Posi Joist

Multiple benefits of wooden floor elements
Posi Joist is an open wooden floor element that meets the demands for the highest sound classification. Prefast is the first producer in Sweden to offer this smart solution that appreciably simplifies building construction. One major benefit is that the beams are open, which makes it easy for electricians and plumbers to complete their installations. In addition, the structure is significantly lighter and presents a more eco-friendly construction than traditional concrete flooring.

Set to revolutionise the market
Builders in Europe have already been using this solution for quite a while, but Prefast introduced this to the Swedish market in 2021 when our new purpose built “Strut Runner” press was installed.
