Cable, pipe and mixed penetration seals for walls and ceilings. Fire- and smoke-tight closures using all common systems — soft seal, mortar, cushion, modular. Compliant installation, documentation and labelling, in new build and existing stock.
A penetration seal is the fire- and smoke-tight closure of a service penetration through a fire wall or ceiling. Its task: keep fire and smoke in the affected fire compartment. The fire resistance of the seal must match that of the surrounding wall — an F90 wall demands an S90 or R90 seal. Classified in accordance with the applicable proofs of usability (national: S30/S60/S90/S120 for cable, R for pipe) or applicable proof of usability (European: EI). Penetration seals are a mandatory element of every fire protection concept and are governed by the model line-installation directive (MLAR) and, in NRW, by the LAR NRW.
Which variant fits depends on the installation context, the existing building and the fire-protection concept — we advise per project.
Cost-efficient solution for the most common installation contexts — tested systems from established manufacturers.
For non-standard sizes, installation contexts or higher requirements driven by the fire-protection concept or expert reports.
Recertification of existing components or phased replacement — coordinated around live operations.
All prices excl. VAT. Maintenance contracts are quoted on a per-unit basis.
We cover every typical building type — from residential to industrial complexes with hundreds of components per site.
Apartment buildings, stairwells, transitions to boiler rooms and underground garages — usually with smoke-protection properties.
Separation of production, storage and administration plus protection of mechanically loaded plant.
Schools, hospitals and administrative buildings under NRW special-buildings regulations — often combined with hold-open systems.
S30 / S60 / S90 / S120 for cable seals, R-classes for pipe seals — still relevant for existing stock.
Unified test conditions for the fire resistance of penetration seals across the EU.
Test result expressed as EI with minute rating — e.g. EI 90 for a 90-minute seal.
Federal requirement for the fire protection requirements of line installations.
Specifies MLAR for North Rhine-Westphalia (NRW) — binding in NRW.
Every system has an approval — installation must follow the manufacturer's instructions strictly, otherwise the approval is invalid.
We plan, supply and install — manufacturer-independent and with complete documentation.
Aachen to Bielefeld, Lower Rhine to Sauerland — survey usually within five working days.
No subcontractors. Warranty work and maintenance always trace back to the same people.
We schedule appointments proactively. Inspection record for the fire authority comes with every visit.
Including planning, material, installation and documentation — coordinated with electricians and other trades.
Compliant retrofit of open or defective penetrations — including during live operations.
Adding cables or pipes through existing seals — only with approved systems.
Complete defects lists from fire inspections or expert reports in one engagement.
Declaration of conformity, photo record, as-built plan, seal numbering — digital and audit-proof.
Optional: maintenance contract with annual inspection of all seals.
Pillar covering wall, ceiling and retrofit.
For concrete, masonry and drywall.
With protection against the chimney effect.
Process complete defects lists in one engagement.
Complementary for cable trays and steel structures.
Periodic inspection of all fire protection installations.
