Things to consider when planning your project

Sound Control is not a visual part of the upgrades for your home it is often neglected during the planning and construction phase, but home buyers should expect and demand it as part of their investment. Sound control enables you to enjoy a comfortable, relaxed living space without all the outside noise and distractions. Homebuyers nationally said unwanted noise in their residences is of significant importance, according to the annual REALTOR® Home Features Survey. It will also increase the value of your home.

Consider the following:

  • Exterior Walls, are a source for outside noise such as airplanes, firetrucks, ambulances, etc. Rockwool Premium Plus™ Insulation has an STC rating of 58* in a brick veneer exterior wall assembly.

  • Using Rockwool in interior walls never get the consideration they need until it is too late. Noise from game rooms, home entertain rooms, and kids room can ruin a good nights rest which studies have shown can contribute to irritability and bad health. With STC ratings as high as 56* in a standard 2 x 4 wall assembly Rockwool Premium Plus™ Insulation has set the standards high.

  • Insulating plumbing walls can stop the dreaded toilet flush noise and help maintain privacy.

  • Insulating the mid-floors of a home or multi-family housing can reduce the noise from above as well as the impact noise associated with footsteps.

  • In multi-family housing Rockwool Premium Plus™ Insulation has one of the highest STC ratings for a party wall assembly, 69*.
