FOX BLOCKS JOINS THE ICF MANUFACTURERS ASSOCIATION
The ICF Manufacturers Association (ICFMA) is very pleased to welcome its newest Primary Member, Fox Blocks by Airlite Plastics.
Do I need an engineer to design and stamp Fox Blocks building plans?
Fox Blocks are listed in the building codes (IRC- Sections R404, R611 or NBCC Part 9) with specific applicability limits for residential construction. If the project meets the applicability limits within the building code, a Professional Engineer may not be required (dependent on local building department requirements). A building official has the right to request engineering and in some regions all projects require a professional’s stamp. For any projects that exceed the applicability limits, a Professional Engineer is required for the structural design. Check with your local building department.
Where can I purchase the product?
Fox Blocks has a wide-ranging network of knowledgeable product distributors and trained installers across North America; contact Fox Blocks Customer Service to find the closest Fox Blocks product distributor or trained installer in your area.
Is there a top and bottom on the blocks when installing the Fox Blocks forms?
Fox Blocks forms have a reversible interlock system on all blocks. The robust interlock allows the blocks to fit together very tightly, eliminating any requirement for adhesives. A reversible interlock speeds up the installation.
Are there different types of Expanded Polystyrene (EPS)?
EPS is listed basically under four property classifications – Type I, II, III and IV. The characteristics are based on the density of the molded foam which defines the product type. Fox Blocks ICFs are manufactured as a Type II EPS with a density of approximately 1.5 pounds per cubic foot.
Is EPS the same as XPS?
No, these insulation products are quite different. EPS is closed cell expanded polystyrene, while XPS is a closed cell extruded polystyrene. The properties, applications and costs of each are quite different. The majority of ICFs are manufactured with EPS.
What is EPS made from?
Polystyrene is virgin material, manufactured from petroleum. Polystyrene beads are expanded with steam heat to be up to 40 times their original volume and then the expanded beads are molded again by steam heat into 25⁄8″ rigid insulation panels to create a Fox Blocks ICF.
Can the plastic webs be detected by using stud finders?
A stud finder typically uses the density of materials to locate studs. The polypropylene (plastic) web material will show up on high quality density stud finders. Note, the webs in Fox Blocks are spaced at 8″ (200 mm) on center and will be continuous vertically on each side of the wall.
Does EPS absorb water?
No, EPS is a closed cell foam and does not act like a sponge or absorb water.
