SHORT DESCRIPTION:

• Wooden floors are standard constructions in all parts of the world.

• They are principally made of wooden planks, nailed onto a sawn timber sub-structure.

The smaller the distance between the members of the supporting structure, the stronger the floor or ceiling and the less the vibration and sound transmission, but also the higher the costs (as more timber is needed).

• Protective measures against biological agents and fire are essential (see section on PROTECTIVE MEASURES).

• The illustrations on the next three pages are taken from the excellently illustrated UNIDO

Manual on Wooden House Construction, which was prepared by the Instituto de Pesquisas Tecnologicas (IPT), Sao Paulo, Brazil, for a self-help community building project at

Coroados, Manaus, under a contract with the Housing Society for the Amazon State (SHAM).
