern and elegant appearance
6. Energy-efficient thanks to heat-insulating properties
7. Affordable compared to traditional roofing materials

These qualities make polycarbonate sheets one of the best materials for modern roofing applications in Kenya today.

How to Install a Polycarbonate Roofing Sheet in Kenya (Step-by-Step)

Correct installation is key to ensuring durability and maximum performance. Here is a clear, step-by-step guide that homeowners and contractors can follow:

Step 1: Prepare Your Roofing Framework

Ensure the supporting structure is secure and level. Use steel or timber beams spaced appropriately, depending on sheet thickness. For twin-wall sheets, maintain narrow spacing to prevent sagging.

Step 2: Measure and Cut the Sheets

Use a fine-tooth saw or grinder to cut the sheet to the required length. Always remove the protective film only after installation is complete.

Step 3: Ensure UV Side Faces Up

All high-quality polycarbonate sheets have a UV-protected side. Ensure the labeled UV side faces the sun to prevent damage and yellowing over time.

Step 4: Drill Expansion Holes

Polycarbonate expands and contracts with temperature changes. Drill holes slightly larger than the screw diameter to allow movement and prevent cracking.

Step 5: Fix Using Self-Drilling Screws with Rubber Washers

Secure the sheets using screws fitted with rubber washers. The washers prevent water leakage and reduce pressure on the sheet.

Step 6: Use H-Chanel connectors

Use H-channel connectors in the appropriate colors to tightly connect two sheets. Apply silicon clear in between the H channel connectors. This prevents leakage and increases structural stability.

Step 7: Seal the Edges

Use aluminum tape or U-profiles to seal open edges. This prevents dust, insects, and moisture from entering the hollow spaces.

Step 8: Install End Caps or Flashings

Finish with end caps or flashing profiles to protect edges and give the roof a neat, professional appearance.

Step 9: Peel Off Protective Film

Once installation is complete, remove the film carefully to avoid scratches.
