YTONG is a lightweight cellular concrete material made of sand, water and air. In addition to being resistant to hurricanes, earthquakes and termites, YTONG also claims to be exceptionally fire resistance. According to the YTONG website, the physical properties of YTONG materials make it the ideal formula for protection against fire as it is non-flammable.
The filled cells that form during the manufacturing process give the product thermal insulation properties. According to University of Hawaii Architecture Professor Martin Despang “We want walls that keep us cool and this is one way to actually do it. To have this concrete that is sort of fluffy and aerated” (KITV). The company claims that it’s unnecessary to provide additional insulation, since YTONG prevents the entry of heat, making it warm in winter and cool in summer.
Sound insulation is an added benefit. The sound in a room reflects less off the walls, which reduces the reverberation (echo) in the space. The surface of YTONG walls absorbs noise into its numerous partly open cells.
This durable, lightweight construction material’s cellular structure is formed during the manufacturing process. As a result, the density of the product remains minimal. This makes the product lighter and easier to install.
Ecologically the insulating power could make YTONG a serious energy saver, and since energy consumption during the manufacturing process is very low, the environment is less polluted. Manufacturing this construction material the production requires few raw materials. Its elements are water, high quality chalk and finely ground sand and Portland cement.
