We Made the Cover!

Not all rubber underlayments are created equal

In 2007, our company went from being Dodge-Regupol, Inc. to Ecore International, LLC. Today in 2014, we are still facing many challenges related to this change. Ecore Acoustics, in particular, has been trying to clear up the confusion in the marketplace related to the QT brand of sound control underlayments. Prior to 2007, we (Dodge-Regupol) were the only company manufacturing this form of recycled rubber acoustic underlayments. In 2007, the one brand spawned 2 more competing brands. So today, those in the market for a recycled rubber underlayment will probably have to make a decision between 3 brands, all of which seem very similar: Ecore, Regupol, and Pliteq. I’ve discussed this with many acoustical consultants around the country, and for the most part, they agree that QT, GenieMat, and Regupol Impacta are equivalent products. While we can’t make any claims related to the Regupol or Pliteq brands of underlayments, we can provide information about what sets Ecore QT apart from the others to help you make a more educated decision. Similarities: Composition: recycled rubber Color: black + various color specks Thickness: various options Application: may be used under a wide variety of floor finishes to reduce impact sound transmission What’s unique about Ecore QT? Manufacturing: – Ecore QT is Made in America Certified.  +Read more about this here+. – Ecore continues to manufacture solely out of it’s Lancaster and York facilities in Pennsylvania- just as it did when it was known as Dodge-Regupol.  Our cleaning and processing of the rubber does (more…)

{Case Study} Utah Valley University Student Life and Wellness Center

Utah Valley University (UVU), a once small vocational school founded in 1941, has since expanded its mission and focus, growing into a sizeable and respectable university that fosters the education of more than 33,000 students each year. In addition to its focus on academics, UVU also recognizes the importance of recreation and athletics. In order to promote health and wellness on its campus, UVU created its Student Life and Wellness Center (SLWC). Among the SLWC’s expansive list of upgrades are three basketball courts, a climbing wall, fitness areas with cardio and free weights, a bowling alley, an indoor track, game and dance rooms, a massage room, and a reflection center. Construction of the SLWC began in September 2013, and its doors officially opened on April 17, 2014, offering its students, faculty, and staff access to a quality campus recreation facility. As stated in the SLWC’s mission statement, its goal is to “enrich the quality of life for students, faculty, and staff by providing a broad range of recreation, wellness, and student engagement opportunities that complement the academic experience.” “[The SLWC] is a state-of-the-art building,” said Kevin Hirschi, President of Mountain Heights Hardwood, the company involved with supplying the surfacing for this project. Hirschi notes that this building is truly innovative, standing at an impressive four stories tall. One of the main considerations of GSBS Architects and Jacobsen Construction, the two firms involved with SLWC’s construction, was how to reduce sound transmission from the noisy, upper-level athletic arenas to its quiet, (more…)

{Case Study} The Slate in Omaha, Nebraska

Founded in 1988, the NuStyle Development Corporation (NDC) has undoubtedly transformed and revamped the Omaha, Neb. built environment. Today, just over a quarter century later, the NDC is fully owned and operated by Todd Heistand and his wife, Mary. The NDC is most recognized for its impressive refurbishing of seemingly dilapidated properties in downtown Omaha. Throughout the years, Hesitand and their developers have compiled quite the portfolio of renovated buildings, restoring the historic value of the city and attracting commercial attention to the area. The efforts of the NDC have not gone unnoticed by the city of Omaha. In 2013, Heistand’s company was awarded the Omaha by Design’s Laurels Award, which is presented annually to “the organization or business that has made significant contributions to the creation of great public spaces in the metro.” Amongst the many remarkable buildings restored by the NDC is The Slate on N. 19th Street, featuring 117 units and costing developers $13,035,115 to renovate. In addition to the building’s aesthetically pleasing and rustic living spaces, The Slate also provides its tenants with several amenities, including a rooftop deck, a community area, and a fitness center. NuStyle developers approached ECORE International, a company that transforms reclaimed waste into unique performance surfacing, to suggest flooring options for the fitness center in The Slate. They wanted a flooring system that would prevent weight room noise from traveling to rooms below the fitness area. Choosing to start with a more conservative approach, the developers decided to use approximately 1,300 square-feet of 5-millimeter (mm) QT Sound Control Underlayment (scu), ECORE’s original recycled rubber underlayment, in The Slate’s fitness center. The floor system features a loosely bound shoe thread mat with (more…)

Need to reach a certain IIC rating? Read this before you contact an acoustic consultant.

This is something that comes up every day in my line of work: IIC [and STC] ratings of floor-ceiling assemblies.  I get calls from homeowners, architects, contractors, developers, product distributors- pretty much anyone involved in flooring whether they’re on the design side, sales side, or construction side.  Almost always, it goes the same way: Customer: I need to reach IIC — (usually it’s a 50 to reach code minimum, but sometimes it’s a 60). Which underlayment should I use? This is where I try my hardest not to sound disinterested or condescending, because I really don’t feel that way- it just requires a conscious effort not to sound robotic when you’ve gotten used to asking the same questions.  Chances are, other acoustic consultants may have a similar experience, so here’s some sound advice to prepare yourself with before you contact an acoustic consultant. IIC and STC ratings are dependent on entire assemblies, not any single element. This means that you’ll need to have all of the details of your floor-ceiling assembly before you can expect real advice from an acoustician.  Ideally you’ll have an architectural drawing calling out each element and it’s thickness in the assembly, but if not, I usually email a list like this for them to fill out: – Floor Finish – Underlayment – Subfloor system (concrete slab?  wood joist?  truss?  spacings, thicknesses, gauges, etc.) – Batt insulation in the ceiling cavity? – Resilient channels? – Ceiling details (material, number of layers, thicknesses?) The science of predicting (more…)
