How Does ECO-Block Work?

ECO-Block Insulating Concrete Forms (or ICFs) are expanded polystyrene [polly-STI-reen] panels that easily snap together to form walls. The space between the panels is filled with concrete that hardens into a monolithic, reinforced concrete wall of incredible strength.

The ECO-Block panels remain in place and allow for application of siding, sheetrock or any exterior or interior finishing material as well as adding insulation to the structure.

ECO-Block® Buildings Save Energy, Costs, and Natural Resources

ECO-Block® buildings consistently save 25-50% in monthly utility costs over the life span of the structure, translating into fewer resources consumed for the creation of energy. Beyond the insulating qualities of the foam block (R-22), the thermal mass of the concrete acts as an energy reservoir which helps maintain an even indoor temperature. Consequently, the HVAC system can be scaled down as much as 35%, offering additional cost savings.

An average 2,000 square foot home built with ECO-Block® can save up to 47 trees, which would have been cut for creating lumber.

What does all of this mean? Using ECO-Block for your next residential or commercial construction project will save you time and money and help you to build a more energy efficient building to save the occupant money for years to come!
