The Polycarbonate Sheet 4mm Solid Bronze is the perfect choice for projects that require maximum durability, high transparency, and reliable weather protection. These certified solid polycarbonate sheets feature double-sided UV protection and come with a warranty of up to 10 years, ensuring long-term performance and resistance. Thanks to their robust structure, they are virtually unbreakable, providing safety and peace of mind in every application. The 4mm solid bronze polycarbonate sheets are ideal for waterproofing and covering pergolas, entrances, gazebos, greenhouses, and many other spaces, while maintaining the natural brightness of the area and creating a pleasant, light-filled atmosphere. Their versatility allows them to be installed in combination with other materials (e.g., reed panels, fabric, or wooden elements), offering both shading and waterproofing. The dual UV resistance prevents damage from solar radiation, minimizes yellowing, and significantly extends the sheet’s lifespan. Lightweight yet strong, they are easy to install without burdening the overall structure, while remaining resistant to time and temperature fluctuations. Suitable for both residential and professional use, the 4mm solid bronze polycarbonate sheet delivers the perfect balance of strength, protection, and aesthetics, making it a valuable investment that enhances both the practicality and the style of any space.

For the correct installation of polycarbonate solid sheets:
The canopy must necessarily have a certain slope so that the water can drain
There is no question of placement on the correct side, because the sheets offer protection from ultraviolet UV radiation on both sides
The protective films of polycarbonate sheets should be removed shortly before, during, or shortly after their installation, because their prolonged exposure to the sun affects them, resulting in them not detaching from the material
For the correct storage of polycarbonate solid sheets:
If they are not used immediately, they should be stored in a place that is not exposed to direct sunlight
Otherwise - and especially if left horizontally on cement slabs or similar materials - high temperatures develop, resulting in their warping
