FIRE? ASK GOVERNOR why RESTRICTION ON FIREPROOF BUILDING MATERIAL ???
WILDFIRES!
YES, MY PART OF TOWN IN SANTA BARBARA HAS BEEN TWICE UNDER MANDATORY EVACUATION IN THE PAST TWO YEARS.
LETS ASK THE GOVERNOR WHY AAC (Autoclaved Aerated Concrete) A GREEN FIREPROOF NON TOXIC MATERIAL IS RESTRICTED IN OUR STATE, WHEN 60% OF BUILDINGS IN EUROPE USE IT? (DO A STORY ON GREEN RESTRICTIONS CNN)
I asked the Governor but as a mere citizen of the state on fire, I have still gotten no reply from the "Governor Schwarznegger".
I am not with a manufacturing lobby, but a private citizen and former architect, concerned with the environment, and fire resistant building. I live in Santa Barbara, and during the Tea Fire the hill behind my house went up in flames, luckily my house was spared, when the wind changed. This personal experience has made be an activist concerning building materials.
Environmental Safety: AAC is possibly the greenest building material, comprised of plentiful natural resources, 70% air, water, sand, lime, an expansion agent and cement. No harmful emissions in manufacturing or toxic chemicals are used in its manufacture. The AAC production process requires much less energy to complete than that of other materials and the product’s outstanding energy efficient qualities makes it an excellent source of ongoing environmental conservation. AAC panels can be disassembled and reused or pulverized and recycled at the end of a building’s useful life.
AAC uniquely meets all the environmental building challenges of CA.
1. Fire Resistant: It is non-combustible (quartz sand does not burn) and emits no toxic fumes when exposed to fire. Meeting stringent building codes, by this safety feature for occupants, it could reduce insurance costs. It can be used as a cladding to protect other materials such as steel or to increase the fire rating of concrete walls. Given a 6 hour rating for a 8”thick wall of AAC. It holds the highest fire rating in industry. A house built with AAC was the only house left standing after the Laguna Beach fire in 1992
2.Pest Resistant: AAC is impenetrable by insects, termites and pests. The high quantity of Quartz sand makes it impervious to subterranean termites. This can save thousands of dollars over the buildings life on termite control and repair costs.
3. Earthquakes: (withstanding 1995 Kobe, Japan earthquake and fire). Widely approved for all seismic zones in Japan and around the world.
5. Impervious to Mold and Mildew: AAC is an inorganic mineral based building material making it impervious to mold and mildew. The American Lung Association declared it as the healthiest building material. There are no harmful VOC’s off gassing.
4. Thermal Insulation: Heating and air‐conditioning can be major cost factors in the operating expenditures of any type of building. Because of its unique physical structure, AAC provides much greater thermal insulation than conventional masonry. A bare 8‐inch thick AAC wall actually provides a static insulation value of approximately R‐8, with much higher dynamic insulation values achievable utilizing the principles of thermal mass. An analysis shows that a building built with 8” AAC exterior walls and roof slabs out performs a building built under traditional R30 insulation energy savings.
5. Acoustic Insulation: Due to its unique structure with millions of air pockets, AAC actually absorbs the sound, achieving Sound Transmission Class (STC) rating 57db. AAC panels were used as a freeway sound barrier for 25 miles in Phoenix, Arizona.
There is another test that shows it is bullet proof.
