As the powerhouse of Japan's manufacturing economy, the Chukyo Industrial Zone—spanning Nagoya, Toyota City, Yokkaichi, and Kariya—operates under stringent building regulations, zero-tolerance fire risk frameworks, and rigorous environmental targets. General contractors, structural engineering consultants, and industrial facility owners throughout Aichi Prefecture increasingly reject combustible polymer-foam cores in favor of high-density mineral wool sandwich panels. Our fully continuous lamination facility delivers ASTM E119, EN 13501-1 Class A1 non-combustible stone wool architectural panels engineered specifically for high-bay manufacturing facilities, automated storage and retrieval systems (AS/RS), battery cleanrooms, and coastal marine logistics zones surrounding the Port of Nagoya.
Pure basalt stone wool core delivering up to 4-hour structural fire endurance without hazardous smoke emission or flaming droplets.
Continuous high-speed double-caterpillar production ensuring rigid fiber alignment, micrometer tolerance, and rapid project lead times.
Guarantees sustained energy conservation under humid Nagoya summers and dry sub-zero winter drafts without thermal degradation.
Fabricated from premium natural volcanic basalt rock spun into dense hydrophobic mineral fibers, our rockwool panel series satisfies Japanese Building Standard Law requirements for certified non-combustibility while offering outstanding airborne sound attenuation and thermal barrier stability.
Navigating Japanese Building Standards Act (建築基準法) Article 2 and municipal fire bureau requirements in Aichi Prefecture necessitates a meticulous evaluation of core flammability, thermal performance, and long-term acoustic barrier properties.

From heavy-stamping automotive supply chains in Toyota and Kariya to coastal maritime warehousing across the Port of Nagoya, our mineral wool systems solve project-specific structural, acoustic, and environmental hurdles.
Facilities across Toyota City and Komaki house robotic body-welding lines, high-tonnage stamping presses, and CNC machinery. Our high-density mineral wool wall systems dampen heavy acoustic reverberation while establishing MLIT-mandated 2-hour non-combustible internal partitions between robotic lines and warehouse reserves.
Acoustic & Fire SegregationThe Port of Nagoya handles vital imports/exports of lithium-ion battery modules and industrial chemicals requiring Class 1 to 4 hazardous material certification under Japanese Fire Service Law. Our Class A1 stone wool panels prevent fire transmission, shielded by 25-micron PVDF resin coatings resisting saline marine salt spray.
Hazardous Materials & C5 MarineSupplying aerospace manufacturing clusters in Minato-ku and Gifu, our cleanroom panels feature micro-ribbed or ultra-smooth steel skins treated with antibacterial coatings. Seamless tongue-and-groove joins eliminate dust retention, maintain strict positive pressure, and eliminate fiber shedding through specialized edge-encapsulation.
Cleanroom ISO Class 6-8With Nankai Trough earthquake preparedness front of mind across central Japan, legacy industrial warehouses replace fragile asbestos cement or uninsulated corrugated metal with lightweight, ductile mineral wool sandwich systems mounted on engineered slotted seismic sub-framing brackets to absorb inter-story drift.
Seismic Ductility & RetrofitCombining world-class continuous production technology with customized export logistics directly serving the Port of Nagoya, our manufacturing plant provides uncompromised batch traceability and certified structural performance.
Our automated line slices high-density stone wool slabs and turns the fibers 90 degrees perpendicular to the steel skin, dramatically elevating compressive strength to ≥ 140 kPa and delivering high peel adhesion.
Eliminates capillary moisture infiltration by encapsulating rockwool core edges with closed-cell polyurethane foam along longitudinal joints, enhancing tongue-and-groove structural engagement and thermal isolation.
Every export bundle undergoes factory laser-guided thickness verification, adhesive peel strength testing, density measurement, and dimensional inspection accompanied by certified mill test reports (MTR).
Packed in fumigated export crates with UV-resistant shrink wrap and steel corner guards to survive trans-Pacific maritime humidity, arriving ready for offloading at Nagoya Port (Meiko) berths.
