Soundproofing Strategies in Multi Unit Homes: Insights from Multiplex Builder in Burnaby
Soundproofing Strategies in Multi Unit Homes to Ensure Tenant Satisfaction
As urban density increases, so does the expectation for quiet enjoyment. Tenants are more aware of acoustics and willing to pay a premium for peace. Failing to address noise transmission leads to higher turnover, negative reviews and a devalued asset.
Proactive Soundproofing as a Core Strategy
Integrating noise abatement strategies from the initial design phase is the most cost-effective approach. Addressing acoustics during construction rather than through a later renovation saves significant capital and ensures superior performance. As an experienced Multiplex Builder in BC, Haute Living prioritizes acoustic comfort from day one, ensuring your multi-unit project meets modern tenant expectations and enhances overall livability.
Beyond soundproofing, we also focus on other essential elements like high-efficiency HVAC systems, quality insulation and proper ventilation for energy efficiency and long-term durability. A well-built multiplex isn’t just about maximizing space — it’s about creating a home that’s quiet, comfortable and fully optimized for modern living.

Understand Sound Metrics: STC and IIC
STC (Sound Transmission Class)
The STC rating measures a partition's effectiveness at preventing airborne noise such as speech, music or television sound from passing through walls, floors and ceilings. A high STC rating indicates excellent sound-blocking capability and is essential for tenant privacy and comfort. BC Building Code requires a minimum rating of 50 between dwelling units, but STC55 or 60+ will be more desirable standard for improved comfort and privacy.
IIC (Impact Insulation Class)
The IIC rating evaluates a floor or ceiling’s ability to insulate against impact noise, like footsteps or dropped objects. High IIC ratings contribute to a quieter living environment, vital in multi-story or multi-unit buildings. The British Columbia Building Code (BCBC) does not have a mandatory minimum Impact Insulation Class requirement for floor/ceiling assemblies. Instead, it uses a recommended criterion that bare floors should achieve a minimum IIC of 55 when tested without a floor covering.
Identifying and Sealing Flanking Paths
Noise isn’t just transmitted directly through walls and floors, but also through flanking paths. Flanking paths are indirect routes like ductwork, joist systems or gaps around installations. Addressing these paths by sealing joints, using acoustic sealants around door frames and tightly enclosing ductwork is vital to a comprehensive soundproofing strategy.
Advanced Material Solutions for Enhanced Soundproofing in Multi-Unit Homes
Viscoelastic Damping Compounds: Utilizing noiseproofing materials can significantly enhance STC ratings. This compound is applied between layers of building material (e.g., drywall) and it works by turning sound energy into heat, effectively dampening vibrations and noise transmission.
Effective Use of Mass Loaded Vinyl (MLV): Mass Loaded Vinyl is a robust barrier that increases mass to prevent sound propagation. Its flexibility allows for application on walls, floors and ceilings, making it a versatile solution to reduce both airborne and structure-borne noise within a multiplex setting.
Integrated Acoustic Systems: By combining elements such as isolation clips, resilient channels and specialized insulation provides a significant reduction in both airborne and impact noises. These systems are especially beneficial in maintaining peace and quiet throughout the building.
Ensuring Optimal Sound Absorption: While blocking noise transfer between units is crucial and addressing internal sound quality through absorption is equally important. Installing acoustic panels in communal areas or units reduces echo and reverberation that creates more pleasant and relaxed living space.
