Fire-rated wall assemblies for UAE Civil Defence compliance

TL;DR: fire resistance is a property of a complete, tested wall assembly — not of a block on its own — so the honest path to a Civil Defence-compliant separation, shaft or party wall is to specify a sound Tiger Stone build-up and then verify it with a project-specific lab report. A 200 mm hollow or insulated Tiger Stone wall, plastered both sides with 12 mm cement plaster and built with full mortar joints, is the assembly we typically recommend for the separation, shaft and party-wall conditions Civil Defence calls out in residential and commercial buildings.

Fire resistance under the BS 476-22 methodology is measured against three criteria — integrity, insulation and (for loadbearing walls) stability — for a specific assembly that was actually tested: a defined block, thickness, mortar, plaster and any penetrations. Because the rating belongs to the tested build-up rather than to the block, Tiger Stone does not publish a generic lot fire-test report and we will not quote an hour figure for your wall sight-unseen. What we can do is help you specify the assembly and, if your project needs it, arrange an independent UAE-accredited lab test on the lot supplied at quote stage as a paid sample test. See /certifications for the standards we manufacture against.

To keep your submission clean: choose wall thickness for the separation duty your consultant has scheduled (the 200 mm series for the more demanding separations, lighter walls where a lower duty is allowed), keep mortar joints full at 10 mm, plaster both faces at 12 mm, and sleeve or fire-stop any through-pipe penetrations rather than coring the wall raw. Send us your wall build-up and the rating your authority requires, and we will confirm the recommended Tiger Stone series and set up the verification test you can submit.
