ICF, in construction, stands for Insulating Concrete Forms. It’s a building technique that uses hollow blocks made of insulating material, typically polystyrene foam, to create forms for concrete walls. Here’s a breakdown of ICF technology:

  • Components: ICFs are interlocking blocks that often resemble Lego bricks. They contain rigid insulation sandwiched between plastic webbing [1].
  • Process: These blocks are stacked together to form the desired wall shape. Concrete is then poured into the hollow core, creating a solid concrete wall with permanent insulation on both sides.
  • Benefits: ICF construction offers several advantages including superior energy efficiency due to the insulation, increased durability and strength compared to traditional wood framing, and improved soundproofing.

ICF construction is becoming more popular for both residential and commercial buildings as building codes become more stringent on energy efficiency and disaster resistance.
