Fire Barrier Foam
Highest fire barrier rating per ASTM-E119 — vermiculite-free and non-hazardous. Cast as panels or sprayed directly onto steel, it protects an A36 H-beam for 4 hours to 2,000°F.
For three decades, Allied has engineered the highest-performing aqueous foam solutions in the building industry — now delivering the R-value of flammable EPS and PU foams with none of the fire risk. Cast-in-place or precast with conventional equipment.
Tested on identical A36 steel H-beams by a major thermal testing laboratory.



Allied fire barrier panels and boards show the highest compressive and bending strengths versus autoclaved and cast-in-place foam cement products, all measured at 35 pcf.
| Cement Composite | Cure Condition | Density | Compressive Strength | Bending Strength |
|---|---|---|---|---|
| AFT Fire Barrier Foam I | Room temp. | 35 pcf | 900 – 1,000 psi | 370 – 500 psi |
| AFT Fire Barrier Foam II | Room temp. | 35 pcf | 650 – 750 psi | 300 – 350 psi |
| AFT Portland Cem I/II | Room temp. | 35 pcf | 400 – 450 psi | 100 – 200 psi |
| Autoclaved Concrete | Autoclaving | 35 pcf | 600 – 700 psi | ~100 psi |
Values as published by Allied Foam Tech. Fire Barrier Foam I leads both compressive and bending strength at equal density.
All foam products are supplied in concentrated form, available in 55-gallon drums or totes. Foam generators output from a few liters to hundreds of liters per minute.
90 pcf down to 3 pcf for geotechnical engineering, landscape architecture, roof decks, panels, partitions, blocks, and cinder-block inserts.
Open and closed-pore structure similar to urethane and polystyrene foams — without their poor fire resistance, and with outdoor durability and cost advantage.
Strength and thermal-shock resistance for durable firebricks used as high-performance insulation in kilns and incinerators.
Flexible, under 1.5 pcf, reaching R > 3.8 per inch with strong fire resistance.
Specially formulated foam used as a long-duration firefighting barrier for the containment of forest fires.
Controlled film thickness with improved resin distribution; foamed adhesives reduce consumption and prevent absorption by porous substrates.
From geotechnical stabilization at the World Trade Center to green-roof fill at Harvard, Allied's foam cement performs where it counts.
A versatile, compact foam cement mixing & pumping setup — high mobility with strong output — placed lightweight geotechnical fill around the 9/11 Memorial Museum and subway structures.



The world's first low-slump geotechnical roof fill used Allied's cement composite design, foam products, and machinery. The award-winning, 530,000 ft² facility places more than half its floor area below grade and incorporates three functioning green roofs, with skylights bringing daylight underground.
