Density of Construction Materials
The following are average densities for common construction wood sheets, 16mm thick. Density is measured in kg/m3 (LB/FT3).. obviously denser is better, as it results in less chance to flex & resonate.
Particleboard 721 (45)
MDF 769 (48)
Standard HDF 1858 (116)
Construction Plywood 577 (36)
