Clay tile ridge ventilation "Elegant + (Plus)"

Reliable rain protection with high waterproof performance! Achieved through a double ventilation structure.

"Elegant + (Plus)" is a product that allows for ridge ventilation for clay tiles. Conventional products maintained waterproof performance with a deflector structure, but by adopting a double ventilation structure with upper and lower ventilation components, we achieved higher water-stopping performance than conventional products. Furthermore, by eliminating the deflector that was present in "Elegant," the appearance of the finished product has significantly improved, along with enhanced workability and safety. 【Features】 ■ High waterproof performance with double ventilation structure for reliable rain protection ■ Improved design, workability, and safety ■ Increased ventilation volume ■ Product design focused on user needs ■ Fire-resistant specifications available as an option for semi-fireproof areas *For more details, please contact us or check the link below (our company website).

High Ventilation Swing for Slate Singles

【A must-see for residential designers!】 A 'shocking specification' that overturns industry norms with a new structure that promotes ventilation and enhances waterproofing effects.

The "High Ventilation Swing" is a ventilation component for decorative slate and single roofs that accommodates gable and hip roof shapes. In recent years, due to the effects of global warming, such as the occurrence of large typhoons and sudden heavy rains, high performance is required for roofs in Japan. This product achieves a high level of two opposing performances: a reliable "high waterproof performance" that can withstand stormy weather, and a "high ventilation performance" that allows ventilation even with short ridges, such as those found on hip roofs. (Developed by our company using the "Side Wing Ventilation Structure" (patent pending)) 【Features】 - Waterproof performance that is reliable even in stormy weather at the level of large typhoons → Passed a very rigorous spray and wind test with a rainfall rate of 240mm per hour and wind speed of 40m/s - Sufficient ventilation performance even with short ridges → Achieved an industry-leading effective opening area of 438cm² (1P) - Significantly improved workability for roof installation → Achieved over three times the workability compared to our conventional products 【Side Wing Ventilation Structure】 - Utilizes the power of the wind to create negative pressure with the side wings, creating a flow that expels air from the attic to the outside, preventing rainwater intrusion. - The wing effect utilizing wind power improves the ventilation performance of the attic. *For more details, please contact us or check the link below.

Japan Housing News Featured Article "All About Ventilation and Airflow" *Free Distribution

In 2016, I had a conversation with Professor Saito from Ashikaga University (then Ashikaga Institute of Technology) about "Ventilation and Airflow," which was serialized in the Japan Housing News (6 installments).

In wooden houses, the ventilation and air circulation of the structure is considered important, yet it poses many problems. Professor Hiroaki Saito from Ashikaga University, who is conducting training on design methods for building envelopes that include energy conservation and durability, has provided a simple and easy-to-understand explanation of the basics of structural ventilation and air circulation, using real examples over six sessions. <Content> Vol.1 The Necessity of Ventilation and Air Circulation Vol.2 Attic Ventilation Vol.3 Case Study 1: Problems Due to Poor Ventilation Vol.4 Case Study 2: Problems Due to Poor Ventilation Vol.5 The Necessity of Ventilation in Lower Roofs Vol.6 Modern Living Environments and Ventilation

[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.

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 power. 【Improved Design Aesthetics with Less Prominent Ridge Ventilation】 The old products had a step in the ridge ventilation area, making it stand out, but the Side Wing Ventilation Structure allows for the ridge ventilation area and the general ridge area to be installed at the same level without any steps. By making the ridge ventilation less noticeable, it results in a cleaner design. ● For more details, please contact us or check our company website.
