1. Task and Quality of Wooden Floors
Wooden floors are made from surfaced boards. These shall bridge
the spaces between the floor beams or fillets. The surfaced boards form a
self-contained horizontal surface which can be well walked on, receive loads and
transmit them to the subconstruction.
Surfaced boards shall be of equal thickness, as far as possible
of equal parallel width, free from knots and surfaced on one side. They consist
of soft wood or hardwood suited for that purpose. They shall be 120 to 160 mm
broad and - in surfaced condition - 20 to 24 mm thick. Wooden floors have little
dead weight, are relatively elastic and foot-warm. On the other hand, they may
be subject to deformation, because wood contracts and expands due to reception
of moisture or drying. Wooden floors are easily inflammable, they rot under the
influence of moisture and they are susceptible to destructive insects.
