These floor joists are raised above the subfloor on small supporting walls called tassel walls or sleeper walls.
We explain how hollow or suspended floors are made and what the key building regulations that affect them are.
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.
This chapter gives guidance on meeting the technical requirements for suspended ground floors including those constructed from.
There are 2 types of floor construction used in the building industry today.
These can be classed as either suspended or solid.
Unlike standard ground floor construction suspended floors are not sitting directly on the ground.
1 suspended timber floor construction there are several different types of suspended timber ground floor construction.
Suspended timber ground floors consist of the finished timber floorboards being attached to floor joists which are suspended above the subfloor of the foundation.
Supports underneath the floor are permanent and include sleeper walls or timber props placed at regular intervals.
Suspended timber floor as a requirement of the building regulations the structure should be protected against the growth of weeds and other plant life.
The ground floors in most medieval domestic buildings were simply compacted earth.
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.
Previously floor timbers had been prone to damp and rot thanks to their direct contact with the moist ground.
The ground should have a layer of concrete poured across and there should be a ventilated gap of at least 150mm between the underside of the timbers and the concrete to prevent moisture.
Solid floors are a lot more substantial and require the ground to be made up in layers of ground sub base sand compacted hard core damp proof membrane insulation and concrete.
These vary depending upon the age of the building its structural form limitations of the timber available and the local traditions.
Concrete vs timber floors.
