ICF — Insulated Concrete Forms
EPS formwork that stays in the wall — structure, insulation and lining substrate cast in one operation.
One System, Built to Work Together.
ICF stacks interlocking EPS forms like blocks, fills them with reinforced concrete, and simply leaves the forms in place — instant insulation on both faces of a monolithic wall.
The result is a fast, quiet, thermally exceptional shell: one trade builds the form, one pour makes the structure, and the finished wall is ready for boards and render.

Footing & Starter Bars
The foundation with reinforcement ready for the first course.
- 02
ICF Forms Stacked
Interlocking EPS forms build the wall like oversized blocks.
- 03
Reinforcement Placed
Bars set within the forms as the courses rise.
- 04
Concrete Core Poured
The structural core cast inside the insulated formwork.
- 05
Finishes Both Faces
Render outside, boards inside — straight onto the EPS.
01Form, Insulation, Substrate — One Product
The formwork never leaves; it becomes the wall's insulation and lining base.
02Exceptional Envelope
Continuous EPS on both faces wraps the concrete in insulation.
03Quiet Inside
Mass plus double insulation cuts noise through the wall.
04Fast, Simple Shell
Light forms stack quickly with small crews and no stripping.
