Suspended timber floors are sometimes referred to as hollow timber floors. Suspended timber floors are not the same as floating floors or raised floors.

This is a method of floor construction where timber joists are supported by load bearing walls and then covered with floorboards. The floorboards are built into (or attached onto) the joists above the foundation, which creates a gap to accommodate ventilation and reduce the chance of dampness.

= History =

This type of construction was commonly used during the Victoria era. It is still found in older buildings and is sometimes used to create a level ground floor when ground surfaces are uneven.

In the 1920s, improved construction methods resulted in refinements to suspended timber floors. Floor joists were regularly supported on honeycombed sleeper walls and joists were not in contact with external walls.

For more information on load bearing sleeper walls, see Sleeper wall

= Key points =

To prevent moisture from collecting in the gap between the floor and the building foundation, ventilation through the sleeper wall is essential. This can be accomplished by fitting airbricks or leaving half brick gaps on external walls.

Additional guidance for suitable procedures for suspended timber floors can be found in Building regulations Part C: Site preparation and resistance to contaminants and moisture. This document includes the weather-tightness and water-tightness of buildings, subsoil drainage, site preparation and additional issues relating to damp proofing and ventilation.

For more information on dealing with damp proofing, see Damp proofing buildings

= Issues of suspended timber floors =

In addition to damp, there are two common issues associated with suspended timber floors: drafts and noise.

== Drafts ==

Gaps associated with timber or hollow floors increase the tendency for drafts to occur. These can be resolved with three measures:

* Draft excluders. These include synthetic fillers and draft proofing adhesive strips.
* Insulation. Building regulations now require insulation in timber floors. For more information, see [[Floor_insulation#Timber_floors|Floor insulation]]
* Tongue and groove floorboards. This technique produces a strong bond that is suitable for floating floors. For more information, see Tongue and groove joint

== Noise ==

It is not uncommon for suspended timber floors to creak over time, especially when joists move and nails loosen. Resolving this issue can be complicated.
