The plas­tic webs in Fox Blocks forms are 100% recy­cled postin­dus­tri­al polypropy­lene. The EPS insu­la­tion is vir­gin mate­r­i­al. Recy­cled con­tent for an ICF block is mea­sured by weight. The recy­cled con­tent by weight of a stan­dard 6″ Fox Blocks form — 48%.

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.

Taper Top forms are specif­i­cal­ly designed to pro­vide a larg­er bear­ing sur­face along the top of the wall. Typ­i­cal­ly, the increased bear­ing sur­face may be used to sup­port mason­ry, floor or roof loads. Taper top forms are used in the tran­si­tion from ICF to wood frame con­struc­tion and the taper top form would be the top form on the wall.

The ICF blocks are held in place with either low expan­sion spray foam or a met­al starter track. The bracing/​alignment sys­tem, typ­i­cal­ly installed after the 4^th course of block, also sup­ports the ICFs in place. Once the con­crete is in the wall there is no con­cern with the forms mov­ing. The con­crete is con­nect­ed to the foot­ing with rein­forc­ing dow­els.
