LOGIX Insulated Concrete Forms (ICF) are used to create solid concrete reinforced walls that are insulated for use, both above and below grade. ICF walls are particularly effective for residential or commercial buildings. Providing excellent insulation, thermal mass and structural strength. ICF walls offer a four hour fire resistance and a sound transmission class of STC-56.

LOGIX Insulated Concrete Forms (ICF) are based on the simple concept of modular interlocking blocks. These "blocks" or "forms" are made of expanded polystyrene panels held together with recycled polypropylene webs. The insulated concrete forms are dry stacked using a running bond and molded interlocks. Reinforcing steel is inserted in the wall cavity as required, then the forms are filled with concrete to create a monolithic insulated wall. The plastic webs used to hold the panels together also hold the reinforced steel in place prior to and during concrete placement. The webs also provide for attachment of interior and exterior wall finishes. Any wall finish that can be applied to a conventional framed building can be attached to a ICF wall. Because concrete starts out in liquid form there are no gaps or voids inside the wall to harbor mold or mildew, no outside air infiltration to bring dust, pollen and other allergens inside. With the continuous insulation on both sides of the reinforced concrete wall there is no thermal bridging, preventing energy loss.


With the standard 2.75" expanded polystyrene panel (thickest in the industry) the LOGIX ICF walls develop a true R-24 insulated envelope. If even more R-value is what you are after LOGIX offers the "Platinum" series form using BASF's patented "Neopor" bead. Tiny graphite particles give Neopor its platinum color. These infrared absorbers and heat reflectors reduce thermal conductivity. As a result the platinum series forms deliver a R-27 with our standard 2.75" panel. That's 15% more insulating value than any other ICF manufacturer can offer.

If even more insulating value is what you need, then LOGIX innovative "XRV" panels can be used to develop a thermal envelop rated at an astounding R-74. The "XRV" panels come in the standard 2.75" panels with available thicknesses of 4, 5, 6, 7 and 8 inches and can be used to build walls with concrete cores of 4, 6, 8, 10 and 12 inches. Only LOGIX offers choices of panel thickness, core thickness, foam type and web type. Logix Hybrid Technolog add insulating power and job site efficiency to large, complicated builds. With Hybrid Technology you can interchange solid and knockdown blocks. Thus solid blocks are used whenever possible and the knockdown blocks are used to build around complex pre-fabricated rebar cages.
