ACCEL-E® S.T.E.P. wall system
A cost-effective and superior alternative to conventional framing, sheathing and insulation

Description
The ACCEL-E® Steel Thermal Efficient Panel (S.T.E.P.) is a thermally efficient, high performance building panel that exceeds the latest ASHRAE 90.1 2007 and IECC 2009 requirements. Strong, light in weight and energy efficient, it is composed of two time-tested materials - cold formed steel and expanded polystyrene (EPS) insulation - uniquely fused together to provide superior strength and thermal performance.

Uses
The ACCEL-E® S.T.E.P. wall system simplifies framing, cavity insulation and continuous rigid foam sheathing into one installation process, providing savings by reducing on-site labor costs, shortening construction cycles and improving energy efficiency.

Benefits

• Cost effective - Helps reduce onsite labor requirements and shortens construction cycles; results in faster installation, reduced construction defects and callbacks and lowered onsite waste and disposal costs
• Energy efficient - Contributes to lower heating and cooling costs
• Fire rated 1-hour assemblies available - Can be used in IBC Type I and Type II non-combustible construction
• Made from recycled materials and is itself 100% recyclable
• Resists mold, mildew and moisture
• May contribute toward LEED® project certification
• GREENGUARD certified

Composition & Materials
The ACCEL-E® wall panel is a 4' wide expanded polystyrene (EPS) panel with two embedded studs. The studs have a proprietary design and are formed in an "S" type cross-section comprised of three 1 5/8" flanges and two independent webs. EPS is fused through the outer web section to maximize structural and thermal performance. The inner web section, devoid of EPS, provides an open ACCEL-E® cavity to allow the use of additional light gauge metal or structural steel framing members, and enables the use of industry standard electrical and mechanical construction practices. The panels interlock at each side with a tongue-and-groove configuration molded into the EPS. No joint treatment is required to join adjacent panels. All steel used in the ACCEL-E® S.T.E.P. wall system is galvanized to
building industry standards to prevent rust.
