R-Control Structural Insulated Panels Improve Insulation and Acoustics at KREX-TV

DENVER, CO--(Marketwire - April 5, 2011) - R-Control® Structural Insulated Panels (SIPs) were used to rebuild a fire-damaged TV station in Grand Junction, CO. In December 2008 a fire in the KREX-TV studio broke out as a result of an electrical problem. The building was damaged beyond repair. Ron Tillery, studio manager, seized the opportunity to build a new studio.

The new studio would be more energy-efficient and correct a longstanding problem with noise coming from a helicopter pad on the roof of the neighboring St. Mary's Hospital, the largest hospital in the KREX area. "Our studio was right in the line of flight for the hospital helicopter pad, and the noise was a problem for us for years," said Tillery. "We set out to build an entirely new studio that would improve our facility in every aspect."

Tillery wanted to insulate the studio for heat as well as acoustics. "We told the architect we wanted to have the best possible acoustics and energy efficiency in our new building. They suggested we use ACH Foam Technologies' SIPs for the roof. The panels are already sandwiched with R-38 EPS insulation and ready to put in place, and our architects felt the SIPs would give us the best thermal insulation available." SIPs also offered acoustical benefits because of the airtightness of a SIPs-built building.

According to Frank Kiesecker, VP Sales and Marketing for ACH, SIPs work well for blocking out mid- to high-range frequencies that are airborne. "Low frequency noise would be best handled by a heavy, dense material like concrete," explained Kiesecker. "But concrete roofs require a difficult, more complex construction. In the case of KREX, the helicopter noise was of a higher frequency, so the SIPs were able to block out some of the noise from the sheer airtightness of the SIPs connections."

According to Tillery, although none of the construction crew had worked with SIPs before, there were no problems with the installation. "We broke ground in late November of 2008, started moving throughout the winter, installed our new set and technical equipment in the spring, and did our first high-definition broadcast on August 10, 2009," said Tillery.
