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

Attention 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 metal roof dedicated to single-slope ridge ventilation, equipped with high-level waterproof performance capable of withstanding severe storms accompanied by strong winds, such as large typhoons and guerrilla downpours. 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 outdoors, thereby preventing rainwater intrusion. Additionally, the Side Wing Ventilation Structure not only enhances waterproof performance but also improves attic ventilation through the wing effect harnessing wind power. 【Spacer-In Flat Method - Beautiful Finishing of the Wall Surface on One Side -】 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," there is no longer a need to visit the site twice for temporary and final installation of the ridge ventilation, allowing for a one-stop completion of the ridge ventilation installation.
