Blanket, board, module or pyro block — what each form is for, where the 1260 °C rating genuinely applies, and how to handle the material safely.
The forms, and what each is for
Blanket is the general-purpose lining and back-up insulation. Rigid board is used where the lining must hold a shape or take light mechanical load. Rope and paper are gasketing and expansion-joint materials. Modules and pyro block are folded, pre-compressed assemblies for fast furnace lining with minimal joints.
What the temperature rating means
A 1260 °C classification is a classification temperature, not a continuous service temperature. Continuous duty is normally specified well below it, and shrinkage over time is the property that actually decides lining life. Ask for the shrinkage figure at your operating temperature, not just the class.
Handling
Ceramic fibre is a respiratory irritant, and after high-temperature service it can contain crystalline silica. Our crews work to the ISO 45001 system: correct PPE, wetting before strip-out, sealed disposal and a documented method statement for the site file.
If you would like this applied to your own plant rather than discussed in general terms, send us the details and we will put a specification in writing.

20 Aug 2026We had exactly this argument on our steam line last year. Wish we had read this before we re-did it twice.

20 Aug 2026Clear and practical. The point about specifying against maximum temperature, not running temperature, is the one people always miss.

20 Aug 2026Good read. Would like to see a follow-up on cladding detailing for coastal sites.
