  Design Flexibility and Construction Efficiency: accel-E® Systems

When Alex E. Toye, AIA of ATA Architects of North Kansas City used accel-E® Systems to address the issue of a sloping site at the new No Frills Supermarket, he didn’t know at the time he specified the system it would also help the construction schedule with the coming harsh snowstorms in November and December of 2009.

“If we would of had an extra two weeks of good weather at the end of November and beginning of December the shell would have been enclosed much quicker,” stated Toye.

Even with the harsh weather the accel-E® S.T.E.P. system kept the project on track. The accel-E® can shorten a project’s construction cycle by as much as 66% compared to standard wall construction.

“The system goes up faster than conventional construction techniques when staged right from the plant. We also liked the fact that electrical and plumbing rough-ins were just like conventional construction. With other thermal wall composite panels on the market a hot knife has to be used to melt the insulation away to install plumbing or electrical pipes or boxes. With accel-E there is no extra steps to take and the MEP wall rough in can be started as soon as the panels are set, plumbed and secured”, said project manager John Maderak, of Darland Construction of Omaha, Nebraska the general contractor for the project.

Specially designed to maximize building efficiency, the accel-E® Steel Thermal Efficient Panel (S.T.E.P.) by SYNTHEON Inc.™ is a lightweight, easy-to-install, high performance wall system that shortens construction time, optimizes crew use, greatly improves energy efficiency in one installation process. The secret behind the exceptional construction efficiency of the accel-E® STEP panel is an exclusive manufacturing process that combines the strength and performance of cold-formed steel framing with the insulation properties of expandable polystyrene (EPS).

This unique fusion process provides each panel with the highest levels of structural strength, yet delivers thermal performance so exceptional it exceeds new ASHRAE 2007 90.1 and IECC 2009 requirements. No other wall system today combines framing, cavity insulation and continuous rigid foam insulation in such an easy, one-step installation process.

The supermarket used 25,000 square feet of the panels, 26 to 30 feet high with a panel width of 8-inches. accel-E® STEP comes in customized heights up to 48 feet and higher. It also saves time with pre-cut window and door openings to specific project requirements. Besides the accel-E system exposed smooth faced CMU was used on the South wall, along with ground faced and split faced CMU veneer, EIFS, and brick veneer to address the issue of the sloping site of the project.

Alex Toye and John Maderak of Darland Construction would use the S.T.E.P. wall system again. “Overall, the product has done what it’s supposed to do,” Toye said. “I definitely see advantages to having a full wall surface, being able to cut in openings, and do everything that the product has done. Would I use it again? Definitely I would.”

John Maderak seconded with, “SYNTHEON was very responsive in helping to facilitate and even train our erector in the field. They shipped any missing parts expeditiously. The accel-E representative spent a whole week reviewing the details with the erector and providing technical assistance. I would use this system again.”

Developed and marketed by SYNTHEON Inc., the accel-E system fully complies with both the 2006 Building Code (IBC) and the 2006 International Residential Code (IRC). Visit www.accel-E.com or call 888-9-accelE for more information.
