Buildings can be designed with the best fire protection strategy in mind, but later changes may compromise that safety.

Service lines installed after fire rated floors and walls are already in place can create gaps and voids that seriously increase the risk of fire spreading, despite the strong initial design.

Void fillers and fire sealants provide solutions to close any penetrations – restoring the building to its original performance levels.  

Learn how ROCKWOOL products can help ensure all fire-stopping points in your construction are secure.

Why do we need void fillers and fire sealants?

In both original construction and renovation projects, ensuring the best fire safety levels throughout the entirety of a building’s lifetime is essential1.

Ongoing work, improvements and changes can compromise existing fire materials and plans – with service line penetration or accidental damage on-site just two examples.

Before a site can be declared fit for purpose, every single fire stopping point needs to be checked to ensure its integrity is intact. Void fillers and fireproof sealants can be used to secure any gaps that have appeared, and ensure maximum safety.

Calculator and savings

Fire resistant sealant products are designed to improve building safety. Their application can be the difference between a controllable fire and one that causes serious, costly damage – and puts lives at risk.

The amount of sealant, coatings or penetration fillers required will depend on the size of your building and areas that may be at risk of compromise. Contact our experts for assistance with your requirements.
