One of them is foam block. What is it? This is a mixture of concrete or cement mortar with sand and a special protein substance. This material when solidified forms a substance with a uniform distribution inside small air bubbles. This makes the foam block good and sound insulator, as well as quite lightweight in weight. In addition, foam blocks also have additional characteristics that distinguish it among other materials. For example, wood is easily lend itself to fire and rotting. But there is no foam block. Agree that in a bathhouse in which humidity and high temperatures are constantly present, it is better to have an additional source of reliability. All these factors make the interior decoration of the bath foam blocks very attractive. It is worth noting the minus of foam blocks — this material is not moisture -resistant, therefore it will need to be protected from moisture. Typically, for this, baths are plastered inside or use wood, or ceramic tiles.
