Illustrative technical application: Passive fire protection & firestopping
01 / Specialisation

Passive fire protection & firestopping

Protect the continuity of fire compartments around pipes, cables, joints and technical enclosures. We help define an executable package around the specified tested systems, coordinated openings and inspection records.

Work scope details ↓

We review the opening register, substrate, service type and specified fire compartment requirements. The package covers coordination of wall and slab penetrations, perimeter joints and technical enclosures. We organise material traceability, installation sequencing and access for inspections. Each location is recorded before closure; deviations are referred to the responsible designer and the agreed system documentation.

What helps us prepare your proposal Fire strategy, opening schedule, service types and required performance.

Illustrative technical application: Drywall, X-ray linings & specialist interiors
02 / Specialisation

Drywall, X-ray linings & specialist interiors

Bring partitions, shaft walls and technical linings together with the installations they surround. Metal framing, insulation, board layers and perimeter details are coordinated before closing. X-ray shielding follows the specialist design and acceptance requirements.

Work scope details ↓

We coordinate setting-out, tracks, studs, reinforcement, insulation, board layers and finishing interfaces against the wall schedule. Openings, door frames and services are checked before concealed work is closed. Quality records address product identification, layer continuity, joint staggering and specified acoustic or fire details. Radiation shielding requires a project-specific specialist design and acceptance; an XR profile alone does not establish shielding performance.

What helps us prepare your proposal Wall schedules, acoustic/fire requirements and shielding design where applicable.

X-ray / Radioprotection: Lead-free X-ray shielding gypsum boards may contain barium sulfate. The illustrated four-board build-up is project-specific and requires verification by the responsible radiation-protection specialist.
