Timber joists floors

Timber joists floors

Timber joists floors are very common and are still used a lot in the new construction, due to the low weight and excellent structural behaviour.
In the old constructions this type of floor is also very common and it is often preserved during renovation projects, because of its functionality and for the esthetic, very appreciated in all the markets. To grant the compliance of the old wooden floors with the most recent technical standards and regulations, very often during renovation a structural reinforcement and stiffening is adopted, through a conncected concrete layer cast in situ, specifically designed, or through the installation of a second crossed wooden board layer.
In the new constructions a timber joists floor can be designed to satisfy the most recent building regulations, through an appropriate choice of the beams and wooden boards and connecting the floor to the perimetral structures.
The acoustic insulation in laboratory has been studied on a timber joists floor of type C1, according to ISO 10140-5 (with the exception of the plasterboard ceiling mounted on wooden battens) and it is a type of floor which can be found widely in the old and new constructions.
The low acoustic performance regarding impact and airborne sound insulation of the bare timber joists floors are particularly critical, considering that the noise radiation is concentrated in the low and middle frequency range.
As a consequence, high performance materials and products have to be used, to grant the compliance to national regulation and reach a higher insulation class.
