Keep compartments intact
Penetrations are a common weak spot. Proper seals help prevent fire, smoke and hot gases from spreading to adjacent compartments.

What are pipe penetration seals in Aachen?
A pipe penetration seal is a fire protection measure for penetrations. It restores the required fire resistance of a wall or floor in the penetration area – commonly required in industrial and commercial buildings in Aachen.
Depending on pipe material (e.g., steel/copper vs. plastics), insulation, wall/floor type and the required fire rating, different tested systems are used.
Key principle: system-based execution, not improvisation. The selected system must match the actual installation conditions (Aachen, Würselen, Herzogenrath and nearby).

Plastic pipes are critical
Combustible pipes may soften or melt under fire exposure. Intumescent components are designed to close the opening when the pipe fails.
Documentation reduces risk
Labeling and evidence (photos, system documentation) are often essential for handover, inspections and facility operation.
SYSTEM OVERVIEW
Common systems & types
The right solution depends on more than the pipe itself: substrate, opening size, insulation, position and combinations also matter. For projects in Aachen and surrounding areas, we select and execute system-compliant solutions based on the real installation conditions.
System principle (example)
Visual reference for typical components and placement.
Retrofit situations (example)
Useful when space is limited or for existing penetrations.
Fire collar (intumescent)
Often used for combustible pipes. The material expands in a fire and helps close the opening as the pipe yields.
- For plastic & composite pipes (system-dependent)
- Walls and floors
- With/without insulation depending on approvals
Wrap / bandage systems
Flexible for tight spaces or retrofits. Installed around the pipe with defined overlaps and fixing details.
- Space-saving in shafts
- Good for retrofits
- Strict layer/overlap rules
Mortar / mineral-fiber based seals
Used to close openings with compatible materials, sometimes combined with additional components depending on the system.
- Defined opening sizes
- Often for solid walls/floors
- Only per system rules
Mixed / multiple penetrations
Multiple services in one area require careful planning and compliance with the tested configuration.
- More services = more rules
- Spacing & edge conditions matter
- Plan before you install
Pipe types & field conditions
To choose the correct system, we clarify these points first:
Typical field conditions
Construction type, insulation length, pipe material and spacing decide which tested system is allowed.
Metal pipes (e.g., steel, copper)
Metal is non-combustible but conducts heat well. Systems must consider heat transfer, gaps and insulation conditions.
Plastic & composite pipes
Melting/softening behavior is the key. Intumescent components aim to close the opening as the pipe fails under fire exposure.
Insulation
Insulation type and thickness can change the permitted system and installation details significantly.
Construction type
Solid concrete/masonry vs drywall assemblies: the build-up defines what is permitted and how it must be installed.
Practical note
Most issues are not caused by the product itself, but by boundary conditions: wrong opening size, missing clearances, unclear insulation or mixed penetrations without verified evidence.
Planning checklist
A practical checklist to keep selection, installation and documentation aligned:
- 01
Identify construction: wall/floor, solid/drywall, thickness/build-up
- 02
Capture pipe data: material, outer diameter, type (composite etc.)
- 03
Confirm insulation: type, thickness, length, continuity
- 04
Measure opening: size, edge distances, service density
- 05
Confirm required rating: project specs, compartmentation, EI/F class
- 06
Select the tested system and define installation details
- 07
Plan labeling & photo documentation from day one
Labeling & documentation
In Aachen and surrounding areas, it’s not only about installation quality but also proof. Clear labeling and structured documentation help during acceptance and later operation.
QUALITY
Clear proof for handover & audits
Labels, photos and system documentation make the installation traceable — a strong signal of quality.
Permanent label per penetration seal
Photo documentation before/after installation
Store system documentation/approvals with the project records
Document deviations and clarify — no improvisation
Our standard
System selection + clean installation + traceable documentation. This keeps the project verifiable — in new builds and existing facilities.
