Located in Central Oregon, proudly serving the Pacific Northwest.
The photos above show an AAC structure in Kobe after the earthquake. The other homes were all leveled by the earthquake or destroyed by the fires that followed. This AAC building is actually moved off its foundation, but the walls are still intact.
AAC has an extremely high strength to weight ratio. The dimensional stability and compressive strength allows AAC building blocks to be used in both load bearing and non-load bearing applications. AAC is installed using a thin bed mortar. When installed properly, the resulting wall functions as a monolithic structure. The blocks are available in a number of different densities, resulting in a product that can easily be modified to meet any specific application requirements. Depending upon density, AAC provides compressive strength of 290 psi to in excess of 1000 psi. AAC has been used in seismically active and hurricane prone regions around the world. Buildings constructed of AAC are able to withstand wind forces exceeding 170 mph. The strength and resiliency of AAC is best exemplified by the survival of all 5,578 homes during the Kobe, Japan earthquake in 1995, which damaged or destroyed over 106,000 buildings.
Unlike most building materials used today, AAC is 100% inorganic. In climates where termites and other insects flourish, AAC is the perfect application as pets cannot eat it. Its solid construction also alleviates voids where pests can live and colonize. AAC's inorganic properties leave no nutritional value for molds and fungi to thrive, leaving it the perfect material of use in wet climate areas, which is an important consideration in todays air tight buildings.
Sound barrier wall built in 2012 in Hawaii along a busy highway. Wall was built using 8" block application.
AAC has been proven to drastically reduce the impact of noise pollution, both inside and outside of a structure. The materials sound insulation properties exceed all other building materials of the same weight per surface area on the market. Its noise reduction coefficient is more than seven times that of ordinary concrete. The STC (Sound Transmission Class) rating of an 8" thick AAC wall ranges from 44-50 STC depending on the finishing material (stucco, plaster, drywall, etc.). AAC panels and block have been used in states such as Georgia, Hawaii, and Arizona, as sounds barrier walls for hundreds of miles of noise polluting highways.
A picture is worth a 1,000 words: only house to survive this Laguna, California fire in 1993 was an AAC house
Every year hundreds of homes are lost, and thousands more threatened by the roaring wild fires that rip through the Pacific Northwest. Hundreds of tests, studies, and real life scenarios have proven the benefits of AAC as a fire resistant material. With AAC being non-combustible and inorganic, it makes it one of the highest hourly fire resistant materials per inch of building material in todays market, with the melting point of +2900 degrees F.
Walls constructed of AAC maintain their structural integrity, providing occupants to escape, and reducing the danger of collapsing for firefighters. As AAC is a monolithic (one complete) structure, any organic materials may burn, leaving the AAC fully intact. In the event of a fire, AAC inhibits the spreading of flames within buildings and/or between individual structures. With this, AAC is ideal for any fire related application, such as; fire walls, elevator shafts, column wraps, and subdivions with homes in close proximity.
AAC is made of a few very simple ingredients; sand, cement, lime, and water. During the manufacturing process these naturally abundant materials are used to make a non toxic, non pollutant, 100% recyclable product. AAC is a true "green" material and can earn many points in a LEED certification (with proper instillation) in the VOC's category as AAC contains little to no volatile organic compounds (for more information on LEED's please visit our LEED certification link above).
