Isofrax® Blankets are advanced low biopersistent insulation blankets engineered to provide outstanding thermal stability, low thermal conductivity and reliable high-temperature performance in demanding industrial environments. Manufactured using proprietary silica-magnesia fibre technology, Isofrax Blankets offer a unique combination of insulation efficiency, durability and dimensional stability.
Designed to withstand severe thermal cycling and elevated operating temperatures, Isofrax Blankets maintain their performance where conventional insulation materials may experience increased shrinkage or degradation. Their lightweight, flexible construction simplifies installation while helping improve energy efficiency and reduce heat loss across a wide range of thermal processing applications.
Available in Isofrax 1260C and Isofrax 1400 grades, the range provides dependable insulation solutions for applications requiring enhanced thermal stability, corrosion resistance and long-term reliability.
Isofrax Blankets combine advanced fibre technology with excellent thermal performance, providing a versatile solution for high-temperature insulation and thermal management systems.
