  These are also known as twin-wall or multi-wall sheets. They are made with hollow channels or walls that provide additional strength and rigidity while keeping the sheets lightweight. They have a high strength-to-weight ratio and are incredibly robust and lightweight. They have excellent thermal insulation properties because of their multi-wall structure. Additionally, they are available in various configurations, including twin-wall, triple-wall, and even more wall structures, depending on the desired strength and thermal properties. They are commonly used for applications such as conservatories, carports, and insulated glazing.

• Solid Polycarbonate Sheets:

  Solid polycarbonate sheets are made from high-quality polycarbonate resin in an energy-efficient way. They have a thicker design, making them more robust and offering higher optical clarity. These sheets have excellent impact resistance and durability and are suitable for applications requiring maximum strength. They are also available in various thicknesses and sizes. Applications include security glazing, bulletproof windows, and industrial machine guards.

• Embossed/Structured Polycarbonate Sheets:

  These sheets have specific patterns or textures pressed into their surface. The patterns can be clear, frosted, or textured, depending on the desired aesthetic and functional properties. They offer aesthetic versatility because of their decorative surfaces. The patterns can scatter light, reducing glare and increasing privacy. They are also used in lighting fixtures, where diffusing light is important.
