Twinwall polycarbonate sheet

Twin wall polycarbonate sheets, also known as corflute polycarbonate, are a type of double-layered polycarbonate panel. They offer several advantages over solid polycarbonate panels being lighter in weight, more rigid, and more cost-effective. Polycarbonate twinwall are widely used in applications such as greenhouse panels, pergola roofing, pergola enclosures, pool enclosures, and more. These panels permit natural light transmission and provide effective heat insulation.

Excelite double wall polycarbonate panels are versatile and suitable for a variety of applications, such as pergola roofing, pergola side enclosure, greenhouse. Two layers structure of polycarbonate, creating a tougher it's rigid that can be used for applications like barriers, partitions, or roofing material. Available in a range of colors and sizes, our twinwall polycarbonate roofing are not only practical and durable but also affordable, making them an excellent option for numerous applications. As your reliable supplier, we will help you choose from various sizes and thicknesses to match your insulation and project requirements.

Features of Twinwall polycarbonate

• Lightweight: Twinwall polycarbonate roofing is much lighter than solid flat polycarbonate, 10mm twin wall polycarbonate sheet has a weight of 1.7kg/sqm, whereas a 10mm flat polycarbonate sheet weighs 12kg/sqm, and a 10mm glass sheet has a weight of 24.93kg/sqm.
• Rigidity: The rigidity of Polycarbonate twinwall is attributed to their unique structure, which consists of two layers of polycarbonate separated by air channels or walls.
• Thermal Insulation: The air channels between the layers of polycarbonate act as insulation, providing good thermal properties. This makes twin-wall polycarbonate an excellent choice for applications like greenhouses, where temperature control is crucial.
• Light Transmission: polycarbonate twinwall allow light to pass through while diffusing it, which can help protect plants from excessive sunlight. The diffused light also reduces the risk of hot spots which can burn the plants.
• Affordability: More affordable than flat polycarbonate, making it an attractive option for the projects when a balance of cost and performance is desired.

Common applications include:

• Greenhouses: The material's combination of light transmission and insulation properties makes it ideal for creating controlled environments for plant growth.
• Pergola Roofing: twin wall roofing can be used to cover pergolas, providing shade and protection from the elements while allowing natural light to filter through.
• Pergola Enclosure: When used for pergola enclosures, it offers protection from wind, rain, and insects while still providing visibility and natural light.
• Pool Enclosures: often used to create enclosures around swimming pools, offering protection from weather and debris without sacrificing natural light.
• Skylights: It can be used for skylights in commercial and residential buildings, bringing natural light into interior spaces.
• Sound Barriers: In some cases, twin wall sheets are used as sound barriers along highways and other noisy areas.

Keep in mind that while twinwall polycarbonate offers many advantages, it may not be suitable for every application. Solid polycarbonate sheets are still preferred when maximum transparency or higher impact resistance is required. The choice between these materials should be based on the specific needs of your project.

Twin wall polycarbonate vs solid polycarbonate sheet

They are two different types of polycarbonate materials with distinct characteristics, and they are suitable for various applications. Here's a comparison between the two:

1, Structure: Dual wall polycarbonate consists of two layers of polycarbonate separated by air channels, creating a multi-wall design. This design provides thermo insulation properties. Solid throughout without any air channels. They are a single-layer material.

2, Weight: It is lighter in weight compared to flat polycarbonate, making it easier to handle and install. Flat polycarbonate weight is about 5-7 times heavier.

3, Rigidity: As rigid as solid polycarbonate, it is still relatively rigid, offering good strength and stability. Twin wall sheets exhibit minimal sagging over time, even under their own weight or when subjected to external loads. It can go bigger span than flat polycarbonate.

4, Insulation: Dual wall polycarbonate provides excellent thermal insulation due to the air channels, making it suitable for applications where temperature control is important, such as greenhouses.

5, Cost friendly: Double layer polycarbonate sheet use much less material per sqm, so it's more cost-effective.

6, Light transmission:  Clear flat polycarbonate panels provide a glass-like appearance and can achieve 92% light transmission (LT), making it ideal for applications where clear vision is essential, such as in windows, skylights, or safety barriers.

Multi-wall polycarbonate panels offer a translucent appearance with a light transmission of around 85%, making them suitable for applications that prefer to diffused light.

7, UV Resistance: Both polycarbonate roofing materials have good UV rating, which makes them suitable for outdoor applications.

8, Strength: When comparing a 10mm corflute sheet with compact polycarbonate, it's clear that solid polycarbonate offers greater strength and durability. Solid flat polycarbonate is a better choice heavy-duty applications like pergola roofing, especially in Melbourne harsh weather.

Twin wall roofing, including corflute, often has a thinner top layer than solid polycarbonate. Over time and with exposure to the sun, this thinner top layer can be damaged by hails. Therefore, for a long-lasting and robust pergola roofing solution, solid polycarbonate is the preferred option.

The choice between twin wall and solid polycarbonate depends on the specific needs of your project. Talk to an expert today to discuss your specific application needs.
