Is burning EPS toxic?
Test reports con­duct­ed by the Nation­al Research Coun­cil state: The max­i­mum tox­i­c­i­ty index obtained from the com­bus­tion of poly­styrene was of the same order as that of wood.” Fox Blocks ICFs have been test­ed to meet build­ing code require­ments for flame spread rat­ings, smoke devel­op­ment and tox­i­c­i­ty
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
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.
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.
Does EPS ‘off gas’?
EPS does not off-gas. Fox Blocks forms do not and nev­er have con­tained any CFC or HCFC prod­ucts. The forms are made by a steam process that uti­lizes pen­tene gas’ as a blow­ing agent. The blow­ing agent dis­si­pates from the prod­uct with­in 48 hours of man­u­fac­tur­ing. Fox Blocks forms are odor­less, do not dete­ri­o­rate, and do not off gas.
Do ICFs promote mold or mildew growth?
EPS is an inert, organ­ic mate­r­i­al. It pro­vides no nutri­tive val­ue to plants, ani­mals or micro-organ­isms. It will not rot and is high­ly resis­tant to mold and mildew.
Is an ICF home quieter than a stick framed home?
Absolute­ly. The exte­ri­or walls are two lay­ers of con­tin­u­ous insu­la­tion, the den­si­ty of sol­id con­crete and a lay­er of ½” gyp­sum board on the inside all con­tribute to supe­ri­or sound sup­pres­sion of STC 50 for the whole build­ing enve­lope. Note: A wood frame sys­tem of equiv­a­lent STC rat­ing would be 2 x 4 studs spaced 16˝ o/​c, with 3½˝ absorp­tive mate­r­i­al, 1 lay­er of 5 /8˝ Type X gyp­sum board on resilient chan­nels spaced 16˝ o/​c, and 2 lay­ers of 5 /8˝ Type X gyp­sum board on the oth­er side.

WOC 2011 - Great Kick Off
Trav­el­ing back to my home/​office in Atlanta from the recent World of Con­crete Show in Las Vegas, I was able to reflect on some of our company’s recent achieve­ments. The recent World of Con­crete show gave our com­pa­ny a plat­form or per­fect oppor­tu­ni­ty to…
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 form recyclable?
Yes, every com­po­nent of the Fox Blocks form itself plus the con­crete and rein­force­ment bars are recy­clable.
