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.
How does the ICF block get secured to the foundation?
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 4th 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.
Does the Fox Blocks contain recycled materials?
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%.
Is the Fox Blocks product rated by ‘Energy Star’?
Ener­gy Star does not eval­u­ate or rate insu­la­tion prod­ucts. Every Fox Blocks home when test­ed by an Ener­gy Rater, can meet and exceed the Ener­gy Star home stan­dards and achieve a 5 Star rat­ing and a HERS’ score well below the min­i­mum Ener­gy Star require­ment of 85, or in Cana­da, high­er than an Ener­Guide rat­ing of 80.
Is the Fox Blocks ICF product ‘LEED’ rated or certified?
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.
What is the difference between Fox Blocks ICFs and the competitors, and why are Fox Blocks ICFs better? Why should I use Fox Blocks ICFs?
Most ICF blocks share com­mon fea­tures and ben­e­fits. Fox Blocks, as a com­pa­ny, pro­vides 30 years’ expe­ri­ence in prod­uct devel­op­ment, doc­u­men­ta­tion, test­ing and train­ing, as well as ver­sa­til­i­ty in the line of prod­ucts to meet all appli­ca­tions. The key dif­fer­ence comes in the exper­tise and sup­port you get from Fox Blocks. Fox Blocks is the leader in insu­lat­ing con­crete form con­struc­tion – proven in over 100,000 com­mer­cial and res­i­den­tial projects across North Amer­i­ca. Exten­sive resources and sup­port sys­tems are avail­able to ensure your project’s suc­cess from start to fin­ish. Please vis­it our web­site www.Fox Blocks​.com to review our project gallery and find more detailed doc­u­men­ta­tion on the prod­ucts and the appli­ca­tions. Fox Blocks also pro­vides a toll free num­ber for Cus­tomer and Tech­ni­cal Sup­port 8773692562.
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.
How are Fox Blocks green/environmentally friendly?
Fox Blocks con­tain a min­i­mum of 40% recy­cled con­tent by weight.
  • Fox Blocks do not off-gas and are not man­u­fac­tured using any gas­es that deplete the ozone or are harm­ful to the envi­ron­ment.
  • Fox Blocks require low embod­ied ener­gy to man­u­fac­ture.
  • Fox Blocks do not con­tain any mate­ri­als, that pro­mote mold or mildew growth.
  • Fox Blocks are an effi­cient con­struc­tion method there­by reduc­ing the amount of con­struc­tion waste, dust and air pol­lu­tion in the build­ing process.
  • Build­ing with Fox Blocks will save on heat­ing and cool­ing costs because less air is exchanged between the out­side and inside of your home. This also means a small­er more effi­cient HVAC unit is required for the home.
  • Fox Blocks are sus­tain­able. They will not rot or dete­ri­o­rate for the life of your home.
  • Fox Blocks pro­vide a secure, durable, com­fort­able, long last­ing build­ing
How much will it cost per square foot to build an Fox Blocks ICF home?

Build­ing with Fox Blocks ICFs pro­vides you with a high per­for­mance wall sys­tem for the foun­da­tion and above grade walls. Build­ing any high per­for­mance home, with either ICFs or con­ven­tion­al wood fram­ing, has many fac­tors that define the end cap­i­tal costs.

What addi­tion­al mate­ri­als and labor are required to make a con­ven­tion­al foun­da­tion equiv­a­lent to an Fox Blocks ICF foun­da­tion which exceeds ener­gy code require­ments in most loca­tions? Con­ven­tion­al wood fram­ing requires con­sid­er­ably more mate­r­i­al, insu­la­tion and atten­tion to air seal­ing to make it qual­i­fy and per­form as a high per­for­mance wall. All of this, for con­ven­tion­al con­struc­tion, adds mate­r­i­al and labor costs to the over­all project. Fox Blocks ICFs pro­vide a sim­ple method to build high per­for­mance walls that pro­vide ongo­ing ben­e­fits from the high insu­la­tion val­ues and mass con­crete walls that are ener­gy-effi­cient and pro­vide cost sav­ings for the life cycle of the build­ing.

Com­par­ing cost per square foot between con­ven­tion­al con­struc­tion and ICFs for a high per­for­mance build­ing, is like com­par­ing apples to oranges. To devel­op con­struc­tion costs, more detailed infor­ma­tion is required, for instance the num­ber and size of open­ings, the shape and size of the home, the region­al costs for mate­r­i­al and labor, etc. If you have a project you’d like us to review and pro­vide a mate­r­i­al esti­mate, Fox Blocks would be hap­py to have one of our rep­re­sen­ta­tives con­tact you. Please com­plete and sub­mit a lead infor­ma­tion sheet on the web­site or call Cus­tomer Ser­vice.

Is the Fox Blocks form recyclable?
Yes, every com­po­nent of the Fox Blocks form itself plus the con­crete and rein­force­ment bars are recy­clable.
