Slate roof surface ventilation "Roof surface ventilation unit"

Attention residential designers! The "roof ventilation unit" has been renewed with improved performance! It demonstrates reliable waterproof capabilities even during short, heavy rains like those from a sudden downpour.

This product is a ventilation unit suitable for roofs where ridge ventilation cannot be installed. In addition to waterproofing against wind and rain, we have newly developed a structure called "Double Ventilation Structure" that can demonstrate reliable waterproof performance even in cases of heavy rain falling in a short period, such as during a guerrilla downpour, and have upgraded the waterproof performance of the "roof surface ventilation unit." *Patent pending. The all-in-one product design means fewer components and easy installation. **What is Double Ventilation Structure?** It consists of two ventilation components, "Upper Ventilation" and "Under Ventilation," each exhibiting a certain level of waterproof and ventilation performance. By combining these two components, it achieves a higher and more stable waterproof and ventilation performance. **Features** - Reliable waterproof performance even in heavy rain in a short period, such as guerrilla downpours. - Reliable waterproof performance even in typhoon-level storms, passing a spray and wind test with a rainfall rate of 240mm per hour and wind speed of 30m/s. - Industry-leading ventilation performance as an attic ventilation component that can be installed even on narrow roofs in urban areas. *For more details, please contact us or check the link below (official website).
