Passive Fire Protection
We design and install passive fire protection systems that compartmentalise buildings to slow fire and smoke spread. Our solutions meet BS and EN standards, ensuring compliance with current building regulations. Systems include cavity barriers, fire curtains, and penetration seals tailored to new builds and retrofit projects.
Penetration Sealing
Our penetration sealing systems close gaps around pipes, cables, and ducts in fire-rated structures. Using third-party tested materials, we restore fire integrity in compliance with BS 476 and EN 1366 standards. Each installation includes documentation and on-site labelling for traceability during inspections.
Cavity Barriers
We supply and install cavity barriers to prevent hidden fire spread through concealed spaces. Our systems meet Approved Document B requirements, with fixed-position fire curtains providing compartmentation in open-plan areas while maintaining architectural design integrity.
Compound Seals
For large openings with grouped services, we create durable compound seals using fire-rated mortar. These load-bearing systems provide long-term protection in plant rooms and service zones, with full documentation to support compliance handover requirements.
Acoustic Sealing
Our acoustic sealing solutions meet Part E building regulations by limiting sound transfer between spaces. We install sound-rated barriers and batt systems in residential, commercial, and healthcare buildings, combining fire protection with noise reduction for occupant comfort.
