8 mm multi-wall polycarbonate
8mm twinwall polycarbonate is a versatile choice for greenhouses and lightweight roofing when you need better rigidity than 4-6 mm options while keeping a strong price-to-performance ratio. The multiwall structure supports thermal insulation and diffuses light, helping maintain more stable growing conditions. The UV layer protects the sheets from sunlight, and the material remains easy to install and process, ensuring durability for years under typical use conditions.
8mm twinwall polycarbonate for greenhouses - stable covering and a solid performance compromise
8mm twinwall polycarbonate is a practical solution for seasonal and semi-seasonal greenhouses and lightweight enclosures where greater rigidity and better insulation than thinner sheets matter. The multiwall structure supports light diffusion and reduces heat loss, contributing to a more stable microclimate inside the structure.

Why 8mm twinwall polycarbonate works well in a greenhouse
An 8 mm thickness is a common choice when standard 4-6 mm sheets are too flexible for a given structure or support spacing. A stiffer sheet holds its shape better, and the air chambers improve insulation, making it easier to maintain more predictable conditions for plants. Polycarbonate is impact-resistant and does not crack like glass, so it handles everyday use well.
The UV layer reduces degradation caused by sunlight and helps keep the covering looking good for many seasons.
How to choose polycarbonate thickness for a greenhouse
Sheet selection depends on the type of structure, the spacing of arches or profiles, the surface area, and the insulation level you expect. 8mm twinwall polycarbonate is a good compromise when you want better stability and improved thermal performance without moving to significantly thicker options. Match the support spacing to the sheet thickness and the expected wind and snow loads.

8mm twinwall polycarbonate colours for greenhouses
On oteko.pl, 8mm twinwall polycarbonate sheets are available in several colours. Colour affects the amount of light inside the greenhouse and the internal temperature. Clear provides maximum light transmission, opal (milky) diffuses light and helps reduce overheating risk, while smoked variants can lower light intensity on the sunniest days.
UV layer and durability of 8mm sheets
Install the sheets with the UV-protected side facing outward, because it shields the material from sunlight and supports long-term durability and appearance. The twinwall polycarbonate available at Oteko.pl includes a UV layer, which reduces the risk of yellowing and degradation caused by the sun.
Installing 8mm twinwall polycarbonate in a greenhouse
Correct installation is crucial for airtightness and structural durability. Install the sheets with the UV side outward, with the chambers oriented vertically (for condensate drainage). Use H profiles for joining and U end profiles for closing, and protect the edges with breathable tape at the bottom and solid tape at the top to limit dirt buildup inside the chambers.
