Suspended Timber Ground Floor

All ground floor constructions unless very large commercial floors will require some insulation to be included within the floor zone to comply with building regulation requirements.

Suspended timber ground floor.

Different types of ground floor suspended flooring. Suspended timber floors need to have spaces underneath ventilated via air bricks through the outer walls and gaps in any internal walls so that the air can move across the building underneath the floors to prevent the build up of moisture in the timber which could lead to fungal attack. At the turn of the 18th century when construction techniques moved from boarded floors installed directly on the ground to suspended timber floors over a ventilated chamber the innovation solved a significant problem. The floor can be formed in various ways using timber joists precast concrete panels block and beam system or cast in situ with reinforced concrete.

This chapter gives guidance on meeting the technical requirements for suspended ground floors including those constructed from.

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. Suspended timber ground floors consist of the finished timber floorboards being attached to floor joists which are suspended above the subfloor of the foundation. The ends of these timber joists are built into or suspended by joist hangers from the external walls of the property. A suspended timber floor is constructed as a timber platform of boards nailed across timber joists supported on sleeper walls and the external and internal load bearing walls surrounding them.

These floor joists are raised above the subfloor on small supporting walls called tassel walls or sleeper walls.
