The ACCEL-E® Steel Thermal Efficient Panel
(S.T.E.P.) Wall System

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 – and does it all in just 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 superior 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.

ACCEL-E® panels are manufactured with Plastbau® technology featuring the semi-continuous moulding of EPS into a wide range of innovative, top-quality products.

Plastbau technology enables SYNTHEON to engineer and offer revolutionary building components in a variety of heights, widths and densities (solid and hollow core). Plastbau technology processes also allow metallic reinforcements to be easily inserted in the EPS during the moulding cycle, creating unprecedented performance levels.
