Solid vs. Hollow Polycarbonate: Best Choices for Windy Areas and Car Shades
Polycarbonate sheets are increasingly popular in Kenya for roofing, carports, pergolas, and outdoor shelters. Lightweight, durable, and aesthetically versatile, polycarbonate is a practical alternative to glass and traditional roofing materials. However, when choosing polycarbonate for areas prone to wind or for car shades, selecting the right type—solid vs. hollow polycarbonate—is crucial for long-term performance.
This guide explores the differences, advantages, and applications of solid and hollow polycarbonate sheets, helping homeowners, contractors, and architects make informed decisions.
Understanding Polycarbonate Sheets
Polycarbonate is a thermoplastic material known for its:
-
High impact resistance (up to 250 times stronger than glass)
-
Lightweight structure
-
UV resistance to prevent yellowing
-
Flexibility for various roofing designs
Two primary types dominate the Kenyan market:
-
Solid Polycarbonate Sheets – Thick, single-layer sheets with excellent clarity and strength.
-
Hollow Polycarbonate Sheets – Multi-wall sheets with air gaps, providing insulation and lightweight properties.
You can explore a wide range of polycarbonate sheets in Kenya and learn about their applications for residential and commercial projects.
Solid Polycarbonate Sheets: Features and Benefits
Solid polycarbonate sheets are essentially transparent panels similar to acrylic but far stronger. They are ideal for structures where clarity, durability, and wind resistance are priorities.
Key Features
-
Thickness ranges from 2mm to 12mm, depending on the application
-
Excellent impact resistance, even in harsh weather
-
High light transmission, perfect for natural lighting
-
Can be used as a direct replacement for glass in skylights and canopies
Advantages for Windy Areas
Solid polycarbonate is rigid and can withstand strong gusts without bending or collapsing. Its uniform structure distributes stress evenly, making it ideal for:
-
Rooftops in windy locations
-
Car shades and pergolas
-
Outdoor shelters in exposed areas
Additionally, solid polycarbonate is easier to seal and fix to frames, reducing the risk of leaks during heavy storms.
Ideal Applications
-
Car shades in Nairobi, Mombasa, and Kisumu
-
Residential skylights
-
Commercial outdoor canopies
-
Transparent partitions in high-traffic areas

Hollow Polycarbonate Sheets: Features and Benefits
Hollow (multi-wall) polycarbonate sheets consist of two or more layers separated by internal air gaps. This design provides thermal insulation and reduces weight, making them a cost-effective option for various roofing projects.
Key Features
-
Lightweight and easy to install
-
Multiple thicknesses (commonly 4mm to 16mm)
-
Air gaps provide insulation against heat and noise
-
Flexibility for curved structures like pergolas or greenhouses
Advantages for Car Shades
Hollow polycarbonate sheets are excellent for shading cars because they reduce heat transmission while still allowing diffused light. Their lightweight nature makes installation simpler, especially for DIY projects or residential setups.
However, in extremely windy areas, hollow sheets can flex more than solid sheets, increasing the risk of damage if not properly supported with strong frames.
Ideal Applications
-
Carports in low to moderate wind zones
-
Garden pergolas
-
Greenhouses and indoor plant enclosures
-
Roofing where insulation is a priority

Solid vs. Hollow Polycarbonate: Comparing Performance
| Feature | Solid Polycarbonate | Hollow Polycarbonate |
|---|---|---|
| Wind Resistance | High, rigid, ideal for strong winds | Moderate, requires sturdy support |
| Impact Resistance | Very high | Good, but less than solid sheets |
| Weight | Heavier | Lightweight, easier to handle |
| Thermal Insulation | Low | High, air gaps reduce heat transfer |
| Cost | Higher | Lower, more budget-friendly |
| Applications | Car shades, roofing, skylights, exposed areas | Car shades, pergolas, greenhouses, insulation-focused roofing |
This table highlights that solid polycarbonate is preferred for windy areas, while hollow polycarbonate excels in insulation and lightweight applications.
Choosing the Right Polycarbonate for Your Car Shade
When planning a carport in Kenya, consider:
-
Local Wind Conditions – Solid polycarbonate performs better in coastal towns like Mombasa or high-altitude areas like Nakuru.
-
Budget and Installation – Hollow sheets are cost-effective and easier to handle, especially for DIY projects.
-
Aesthetic Preferences – Solid sheets offer clarity and modern finishes; hollow sheets provide a diffused light effect.
-
Frame Support – Hollow sheets require a robust frame to prevent bending under strong winds.
For expert advice and a range of options, BHD Kenya offers both solid and hollow polycarbonate sheets with nationwide delivery.
Installation Tips for Maximum Durability
-
Ensure proper framing with galvanized or steel supports for both solid and hollow sheets.
-
Use anti-UV screws and washers to prevent leaks.
-
Allow expansion gaps in solid sheets to accommodate temperature changes.
-
Regularly clean sheets with mild detergents to maintain clarity and performance.
