Fire Resistant & Energy Efficiency Building
We are a building contractor from Scotland. We have set up a couple locations in the United States building with AAC. We have been in business since 1954 in Scotland and have built mostly in Scotland & the UK, in 2015 we decided to open & build in the United States.
We offer an unrivaled range of premium products with stunning natural colors and striking finishes, designed for any project large or small.
We pride ourselves on quality, commitment, and a seamless process for our customers from beginning to end.
Here is some information about what we do:
AAC is made from fine ground silica sand, Portland cement, lime, water and aluminum powder as an expansion agent. The production process is very carefully monitored to ensure a controlled consistency in the proportions and timing of all ingredients that are used in each batch.
The materials are first mixed into a slurry and then poured into large molds where the expansion agent reacts with the alkalis in the cement and lime to produce millions of small hydrogen gas bubbles.
The mix expands and rises almost 2 times its initial volume. The hydrogen evaporates and the ‘cake’ sets up and hardens into a stable closed cell matrix which can then be precision wire-cut into blocks or panels.
The green aerated concrete is then steam cured in a pressurized autoclave for about 12-14 hours whereupon it undergoes a second chemical reaction and transforms into the mineral Tobermorite or calcium silicate hydrate. The finished materials are palletized, wrapped and delivered to the job site.
