Multiwall polycarbonate 6 mm is a durable, UV-protected glazing material designed for residential greenhouses, terrace covers, and light-transmitting structures. This sheet offers a balanced combination of structural stability and natural light, ensuring your outdoor spaces remain bright and protected throughout the seasons.

Why Choose This Thickness
This variant is engineered for those who need a reliable, manageable material for DIY installations. Its weight ensures it stands up well to daily weather exposure without becoming overly cumbersome to handle during assembly.
The 6 mm profile is specifically developed to handle real-world challenges, offering a significant upgrade in impact resistance over thinner, less robust plastic sheeting. It is a practical choice for homeowners who value longevity.
Installation and Compatibility
These sheets are custom-cut to your specific measurements, making them a versatile fit for various frame types. For the best results, we recommend protecting the open ends of the channels with sealing tape to keep the interior clean and clear.
If you are planning a larger project, you might also consider our 16 mm clear sheet for increased insulation. Always ensure your rafter spacing is properly aligned to support the panel width for a secure, long-lasting finish.
Important information

- 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.
Use cases and compatibility
This thickness is an excellent choice for residential greenhouses and terrace covers where you need a balance of structural rigidity and high natural light transmission for plants.
If you require superior thermal insulation for year-round heating, consider opting for a thicker 16 mm sheet to further reduce heat loss in your structure.
Ensure your rafter spacing is compatible with this 6 mm sheet to maintain stability against snow loads and wind pressure during extreme weather conditions throughout the year.
