ICF Panel Introduction:

Insulating Concrete Forms (ICFs) are hollow blocks or panels made of EPS (expanded polystyrene) plastic foam that construction crews stack into the shape of the exterior walls of a residential (or commercial) building.
Workers then add reinforcing steel and fill the gap (typically 4” to 8”) between the two layers of foam with concrete, which cures and hardens into a monolithic core. The foam panel stays in place and acts as insulation for the home. This combination of concrete, steel and foam creates an incredibly strong and energy-efficient structure.
The EPS forms are held together with clips that are later used to attach sheetrock (inside) and siding (outside).Because there is no wood on the exterior walls of the home, they become impervious to decay, and mold. In addition, the finished thickness of approximately 11” of concrete and EPS provides an extremely high level of insulation from both weather and noise. Due to the inherent nature of the walls, ICF homes are exceptionally energy efficient, interior air quality of the home is greatly improved, and the home will have a high resistance to wind and/or earthquake damage

ICF Panel Introduction:

structural strength
vapour barrier
sound barrier
surface for installing drywall and exterior siding ...all in one

The construction industry is evolving with the growing use of Insulated Concrete Forms (ICFs).
ICFs are hollow, lightweight, "stay in place" forms made of 2 panels that are connected by polypropylene webs.
The insulated concrete forms are modular units that are dry-stacked (without mortar) and filled with concrete. The insulated concrete forms lock are put together and serve to create a form for the structural walls of a building. Concrete is filled into the cavity to form the structural element of the walls. The reinforcing steel (rebar) is added before concrete placement to give the resulting walls flexural strength, similar to bridges and high-rise buildings made of concrete.

After the concrete has cured, or firmed up, the insulated concrete forms are left in place permanently in order to achieve a 5 in 1 building solution that provides:

  • structural strength
  • insulation
  • vapour barrier
  • sound barrier
  • surface for installing drywall and exterior siding ...all in one step!

The four types of ICfs that we produce have the following dimensions of the concrete core:

  • 15.24 cm (with 6.35cm of insulation on both sides)
  • 20.32 cm (with 6.35cm of insulation on both sides)
  • 20.32 cm FOR PASSIVE HOUSES (with 18cm of insulation on the external side and 6.35cm on the internal side)
  • 25.4 cm (with 6.35cm of insulation on both sides)

As concrete cures it becomes stronger; ICFs guarantee your home becomes stronger every day.


ICF can be used both below and above grade for single and multi-storey residential, commercial, institutional and industrial construction.


Reduces construction time and labor costs
5 in 1 system incorporates structure, insulation, vapor barrier, sound barrier, and studding
the construction time is reduced this means that the costs are smaller
Offers more cost savings
50-80% in monthly savings on energy bills.
Less repair and maintenance over time.
Provides superior comfort
Reduces sound transmission by two thirds with an STC rating of 50+.
EPS stops air movement and creates an airtight seal around the structure.
Prevents the entry of dust, pollens and pollution.
Protects the environment
Reduces harmful emissions by 30-50%.
Eliminates the use of wood which reduces deforestation.
Ensures maximum safety
Walls have a fire rating of 3+ hours.
Reinforced concrete provides resistance to high winds and storms.
