Water and air management for durable structures
- Ensure water drainage under the terrace
- Limit water splashes on facades
- Improve natural ventilation (convection effect)
- Protect sensitive areas (thresholds, facades, perimeters)
- Contribute to the durability of the structure
- Offer a technical and aesthetic finish
Technical specifications
Grad® ventilation grilles are designed to ensure simultaneous water and air management within terraces and sensitive areas.
As true technical elements of the structure, they effectively evacuate water, limit splashes on facades, and ensure optimal ventilation under the structure.
They thus contribute to the overall durability of the terrace while providing a clean and controlled finish.
Designed to integrate perfectly with the Grad® system, they adapt to various construction configurations, including complex areas such as patio door thresholds or terrace perimeters.

The product from every angle
WATER MANAGEMENT
Efficient drainage and protection of sensitive areas.
CONTROLLED VENTILATION
Optimized air circulation for a healthy and durable structure.
SYSTEM INTEGRATION
Full compatibility with Grad® solutions for reliable implementation.
Ventilation, drainage and facade protection
The Grad® ventilation grille is an anodized aluminum board designed to optimize ventilation under terraces, ensure water drainage, and protect facades against splashes. Available in 119 mm and 155 mm widths, it integrates perfectly with Grad® rail systems to guarantee performance, durability, and discretion.
Efficient ventilation
Thanks to its perforations, the grille promotes natural convection
under the terrace:
– Air enters at the bottom,
– circulates under the structure,
– exits at the top.
Result: improved terrace longevity and
moisture evacuation.
Anti-splash for facades
Installed at the base of the wall, the grille significantly reduces splashes caused by rain and ensures efficient drainage under the terrace, thereby protecting facades from dirt and moisture.
Water drainage
Thanks to its strategic positioning between the terrace and the facade or at the base of a bay, the board promotes drainage and ensures efficient water flow, even during intense rainy periods.
Easy access under the terrace
Used as access hatches, the ventilation boards provide discreet and practical access to equipment located under the terrace. They facilitate inspection, servicing, or maintenance operations while ensuring the aesthetic continuity of the decking.
Anti-slip surface
The upper surface features a texture that improves grip underfoot. This finish is particularly suitable for patio door thresholds and high-traffic areas, where it contributes to user safety by reducing the risk of slipping.
