25mm Clear Multi-Wall Polycarbonate: Exceptional Strength and Insulation for Advanced Applications

25mm clear multi-wall polycarbonate sheets offer unparalleled structural strength and thermal insulation. Engineered for demanding applications, their advanced multi-wall construction provides superior energy efficiency, durability, and light transmission, making them a premium choice for both residential and commercial projects.

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

Features of 25mm Clear Multi-Wall Polycarbonate

• Exceptional Rigidity and Load Capacity: The 25mm thickness supports heavy loads and spans wider distances, making it ideal for large-scale projects.
• Unmatched Thermal Insulation: The multi-wall design reduces heat transfer, offering a U-value of 1.7 W/m²·K, ideal for energy-efficient applications.
• Weather and Impact Resistance: Designed to withstand extreme weather conditions, these sheets are highly durable and resistant to impacts.
• UV Protection: A co-extruded UV layer shields the material from yellowing and degradation caused by prolonged sun exposure, ensuring long-lasting clarity.
• Excellent Light Transmission: Allows up to 60% of natural light to pass through, creating well-lit environments without harsh glare.

Applications of 25mm Clear Multi-Wall Polycarbonate

Conservatories and Sunrooms

The advanced insulation and robust construction make these sheets ideal for conservatories and sunrooms, creating comfortable environments year-round.

Industrial Roofing and Glazing

Perfect for large-scale industrial projects, 25mm multi-wall polycarbonate provides durable, insulating, and impact-resistant roofing and glazing solutions.

Covered Walkways and Canopies

These sheets offer long-lasting weather protection for walkways and canopies, with the structural strength to endure heavy loads and extreme conditions.

Commercial and Agricultural Buildings

From warehouses to agricultural structures, these sheets deliver superior insulation and strength for a wide range of applications.

Span and Support Recommendations for 25mm Multi-Wall Polycarbonate Sheets

When planning your project, it's crucial to consider the span capabilities of 25mm polycarbonate sheets. Without additional support, rafters can typically be spaced at 1,650mm. For enhanced stability, the use of cross bracing (also known as noggins or dwangs) can increase the allowable span to approximately 1,850mm, depending on load conditions and project requirements.

For applications requiring even wider spans, consider integrating additional support systems to meet structural demands. Incorporating cross bracing is particularly beneficial in areas prone to heavy snowfall or high winds, ensuring maximum stability and performance.

Installation Tips

To achieve optimal results, use compatible profiles and fixings to securely fasten the sheets and ensure a watertight seal. Proper framing and sealing are essential for maintaining thermal efficiency and preventing water ingress. Tailor the rafter spacing and supports to the specific requirements of your project for the best outcome.

In conclusion, 25mm clear multi-wall polycarbonate sheets are the ultimate solution for projects requiring superior insulation, durability, and structural integrity. Whether for roofing, glazing, or other demanding applications, these sheets provide exceptional performance and long-term reliability.
