How should you choose a subfloor soundproofing product?

There are many subfloor products on the market. To make an informed choice combining performance and durability, it is essential to know what to consider.

The subfloor membrane must act as a vapour barrier, since the wood reacts to moisture. To maintain its acoustic performance, the subfloor membrane must be resilient, which means it must remain stable without sagging over time.
In addition to these two essential elements, several other criteria must be considered and compared to choose the right product:

  • The installation method
  • Its compatibility with complementary products (e.g. adhesive and mortar)
  • Product knowledge of installers
  • Membrane thickness
  • Compliance with various programs (e.g. LEED and Novoclimat)
  • Results of various acoustic tests (e.g. FIIC, FSTC and Robinson)
  • The anti-fracture characteristics (for a membrane applied to ceramic)
  • Etc.
