What Is the Thickness of Sunlight Sheets?
The thickness of sunlight sheets varies depending on the internal structural design. Different structures are engineered to achieve different levels of strength, insulation performance, and load-bearing capacity, which directly determines their thickness limits.
- 2-Layer Twinwall Sheets
For standard 2-layer twinwall polycarbonate sheets, the maximum available thickness is 12 mm. This structure is widely used for general roofing, greenhouse applications, and basic daylighting systems where lightweight performance and cost efficiency are key considerations.
- 3-Layer Twinwall Sheets
For 3-layer structures, the maximum thickness can reach 16 mm. Compared to 2-layer sheets, this structure provides improved thermal insulation and enhanced rigidity, making it suitable for applications requiring better energy efficiency and moderate load resistance.
- 4-Layer Twinwall Sheets
For 4-layer polycarbonate twinwall sheets, the thickness can go up to 20 mm. This multi-wall structure offers stronger mechanical performance, better insulation, and higher durability, making it suitable for more demanding architectural and industrial applications.
- Special Structures (Honeycomb / X-Type Sheets)
For advanced structural types such as honeycomb sheets or X-type sheets, the maximum thickness can reach 25 mm. These reinforced structures are designed for high-strength applications requiring superior load-bearing performance and enhanced thermal insulation.
