A void is commonly used in double-story residences to remove the flooring between the lower and higher floors. As a result, a space or region where light may enter the free space is created, providing warmth and a sense of openness to an otherwise underutilized area. Void floors are typically made of wood, although other materials such as concrete or glass are also used. The word "void" comes from the same source as the word "vault," which is why void floors are also called vaulted floors. Voids can be found in old buildings and even some new ones that were built without any thought of modern design principles. However, they are not required by law to be included in newly constructed homes. Voids provide many benefits for homeowners and their families. First of all, they allow for more privacy than a house with no void floor would offer. If someone was to walk into your home's living room and see the floor-to-ceiling wall of windows, they might feel as if they were being watched or intruded upon. By including a void floor, your family's privacy is protected because people cannot see down into the room. Secondly, void floors help reduce noise pollution in bedrooms by acting as soundproof dividers between rooms. If you share a house with anyone else, you know how difficult it can be to get a good night's sleep when someone else is constantly moving about the house.
