Reduce Sound Pollution With A Roof Cover Board

There’s no doubt that modern life is noisy. Planes flying overhead make it difficult to hear anything — teachers conversing in classrooms, doctors consulting with patients, business seminars in progress, orchestras performing in auditoriums – in buildings near airports.

Noise is more than a nuisance; it has been related to stress, poor attention, sleep troubles, and productivity loss in the office, whether it’s a jackhammer outside your window, a busy freeway nearby, or planes overhead.

Sound Transmission Can Be Reduced by Using Coverboard

Why isn’t everyone doing it if there’s a simple solution to decrease sound transmission? That is an excellent question. Because, at least for roofing contractors, the answer is self-evident: Coverboard should be used.

Coverboard adds density, which helps to dampen sound. You can limit sound intrusion by adding coverboard to your roofing assembly.

Choose a coverboard that will help you get an STC rating of 60 or above.

The Sound Transmission Class (STC) is a measurement of how well a material or component blocks airborne sound. It is assessed in a specifically built laboratory chamber utilizing ASTM E90 test technique and ASTM E413 classification.

STC is a single-number rating system that is standardized. The number assigned to a material is a measure of its ability to reduce sound transmission. As a result, the greater the STC number, the better the job.

Where noise is a concern, roof assemblies should have a minimum STC rating of 50. However, I would advocate adopting a roofing system with an STC value of 60 or more to truly decrease sound transmission. That is nirvana, and the interior atmosphere will be much quieter.

What Is OITC And What Does It Mean?

Outdoor Indoor Transmission Class (OITC) measures sound transmission from the outside to the inside of a building, whereas STC measures sound transmission from one room to another. Due to the fact that outside noises have a tendency to emit

OITC focuses on measuring sounds like construction vehicles, car horns, and airplanes at lower frequencies.

OITC is a single-number rating, similar to STC. However, the OITC rating is often lower than the STC rating since it places a greater emphasis on low- to mid-frequency noises. Although OITC provides a secondary assessment, STC remains the principal approach for determining a material’s sound dampening qualities.

LEED v-4.1 Sets a Higher Standard for Acoustic Design

The quality of life in a building improves when sound transmission is reduced. The importance of acoustics to the health of persons who use a building is addressed in LEED v-4.1. The requirements for attaining the current LEED certification for effective acoustic design have gotten increasingly demanding.

Looking ahead, we should expect these standards to become much more stringent as the world’s population grows and silence becomes ever more valuable.

Reduce Noise and Strengthen Your Roof

Coverboard protects insulation, improves wind and fire protection, and improves thermal performance, among other things. In a future blog, look for more information. In the meantime, take care of yourself and don’t hesitate to contact CMAC Roofing if you have any questions.
