Industrial insulation failures cost plants $500k/hour in downtime. Our 50mm-100mm thick insulation boards use aerogel-enhanced foam cores to maintain R-10 values at cryogenic temperatures. The 2-inch rigid foam board insulation variant withstands 25psi mechanical loads in refinery pipe supports. For sound control, the same acoustic insulation panels reduce turbine noise by 40dB(A) in power stations. All industrial insulation sheets undergo third-party testing for chemical/UV resistance - critical for offshore oil rigs and pharmaceutical cleanrooms. With ISO9001-certified traceability, we help EPC firms comply with ASHRAE 90.1 and OSHA standards.
