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.

The EPS in an Fox Blocks has a flame retar­dant that allows the forms to be flame resis­tant. The EPS will melt when exposed to sus­tained tem­per­a­tures over 300°F (149°C). The igni­tion point of the melt­ed styrene is 600°F (315°C) (wood is approx­i­mate­ly 500°F (260°C). Fox Blocks have been test­ed to meet the build­ing code require­ments for flame spread and smoke devel­op­ment, plus Fox Blocks may be used as fire resis­tant rat­ed wall assem­blies in schools and hos­pi­tals.

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.

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.
