Why Choose This Opal Finish
The opal tint is a smart choice for anyone looking to soften the light under a patio cover. It eliminates the glare often found with clear sheets while maintaining a bright, airy feel.
Because these sheets are UV-protected on one side, they resist discoloration and maintain their structural integrity over time. It is a reliable, low-maintenance option for stylish, modern outdoor living.
Installation and Compatibility
These sheets are custom-cut to your specific measurements, making them a flexible choice for various framing systems. For the best results, we recommend using sealing tapes to protect the channel ends from debris and moisture. If you are planning a larger structure, you might also consider our 10 mm clear sheets for increased thermal efficiency.
Important information
- 10-Year Warranty Covers discoloration caused by weather, as well as loss of impact resistance and light transmission.
- Cutting Tolerance The maximum allowable cutting deviation on the edges is 4 mm.
- 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.

Use cases and compatibility
This sheet is ideal for residential pergolas and patio covers where you want to reduce glare while maintaining a bright, private, and comfortable outdoor living space.
If your primary goal is maximum thermal efficiency for a heated greenhouse, consider opting for a thicker 10 mm sheet to improve overall heat retention.
Ensure your rafter spacing is compatible with 6 mm sheets to handle local snow and wind loads effectively, and always remember to seal the channel ends properly.
