The Sound Test – Polystyrene Vs Wood Fibre Wall Insulation

Find out more about how we approach this building scenario.

In this video we look at the different sound absorption qualities of wood fibre insulation compared to foam insulations such as polystyrene. These two boxes have the same U-value and thickness but the sound insulation is radically different between the two.
