FOX BLOCKS JOINS THE ICF MANUFACTURERS ASSOCIATION
The ICF Man­u­fac­tur­ers Asso­ci­a­tion (ICF­MA) is very pleased to wel­come its newest Pri­ma­ry Mem­ber, Fox Blocks by Air­lite Plas­tics.
Do I need an engineer to design and stamp Fox Blocks building plans?
Fox Blocks are list­ed in the build­ing codes (IRC- Sec­tions R404, R611 or NBCC Part 9) with spe­cif­ic applic­a­bil­i­ty lim­its for res­i­den­tial con­struc­tion. If the project meets the applic­a­bil­i­ty lim­its with­in the build­ing code, a Pro­fes­sion­al Engi­neer may not be required (depen­dent on local build­ing depart­ment require­ments). A build­ing offi­cial has the right to request engi­neer­ing and in some regions all projects require a professional’s stamp. For any projects that exceed the applic­a­bil­i­ty lim­its, a Pro­fes­sion­al Engi­neer is required for the struc­tur­al design. Check with your local build­ing depart­ment.
Where can I purchase the product?
Fox Blocks has a wide-rang­ing net­work of knowl­edge­able prod­uct dis­trib­u­tors and trained installers across North Amer­i­ca; con­tact Fox Blocks Cus­tomer Ser­vice to find the clos­est Fox Blocks prod­uct dis­trib­u­tor or trained installer in your area.
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.
Are there different types of Expanded Polystyrene (EPS)?
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.
Is EPS the same as XPS?
No, these insu­la­tion prod­ucts are quite dif­fer­ent. EPS is closed cell expand­ed poly­styrene, while XPS is a closed cell extrud­ed poly­styrene. The prop­er­ties, appli­ca­tions and costs of each are quite dif­fer­ent. The major­i­ty of ICFs are man­u­fac­tured with EPS.
What is EPS made from?
Poly­styrene is vir­gin mate­r­i­al, man­u­fac­tured from petro­le­um. Poly­styrene beads are expand­ed with steam heat to be up to 40 times their orig­i­nal vol­ume and then the expand­ed beads are mold­ed again by steam heat into 258″ rigid insu­la­tion pan­els to cre­ate a Fox Blocks ICF.
Can the plastic webs be detected by using stud finders?

A stud find­er typ­i­cal­ly uses the den­si­ty of mate­ri­als to locate studs. The polypropy­lene (plas­tic) web mate­r­i­al will show up on high qual­i­ty den­si­ty stud find­ers. Note, the webs in Fox Blocks are spaced at 8″ (200 mm) on cen­ter and will be con­tin­u­ous ver­ti­cal­ly on each side of the wall.

Does EPS absorb water?
No, EPS is a closed cell foam and does not act like a sponge or absorb water.
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.
