basic information
■Can be used for fire-resistant buildings. It has obtained a 75-minute quasi-fire-resistance structure certification. Even in fire-resistant buildings, it enables smooth attic ventilation and roof ventilation. Additionally, the 75-minute quasi-fire-resistance structure notification requires two layers of reinforced gypsum board (total thickness of 46mm or more) under the eaves, but this product has obtained certification with only the ventilation material, eliminating the need for eaves materials. ■Achieves ventilation while maintaining the continuity of the fireproof covering line. The sides of the ventilation material are equipped with holes for exterior wall ventilation. By maintaining the continuity of the fireproof covering line during a fire, it demonstrates fireproof performance, while during normal conditions, it secures an exterior wall ventilation pathway, contributing to the longevity of wooden houses. Furthermore, by placing the holes for attic ventilation at the eaves, it accommodates exterior materials with a maximum thickness of 45mm. ■Rainproof has been verified! Can be safely installed around the entire roof. It can be safely installed even on the water side and eaves side of the roof, where rain and wind are likely to enter. Wind-driven rain tests have been conducted, confirming high waterproof performance. Additionally, a wide variety of fittings tailored to the roof shape are available. *To comply with the ministerial certification number, please refer to the installation manual and detail drawings, and carry out the installation according to the contents of the ministerial certification document.
