Can I leave Fox Blocks forms exposed to ultraviolet rays for an extended period (months)?
Yes, but you will notice a light dusting on the surface and a yellowing discoloration of the forms. This does not indicate any detrimental effects to the ICFs. We do suggest, that if the exterior finish is not going to be installed within around a 3 month period or more, the forms be protected from UV rays by installing a temporary building wrap type material. The powdery film must be removed with soap and water before the application of a synthetic stucco finish or waterproofing membrane.

Why Fox Blocks
What fasteners are recommended for ICFs?
Fox Blocks has conducted numerous fastener tests for pull-out strength and shear capacity for various fasteners – screws, ring shank nails and staples into the plastic webs. The recommendation for interior and exterior applications of finish materials is for the use of screws which provide the best holding capacity into the plastic webs or fastening strips in the forms which are identified on each block.
The EPS insulation does not provide any holding capacity for fasteners.
