SIPS Provide Dual Sound and Fire Performance

Posted on

Sound control is important in lodging structures, multi-family apartments, condominium complexes, as well as Senior Living Facilities or any building that includes dwelling units with shared walls.  Shared walls can mean unwanted noise from the unit next door and shared corridors can also mean less privacy.

For newer or remodeled multi-family housing units, Building Codes throughout Canada require a measure of sound privacy between dwelling units.  The National Building Code (NBC) specifies a minimum architectural design standard of privacy of 50 STC (Sound Transmission Class).

THE SIPS SOLUTION

Testing by an independent laboratory confirms that WEST-ECO Structural Insulated Panels (SIPs) reduce sound transmission, for a quieter indoor environment.  Certain wall assemblies using the panels achieve sound transmission class ratings (STC) of up to 58 and 59 – well above the STC 50 requirement for walls separating dwelling units.  Notably, these assemblies are also hourly fire-rated assemblies.

WEST-ECO SIPs provide builders and designers with energy efficiency, high STC ratings and hourly fire-rated assemblies in a framing system that the contractor can install very quickly.  With today’s construction labor shortages, Premier SIPs offers an exceptional system with fewer labor requirements than traditional framing products.
