Achieve the required class
We select systems that match the required class (F30–F90) and the actual installation scenario.

F30–F90 describes fire resistance durations. In real projects, system choice, installation conditions and proper records decide whether fire stopping is accepted in Aachen and the surrounding area.
Typical goals (Aachen)
We select systems that match the required class (F30–F90) and the actual installation scenario.
Substrate, opening size, loading and manufacturer specifications define what is permissible.
Depending on the system, controlling smoke and fire spread through penetrations is part of the scope.
Consistent labeling, photo documentation and installation/handover records—clear for site teams and audits.

F30–F90 fire stopping depends on construction build-up, opening size and service loading—system selection and installation details matter.
Whenever cables, trays or pipes penetrate fire-compartment walls and floors, F-classes become relevant—both in new builds and retrofits.
We deliver system-compliant solutions in Aachen and nearby towns (e.g., Würselen, Herzogenrath, Alsdorf, Eschweiler, Stolberg), including labeling and documentation.
We review the current penetrations and propose an approved retrofit concept that fits the real on-site conditions.
Coordination with MEP, electrical and drywall reduces rework and supports smooth acceptance.
Not every penetration is the same. These scenarios often decide system choice, effort and long-term traceability.
Penetrations through walls/floors must meet the required class—depending on construction and usage.
Many lines in tight spaces require clear system boundaries so future additions stay manageable.
Beyond the class, maintainability and expandability often matter most in technical areas.
Documentation is often requested later. We record work so you don’t have to search months after.
We follow manufacturer specifications and adapt execution to substrate, loading and installation conditions—clean, traceable, acceptance-ready.
System selection aligned with construction, opening size and loading—no improvisation.
Structured execution so future modifications don’t become a problem area.
We verify labeling and system conformity before acceptance—so it works on the day.
F30–F90 is not one-size-fits-all. Cable/pipe type, loading, substrate and conditions define what is approved.
A clear process—so requirements are met and documentation holds up later.
Clarify requirements
Class, construction, penetrations and schedule—we align the basics quickly and precisely.
Define the system
Choose an approved solution for the scenario—including coordination with involved trades.
Install & label
Clean execution, consistent labeling and tidy handover for long-term traceability.
Document & hand over
Photo evidence and records in a structure that works on site and in operation.

Built for real sites
We focus on clean edges, system-compliant installation and clear labeling—so acceptance is straightforward and documentation stays usable.
Our focus
Compliant. Traceable. Acceptance-ready.
With fire stopping, execution matters—but so does traceability for later inspections, audits or refurbishments.

Depending on project scope—in a structure teams actually use.
Evidence prepared so it remains understandable months or years later.
