  Construction Efficiency, Energy Efficiency, Labor Efficiency… All in One STEP

Over the past few decades, the quest for more efficient building envelopes has produced significant developments in structural wall panel systems, but few provide the energy efficiency, construction efficiency and labor efficiency of the accel-E™ Steel Thermal Efficient Panel (S.T.E.P.) wall system.

accel-E™ S.T.E.P. panels are fabricated using a proprietary technology that fuses cold-formed steel framing members and expanded polystyrene (EPS) insulation. Thus, framing and insulation are contained in a single system – and installed in a single step.

Thermal slots in the specially shaped steel studs optimize structural and thermal performance, and the panels themselves lock together to minimize air intrusion and insulation gaps. Window and door openings are pre-cut, and pre-punched openings simplify installation of electrical, plumbing and mechanical systems.

The accel-E™ Steel Thermal Efficient Panel (S.T.E.P.) wall system is fabricated by fusing cold-formed steel framing members and expanded polystyrene (EPS) insulation. Framing and insulation are contained in a single system, and installed in a single step thus reducing labor costs and offering superior energy-efficiency.S.T.E.P. Energy Efficiency
Tests have shown the effective R-value performance of a conventionally installed wall system can be significantly below the stated R-value of the insulating material. The loss of insulation efficiency is due to various factors such as framing members in the open cavity, air infiltration, moisture impact and insulation irregularities, installation flaws and gaps.

By fusing framing members and insulation together into a continuous system, accel-E™ S.T.E.P. panels provide superior energy efficiency while greatly reducing air infiltration. In addition moisture absorption problems are also avoided, since the steel framing and EPS insulation are non-porous, and resistant to mold and mildew. The result is greater thermal efficiency. In fact, the accel-E™ S.T.E.P. wall system is so thermally efficient, it exceeds ASHRAE 90.1 2007 and 2009 IECC requirements.

Construction Efficiency
By combining framing, cavity insulation and rigid foam insulation into a single installation process, the accel-E™ system can reduce labor costs by up to 50 percent over conventional framing.1 Panels are pre-cut to each project’s exact specifications and are available in heights up to 48 feet – and higher. Open cavities and pre-punched knockouts provide easy access for electrical and plumbing mechanical trades. And, because of the panels’ light weight, cranes and other specialized equipment are usually not needed.

The accel-E™ S.T.E.P. wall system offers exceptional flexibility, and is well-suited to a wide variety of design situations including structural, curtain walls and demising walls. Panels can be finished in virtually any exterior cladding material.

The Green Choice
Reduced jobsite waste and exceptional thermal efficiency are key aspects of the accel-E™ S.T.E.P. wall system’s green appeal. As a result of these and other factors, the accel-E™ panels can contribute points to as many as four LEED® categories – an increasingly important factor in both residential and commercial markets.

By reducing labor costs, enabling a shorter and simpler construction cycle, minimizing waste, and offering superior energy-efficiency, the accel-E™ S.T.E.P. wall system is an innovative and effective answer to many of the most critical challenges that will face the design and construction industries in the years to come.

The accel-E™ panels are manufactured by ACCELERATED Building Technologies, LLC - a company formed by two leading building materials manufacturers, combining the talent, resources and knowledge of Dietrich Metal Framing and NOVA Chemicals. ACCELERATED Building Technologies maintains ownership under SYNTHEON, Inc., a wholly-owned subsidiary of NOVA Chemicals, Inc., for the building and construction industry.
