50%Over 50% of the installations of acoustical treatments are done after build completion, once noise has become an intolerable issue.

Most workplace environments should have quiet havens—places where private conversations can occur without being heard in adjacent rooms or passageways.

Excessive noise, and its effect on rest, are high on the list of complaints made by patients on post-discharge patient satisfaction surveys.

Good acoustics for learning support easy verbal communication, which requires low noise levels and very little reverberation.

Why address acoustics?

What is STC?

Sound Transmission ClassA numerical rating of how well a building partition attenuates airborne sound through walls, ceilings/floors, doors, windows and exterior wall configurations.Derived from standard frequencies tested from 125 Hz to 4000 Hz.

STC Rating Description Performance

15-25 Normal Speech Easily Understood Poor

25-35 Loud Speech Easily Understood Marginal

35-45 Half of Loud Speech Understood / Normal Speech Heard Good

45-55 Loud Speech Faintly Heard, Not Understood Very Good

55+ Loud Speech Usually Not Heard Excellent

Anywhere NOISE is a problem

WaveBlok™ SW

WaveBlok SW (Sub-Wall) is a highly engineered and unique sound reduction material. Wave-Blok SW is a mass loaded, flex-ible barrier designed for commer-cial, industrial, and residential applications to reduce sound transmission. It is used behind fin-ished wall or ceiling surfaces to block and reduce noise through the entire sound spectrum.

WaveBlok™ FC

WaveBlok FC (Floor/Ceiling) is a highly engineered damping composite designed to be placed onto the bare floor surface to sig-nificantly reduce noise between floors. Easily installs under all flooring including hardwood, carpet, laminate, tile and gypsum concrete.

WaveBlok™ RF

WaveBlok RF (Retro-Fit) is a unique noise reducing barrier created to go on the outside of existing walls. Easily installed, the finished surface is ready to paint.

SustainabilityThe WaveBlok family of sound control products was designed using repro-cessed materials that would ordinarily be dumped in a land fill.

All of our WaveBlok products, at end of use, are completely recyclable. If a local recycler is not capable of pro-cessing the materials, they may be re-turned to IMETCO for reprocessing.

They will be processed into “like” products and returned once again into viable sound control solutions!

IMETCO is a leading manufacturer of premier metal products for the building envelope, delivering performance-inspired systems tailored to every project. IMETCO offers a full range of high-performance metal roofing, wall, and edge systems and accessories that provide a virtually limitless realm of aesthetic possibilities.

Driven by a collective desire to provide exceptional service at every opportunity, IMETCO pledges to communicate, promise and deliver innovative solutions, dedicated support, professional engineering services, and products manufactured to the highest quality standards.
