01C / Intumescent Fireproofing

Thin-film steel protection designed from section data—not guesswork.

Intumescent coating application with project-approved design thickness, compatible primers, controlled conditions and DFT reporting.

Direct route

A controlled path from requirement to delivery.

Intumescent coatings expand under heat to form an insulating char. They are often selected where appearance, lower weight or a thinner build-up matters.

The required dry-film thickness varies by member geometry, fire-resistance period, steel temperature criterion and tested manufacturer data. Vortexen does not quote a universal thickness.

Commercial and technical guardrails

What this route refuses to hide.

Fast progress is valuable only when assumptions, responsibility and limitations remain visible to the buyer and delivery team.

01No generic DFT assumption
02No application over unknown primer
03No accelerated recoating outside limits
04No unrecorded site repair

Frequently asked

Answers before the first meeting.

01Is intumescent always thinner than cementitious fireproofing?+

It is commonly a thinner-build solution, but suitability, installed cost, environment, finish and required performance must be compared project by project.

02What does DFT mean?+

Dry-film thickness, a critical inspection measure used to verify that the applied coating meets the approved design requirement.

03Can it be applied outdoors?+

Only when the selected system, primer, topcoat and exposure classification support the environment and project requirements.

Bring the actual requirement, evidence and deadline.
