Greenhouses rely on the right covering to provide light, warmth, and protection. Polycarbonate sheets are now the preferred material for many greenhouse builders in Sri Lanka, offering better performance than glass or plastic film.
At Jeewa Plastic, we supply a variety of polycarbonate sheets suited for greenhouse use. Here’s why they are ideal.
Light Diffusion for Healthier Growth
Polycarbonate sheets allow light to enter while diffusing it evenly across your plants. This:
- Reduces hotspots and plant burn.
- Provides more uniform growth.
- Maximizes daylight hours, even during cloudy weather.
Our Solux Twinwall Sheets offer excellent light transmission and soft diffusion, ideal for seedlings and mature plants.
Insulation Keeps Temperatures Stable
Unlike glass, polycarbonate sheets trap heat efficiently. Twinwall and multiwall types offer natural air insulation between layers. This:

- Maintains warmth during cool nights.
- Reduces heating costs in colder climates.
- Extends the growing season for sensitive crops.
For insulation and light control, 6mm Solux Twinwall Sheets are a reliable choice.
UV Protection Built In
Polycarbonate sheets at Jeewa Plastic include UV-coated surfaces. Benefits include:
- Protection for plants from harmful rays.
- Extended sheet lifespan with less yellowing or cracking.
- Better clarity over time.
Look for UV-protected options like Xanlite Polycarbonate Sheets, available in clear and light-diffusing varieties.

Strength and Durability for All Weather
Polycarbonate sheets are lightweight but impact-resistant. They withstand:
- Heavy rain and wind.
- Occasional debris or falling branches.
- Long-term outdoor exposure.
Compared to glass, they are safer and easier to install. This makes them ideal for both small garden greenhouses and large-scale farm projects.
Easy Installation and Maintenance
Polycarbonate is easy to cut, shape, and secure. It requires minimal support structures and can be cleaned with simple soap and water. Regular maintenance includes:
- Checking seals for tightness.
- Cleaning surface dust to maintain clarity.
- Inspecting for scratches or damage seasonally.
