Everywhere in the world, small cellular glass companies are popping up. Most of them are based on direct foaming of recycled glass. Taiwan is another example with Taiwan Material Development Co., Ltd.
This company describes themselves in the following way:
Innovation, Green energy, Quality, and Service are the purpose of Taiwan Material Development Co., LTD, and become the greatest sustainable operation green material industry is our goal. We provide high quality construction and guarantee in building material, construction, techniques, and after-sales service, and also reduce the waste of energy resources. We provide a healthy, environment friendly, convenience and high quality functional material. TWMD introduce AH lightweight solid wall to market, and provide users the internal wall partition with all function. On the other hand, we keep developing related green building materials. Look forward to developing a complete production system. To build a green building material brand. Hope to satisfied architects, interior designers, businesses of related industries and ordinary people by doing one-stop shopping.
They describe their product as a Lightweight Insulation block, foamed from LCD glass, obtained from Spring Pool Glass. This means that they are foaming a borosilicate glass. This kind of glass has a lower thermal expansion coefficient and higher chemical resistance, which means that this product can withstand more than standard cellular glass. It is not clear how this glass is foamed because LCD glass does not contain sulphate because it is sodium free. I guess it will be carbon black and Antimonytrioxide.
The product is nevertheless promoted as a typcial building material and not an industrial one. The boron in the glass gives other perspectives. As end of this post, I give you also the link to some movies about this product: 1, 2 , 3, 4 and 5. The last one seems to be the best one. In this movie, the use of cellular glass as an acoustic screen is mentioned.
