... I was home and asleep when the fire started. It burned 1/3 of our roof off. ... During the blaze, the 3X12s burned nearly completely through above the air krete insulation. I definitely believe that the fire break that the Air Krete® provides is what prevented the collapse of the roof into the living space and allowed me the time to put out the blaze. Read more (pdf)

How Stuff Works 10 Fun Facts

How Stuff Works Air Krete dries to a rigid foam, trapping its many millions of air bubbles inside. Done right, it also keeps unwanted temperatures out while keeping the climate you want inside. Just ask Al Gore, the Audubon Society and the Biosphere II preserve -- they've all used Air Krete in construction projects. Read Review

Building Green's Review
Air Krete was recently reviewed in a less than positive manner in an article written by Tristan Roberts, Editorial Director of Building Green Inc. Attached find “What About Air Krete?” A Deeper Look at the Insulation Alternative. Please review… We would like to take this opportunity to respond and comment on the contents of the article. In a continuing effort to improve the Air Krete Product, research and development has been ongoing for the past several years. Due to Equipment and Product modifications, we developed a “NEW” Air Krete “Greensulation” Product that looked like a winner to us. Read More.... UPDATE R VALUE ASTM TESTING

Cementitious Foam insulation is made from magnesium oxide that is derived from sea water and blown in place with air. No CFCs or HCFCs are used. Because of its inorganic composition, it has very low VOC emissions, is totally inert, and non-combustible. Cementitious foam insulation is available commercially in one product: Air-Krete. There is one installer of this type of insulation in our region. This type of insulation is considered the most benign from an indoor air quality standpoint; it is also more costly.

Cementitious Foam Insulation, including Airkrete, is made from inert materials and considered non-toxic. It's a professionally installed foamed-in (injected) product and a very effective insulator. More often used in commercial buildings. Read more...

Air Krete® is a non-toxic insulation that is easily inserted into open and closed cavities such as walls, roofs, and ceilings. Air Krete is installed as a foam with the consistency of shaving cream, which then hardens into a stable foam. It has a high thermal efficiency, is sound-absorbing and fire-proof.

Non Timber Building Materials...

A non-toxic insulating foam called 'Air-Krete', is now marketed in the U.S. as an alternative to fibreglass insulation. Air-Krete is made from tiny magnesium oxide bubbles which encapsulate atmospheric air. Magnesium oxide is a natural mineral used for centuries to make fire bricks. Its higher cost is offset by its superior thermal qualities.
E Magazine
While newer and less well known, Air Krete is a thermally efficient and non-toxic spray insulation that is easily foamed into open or closed cavities in walls, roofs and ceilings. The product's basic raw material components are air, water and cement which, when combined, create a cost-effective, safe and high performance product. The National Audubon Society installed Air Krete in its New York City headquarters as part of an overhaul designed to "green up" that organization's entire operation.
Bob Vila
Bob Vila talks about AirKreteCementitious foam is a magnesium-based product that is derived from seawater. Because of its consistency, foam is the most effective product for retrofitting into existing walls. Foam will work its way around any obstacle, providing a near-100 percent wall fill (cellulose, for example, may not fill completely around bundles of wires or pipe runs and leave random voids). Unlike bottled foam insulation used to seal small gaps around pipes and wiring, it does not shrink or expand. In new construction, foam can be installed after drywall is hung, but taping and texturing drywall joints should be completed after the foam has completely dried (usually about 48 hours). Cementitious foam is the most costly insulation to retrofit, but is the most benign in regards to indoor air quality; when it is being applied into a wall there is no dust. It sounds like the perfect insulation. With an insulating value of 3.9 per inch, it would exceed R-21 in a 2x6 wall. It completely seals the cavity preventing air leaks. It doesn't shrink. It won't burn or attract pests. It's non-toxic and popular with "hyper-sensitive" people. Read more...
Building Green
Air Krete has gained a following both for environmental and health reasons. It is an inorganic foam produced from magnesium oxide (derived from sea water). It is foamed under pressure with a microscopic cell generator and compressed air; no CFCs or HCFCs are used. Because of its inorganic composition, Air Krete has very low VOC emissions, is totally inert, and non-combustible. It is foamed in place in closed wall or masonry block cavities, or behind mesh in open cavities to form a lightweight and rigid, but very friable, foam.
Thorpewood Org
Air krete is 100% non-toxic, free of CFC's and formaldehyde, free of asbestos and all other carcinogenic fibers. It is odor- free, has a high R-value, has no loss of R-value over time (non-shrink, non-settling), fireproof, with no by-products of combustion.
