When constructing interior partitions, various materials can be used. These include brick, drywall, foam blocks and many others. All these materials differ in their properties, and everyone has both disadvantages and advantages. Brick partitions are quite strong, they are resistant to moisture, but at the same time they need to be plastered, and they have a fairly large weight. As for the drywall walls, they are, unlike brick, light, but they can not always hang a heavy shelf or TV. To do this, initially strengthen the mounting site with a metal frame.
