Roof Ventilation Grille New Teppei(R)

On gable roofs in the Kanto and western Japan regions.

The overwhelming ventilation volume that expels heat and humidity brings the temperature of the attic closer to the outside temperature, and the dehumidifying effect keeps the wood of the structure constantly dry, thereby suppressing the occurrence of mold and decay. Additionally, it prevents rain and snow from blowing in with three layers of blocking, making it particularly effective in regions west of Honshu where rain and wind are strong.

[5/22 Renewal] Ventilation for Metal Roofs "Rain Stop i-ROOF2"

Attention all residential designers! The popular product "i-ROOF" has been fully remodeled and is being re-released.

The "Rain Stop i-ROOF 2" is the industry's first dedicated rain stop ventilation for metal roofs, designed to withstand severe storms accompanied by strong winds, such as large typhoons and sudden heavy rains, with a high level of waterproof performance. 【Side Wing Ventilation Structure】 The most significant feature of this renewal is the "Side Wing Ventilation Structure." This structure, adopted in all products of the series, enhances ventilation performance by creating a flow that generates negative pressure from the airflow over the wings, allowing air to be expelled from the attic to the outside. Additionally, the Side Wing Ventilation Structure not only improves ventilation performance but also prevents rainwater from entering the attic by utilizing the wing effect of wind. 【Dual Ventilation Structure - Achieving 60% Increased Ventilation while Maintaining Reliable Waterproof Performance】 The "Dual Ventilation Structure" (patent pending) provides double waterproofing through upper and under ventilation, successfully balancing the trade-off relationship between waterproof performance and ventilation performance. ● For more details, please contact us or check our company website.
