Enables fire compartment penetration of soundproof drainage pipes! Eliminates dual management of fire-resistant and non-fire-resistant! Certified by the Minister of Land, Infrastructure, Transport and Tourism, evaluated by the Japan Fire Equipment Safety Center.
The "Hitomaru Twin Pat" is a fireproof partition penetration material that has the function of expanding and foaming during a fire to seal penetration holes. By using "Hitomaru" in conjunction with piping, it enables fireproof partition penetration for "Otofuji." The "Hitomaru" seals the penetration holes and stops the spread of fire. With the "Hitomaru Twin Pat," you can be freed from the dual management of fire-resistant and non-fire-resistant (single-family) soundproof drainage pipes, eliminating the need for double inventory and waiting for delivery. Furthermore, when used in conjunction with "Otofuji," the effectiveness is further enhanced.

basic information
【Features】 ○ Eliminate double management! → With the "Hitomaru Twin Pad," you can be freed from the double management of fire-resistant and non-fire-resistant (for detached houses) soundproof drainage pipes, eliminating double inventory and waiting for delivery. ○ Excellent soundproofing performance → The sound-absorbing material of "Otofuji" uses urethane foam, which is highly effective against drainage noise. → The combination piping with "Hitomaru" makes it possible for the urethane foam material to penetrate fire compartments for the first time, achieving more stable soundproofing effects. ○ Lightweight and easy to handle! → Due to differences in material composition, "Otofuji" is approximately 15% lighter than conventional fire-resistant soundproof drainage pipes, contributing to improved work efficiency. → The "Hitomaru" twin pad structure allows for installation after piping. → Since it uses adhesive bonding, no tools are required.
