Fire Retardant PU Foam is a specially formulated polyurethane expanding foam designed to provide improved fire behaviour compared with standard general-purpose PU foam while also filling, sealing, and insulating gaps and cavities. It is commonly applied around doors and windows, HVAC penetrations, building joints, pipe openings, cable penetrations, cold rooms, construction cavities, and suitable fire-protection assemblies.

At Sanvil Industries Ltd, we supply quality Fire Retardant PU Foam in Kenya for construction, HVAC, refrigeration, industrial maintenance, and building-services applications. We serve contractors, builders, HVAC technicians, cold-room installers, factories, institutions, and industrial customers across Kenya, Uganda, and Tanzania at competitive wholesale and bulk prices.

Product Description – Fire-retardant PU foam

Fire Retardant Polyurethane Foam is commonly available as a single-component, moisture-curing expanding foam in a pressurized aerosol can.

After application, the material expands into gaps and cavities before curing into a cellular polyurethane structure.

It can provide several functions in a suitable installation:

• Gap filling
• Air sealing
• Thermal insulation
• Cavity filling
• Joint sealing
• Draft reduction
• Sound reduction
• Building-service penetration sealing
• Installation support
• Improved fire behaviour compared with standard PU foam

The exact fire classification must come from the manufacturer’s current technical documentation and applicable test certificate.

How Fire Retardant PU Foam Works

A typical application follows:

Foam Can → Applicator/Gun → Expansion → Gap Filling → Cure → Cellular Foam

The foam expands to fill irregular spaces and then forms a solid cellular structure.

Its formulation aims to provide improved reaction-to-fire characteristics compared with ordinary expanding foam. However, actual fire performance depends on the specific formulation and how the product forms part of the complete installation.

Applications of Fire retardant PU foam

1. Door & Window Frames

The foam fills suitable gaps around door and window frames while providing thermal and air-sealing benefits.

2. HVAC Penetrations

Suitable products can fill spaces around ducts, pipes, cables, and other building-service penetrations where the system design permits.

3. Pipe Penetrations

Fire-retardant foam can fill suitable annular spaces around compatible pipes that pass through walls and other building elements.

4. Cable Penetrations

Certain formulations can form part of suitable sealing arrangements around electrical cables and conduits.

5. Construction Joints

The material fills compatible gaps and cavities in construction assemblies where the product specification permits.

6. Cold Rooms

Suitable foam can help close gaps around panels, frames, refrigeration pipes, cables, and service penetrations.

7. HVAC & Mechanical Rooms

Contractors can apply suitable formulations around selected mechanical-service openings and installation gaps.

8. Industrial Buildings

Factories and warehouses use appropriate products for suitable construction and maintenance sealing applications.

9. Roofing & Wall Cavities

The expanding material can fill compatible gaps and cavities in selected roofing and wall installations.

10. General Building Maintenance

Maintenance teams use the foam for suitable gaps, cracks, service openings, and cavities where improved fire behaviour is desirable.

Key Features & Benefits of Fire retardant PU foam

1. Improved Fire Behaviour

Special formulations provide better fire-related performance than ordinary general-purpose PU foam, subject to certification.

2. Excellent Gap Filling

Fire Retardant PU Foam vs Standard PU Foam

A fire-retardant label does not by itself establish a fire-resistance period.

Understanding Fire Retardant vs Fire Resistant

These terms should not be treated as interchangeable.

Fire Retardant

A fire-retardant formulation aims to reduce or delay aspects of combustion or flame spread compared with an ordinary material.

Fire Resistant

Fire resistance normally refers to the ability of a complete building element or tested system to maintain defined performance for a specified period under standardized fire-test conditions.

Therefore:

Fire Retardant ≠ Fireproof

and

Fire-Retardant Foam ≠ Automatically a Certified Firestop System

Fire Rating & Certification

Fire-related specifications can include different classifications depending on the product and test standard.

A product may have documentation relating to:

• Reaction to fire
• Flame spread
• Ignitability
• Smoke characteristics
• Fire resistance of a particular joint system
• Other standardized fire tests

These are not interchangeable.

For projects that call for a particular fire rating, request:

1. Exact product name and model
2. Current Technical Data Sheet
3. Fire-test certificate or classification report
4. Tested substrate
5. Joint or penetration dimensions
6. Installation depth
7. Backing materials where applicable
8. Applicable test standard

Do not select foam solely because the can says “fire retardant.”

60, 120 & 240-Minute Fire Claims

Some fire-protection products may advertise time-based performance such as 60 minutes, 120 minutes, or 240 minutes.

Such a rating should only be stated when the exact tested system and certification support it.

The rating can depend on:

Wall/Floor Type + Opening Size + Joint Width + Foam Depth + Backing Material + Installation Method + Tested Product

Changing one part of the system can change the certified performance.

Therefore, Sanvil Industries Ltd recommends checking the current technical and fire-test documentation before specifying a time-based rating.

Fire Retardant Foam for HVAC

HVAC installations frequently create openings through walls and partitions for:

• Ducts
• Refrigeration pipes
• Chilled-water pipes
• Electrical cables
• Control cables
• Drain pipes
• Conduits

Suitable foam can seal certain installation gaps.

However, where a duct or pipe penetrates a fire-rated wall or floor, the complete penetration system should meet the project’s fire-protection requirements.

Depending on the installation, this can call for other products such as firestop sealants, collars, wraps, boards, mortars, or mineral wool.

Fire Retardant Foam for Cold Rooms

Suitable formulations can help fill:

• Panel gaps
• Door-frame gaps
• Pipe penetrations
• Cable openings
• Service penetrations
• Insulation interfaces

The foam can support thermal sealing while providing improved fire behaviour compared with standard foam.

However, cold-room panel fire performance depends on the complete panel and building system, not the expanding foam alone.

Compatible Surfaces

Depending on the product, PU foam can bond to materials such as:

• Concrete
• Brick
• Masonry
• Wood
• Metal
• PVC
• Plaster
• Selected plastics
• Suitable insulation materials

Surface preparation matters. Dust, oil, grease, loose material, frost, and incompatible coatings can reduce adhesion.

Always follow the actual manufacturer’s instructions.

Gun Grade & Straw Grade

Gun Grade

Gun-grade foam works with a compatible PU foam applicator gun.

Benefits can include:

• Better flow control
• More precise application
• Easier repetitive work
• Professional installation

Straw Grade

Straw-grade cans use an applicator tube or nozzle.

They can suit:

• Small jobs
• Maintenance
• Occasional applications
• General construction work

Expansion & Curing

The foam expands after application and then cures.

Performance depends on:

• Ambient temperature
• Surface temperature
• Humidity
• Joint dimensions
• Foam formulation
• Application quantity

Do not completely overfill cavities unless the manufacturer’s instructions specifically call for it.

Excessive expansion can put pressure on door frames, window frames, lightweight panels, and other sensitive components.

UV Protection

Many polyurethane foams can deteriorate after prolonged exposure to direct sunlight.

Where cured foam remains exposed outdoors, a suitable finishing layer may be necessary.

Possible protection can include compatible:

• Paint
• Sealant
• Plaster
• Cover strip
• Cladding
• Protective coating

Check compatibility with the exact foam.
