Fire behaviour belongs to assemblies
Fire behaviour is a property of an assembly, not of a single layer in isolation. A wall, partition or roof assembly performs as a whole, with each layer, fixing and junction contributing to the result. Rock wool is presented for fire-protection assemblies among its applications, and that application line should be read at assembly level: the question is how the assembly as a whole is put together, not what any single board or batt can do on its own.
An enquiry with a fire element should therefore describe the assembly and the setting together: the wall or partition type, the layers involved, the fixings and junctions, and the requirement that applies to that assembly. A requirement stated without an assembly cannot be answered reliably, and an assembly stated without a requirement cannot be judged. Both facts belong in the enquiry, in that order.
Forms in fire-protection assemblies
Rock wool boards suit flat runs within fire-protection assemblies, where a firm layer is laid against a surface or within a build-up. Blankets suit areas where a flexible layer must follow a shape or cover a larger area. Batts suit framed assemblies and cavities, where pieces are fitted between members. Pipe sections suit pipework passing through assemblies, where insulation must close around a pipe and follow its run through the assembly.
Each form raises its own fixing and junction questions, and those questions should be stated in the enquiry. A board enquiry should state the surface and how the board will be held in place. A batt enquiry should state the frame or cavity it must fit. A pipe section enquiry should state the pipe sizes and the passages involved. Those facts let the discussion stay on the assembly rather than drifting into general material talk.
Questions the brief should answer
A fire-protection brief should answer: which assemblies are involved; what requirement applies to each assembly; how the assemblies are built up, layer by layer; and how junctions, passages and fixings are handled. Each of those questions should be answered for a named assembly, since a requirement that applies to one assembly may not apply to another. An enquiry that answers those questions for each assembly will receive a more direct answer than one that states a requirement without an assembly.
Document questions follow the same order: assemblies first, documents second. Certificates are available upon request. A buyer who needs a document for a fire-protection assembly should name the assembly and the requirement together, so that the answer can be tied to that assembly.
From brief to an order
Once the assemblies, the forms and the requirements are known, the remaining questions are commercial: quantity terms, timing, trade terms, payment method and documents for the items named. None of those points is stated as a catalogue fact on this site, and each should be asked for the items named in the enquiry. An enquiry that follows that order, assembly first, then form, then requirement, then commercial and document questions, will produce answers that can be checked against the order.
The general checklist collects those questions in order, and the rock wool pages give the route and form background against which the brief can be tested. Reading those pages before the enquiry will make the enquiry itself shorter and more direct, and will help the buyer judge whether the answers address the assemblies named.
