Fox Blocks Insulated Concrete Forms (ICF)

Fox Blocks Insulated Concrete Forms (ICF) are the premier energy efficient building material. The foam forms are becoming popular as structurally superior to traditional wood framed buildings and provide greater wind and weather resistance in storm prone areas. As ICF buildings are made of concrete they provide excellent sound proofing and privacy from neighbors while maintaining and average  insulated R-value of 23 from its continuous insulation design .

  • Fox Blocks forms are fully reversible making making installation dummy proof
  • R-23, higher thermal value than traditional construction
  • Engineered internal ties allow for customization of rebar and wiring/utility placement
  • Mold resistant, Wind resistant, Fire resistant

ICF when complete produces durable concrete walls that last a lifetime and range in core wall thickness from 4 to 12 inches thick. Each product is interchangeable with other similar sized block forms.

Fox Blocks Core ICF Components

Straight block ICF form Fox Blocks

Straight Block

The  Straight Block is the most used ICF in the system, accounting for 80-85% of the entire project ICF material.
Each straight form measures 16" tall and 48" long  and is available in 4", 6", 8", 10", and 12" Core width wall sizes to accommodate your project needs. Fox Blocks are stacked and connected to enable a laser straight walls and together form a void where concrete is poured in. Each straight block is engineered with six high strength injection molded reinforcement braces that accept rebar block to block HV Clips, and any utilities to be placed on pre-pour. 

Each form is made from EPS polystyrene foam (Styrofoam) and can me be flipped upside down or horizontally to fit with other blocks making for easy install.  

90 Degree Corner Block

The 90 Degree Corner Block is 15-20% of the typical project.  Each unit includes 6 plastic injected Polypropylene (PP) ties that hold the EPS together and provide rigidity to the form. The Corner Block has the special patent pending corner bracket made to join the inner and outer form walls together and eliminate potential concrete "blow outs" from occurring during the pour. 

The Corners are available in 4", 6", 8", and 10" core width sizes.

T-block ICF Form Fox Blocks

T-Block 

T-Blocks are typically around 1-2% of ICF materials on an average residential or commercial build project and though they are not the most common form type they serve an important function. The T-Block is designed to provide additional reinforcement to areas where an interior wall intersects with and exterior wall. By added additional rigidity in these areas you can both reduce the amount of physical wall bracing required and eliminate concrete fill blow-outs. 

T-Block forms are available in 6" and 8" core width sizing.

45 Degree Corner Block

Corner 45' Blocks make up less than 5% of all ICF projects, but can be crucial in fabricating modern architectural design. The Fox Blocks system enables the builder to deliver on nearly anything the design team is able to throw out.

The Corner 45's are available in 6", 8", core width sizes.

Fox Buck

The Fox Buck product enables continious insulation of a home or building around cutout areas such as doors and windows. the 1" notches on each board allow concrete to fill inside the opening frame and enable greater defense against both moisture and draft penetration in these prone areas.
The Buck when implemented properly gives the builder and owner peace of mind that each building opening will maintain continuous insulation and maintain high insulation values. 

Fox Buck is available in 4", 6", 8", 10", and 12" core width sizes.

5 Reasons Why ICF Construction is Better than Wood

Jan 09, 2022 Jake Goodwin

ICF construction is excellent at insulating homes and reducing both acoustic noise and HVAC costs. ICF holds up against violent storms and natural disasters such as fires, earthquakes, and high winds. Structures that utilize ICF also last more than a lifetime. 

How do Insulated Concrete Forms Work?

Dec 04, 2021 Jake Goodwin

Commonly used in residential and commercial construction, insulated concrete forms (ICF) are permanent polystyrene blocks that are filled with concrete to create extremely durable and thermally efficient walls. Insulated concrete forms are what keep a home stable, durable, and warm, but how do they work, exactly?
