iForms formwork walls assembled on site

The system

iForms

A building system based on ICF (insulated concrete forms) that replaces conventional masonry, doing away with bricks and blocks in favor of EPS forms.

A single element does what used to take several layers.

01

Less construction time

A building solution that significantly shortens schedules compared with conventional masonry.

02

Thermal and acoustic comfort

The insulation is built into the wall. It is not a layer added afterward; it is the EPS form itself.

03

High structural strength

The horizontal sections act as beams and the vertical sections as columns, with reinforcement according to the structural design.

04

Integrated services

Plumbing pipes and electrical services are integrated into the outer face of the forms.

Anatomy of the wall

How it is made up

iForms formwork block: EPS form with its interlocking teeth

EPS block with interlocking teeth. Concrete is poured inside it, and the form becomes part of the wall.

01

EPS form

Replaces bricks and blocks. It becomes part of the wall and provides thermal and acoustic insulation.

02

Concrete and reinforcement

Together they form the reinforced concrete vertically. The amount of reinforcement depends on the structural design of each building.

03

Horizontal beams

The 18 cm form creates a 14 × 10 cm beam; the 12 cm form, a 14 × 6 cm beam.

04

Vertical columns

The vertical sections act as columns. The 18 cm form creates a 10 × 6 cm column.

05

Services

Plumbing pipes and electrical services are integrated into the outer faces of the forms.

06

Finish

A flexible, water-repellent, high-strength finish. It accepts any type of cladding.
