Penetration Sealing 

Expert Installation for Compliance and Fire Safety Assurance.

Architectural blueprints with integrated fire safety systems

At Flamesafe Solutions Ltd, we specialise in restoring and maintaining the integrity offire compartments by professionally sealing service penetrations that breach fire-rated walls and floors. These are common access points for building services such as cables, pipes, and ductwork—each posing a serious risk to the performance of passive fire protection systems if left unsealed or incorrectly treated.

Our highly trained and experienced team carries out all penetration sealing works in strict accordance with current fire safety legislation and manufacturer guidelines. All operatives are fully certified and continually trained in the correct application offire-stopping systems. From initial site assessments to installation and reporting, our team ensures a compliant, traceable, and quality-assured process from start to finish.

We use only third-party certified fire-stopping products—including coated fire batts, intumescent sealants, collars, and wraps—to ensure compatibility with the surrounding structure and services.

Why It Matters


Unsealed or inadequately sealed service penetrations are a key cause of fire and smoke spread within buildings. Effective penetration sealing helps:

  • Maintain fire compartmentation
  • Protect life safety routes
  • Support regulatory compliance (e.g. Approved Document B, BS 476, and BS EN 1366)
  • Reduce potential property damage

Supporting Compliance & Safety

Our penetration sealing service covers:

We work closely with building owners, fire risk assessors, contractors, and facilities managers to ensure that fire-stoppingmeasures are not only installed correctly but are also suitable for the specific environment and building use.

All our work is carried out under our robust internal quality systems and can be included as part of a widercompartmentation strategy or passive fire protection inspection.
