What is the R-value of Fox Blocks?

The clear R-Value of an Fox Blocks is R22, however current Energy codes recognize the lack of thermal bridging in an ICF and the contribution of the mass concrete on the influence of the thermal performance. Whole wall calculations indicate a Fox blocks wall assembly provides an R24 rating.

What are Fox Blocks used for?

Fox Blocks Insulated Concrete Forms are precision-manufactured, double-insulated forms for reinforced concrete walls. Using Fox Blocks results in: a strong, high-performance wall assembly.

What size are Fox Blocks?

1) Straight Blocks are 48″ in length. 2) All block have 2 5/8″ EPS for consistent R-Value. 3) Rebar spacing is consistently 16″ o/c and lower truss is 8″ o/c from top or bottom of upper truss.

Where are Fox Blocks made?

Fox Blocks now manufactures ICFs in 18 locations including Omaha, NE; Nazareth, PA; Becker, MN; Orlando, FL; Northbridge, MA; Post Falls, ID; Jerome, ID; McFarland, CA; Phoenix, AZ; Colorado Springs, CO; Cherryville, NC; Anchorage, AK; Keller, TX; Nixa, MO; Montreal, QC; Starbuck, MB; Ponoka, AB; Cap Pele, NB.

How thick are Fox block walls?

Fox Blocks makes straight and corner block insulated concrete forms (ICFs) in various widths, from 6 inches to 12 inches, fitting all foundation thickness needs, accommodating all wall heights, soil strengths, and siding materials.

How tall can you pour Fox Blocks?

The 6″ (150 mm) form, above grade, is limited to approximately 14′ (4. 2 m) in height. Walls higher than 14′ (4. 2 m) must use an 8″ (200 mm) or larger form.

How high can ICF walls be?

How tall can ICF walls be built? ICFs have been engineered and built to 48 feet tall (free standing/load bearing). It is important to note that in most applications, ICF projects can be designed using ACI 318 and are designed like any other steel reinforced concrete wall.
