    Insulated Concrete Forms (ICFs)

The Latest in ICF Technology and Design -
Manufactured to Lower Labor and Accessory Costs

Energy efficient: The combination of insulation and the concrete core acts as a mass wall and blocks air infiltration, allowing buildings to save significantly on their heating and cooling costs

Flexible: ICFs are a lightweight rigid foam insulation block. Walls can be designed tall, short, of varying thicknesses and with any curve or shape

Fast build - lower cost: You don't need additional air or vapor barriers or external insulation; and the stay-in-place insulation lets you place concrete in cold weather without additional heating or curing

Superior Structures: Structures build with ICFs are up to 25% stronger than other concrete walls, helping withstand earthquakes, hurricanes and tornadoes

Green: ICF products are made with recycled materials and can contribute LEED credits. They improve indoor air quality and emit no volatile organic compounds (VOCs)

A reduced construction schedule will move you into your more energy efficient building even sooner.

Fox Blocks, the leading manufacturer of ICFs, provides you with the most efficient and profitable building envelope available. Fox Blocks ICF buildings are energy-efficient, environmentally-friendly, sustainable, quiet and comfortable and give you superior results when compared to conventional building methods. An envelope that resists harmful mold, dust and allergens, along with powerful wind, storm and fire damage.

Fox Blocks - Straight Block

The Straight Block typically makes up 85% of the ICF wall assembly on most residential & commercial jobs.

This block has six (6) strong full length injection molded plastic ties made from Polypropylene (PP) regrind resin that are well marked with the word "Fox Blocks" located on both sides of the block. These ties secure the two pieces of 1.5 pcf density modified Expanded Polystyrene (EPS) foam together that makes up each block type. The blocks are stacked tightly together and inter-locked end to end to the desired wall length.

Once a single layer or course of ICF blocks is installed, horizontal reinforcing steel bars are inter-locked securely together in the ties of the blocks, then another course of Straight Blocks are placed firmly on top as the wall is built.

To improve construction wall strength during installation, each course of blocks should have their end-joint connections staggered in a running bond method from the course adjacent to it. This installation method is typical for all Fox Blocks ICF form types and sizes.
