Modified grade of EPS with a minimum density = 2.0 lb. per cubic ft.

EPS is very environmentally friendly when used as an insulated concrete form, providing excellent energy-efficiency and reducing the amount of wood used in building construction.

Class A Rating. The modified EPS rating that is used in the industry provides smoke which is less toxic than burning wood. Additionally, the modified grade of EPS that Blue Star uses, extinguishes when the flame source is removed.

Under ideal laboratory mold growth conditions, no fungi sample grew on the EPS during the 28 day incubation test period. EPS has no nutritional value, therefore is not a food source for organic bacteria or molds.

The 4 vertical posts per 4 ft. block @ 12” o.c. and 2 horizontal beam halves @ 12" o.c. which, when stacked, collectiverly create a form for an 8" diameter screen grid structure with vertical and horizontal post and beams on 1' centers.

Typically, for residential construction, #4 bar placed every other vertical on 2’ centers and #4 bar placed in every horizontal on 1’ centers, will meet all normal requirements. This equals approximately 7’ of rebar per block. Refer to Blue Star Insulated Concrete Forms Detailed Methods for specifics on rebar use.

A 6 bag (4000psi) ½” limestone aggregate mix, poured at a 6” slump, is what we consider ideal. The ICF industry and the International Code Council typically represent a 2500 psi mix with pea gravel aggregate (ICC requirements are based on 2500 psi concrete). We increase Portland content to both compensate for the 6 inch slump recommendation, which is necessary for flow ability, and the increased amount of Portland in and of itself, improves concrete flow and consolidation. We call for the ½” limestone aggregate because it makes for better concrete than a pea gravel mix. Much of the industry uses pea gravel because it is necessary for flow ability and consolidation due to the interruptions from cross members inherent in their design.

Note: If pea gravel is used, the suggested 6 bag mix is reduced to providing a 3000 psi concrete
