The UK leader in Stud Welding and Refractory products
Fiberfrax® Refractory Coatings, Cements and Mastics are a range of high-temperature insulation and repair materials engineered for sealing, surface protection, refractory maintenance and thermal management applications. Manufactured using Fiberfrax ceramic fibres combined with specialist high-temperature binders, these products provide durable, insulating solutions for furnace linings, expansion joints, thermal processing equipment and molten metal handling systems.
Designed for easy application and long-term performance, the range includes mouldable mastics for sealing and repairs, high-temperature refractory mastics for demanding thermal environments and protective coating cements that provide erosion, abrasion and chemical attack resistance. Once cured, these materials form strong insulating structures capable of withstanding severe industrial operating conditions.
Widely specified throughout furnace construction, metals processing, petrochemical production and thermal processing industries, Fiberfrax refractory products provide versatile solutions for installation, maintenance and life extension of high-temperature equipment.
Fiberfrax products combine thermal insulation performance with excellent adhesion, durability and ease of application.
