What are the advantages of using suspended timber floor?
It’s easier to run wires under the floorboards of a suspended timber floor, and because it doesn’t touch the ground, it will absorb less moisture from the earth so it limits structural damage from damp which is a benefit if your home is in an area with poor drainage.
What are the advantages of a suspended floor?
Unlike standard ground floor construction, suspended floors are not sitting directly on the ground. This allows air flow and ventilation to prevent the mould and dry rot that would otherwise occur over damp ground. However this air flow can leave the problem of draughts and cold in the house if not insulated correctly.
How much heat is lost through a suspended wooden floor?
Ground-floor insulation in homes can reduce floor heat loss by up to 92 per cent. Adding insulation to suspended timber ground floors commonly found in homes built before the Second World War can reduce heat-loss by up to 92 per cent, new research has found.
What is meant by suspended timber floor?
A suspended floor means you have a crawl space underneath your ground floor. Suspended timber floors are usually found in older houses, and are normally made from timber floorboards, which are attached to the joists just above the foundations of a house.
Why do some houses have suspended floors?
Suspended concrete flooring systems were originally developed as a means of overcoming ground problems such as unstable sloping sites, where it made sense to bridge deep gaps rather than fill them. Today, nearly all new houses employ beam and block construction for their ground floors.
What goes under a suspended floor?
Building Regs for Suspended Timber Floors
- Weed prevention under the floor – concrete must be poured on the ground below a suspended floor.
- Ventilation – air bricks are required to provide ventilation from outside to under the hollow floor.
Is it worth insulating suspended timber floor?
Correctly installed hygroscopic insulation in an older property’s suspended timber floor will absorb some of the water vapour within the property during periods of high humidity (reducing the risk of condensation and mould on interior surfaces such as walls and ceilings) and release this water vapour slowly when the …
How can heat loss be reduced through the floor?
Insulation of Your Home Improving the insulation of your home is the main way to battle heat loss through floors, walls and windows and roofs. You can either install more insulation or ensure that there are no gaps in the existing insulation as adequate insulation keeps heat loss to a minimum.
What is a suspended floor in construction?
Suspended slabs are above-ground level slabs which are not directly in contact with the earth. They are commonly used to create floors for the upper storeys of houses, but can also be sat on top of pre-constructed walls to form a ground floor.
How is suspended timber ground floor constructed?
Suspended Timber Ground Floors consist of the finished timber floorboards being attached to floor joists, which are suspended above the subfloor of the foundation. These floor joists are raised above the subfloor on small supporting walls called tassel walls (or sleeper walls).
How do you ventilate a suspended timber floor?
Suspended timber floors should be well ventilated to reduce the risk of timber rot and musty smells. Ideally, there should be vents in the walls on either side of the floor to encourage cross-ventilation and minimise dead areas beneath the floor (Figure 1).
How do you strengthen a suspended floor?
Fix bouncy floors by adding bridging, adding a layer of plywood or adding a wall or beam. We’ll show you three ways to stiffen up your bouncy floor—by adding bridging, installing plywood along the joists and adding a wall or beam under the floor. Any one of the three can solve your problem, depending on your situation.
