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

Description
Constructed of cold-formed steel and expanded polystyrene (EPS), the accel™ Steel Thermal Efficient Panel (S.T.E.P.) wall system combines strength and performance with superior insulation. The result is a thermally efficient, high performance building panel that is strong, lightweight, energy efficient and economical.

Uses
The accel™-E S.T.E.P. wall system simplifies the framing, insulation and sheathing installation process and is also ideal for demising walls and curtain wall applications.

Benefits

• Cost effective - Helps reduce onsite labor requirements and shortens construction cycles; resulting in faster installation, reduced construction defects and callbacks and lowered onsite waste and disposal costs
• Energy efficient - Contributes to lower heating and cooling costs
• Class A fire-resistance rated- Can be used in non-combustible construction.
• Fire rated – 1-hour assemblies available.
• Made from recycled materials -100% recyclable - Can contribute points for LEED certification
• Resists mold, mildew, moisture, termites, other insects and rodents.

Composition & Materials
The accel-E™ wall panel is a 4' (1.2 m) wide expandable polystyrene (EPS) panel with two proprietary studs that are fabricated using UltraSTEEL technology. The studs are formed in an “S” type cross-section that is comprised of three 1 5/8" (41.3 mm) flanges and two independent webs. EPS is fused through the outer section to maximize structural and thermal perfomance. The inner section, devoid of EPS, provides an open 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.

Types
Available in the following types:

• Exterior stud flange flush with foam
• Exterior stud flange embedded in foam

Sizes

• Standard widths of 4' (1.2 m)
• Custom heights limited only by the mode of transport required for delivery
• Overall panel thicknesses of 5 1/2", 6", and 8" (140, 152, 184 and 203 mm)
• Weight for 8" thick panel – approximately 40 lb (18 kg) based on a 4' x 8' (1.2 x 2.4 m) panel
• Weight for 5 1/2" thick panel – approximately 30 lb (14 kg) based on a 4' x 8' (1.2 x 2.4 m) panel.
