Light-wood framed construction remains one of the most popular methods for building homes and low-rise apartment buildings in North America. With the advent of new wood construction techniques such as cross-laminated timber (CLT), unforeseen sound transmission paths can compromise acoustic performance as well as compliance with Building Code and other contractual requirements. The resurgence of older techniques, like nailed laminated timber (NLT), can have similar consequences.
The use of exposed wood ceilings, for example, often limits sound attenuation performance of party walls built up to the wood ceiling. Impact noise transmission levels may be higher than anticipated, resulting in owner/occupier dissatisfaction.
BAP Acoustics provides expert advice in the design and construction of wood-frame as well as concrete buildings including multi-family dwellings, schools, and commercial developments. By acoustically designing the connection details, flanking paths can be minimized through exposed wood ceilings, ensuring that CLT floor construction assemblies not only meet but exceed Code in line with high-end condo buyer expectations.
We also worked exclusively with a BC developer to design uprated wood-frame separating floor assemblies for rental suite accommodation. Our solution delivers a high level of impact sound attenuation as well as significantly exceeding related Building Code requirements.
