Profile

[Company strength]
Our products protect the inside of houses from moisture and high temperature, and therefore are indispensable for maintaining the strength of the roofs and walls of wooden houses. Our ridge ventilators are made of metal, and therefore are highly fireproof. In addition to tests by third-party institutions, we conduct severe watertight tests, smoke exhaust tests, etc., at 30 m/s wind velocity and 4 L/min with a large blower as is used in the Japan Testing Center for Construction Materials, etc. We give the highest importance to quality in manufacturing and providing products.
