4mm Clear Twinwall Polycarbonate: Versatile and Durable Glazing Solution

4mm clear twin-wall polycarbonate sheets are a lightweight, impact-resistant alternative to traditional glass, offering superior thermal insulation and UV protection. Their unique twin-wall structure provides enhanced strength and durability, making them ideal for various applications.

We offer standard maximum sheet sizes of 5m x 2.1m. However, for larger projects, sheets up to 7m x 2.1m are available upon request. Please note that custom sizes may require additional delivery time. Contact us via phone or email for a quote.

Key Properties of 4mm Clear Twinwall Polycarbonate

  • Lightweight and Easy to Handle: These sheets are significantly lighter than glass, facilitating easy installation and reducing structural load.
  • High Impact Resistance: With up to 200 times the impact resistance of glass, they are highly durable and less prone to breakage.
  • Superior Thermal Insulation: The twin-wall design creates an insulating air gap, improving energy efficiency by reducing heat loss.
  • UV Protection: A co-extruded UV layer on one side prevents yellowing and degradation from sun exposure, ensuring longevity.
  • Excellent Light Transmission: Allowing up to 82% light transmission, they provide ample natural light while diffusing harsh sunlight.

Common Applications of 4mm Clear Twinwall Polycarbonate

Greenhouse Glazing

Ideal for greenhouse panels, these sheets offer high light transmission and thermal insulation, creating optimal growing conditions.

Shed Windows and Porch Enclosures

Their lightweight nature and durability make them perfect for shed windows and porch enclosures, providing clarity and resilience.

Cold Frames and Cloches

Enhance plant protection with these sheets, which offer excellent insulation and light diffusion for cold frames and cloches.

Office Partitions and Interior Glazing

Create modern office partitions that allow natural light flow while maintaining privacy, thanks to their clear yet sturdy structure.

DIY Projects

Versatile and easy to cut, they are suitable for various DIY projects requiring a durable, transparent material.

Installation Considerations

While 4mm twin-wall polycarbonate is suitable for various applications, it's essential to ensure proper installation to maintain its structural integrity and longevity. For roofing projects, consider using thicker sheets (e.g., 10mm) for added rigidity and weather resistance.

In summary, 4mm clear twin-wall polycarbonate sheets offer a versatile, durable, and energy-efficient solution for multiple glazing needs, combining the clarity of glass with enhanced strength and insulation properties.

“Very impressed this time around!!! (disappointed with communication and delivery in first lockdown) and left a negative review which I updated after delivery. I can now understand all the good reviews before the pandemic. Still the cheapest by far and the products are spot on. I've just placed another order - Thank you keep up the good work”
