- Se utilizan en lugar del hormigón armado en lugares de altura
- They are used instead of reinforced concrete in high places

ACP projected cellulosic insulation (Diffusion Magazine, 2013), is used instead of reinforced concrete for high places, for example, in movie theaters (ARQA, 2009). These partitions, made with double panels, are not more than 500 mm thick and one of the first things that was done was to reduce the air chamber to the minimum constructable, thus achieving a partition with just 460 mm thick and a weight of its own. about 125 [kg / m²], this is equivalent to a quarter of the weight of traditional concrete. These partitions, in their air chamber, use a F90 sprayed cellulosic insulation or F120 mineral glass wool. Its acoustic attenuation Rw (Baldo, 2014) is between 69 and 73dB, while those of concrete and sand are approximately 51dB.
