For the Richmond semi we are investing in considerably more sound wall insulation as a means of ensuring our future clients will have a better experience living in the homes. Sound mitigation is a tough issue. Basically any sound transfer is a failure in the perspective of our buyers. They want a home completely removed from any neighboring noise. Having the crews on site actually detail the middle wall properly is an issue. Despite the lab results on these wall assemblies, the actual practice of how the houses are built leads to inherently flawed sound mitigation. I can only imagine how shoddy other builders sound performance must be vs the wall assembly we are using now. On the main floor there are 4 stud framed walls, each cavity is filled with roksul and each of the four walls is detached from the next. Various layers of drywall are used to prevent sound and fire transfer. Once this wall is complete we will perform some tests to see how we’ve done.
Sound insulating wall is going in.
