[Total Performance No.1 Product] New construction method for a beautiful finish on wall surfaces! Metal roof and decorative slate combined ridge ventilation.
"Katayanagare Soukai" is a new construction method that does not directly fix to the wall, resulting in a beautiful finish. It is a cost-effective ridge ventilation system that can be used with both metal and slate materials. Thanks to the newly developed patented structure "Large Water Stop Plate Slide Structure," it allows for the use of decorative slate and metal roofing materials, effectively reducing product inventory and preventing installation errors on site. Additionally, the "new construction method" that does not directly fix to the wall eliminates waviness during installation, resulting in an outstanding aesthetic appearance.
