Systems fail at interfaces
Fire-rated partitions are often drawn as a line on a plan, but certifiers see screws, batts, sealant, and doors in the real world. Carval Interior Lining installs rated systems exactly as tested, including the boring details: correct stud centres, specified board types, and penetration seals that match the test report—not a generic pink foam.
We maintain a digital register of every rated wall on a project: tag number, level, system reference, and photo evidence before closing. That register travels to handover so building managers know which walls cannot be casually penetrated when tenants request extra power points.
Coordination with other trades
Electricians and mechanical contractors must cut and seal in sequence. Our site supervisors run joint walk-throughs at lock-up stage to catch unsealed penetrations while access is still available. Retrofit sealing after paint is slower, uglier, and sometimes non-compliant.
Our viewpoint
If your project mixes rated and non-rated partitions, segregate packages in the bill of quantities and name the responsible installer. Ambiguity invites substitution. Rated works are not the place for cheapest-price tendering without a technical submission.
Rated walls fail at penetrations and interfaces, not on the plan line.
