Two wool routes, two application lists
Rock wool and glass wool are the two wool routes in this catalogue, and each carries its own application list on the company homepage. Rock wool is listed for building, industrial, fire-protection and acoustic insulation assemblies. Glass wool is listed for building envelopes, heating and cooling systems, mechanical systems and acoustic applications. The overlap is real: both routes appear in building work and in acoustic work. The difference sits in the remaining lines, where rock wool carries industrial and fire-protection assemblies and glass wool carries heating and cooling and mechanical systems.
Reading the two lists side by side is the fastest way to see whether the choice is already narrow. A buyer whose job is an industrial assembly or a fire-protection assembly starts from the rock wool list. A buyer whose job is a heating and cooling system or a mechanical system starts from the glass wool list. A buyer whose job is a building envelope or an acoustic assembly has both lists open and needs a second question, usually about form, before the choice narrows. The application lists do not settle a job on their own, and this guide treats them as starting points rather than answers.
Forms that overlap, forms that differ
The two routes also share most of their product forms, which is why form alone rarely separates them. Rock wool is listed in boards, blankets, pipe sections and batts. Glass wool is listed in batts, blankets, boards and pipe sections. The same four form names appear in both routes, in a different order, and the catalogue describes each form group on its own form page. A board enquiry, a blanket enquiry, a pipe section enquiry and a batt enquiry each need different handling on site, whatever the route, and the form pages set out what a buyer should state so the form can be matched to the job.
Because the form names match, a buyer who names only a form has not yet chosen a route, and a buyer who names only a route has not yet chosen a form. The enquiry checks in this catalogue therefore ask for route and form together, and the guide pages return to that pairing whenever a selection question is discussed. A message that states both gives the supplier something concrete to answer, while a message that states one leaves the first reply to be a question rather than a quotation of terms.
Building envelopes and interior assemblies
Building work is the ground where the two routes meet most directly. Glass wool is listed for building envelopes, which covers the outer layers of a building where insulation sits inside a larger construction of walls, roofs and interior assemblies. Rock wool is listed for building assemblies more broadly, which covers the same kind of construction work with an additional industrial and fire-protection emphasis. A buyer describing a wall, a roof or an interior partition should state the construction type, the layer the insulation sits in, and whether the assembly is part of a larger system, because those details shape which form fits.
Interior assemblies raise a second set of questions that belong in the enquiry rather than in a route name. Partitions, ceilings and lined walls each need a form that fits the space available and the way the assembly is built up. Blankets and batts suit flexible coverage over larger surfaces and framed assemblies, while boards suit flat assemblies where a rigid layer is wanted. Stating the assembly type, the available depth and the surface the insulation fixes to turns a general building question into a specific one that the supplier can answer against the listed forms.
Heating, cooling and mechanical systems
Heating and cooling work is where the glass wool list is strongest. Glass wool is listed for heating and cooling systems and for mechanical systems, which covers ducts, pipes and equipment where insulation follows the shape of the system it serves. A buyer with a duct run, a pipe run or a piece of equipment should describe the system in those terms: what carries heat or cold, what shape it takes, and where the insulation must bend, wrap or sit flat. Pipe sections suit pipework, while blankets and boards suit flatter or larger surfaces in the same system.
Rock wool also appears in industrial systems, and an industrial heating or cooling job may sit on either list depending on how the buyer describes it. The useful question is not which route name sounds closer but which system the insulation serves and what the surrounding conditions are. Industrial pipework, plant rooms and equipment rooms each bring their own access, temperature and handling questions, and the enquiry should state the system, the medium it carries and the parts that need covering, so the reply can address the actual job rather than a route label.
Acoustic work in both routes
Acoustic applications appear in both routes, and acoustic work is a case where the room or partition matters more than the route name. Sound behaviour belongs to rooms and partitions as assemblies, and the insulation inside them is one part of a larger build-up. A buyer with an acoustic question should describe the space: what kind of room or partition it is, what sits on either side of it, and what the insulation layer is expected to sit between. That description lets the supplier respond to the assembly rather than to a single material word.
Form matters in acoustic work in the same way it matters elsewhere. Blankets suit flexible coverage over larger surfaces, batts suit framed assemblies, and boards suit flat assemblies where a rigid layer is wanted. The catalogue pages for acoustic assemblies set out those form groupings, and a buyer who states the assembly type together with the preferred form gives the enquiry a clear shape. Where the acoustic requirement is set by a project specification, the enquiry should quote that specification and ask what documents apply to the items named, since documents are confirmed per order.
Fire-protection assemblies as an application line
Fire-protection assemblies appear on the rock wool application list, and this guide treats that line the way the catalogue treats it: as an application category, not as a rating or a promise for any particular order. An assembly is a built-up construction of several parts, and its behaviour depends on the whole build-up rather than on one layer inside it. A buyer with a fire-protection question should describe the assembly as a whole, including the structure it protects, the layers around the insulation, and any project specification that governs the assembly.
Documents for such work follow the same rule as documents elsewhere in this catalogue: certificates are available upon request, and the enquiry should name the items and ask what documents apply to them. No rating, standard name or test result is stated for any particular item in this guide, because none is published here for a specific order. The enquiry is the place where the assembly description and the document question meet, and a complete assembly description is what makes a useful document answer possible.
Narrowing the choice by form first
A practical way to narrow the choice is to decide the form before deciding the route. Start with the surface or system: a flat surface points to boards, a pipe points to pipe sections, a framed assembly points to batts, and a larger flexible surface points to blankets. Once the form is fixed, the remaining question is which route list contains both the form and the application, and in building and acoustic work that question may still leave both routes open. At that point the deciding details are usually the system, the setting and the project specification, all of which belong in the enquiry.
This form-first reading also prevents a common enquiry error, which is to name a route without naming a form. A pipe section enquiry and a board enquiry may share a route name and still need entirely different handling, cutting and fixing on site. The catalogue form pages describe each form group in plain terms, and the enquiry checks ask for route and form together for exactly that reason. A buyer who states both from the start gives the supplier something concrete to answer, and the reply can then address quantities, timing and terms for the items named.
Enquiry questions for the two wool routes
A complete enquiry for either wool route states the route, the form, the application and the setting. It names the assembly or system, the surface or shape the insulation must fit, and any project specification that governs the work. It also states the quantities involved in the terms the buyer can measure, such as the area, the length of pipework or the number of assemblies, so the supplier can respond to a defined scope rather than to a general interest.
The enquiry should also ask for the commercial and document points to be confirmed together: the quantity, the timing and the terms for the items named, and the documents that apply to them. Certificates are available upon request, and naming the items in the enquiry is what makes a document answer possible. The companion guides in this catalogue cover pipe selection, heating and cooling work and fire-protection work in more depth, and the route pages for rock wool and glass wool carry the same topics in catalogue form for buyers who want the shorter version first.
