Townsend Library

True Noise Reduction with the appearance of textured plaster. Another example of the new SonaKrete product from International Cellulose Corporation that really requires a site visit to appreciate it. Applied in 4 continuous coats and troweled between each layer, SonaKrete is one of the first spay-on products able to provide true sound absorption without the spray-on texture that it is always associated with. Applied at 1/2" with N.R.C. Ratings of .65, SonaKrete is sure to be a favorite of acoustical engineering firms.

Pathfinder Voc-Tech School

A safe and quiet environment for the students in the automotive and electrical shop at Pathfinder Voc-Tech High School in Palmer Massachusetts. Originally spray applied with a mineral fiber acoustical product, the ceiling was constantly flaking the itchy and irritating material. K-13 being a truly green recycled cellulose product, is now providing effective sound control along with bond strengths in excess of 250 pounds per square foot. Flaking and dusting are no longer an issue.

Phillips Academy

This striking before and after is a renovation of an old hockey rink converting it into a comfortable dining facility at the Phillips Academy in Andover Massachusetts. With minimal surface preparation, Light Grey K-13 was applied at 2.76", providing an R-value of 13 along with the superior acoustical performance of a Noise Reduction Coefficient of 1.00. Costs, aesthetics and thermal performance in a one pass application certainly highlights this multifaceted K-13 application.

Wesleyan University, Usdan Universiy Center

Wesleyan University receives a second application following the walls at Fayerweather Hall. Usdan University Center houses this large open cafe with ceiling heights of over 20 feet. Acentech Incorporated, knowing acoustical performance would be paramount, utilized SonaKrete for another application to control reverberation within the space. Applied at .5”, the SonaKrete is providing a Noise Reduction Coefficient of .65 along with the aesthetics of a flat plaster look finish.

Brown University, Sharpe Refectory

Acentech steps forward at Brown University specifying the recently released Sona-Krete troweled finish acoustical product from International Cellulose Corporation of Houston Texas. This recently renovated 10,300 square foot cafeteria would grow to a deafening roar when filled to capacity, drawing complaints from diners and staff alike. A high end aesthetic finish was paramount for the owners. Sona-Krete was applied at at thickness of .5" providing a Noise Reduction Coefficient of .80. The results were remarkable, just ask the staff.

St. John's Preparatory School

Invited back for a return performance. Sona-Spray "fc" is reapplied at the Saint John's Preparatory School in Danvers Massachusetts. Originally applied in 1991, the school thought it was time for a face lift. A change in color, lighting, and a new custom color, Sona-Spray "fc" will provide a bright new atmosphere for student lunches. The new acoustical application was applied over the original 1/2" in just under two weeks time during a school vacation.

Clark Lane Middle School

Another custom color application! Fletcher Thompson, Inc. selected special color Sona-Spray "fc" in Ivory Tusk for the new addition to the Clark Lane Middle School. The multipurpose use of the space, which includes a stage, insures that whether it be lunch, a school dance or an assembly, reverberation will not be a problem. Phase 2 of the project includes a gymnasium which will also receive the custom Ivory Tusk color.

Merrimac Public Library

Large refurbished timbers frame this .5" application of Sona-Spray "fc" at the new Merrimac Public Library in Merrimac Massachusetts. The unique design of a modified post and beam structure required a high performance acoustical material for the cathedral ceiling areas. A Noise Reduction Coefficient of .65 has kept reverberation in check while offering a dramatic backdrop for all the wood finishes on the project.

Portsmouth High School Cafeteria

This open air cafe-type setting is actually the cafeteria at another Cavanaugh Tocci Associates application at the new Portsmouth High School in Portsmouth New Hampshire. K-13, applied at 1.5", Noise Reduction Coefficient of 1.05, is reducing reverberation in what is normally a deafening environment in schools. Along with controlling the acoustics, the K-13 visually softens the exposed fluted metal deck improving aesthetics.

Portsmouth High School Music Room

Cavanaugh Tocci Associates Strike again with multiple applications of K-13 in the new Portsmouth High School in Portsmouth New Hampshire. This month's profile highlights the new music room recently completed. In conjunction with cloud diffusers, the application of 1.5" of Light Gray K-13, Noise Reduction Coefficient of 1.05, gives the space just enough brightness for band practice without the reverberation that would destroy the sound quality.

Charles River School

Sloped cathedral ceilings in every classroom mark the design of he recent expansion of the Charles River School in Dover Massachusetts. Sona-Spray "fc" was selected for its high performance and monolithic application. Applied at 1/2", over OSB, Sona-Spray "fc" provided a Noise Reduction Coefficient of .65 with a GE light reflectivity of .85. The application allowed the architect to control reverberation without detracting from the architectural design of the structure.

High Mowing School

This spectacular post and beam style construction is the new home for the High Mowing School in Wilton New Hampshire. Selecting K-13, applied at 2", not only provided superior Noise Reduction Coefficients of .95, but also concealed all conduit and wiring that was flush mounted on the drywall surface. The spray applied application also allowed the architect's design freedom without detracting form the appearance of the structure.

Barnstable Middle School

Overcrowding in our schools over the past 10 years has become a major problem. The proof is in this recent application of 1" of K-13 Beige to a former wood shop ceiling that now has been transformed into 3 classrooms for teaching English. The partition walls, that do not go all the way to the ceiling, in conjunction with the original black concrete ceiling, were creating reverberation across the entire area making it almost impossible for students to concentrate. The application provided an N.R.C. Rating of .95 along with some much needed light reflectivity.

Dartmouth High School

Following last year's before and after Project Profile at the Cushman School, September 2002, Dartmouth School System looked for another opportunity to utilize K-13 for its multi-use application. With the old drop ceiling removed, the joists received a fresh coat of paint in the school colors and the application of 1.5" of white K-13 was the finishing touch. The teaching staff has never been more willing to have cafeteria duty now that the 4 second reverberation time has been drastically reduced.

Babson College Gerber Hall

With the renovations and additions of audio/visual equipment to this classroom at Babson College in Babson Park Massachusetts, the concrete plank ceiling looked more like a maze of conduit in a mechanical room than a classroom. Facilities Management chose Sona-Spray"fc" to improve the aesthetics along with the dramatic acoustical improvements. Following this application, A.T.I. has been called back to do a conference center and an additional classroom. There are also two more classrooms planned for this year's summer break.

B.S.C. Academic Achievement Center

Sona-Spray "fc", applied to a minimum thickness of 1/2", was the material specified to control sound deflection in this newly renovated study hall at Bridgewater State College. The concrete waffle had to be dealt with if the ceilings were to remain exposed and the Architects Forum of Newton Massachusetts had the answer. The contrast of the exposed edges and the Sona-Spray "fc" within the waffle created a sharp clean appearance.

Providence College, Slavin Hall

The once popular concrete waffle construction has been notorious for creating echo cambers throughout colleges across the county. Providence College, along with several others, have found the cure. Sona-Spray applied a .5” Noise Reduction Coefficient of .65 can be applied to the bottom as well as the sides and top of the pan providing 2.5 times the floor space of acoustical material. This drastic application transforms this space from a cave to classroom in 1 day while improving the atheistic from the rough concrete surface.
