Residential
Intumescent Fire-Proofing

Overview of the service

Intumescent fire-proofing protects structural steel by slowing heat transfer during a fire and helping maintain its load-bearing capacity for a specified period.

BlastOff Solutions provides intumescent fire-proofing for commercial, industrial, and residential projects where exposed steel must meet fire rating and compliance requirements. Coatings are applied in line with project specifications and fire engineering documentation.

Frequently asked questions

What is intumescent fire-proofing?

It is a fire protection coating that expands when exposed to heat, forming an insulating layer that helps protect steel during a fire.

Is fire-proofing required for residential homes?

Not always. Fire protection requirements depend on the building design, building consent documentation, fire rating requirements, and the intended use of the structure. Structural steel in some residential homes, multi-unit developments, and commercial buildings may require fire protection to comply with Building Code requirements and achieve the specified fire resistance rating.

Will the coating change the appearance of the steel?

Yes, intumescent coatings typically create a smooth painted finish over the steel. The final appearance depends on the fire rating required and the thickness of the coating system. In most cases, a decorative topcoat can be applied to achieve the desired colour and finish while maintaining the fire protection properties.

How long does the coating last?

When properly applied and maintained, intumescent fire protection systems can last for decades. The service life depends on the environment, exposure conditions, and the protective topcoat system used. Internal applications generally experience very little deterioration and can provide protection for the life of the building when maintained correctly.

Can fire-proofing be added during a renovation?

Yes. Intumescent fire protection can often be applied during renovations, refurbishments, change-of-use projects, or building upgrades. Existing steel can be assessed, prepared, and coated to achieve the required fire rating, helping bring the structure into compliance with current design or consent requirements.
