Importance of Seal Quality

Most of the focus is on the methods of installing sound isolation products, but we cannot stress enough the importance of a fully sealed partition. As the chart below shows, the performance gains of modern sound isolation products are not achievable if the seal quality is poor.

Proper Acoustical Sealant

A common inquiry is if acoustical sealants are truly necessary to seal the assembly. We do recommend acoustic sealants because they remain flexible. This flexibility will prevent the seal from cracking over time. However, it is not necessary to utilize wildly expensive exotic materials often priced as high as $20 per tube or more. Instead, use a more traditional acoustic sealant like the GG Acoustical Sealant. GG Acoustical Sealant is water-based, low odor, easy to clean up, and dries to a non-sticky state. The cost per liquid ounce is usually the same price as a basic latex plus silicone caulk.
