Q: Why use Insulated Concrete Forms?
A: Better construction efficiency, strength, safety, less moisture and mold, more air tight, better fire rating, quieter
Q: What are ICF Forms?
A: Insulated Concrete Forms are lightweight, interlocking foam blocks that remain in place as a functional part of the wall after the concrete is poured…strength, stability, and thermal mass result in an exceptionally superior wall system
Q: Can ICF’s be used above grade?
A: Absolutely. The many features and benefits which ICFs provide below grade make it perfect choice for above grade construction. In fact, to receive the full benefit from this type of quality construction and maximize the energy efficiency of the structure, ICF’s forms should be used for all exterior walls.
Q: Do the ICF forms stay in place after the concrete is poured?
A: Yes. The ICF forms are used to allow builders to pour a solid concrete wall. However, upon completion, the forms are designed to provide insulation, nailing surfaces, and a vapor barrier, all in one step.
Q: How are the utilities installed?
A. Directly into the foam. Once the concrete is poured and cured, channels or grooves are cut directly into the foam using an electric hot knife or router. Plumbing and electrical lines are then inserted into the groves and covered by drywall.
Q. Do you waterproof ICF walls?
A. As with any form of below grade construction, waterproofing is required. A non-petroleum based (latex) waterproofing material that can be either sprayed or rolled on. A solid adhesive membrane system also works well.
Q. How are doors and windows installed?
A. A wooden or vinyl buck Is built and incorporated into the ICF wall as it is being stacked prior to pouring the concrete. Once the concrete cures, the doors and windows are installed as usual.
Q. How much does it cost to build with ICF compared to other building materials?
A. Building with ICF is comparable in cost to building with 2X6 wall construction. In addition, the ICF wall will give you an effective insulation value of R50 – much greater than a 2X6 wall – allowing you to save 50-80% on your heating and cooling costs.
Q. How does ICF compare to concrete block or poured wall construction?
A. When cured, the concrete in ICF walls are 50% stronger and use 30% less concrete than traditionally poured walls. While the cost of a bare block or poured wall is less, ICF provides insulation and furring strips, and is ready to finish, making it a cost effective and less labor intensive choice.
Q. What products to you use for the exterior finish? And how do you install them?
A. You can use brick, stucco, wood, vinyl or metal siding. When installing brick, the use of the brick ledge form is used and it minimizes the use of brick ledge bracing. When installing stucco, it is applied directly to the form. The recessed fastening strips are clearly marked by raised beads to attach wood, vinyl or metal siding.
Q. What can be done to the interior side of the form?
A. The ties are within the forms provide a flat continuous attachment surface. The interior finishes can be installed directly to the furring strips with regular drywall screws.
Q. Can I visit an ICF job site or a completed ICF home?
A. Yes. Simply contact us and we will be happy to show you a project we have completed that is comparable to yours. |
