1.  What is the R-Value of PolySteel?
Walls made of PolySteel perform, on an average, like a stick frame wall constructed for R-30 insulation.  But that's not the whole story.  The effective R-Value performance of PolySteel consists of three factors: (1) the R-Value of the expanded polystyrene, (2) the thermal stability of massive concrete walls reduces the temperature fluctuations, and, consequently, the heat load requirements, so common to stick-frame buildings. (3) air leakage (infiltration) can account for 20% to 40% of the heat load requirements of a stick-framed building.  PolySteel reduces this air infiltration by 75%!  As a result, with the combined performance of the R-Value of the expanded polystyrene, the stabilizing effects of the thermal mass of the concrete, and the reduced air infiltration, PolySteel walls actually perform as high as R-50, or more, in some areas of the country.  We even guarantee, in writing, that a homeowner will save at least 33% of their energy costs over 2 X 6 construction with R-19 insulation throughout the United States.

2.  How much does it cost to build with PolySteel?
The best way to answer this question is to compare building with PolySteel with the alternative construction you are considering.

  • A PolySteel home will cost, on average 2% to 4% more than building the exterior walls of a home with 2 X 6 frame construction.  If the alternative is 2 X 4 construction, the difference would be slightly higher.

  • A PolySteel basement will cost about the same, or even less, than a poured wall or concrete block basement that is insulated and finished with equivalent insulation.  If your alternative is a completely unfinished basement, PolySteel will cost a bit more.

  • A PolySteel home will cost about 5% to 6% more than building the home out of concrete block.

In comparing costs, it is important to remember that a PolySteel wall is far superior in strength, comfort, and energy efficiency than even the best insulated stick-framed or masonry wall.  In all cases, you will get more than you pay for in energy savings alone!

3.  What kind of footings are required for PolySteel walls?
Footings are generally determined by local building codes and specific soil conditions.  You may use a standard size footing for a PolySteel wall, however, if you build all the way to the roof, you might need to build your footing about two inches wider than the standard for your area.

We offer footing design tables to assist you or your builder in determining the proper sizing for your project.

4.  How high of a PolySteel wall can you pour at one time?
Generally speaking, you can pour one story at a time (8 to 10 feet).  Our recommended pour rate is four vertical feet per hour around the entire perimeter of the building.

PolySteel has been used for many multi-story residential and commercial applications, including a 7 and 9 story project in Missouri.

5.  How do I attach stucco, siding or brick to PolySteel walls?
PolySteel features recessed steel furring strips (attachment studs) every 12" on center. NEW PolyPro features composite studs every 6" on center with the largest attachment area in the industry. These attachment studs are designed to receive self-tapping screws for the attachment of stucco lath, brick ties, and/or siding.  PolySteel and PolyPro's attachment studs provide an excellent, uniform anchor for virtually any interior or exterior wall covering you desire.
