Steel may be strong, but in a fire it loses integrity fast. Our fire-rated encasement systems are designed to delay heat transfer, maintain load-bearing capacity, and help your entire building stay stable long enough for evacuation and emergency response.

What We Do

  •  Install fire-rated board encasement systems

  •  Protect exposed steel columns, beams & trusses

  • Ensure compliance with Part B & manufacturer specifications

  • Create clean, seamless finishes ready for follow-on trades

  • Provide full reporting & certification

Why It Matters

Unprotected steel can buckle within minutes during a fire. Proper encasement:

  • Increases resistance times (typically 30–120 mins)

  • Supports compartmentation

  • Reduces legal and insurance risk

  • Keeps your project compliant and future-proof

Our Process

  1. Inspection & measurement of steelwork

  2. Specification of the correct board system (Promat, Rockwool, Siniat etc.)

  3. Professional installation to tested detail

  4. Quality checks and photographic evidence

  5. Certification on completion
