Promat: how a passive fire-protection campaign hit +272% over target and 141x ROI

Where Promat's category sits

Passive fire protection for structural steel buildings is one of the least-glamorous B2B categories you can market into. The product is a coating applied to steel structural members that protects them from collapse during fires. The buying audience is small: architects who specify it, fire consultants who recommend it, installers who apply it. The decisions are slow, evidence-driven, and regulated. The category gets no consumer attention and very little broader business-press coverage.

In 2023-2024, the UK Building Safety Act created a regulatory window where the architect and fire-consultant audience was paying more attention than usual. The Grenfell Tower fire (2017) and its regulatory aftermath had elevated fire-protection compliance from a background discipline to a frontline professional concern. Promat needed to convert that elevated attention into specification packs — the in-category equivalent of qualified sales leads.

The campaign

Promat's campaign was built around three structural choices that made it different from typical B2B marketing in adjacent industrial categories:

• Hyper-targeted audience. The campaign targeted three specific professional audiences (architects/specifiers, fire consultants, installers), each with different messages, channels, and conversion paths. No attempt to reach “the broader construction industry” or general business audiences.
• Tied to UK regulatory clauses. Messaging was specifically anchored to clauses of the UK Building Safety Act, which made the content immediately relevant to professionals who were trying to comply with the new requirements.
• Spec packs as the conversion asset. The primary lead-magnet was a downloadable spec pack with technical decision-support content. Spec packs are the actual document architects and consultants use when specifying products — the campaign delivered the tool the audience already needed, in branded form.
• Pipeline KPI, not awareness KPI. The original target was 50 spec packs — a measurable pipeline outcome, not a broader awareness metric. The clarity of the conversion target shaped the entire campaign design.

What grew, and what came with it

The campaign delivered 186 spec packs against a 50-pack target — a +272% overperformance. Reported ROI on the campaign budget was 141x. The spec-pack conversions translated into project-level engagements with architects and fire consultants, which feed into the long sales cycle typical of specialty building-products categories.

The campaign also helped reframe how Promat's parent company (Etex Group) thinks about B2B marketing in specialty industrial categories. The structural lesson — precision targeting + regulatory-clause messaging + practical decision-support content — has been applied to other Etex categories with comparable buyer-population characteristics.

What other specialty B2B brands could copy

The Promat approach transfers to other specialty B2B categories under specific conditions:

• Small, well-defined buyer population. Specialty B2B works when you know exactly who the buyers are and can reach them precisely. Categories where the buyer is fuzzy don't produce the same precision economics.
• Regulatory or compliance anchor. Tying messaging to specific regulatory requirements (like the UK Building Safety Act) gives the campaign a forced-attention window that broader marketing can't produce. Categories without an active regulatory anchor have to find other timing levers.
• Practical decision-support content. Spec packs work because they're the actual tool the audience uses. Industries where the buyer uses comparable tools (standards documents, design checklists, compliance worksheets) can apply the same model.
• Pipeline-KPI clarity. Setting a measurable conversion target shapes the campaign design. Campaigns aimed at awareness or engagement without a pipeline target tend to produce neither.

How RGM thinks about specialty-B2B campaigns

When clients in specialty B2B categories ask about marketing approaches, the Promat case is the example we point to first. The temptation in any B2B category is to chase reach — reach more architects, reach more consultants, reach more buyers. In specialty categories, that’s usually the wrong move. The right move is to identify the small, specific audience that actually makes the decision, target them with precision and timing, and deliver conversion assets they need.

The harder lesson is about ROI math. The 141x ROI figure reflects a small absolute budget and a conservative initial target. The directional truth (precision targeting outperforms reach in specialty B2B) is real; the specific multiplier shouldn’t be expected to replicate at larger budgets. As you scale spend in specialty B2B, you usually exhaust the precision audience and start paying for the reach-based audience that converts at much lower rates. The ROI compresses with scale. We tell clients to plan for that compression rather than assuming the early-campaign multipliers will hold as the program grows.
