Transform Your Project With IWS
A Simple 3-Step Process
Faster project completion, from formwork to finished façade.
1
Set the Form
Modular vinyl concrete formwork eliminates traditional formwork for openings and adapts to varying wall thicknesses.
2
Cast & Tilt
Windows are cast directly into the panel. The building envelope is immediately weathered-in after tilt.
3
Save Time & Cost
Save 3.5–4 average hours per opening. No lifts required — trades start months earlier.
“With escalating material and labor cost, traditional methods of construction should be reviewed. In searching for new techniques to improve my bottom line, IWS delivered just that. An overall 80% savings on labor along with a reduction in material cost. In total, this portion of the project was completed one week faster.”— Customer Review
