THE CHALLENGE
Recognizing the need
for increasingly energy efficient building envelopes and aware of
the shortcomings of products currently on the market, the inventors
and patentees of air krete have developed a product
which eliminates or mitigates those shortcomings while maintaining
a high degree of thermal efficiency.
In air krete,
its inventors offer the construction industry a product which is:
- Fireproof, non-toxic
and does not shrink
(unlike "plastic" chemical based foams or boards)
- Incapable of producing
airborne lung irritants or contaminants
(unlike man-made fiber based products, i.e. fiber glass)
- Fireproof with low
absorption of moisture
(unlike fiber based products)
- Continuous, and non-settling
(unlike loose fill or foam plastic inserts)
- A highly effective
sound absorbing acoustic insulator
- An excellent material
for firestopping and firesafing
- Ideal for high and
very high temperature installations
- An insulating encapsulator
of hazardous materials

APPLICATIONS
(New & Retrofit)
- Masonry: foamed in
place at block cores and cavities between wythes.
- Studs, metal and
wood: foamed in place through or behind appropriate screening
to completely fill air spaces.
- Curtain walls: foamed
in place to firestop spandrels and insulate between exterior skin
and interior finish.
- Deck insulation:
foamed in place through or above appropriate screening to provide
insulation on the warm side where it belongs.
- Pipe chases: foamed
in place to avoid condensation, insulate, firestop and greatly
reduce sound transmission.
- Partitions: foamed
in place to increase fire resistance rating and reduce sound transmission.
- High temperature:
inorganic, fireproof nature of material produces a low cost, high
performance application.
- Encapsulation: where
space and configuration permit, encapsulation of existing asbestos-containing
insulation with air krete inexpensively increases
insulative efficiency rather than expensively replacing it.

THE PRODUCT
air krete
is an ultralight insulating foam consisting of a patented combination
of an inorganic cementitious stabilizer, a microscopic cell generator,
a catalyst, and compressed air designed to create an effective,
safe, thermal, acoustic and fireproof insulation for use in many
architectural and engineering applications.
AVAILABILITY
air krete
is available through licensed manufacturer and/or its trained
dealer/installers.

- Fire Characteristics
- ASTM E84.81A
Test extended to 30 minutes with no further flame progression.
Flame spread: 0
Smoke developed: 0
Fuel contributed: 0
- Dimensional Stability
- ASTM C951
Shrinkage: 0
- Ultrasafe Material
- independent tests and certifications are available indicating
that air krete is free of carcinogenic mineral fibers,
including asbestos and fiber glass; formaldehyde; chlorinated
fluorocarbons. It is 98% or more inorganic; contributes no harmful
gases under flaming and smoldering test conditions and is non-hazardous
as waste material.
- Sound Absorption/Transmission
- preliminary tests indicate significant improvement in the sound
performance of structures insulated with air krete.
