You can find timber suspended floors mainly in older houses in Britain. But after the Second World War, the timbers were restricted to use. Thus, other forms of building were adopted. Timber suspended floors can be used in different parts of your house.
Timber suspended ground floors: A Timber suspended ground floors contain a number of boards including tongued, well-grooved and man-made boards like plywood or timber beams. These timber beams are 15.7 inches apart and are held by timber wall plates that are adequately supported by the main walls of the house. The wall plates are bedded on the top of a proper damp-proof course.
Timber suspended upper floors: Similar to the timber suspended ground floors, the timber suspended upper floors also contain timber sheets of man-made board laid over that are supported through timber beams. Usually, timber suspended floors are at the upper level than at the ground level. They are known as single floors as the beams bridge a single cross to run from wall to wall.
The timber beams of the upper floors are bigger than the hollow ground floors as additional support is simply not possible in the upper floors. They form a bridge of narrow span across the minute part of the room. If the timber beams are more than 1.3 ft in thickness then a binder is used to support the beams. The ends of these beams are built into the walls and are supported by the hangers or fixed on the walls. The end of the timber beams which is built into the walls will be covered with some preservative to protect the timber from moist and such. Usually the roof of the room beneath the floor is plastered or fixed with the plasterboard.
Solid ground floors: This is another form of timber floor having different layers of various materials. The very first layer is made up of hardcore compositions of crushed stone and of broken brick of 3.94 inches to 5.90 inches in thickness. This is to provide a solid and level foot for the floor slab. Above this 1.97 inches thick layer of fine ash, sand and weak mix concrete is covered to bind the surface. This layer is used to give a smooth surface for bedding damp-proof covering. The damp proof covering should not be placed directly on the hardcore.
Floating wood floors: These types of floors are very fashionable and beneficial. They are not really permanent floors because they just float on top of floors that are already in place, making them very easy to lay and manage. They are not fixed, to the sub floors an anyway. There is no need of any sticking material, or nails, to fix this flooring. You can set such timber floating floors on any normal flooring.
Timber suspended floors have always been a popular method of construction and will probably be used by builders for many years to come.
