It has been reported that solid boards perform better than hollow boards.
It should be noted though, the case is made ""based on boards of similar dimension and material make up.
The real debate should be based on the results achieved with firstly the ""base material"" and secondly the board itself, irrespective of design or material.
Facts resulting from laboratory analysis comparing board for board, show significant differences in performance.
Internal and external sources were used to conduct a range of tests, coupled with a comparison of published data.
The argument of hollow vs solid has far less relevance than material selection. The choice between recycled polyethylene as a feedstock or PVC, should be made on performance criteria. If we consider the Flexural Modulus, Bend Strength, Burning Behaviour and Tensile Creep (a critical structural test rarely given for polyethylene), then PVC based WPC becomes an obvious choice.
