Ariel Plastics 25mm Clear Corolite CST Iron Profile 13/3" Twinwall Corrugated Polycarbonate Sheet

Ariel Plastics 25mm Clear Corolite CST Iron Profile 13/3" Twinwall Corrugated Polycarbonate Sheet

The Ariel Plastics 25mm Clear Corolite CST Iron Profile 13/3" Twinwall Corrugated Polycarbonate Sheet is a lightweight yet robust roofing and cladding solution designed for projects where strength, natural light and durability are important. Its twinwall construction provides increased rigidity and spanning capability compared with a standard single-layer corrugated sheet, while the clear finish allows plenty of daylight to pass through.

Twinwall Construction for Added Strength

Manufactured with a 2.5mm twinwall structure, the Corolite CST combines the inherent resilience of polycarbonate with the additional strength and rigidity provided by its internal twinwall design. This makes the sheet easy to handle while offering increased spanning capability for suitable roofing and cladding applications. The 3" Iron corrugated profile gives the sheet a practical, traditional appearance and makes it suitable for a variety of outdoor structures.

Clear Finish and UV Protection

The optically clear finish provides excellent natural light transmission, with the clear sheet allowing approximately 79% light transmission. This makes it particularly useful for applications where you want to create a bright, naturally lit space without completely enclosing the area. Co-extruded UV protection helps the sheet resist the effects of prolonged exposure to weather and sunlight, supporting its long-term performance in outdoor environments.

Versatile Roofing and Cladding Applications

Corolite CST twinwall polycarbonate sheets can be used across a wide range of projects. Typical applications include pergolas, patio covers, carports, greenhouses and screens. The combination of low weight, impact resistance and straightforward installation makes the sheets practical for both new structures and refurbishment projects. The sheets are suitable for roof pitches from a minimum of 5° up to a maximum of 90°, providing flexibility for different project designs.

Available Sheet Sizes

The Ariel Plastics Corolite CST range is available in three sheet lengths: 1830mm, 2440mm and 3050mm. Each size features the same clear finish, 3" Iron corrugated profile and 2.5mm twinwall construction, allowing you to select the length that best suits your project. The overall sheet width is 1060mm, providing a practical coverage format for a range of roofing and cladding applications.

Easy to Handle and Install

Despite its enhanced strength and rigidity, Corolite CST remains lightweight and easy to handle. Its practical construction makes cutting, positioning and installation more manageable, helping to simplify the installation process. The polycarbonate material is also resistant to damage and impact, making it a suitable choice for outdoor structures where durability is important.

Quality and Long-Term Performance

The Corolite CST sheet is designed to provide dependable performance in outdoor conditions and comes with a 10-year limited warranty. It is manufactured under a BS EN ISO 9001:2008 Quality Management System, supporting consistent manufacturing standards. The sheet also has a certified EN13501 fire rating, with certification available on request.

Roof Tiles & Fittings:
