The types of plastic normally used in WPC formulations have higher fire hazard properties than wood alone, as plastic has a higher chemical heat content and can melt. The inclusion of plastic as a portion of the composite results in the potential for higher fire hazards in WPCs as compared with wood. Some code officials are becoming increasingly concerned with the fire performance of WPCs.

Phononic crystals are synthetic materials formed by periodic variation of the acoustic properties of the material i.e., elasticity and mass . One of their main properties is the possibility of having a phononic band gap. A phononic crystal with phononic band gap prevents phonons of selected ranges of frequencies from being transmitted through the
The innovation was the use of a thinner, synthetic back, because of its foreseen acoustic properties. Unfortunately, the seam joining the sides to the thin back was prone to breakage. To avoid the problem of a structurally unstable seam, the engineers proposed a synthetic back with a parabolic shape. By mid-1966, according to Ovation, they .
