[5/22 Renewal] Ventilation for Metal Roofs 'Single Slope i-ROOF2'

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

The "Katanagare i-ROOF2" is the industry's first dedicated metal roof ridge ventilation system designed to withstand severe storms with strong winds, such as large typhoons and sudden heavy rain, featuring a high level of waterproof performance. The most significant feature of this renewal is the "Side Wing Ventilation Structure." This structure is adopted in all products of the series. Just as an airplane wing generates negative pressure through airflow, the side wings utilize wind power to create negative pressure, facilitating the flow of air from the attic to the outside and preventing rainwater intrusion. Additionally, the Side Wing Ventilation Structure not only enhances waterproof performance but also improves attic ventilation efficiency through the wing effect harnessing wind power. 【Spacer-In Flat Method - Achieving a Beautiful Finish on the Wall Side of the Single Slope -】 The "Spacer-In Flat Method," which has been well received in the Katanagare Soukai, is also adopted in the Katanagare i-ROOF2. This method, which uses "Wall Side Spacers," significantly enhances aesthetic appeal. The "Wall Side Spacers" provide support, suppressing the waviness on the wall side and resulting in a beautiful finish. Furthermore, by using "Wall Side Spacers," it eliminates the need for two site visits for temporary and final installation of the ridge ventilation, allowing for a one-stop installation process.
