Prod­ucts are not rat­ed or cer­ti­fied under the LEED pro­gram. The over­all build­ing is eval­u­at­ed and assigned a LEED rat­ing. In the selec­tion of build­ing mate­ri­als for a LEED design, Fox Blocks have many ben­e­fits that can enable, enhance or direct­ly con­tribute toward LEED points for the project.

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.

Yes, Fox Blocks has a brick ledge form and the xLer­a­tor ledge rein­force­ment that is designed to sup­port mason­ry. Fox blocks also has a tieKey acces­so­ry which is a specif­i­cal­ly made as a mason­ry tie, to be insert­ed through the form into the con­crete.

Fox Blocks offers the most com­pre­hen­sive installer train­ing in the indus­try. We can train your con­trac­tor or help you locate a trained installer in your area.

No. The char­ac­ter­is­tics of an ICF wall with the mass con­crete and the EPS insu­la­tion pro­vide the required vapor per­me­ance to meet build­ing code require­ments as a vapor bar­ri­er.

No. Spec­i­fi­ca­tions in the Amer­i­ca Con­crete Insti­tute (ACI) do not lim­it the max­i­mum dis­tance con­crete can free fall. Engi­neer­ing stud­ies and reports have shown that free fall from up to 35′ doesn’t reduce con­crete qual­i­ty and there is no evi­dence of seg­re­ga­tion or weak­ened con­crete strength. ICF con­crete design calls for a high slump mix which assists in reduc­ing seg­re­ga­tion.

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.

Yes, mar­gin­al­ly high­er on the ini­tial cap­i­tal costs, but, it is a record­ed fact that Fox Blocks high per­for­mance homes out per­form in com­fort and oper­at­ing costs over a wood framed home. These cre­ates month­ly cost sav­ings for the life cycle of the Fox Blocks home.

Fox Blocks rec­om­mends that all installers using Fox Blocks ICFs com­plete a Fox Blocks train­ing pro­gram to ensure they have a bet­ter under­stand­ing of the basics. How­ev­er, for first time installers, it is pre­ferred that a Fox Blocks trained, expe­ri­enced installer inspect the instal­la­tion pri­or to place­ment of con­crete and assist in the place­ment of the con­crete, as they are famil­iar with work­ing with con­crete and can ensure the build is struc­tural­ly sound and safe and the walls are con­sol­i­dat­ed prop­er­ly, built straight and plumb.
