With the new 4-chamber polycarbonate profile, available in Solar and Alu-Solar versions, Grando expands its existing portfolio with a technically optimized solution for demanding swimming pool cover applications.
Improved Design with an Additional Fourth Chamber
The key innovation of the new profile is the integrated fourth chamber. This additional chamber specifically covers the tongue-and-groove connection area, completely hiding the previously visible connection area.
The result is not only a cleaner and more uniform appearance, but also clear functional advantages:
• Significantly reduced algae growth in the concealed area
• Less visible dirt accumulation thanks to the protected profile structure
This improves both the long-term appearance and the ease of maintenance of the cover system.
Proven Material Benefits Remain Fully Intact
Despite the advanced profile construction, the well-known advantages of polycarbonate profiles remain unchanged.
The new profile from Grando continues to offer:
• High impact resistance, including improved resistance to hail damage
• Excellent temperature resistance without risk of overheating or deformation under intense sunlight
This makes the profile ideal for outdoor use in changing weather conditions.
Compatible with Existing Systems
Another major advantage is its system compatibility.
The new 4-chamber profile has dimensions and buoyancy characteristics comparable to the existing 3-chamber profile. As a result, it can be integrated into already installed pool cover systems without requiring extensive modifications.
This allows existing Grando installations to be upgraded more easily and efficiently.
Cap-Tec Version as Standard
The profile is exclusively available in the Cap-Tec version.
This design features a specially welded and sealed end cap engineered for long-term watertightness. It also increases structural stability while preventing dirt and moisture from entering the profile ends.
Designed for Long-Term Performance
With the new 4-chamber polycarbonate profile, Grando introduces a solution that intelligently combines design, hygiene and long-term durability.
In particular, the concealed tongue-and-groove structure represents a significant improvement in terms of longevity and ease of maintenance, while fully preserving the proven advantages of polycarbonate technology.
