In an industry where others simply produce textiles and sleeves, Insulflex® offers high-tech solutions. From passive heat and fire protection to highly emissive surface configurations, we manage all aspects of thermal protection. We look at the radiant, convective and ambient modes of heat energy transfer and develop custom solutions to meet your needs. We were first in our industry to develop our own K value testing technology (co-efficient of resistance to thermal conductivity) and first to certify fire protection sleeves to recognized ASTM, ISO, DIN and EN standards.
