Intumescent Paint
Thin film Intumescent coatings can provide a durable and attractive surface, similar to a paint finish. However, in a fire the Intumescent will expand to many times its original thickness. This provides an insulating foam-like char to protect the steelwork against heat build-up.
Intumescent basecoats are available in Water or Solvent based systems and when applied to correctly prepared & primed steel will offer a robust and cost effective solution for fire ratings of 30, 60, 90 & 120.
When calculating the product requirements the following key factors will apply:
Fire rating required:
30, 60, 90 or 120 minutes
Type of section:
Universal, hollow, beams or columns
Steel exposure:
Partial exposed, 3-sided or 4 sided
Size and weight of steel:
Hp/A
The Hp/A value is known as the section factor of the steel section. This section factor is directly related to the heating rate of the steel section under a fire condition.
Hp – The perimeter of the steel exposed to the fire
A – The cross sectional area of the section
The larger the surface area relative to the cross sectional area, the higher the Hp/A value, the higher the Hp/A value, the more material required. This means that the thicker the section, the slower it is to heat up consequently the less thickness of material required.

Topcoats
All manufacturers are able to offer a comprehensive range of protective and decorative topcoats to protect the Intumescent basecoat from corrosion attack and are available in a wide range of RAL and BS4800 colours. All structures have a Corrosion building classification depending on the environments they are as follows:
C1: Very low corrosion risk, warm dry interior such as offices, schools & hospitals etc,
C2: Low corrosion risk, steelwork exposed to moisture such as vehicle depots, sports halls etc
C3: Medium corrosion risk, steelwork exposed to moisture and pollution such as Breweries, swimming pools
Within a Category 1 environment a topcoat will not be required unless the Intumescent will be visible and the client requires a decorative/coloured finish.
Intumescent Compound
Intumescent compound is single part gypsum based material for sealing around service penetrations, steel pipes, steel ducts, cables & cable trays running through floors and is designed to re-instate the fire resistance of the compartment floor whilst providing an unsupported load-bearing system.
Key Features:
-
Up to 4 hours fire resistance
-
Easy, fast installation
-
Load bearing
-
Quick setting
-
Easy re-penetrable

Intumescent Coated Batts
Intumescent Batts are a cost effective, lightweight answer to most fire stopping requirements and consist of a mineral fibre board coated with an elastomeric, ablative water based sealant for fire sealing temporary and permanent multiple-service openings in walls and floors. In the event of a fire, the correctly installed batts prevent the passage of fire and smoke from the compartment wall/floor when penetrated by building services.
Key Features:
-
Up to 4 hours fire resistance
-
Easy, fast installation
-
Thermal, air sealing & acoustic ratings up to 59Db
-
Can be used for cable trays, trunking, blank openings, ducting, metal & plastic pipes

Pipe Collars / Wraps & Sleeves
Pipe collars are surface mounted whereas a pipe wrap /sleeve fits around the circumference of the pipe within the depth of the substrate. In the event of a fire both systems will prevent the passage of fire & smoke by closing off the aperture within the compartment wall/floor when penetrated with plastic pipes.
Key Features:
-
Up to 2 hours fire resistance
-
Lightweight, flexible & easy to install
-
High performance expansion rate
-
For, (but not limited to), UPVC,PVC, Metal and composite pipe penetrations
Intumescent Mastic
Intumescent mastics can be used for all building & constructions joints and normally consist of a single part; water based acrylic, (silicone available upon request) and is used to provide fire protection to gaps & movement joints. It also provides fire protection around service penetrations when used in conjunction with the Intumescent batts.
Key Features:
-
Up to 4 hours fire resistance
-
Suitable for gaps up to 50mm wide
-
Maintains substrate acoustic & air seal ratings
-
Reduces air leakage
-
Accommodates movement
