High Performance 20mm Multiwall Polycarbonate Sheets
The Arla Multiclear 5X multiwall polycarbonate sheet 20 mm is a premium glazing solution designed for maximum thermal efficiency. It features a multi-layer structure that provides significant impact resistance and long-term UV protection. This clear sheet is engineered to balance light transmission with superior heat retention for energy-efficient structures.
Superior Insulation for Demanding Climate Conditions
Standard glazing materials often struggle to maintain internal temperatures in cold climates, leading to high energy costs and limited seasonal use. Thin sheets fail to provide the necessary thermal barrier required for year-round comfort.
Our 20mm multiwall polycarbonate solves this by utilizing a thick, multi-layer design that delivers a U-value of 1.8 W/m²*K. This construction effectively traps heat, making it the ideal choice for industrial roofs, terrace covers, and greenhouses where climate control is essential.

Versatile Applications and Structural Compatibility
These sheets are highly recommended for industrial roofing projects requiring maximum insulation and structural strength. They are also perfectly suited for terrace roofs and outdoor shelters where energy efficiency is a priority. Additionally, they serve as an excellent glazing option for greenhouses located in colder regions where heat retention is vital.
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.
