The first foam cement with sound-absorption efficiencymatches or exceeds commercial pu foam or organic fiber composites
Since 1995 Allied has engineered the highest-performing foam cement solutions in the industry — we are now bringing the best acoustic cement without the fire, moisture, or durability trade-offs of organic foam.
The best non-flammable foam cement in the industry with thermal insulation R/inch = 4.1 at 25 degrees C & 4.6 per inch at - 10 degrees.
In Deecember, 2025 Allied has engineered the highest thermal insulation foam cement in the industry — R = 4.1 per inch at 25 degrees C and R= 4.6 per inch at - 10 degrees. C
foam cement that achieves 4 Hours Fire Rating per ASTM-E119 .
Per ASTM E-119 Test, Allied has developed the highest fire barrier rating for A36 steel in the industry — 4 hours rating per ASTM E-119 at 1 inch thick.
The first foam cement outperforms autoclaved aerated concrete(AAC) without autoclaving
We have developed non-autoclaved foam cement significantly outperforms the AAC's in mechanical strengths, sound absorption and fire rating.
One universal foam platform, many material systems
Allied's stable aqueous foams reduce the weight of cement, concrete, ceramics, and coatings while adding insulation, fire resistance, and durability. Explore the technologies below.
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.
Foam Cement
Densities from over 1,450 kg/m³ (90 pcf) down to 48 kg/m³ (3 pcf) — for geotechnical fill, landscape architecture, lightweight roof decks, wall and floor panels, partitions, blocks, and insulative cinder-block inserts.
Flexible Foam Cement Composites
The "wood-like flexible cementitious foam" that earned the 2014 Edison Award Silver Medal. High flexural strength and clean Mandrel bending without cracking, plus strong adhesion, exterior durability, and excellent water resistance.
Geopolymer Foam
Flexible and very light — under 1.5 pcf (24 kg/m³). Various geopolymer foam composites achieve an insulative value of R > 3.8 per inch together with strong fire resistance.
Insulative Fire Bricks & Ceramics
Fired ceramic foams at densities as low as 23 kg/m³ (1.5 pcf) with excellent strength and thermal-shock resistance — durable firebricks used as high-performance insulation for kilns and incinerators.
Pervious Foam Cement & Landfill Cover
Pervious and non-pervious foamed cement for waste encapsulation, soil stabilization, and leachate filtration. As a long-lasting surface cover on landfills, ponds, and lagoons, it suppresses odors, vapors, litter, and vectors.
Twice the fire rating of intumescent coatings
Tested on identical A36 steel H-beams by a major thermal testing laboratory.
Highest strength among 35 pcf foam cements
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.
Four ways to apply fire-rated foam
Fire rated and easy to handle, ready for precast or cast-in-place manufacture — with good adhesion to steel, non-hazardous, no rust, and solvent-free.
Fire Panel — Precast (< 10 pcf)
Fire rated, easy to handle, suited to precast or cast-in-place manufacture.
Fire Panel II — 11.5 pcf (185 kg/m³)
Higher-density panel with the same fire-rated, easy-handling build.
Spray of Fire-Rated Foam
Sprayable with good adhesion to steel — non-hazardous, no rust, solvent-free.
Vertical Spray of Fire-Rated Foam
Vertical spray with strong adhesion — non-hazardous, no rust, solvent-free.
Excellent bond strength (>> 1,000 psf) of Allied 35 pcf (565 kg/m³) fire barrier foam to A-36 steel
For buildings taller than 420 feet (128 m) per SFRM — Spray-applied Fire Resistant Material.
Foam agents, composites & generators
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.
Foam Cement
90 pcf down to 3 pcf for geotechnical engineering, landscape architecture, roof decks, panels, partitions, blocks, and cinder-block inserts.
Pervious Foam Cement
Open and closed-pore structure similar to urethane and polystyrene foams — without their poor fire resistance, and with outdoor durability and cost advantage.
Insulative Fire Bricks & Panels
Strength and thermal-shock resistance for durable firebricks used as high-performance insulation in kilns and incinerators.
Geopolymer Foam
Flexible, under 1.5 pcf, reaching R > 3.8 per inch with strong fire resistance.
Fire Barrier / Firefighting Foam
Specially formulated foam used as a long-duration firefighting barrier for the containment of forest fires.
Foam Coatings & Adhesives
Controlled film thickness with improved resin distribution; foamed adhesives reduce consumption and prevent absorption by porous substrates.
AFT Foam Agents & Generators
Proven on landmark job sites
From geotechnical stabilization at the World Trade Center to green-roof fill at Harvard, Allied's foam cement performs where it counts.
Geotech fill for WTC subway stabilization
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.
Landscape architecture on the roof
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.
