Fire Stopping for Data Centres
Protecting critical facilities through effective compartmentation
HD Construction provides specialist fire-stopping services for new-build, expansion and refurbishment projects within the data centre sector.
Our team installs fire-stopping systems designed to maintain compartmentation, protect service penetrations and preserve the specified fire performance of walls, floors and ceilings.
All work is carried out in accordance with the approved fire strategy, project specification, tested system details and relevant manufacturer requirements.
Specialist fire stopping for data centres
Data centres contain sensitive equipment, extensive cabling and complex mechanical and electrical systems. These services frequently pass through fire-rated walls, floors and ceilings, creating openings that must be correctly sealed.
Fire stopping helps restrict the passage of fire, smoke and heat through these openings. It also supports the integrity of designated fire compartments, helping protect people, equipment and essential areas of the facility.
HD Construction works closely with main contractors, fire consultants and MEP contractors to coordinate fire-stopping requirements throughout the project.
Our fire-stopping services
Our data centre fire-stopping services can include:
- Cable penetration sealing
- Cable-tray and containment penetrations
- Pipe and duct penetrations
- Electrical socket and service openings
- Linear gap seals
- Head-of-wall seals
- Perimeter seals
- Fire-rated wall interfaces
- Fire-rated floor penetrations
- Ceiling and soffit interfaces
- Fire collars and pipe wraps
- Fire-resistant compounds and mortars
- Fire-rated sealants
- Fire batts and coated-board systems
- Identification labels and installation records
- Inspection, remedial and making-good works
Every proposed system must be suitable for the specific service, substrate, opening size and required fire performance.
Protecting cable and service penetrations
Data centre projects contain a high concentration of electrical cables, containment systems, pipework, ventilation and cooling services.
Where these installations pass through a fire-rated construction, the opening can affect the intended performance of the compartment. The penetration must therefore be sealed using a suitable tested system.
Before installation, we review:
- The type and size of the penetrating service
- The wall, floor or ceiling construction
- The size and condition of the opening
- The required fire-resistance period
- Movement and maintenance requirements
- The approved fire-stopping detail
- Compatibility between specified products
If an opening cannot be covered by an approved detail, it should be referred to the appropriate designer or fire-stopping specialist before work continues.
Maintaining fire compartmentation
Fire-rated walls, floors and ceilings divide a building into compartments intended to restrict the movement of fire and smoke for a specified period.
Fire stopping is used to close joints, gaps and penetrations that could otherwise create a route between compartments.
Our work can support compartmentation around:
- Data halls
- Electrical rooms
- Battery and plant rooms
- Generator areas
- Control and monitoring rooms
- Offices and operational spaces
- Corridors and escape routes
- Risers and service shafts
The exact requirements must follow the approved project fire strategy and construction details.
Coordinated with mechanical and electrical services
Effective fire stopping depends on careful coordination with the contractors installing cables, containment, ducts, pipes and other services.
HD Construction reviews the location and arrangement of penetrations before sealing work begins. This helps ensure that openings are accessible, suitably formed and ready to receive the specified system.
Our coordinated approach helps reduce:
- Unapproved mixed-service penetrations
- Inadequate spacing between services
- Oversized or irregular openings
- Damage caused by later installations
- Repeated remedial work
- Delays during inspection and handover
Fire-stopping systems must not be altered or penetrated after completion unless the change is reviewed and correctly reinstated.
Traceable installation and quality records
Clear records support inspection, handover and future maintenance.
Subject to the project requirements, our quality-control process can include:
- Pre-installation surveys
- Opening and penetration identification
- Product and batch information
- Before-and-after photographs
- Installation dates
- Installer details
- Location references
- Fire-stopping identification labels
- Inspection and sign-off records
- Remedial-work tracking
The required documentation should be agreed before installation begins so that records are collected consistently throughout the project.
Our delivery process
- Review the requirements
We review the approved fire strategy, drawings, penetration schedules, specifications and tested system details.
- Survey the work areas
Openings and service penetrations are checked for their dimensions, condition, accessibility and compatibility with the specified system.
- Confirm the proposed solution
The fire-stopping system is matched to the service type, supporting construction and required performance. Any unsuitable or unapproved conditions are raised before installation.
- Install and identify the work
The approved products are installed in accordance with the tested detail and relevant manufacturer instructions. Completed installations are labelled where required.
- Inspect and document
The work is checked and the agreed quality records are compiled for project handover.
Quality and installation controls
Fire-stopping performance depends on correct product selection and careful installation.
Our approach focuses on:
- Following approved construction details
- Using compatible components
- Preparing openings correctly
- Applying the required material depths
- Maintaining suitable spacing around services
- Recording concealed work before it is covered
- Protecting completed installations from damage
- Reporting changes and non-standard conditions
Fire stopping should form part of the wider fire-safety design and should not be treated as an isolated finishing activity.
