■Ensuring the Continuity of Fireproof Coating The fireproof performance of our conventional products (made of aluminum) is approximately 28 minutes (based on our test values), so it is conceivable that continuity of fireproof coating cannot be ensured in quasi-fireproof structures or reinforced ceilings. By using fireproof ceiling inspection openings, continuity of fireproof coating can be secured. ■Simplification of Construction To ensure the continuity of fireproof coating, there are cases where various methods are employed, such as installing a site-manufactured box-shaped fireproof coating above the ceiling inspection opening; however, these measures can become a burden on the site. This product eliminates the need for a box-shaped fireproof coating, leading to a reduction in on-site construction effort. ■Slimming Down the Visible Width for Aesthetic Appeal Compared to products that comply with 45-minute quasi-fireproof structures, the visible width has been narrowed, and the base material has been painted for a cleaner appearance. ■Consideration for Safety During Opening, Closing, and Inspections Since ceiling materials become heavier in 60-minute quasi-fireproof structures or reinforced ceilings, a fall prevention chain is standardly equipped to prevent the lid from opening too forcefully during inspections. ■Special Column Published by Mr. Noboru Yasui, Representative of Sakura Design Group, First-Class Architect Office "What are the important points regarding fireproof coating required for quasi-fireproof and fireproof buildings?" ↓Click the related link↓

The Joto Kiso Packing Method involves laying Kiso packing between the foundation and the base at regular intervals, utilizing these intervals as ventilation openings. This method achieves full perimeter ventilation under the floor, with ventilation performance being 1.5 to 2 times better than conventional methods. It efficiently expels moisture from every corner, contributing to the creation of an ideal dry underfloor environment. Additionally, by sandwiching Kiso packing between the base and the foundation, it prevents the base from absorbing moisture from the concrete, maintaining the dryness of the base and making it less susceptible to decay fungi and termites. The material of Kiso packing is a unique composite (Joto composite material) developed by Joto Tech, combining the flexibility of resin with the strength of stone, making it resistant to aging and exhibiting excellent durability. We offer a wide range of options to accommodate various construction methods, including traditional methods and 2x4 construction.
