High Performance Multiwall Polycarbonate Sheet Identity
The Arla Multiclear BOX 2Wall is a high-quality multiwall polycarbonate sheet 4 mm designed for demanding outdoor applications. It features a robust 800 g/m² mass for superior impact resistance and weather durability. This clear sheet includes one-sided UV protection to maintain light transmission and material integrity over time.
Solving Structural Weakness in Greenhouse Glazing
Many standard glazing materials suffer from premature degradation and low impact resistance, leading to frequent replacements. Lightweight alternatives often fail to withstand environmental stress, resulting in cracked panels and poor insulation.
Our 800 g/m² multiwall polycarbonate sheet 4 mm provides a high-density solution that resists weather fluctuations and physical impact. By choosing this premium material, you ensure a durable, energy-efficient structure that maintains clarity and strength for years.

Important information
- 15-Year Warranty Includes a 15-year warranty against yellowing, ensuring high light transmission throughout this period.
- Cutting Tolerance The maximum allowable cutting deviation on the edges is 4 mm.
- Standard Width The standard sheet width is 2.1 m. If a sheet is cut down to 1.05 m, one edge will remain open due to the internal channel structure.
- Internal Structure The internal design (channels shape) of the sheets may vary based on stock levels, but the technical specs are identical. We never mix different structures in the same order to ensure a uniform look.
- UV Protection & Installation Polycarbonate sheets must be installed with the UV-protected side facing up (facing the outside) for the protection to work. The UV side is clearly marked on the protective film.
- Handle with Care Handle the sheets carefully to prevent scratches and damage.
- Storage Store in a cool, dry place away from direct sunlight.
