Passive firestopping for penetrations and joints
Firestopping works as a complete system at service openings, joints and transitions. Define each opening by dimension, service condition and the required fire performance before requesting packages, accessories and supporting documents from suppliers.
Start with the right material groups.
Service penetration seals
Identify each opening by service type, size and annular condition. Request the full seal assembly for the specified installation, not only the primary filling material.
Linear joint seals
Describe the movement range, substrate edges and fire rating for each joint. Ask suppliers to identify the matching sealant, backing and board components as one package.
Perimeter and transition systems
For edge-of-slab and wall-to-floor conditions, define the tested configuration. Clarify which side of the slab or wall each component is supplied for and how the system is installed.
A material price is only part of the package.
One schedule, clearly separated scopes. This is a request outline, not an installation drawing.
Included materials
List sealants, mortars, boards, wraps, collars and backing materials by area, opening count or linear length, tied to the current opening schedule.
Connections & interfaces
Identify the services passing through each opening, including insulated and uninsulated metallic or plastic pipes, cables and cable bundles.
Confirm separately
Confirm whether substrate preparation, installation, inspection and waste allowances are included within the same supply scope or managed by others.
Six details that make offers clearer.
- Exact product designation
- Name the required filler, sealant, wrap, collar or sheet product and the project-prescribed assembly or performance class for each opening type.
- Opening and service condition
- State opening width, depth, service size and material so suppliers can match the system to the specified assembly.
- Fire performance requirement
- Request the project-level performance for integrity, insulation and any smoke sealing requirement as defined by the specification.
- Accessories and field-applied parts
- Include backing, tools, fixings, intumescent wraps and sleeves if they are needed to complete the specified installation.
- Quality evidence
- Ask the supplier to attach the proposed system documentation, including tolerances and the tested or assessed opening range claimed.
- Handling and shelf life
- Request shelf-life data, storage limits and batch identification for time-sensitive sealants, mortars and preformed components.

Example quantities only; no live prices or supplier offers. Use your project schedule for final values and ask suppliers to list deviations.
Three checks before you decide.
Opening schedule matches proposal
Compare each quoted system against the opening service, size and substrate condition. Confirm the offer covers the complete specified assembly.
Accessories and installation items
Check whether backing, wraps, collars and fixings are included in the firestop package or supplied by another package.
Claimed system limits
Request the supplier to state the assessed range for each proposed system and any deviations from the project opening schedule.
Details worth clarifying early.
How should openings be grouped for enquiry?
Group by opening type, service condition and required performance rather than only by product. This helps suppliers propose the matching system and quantify pack requirements.
What should be requested for mixed-material penetrations?
For penetrations combining pipes, conduits and cables, ask for the full tested or assessed configuration and state the exact service materials and dimensions present.
