Comfortable Savings Strong Secure Responsible Main


There is an extraordinary level of comfort inside a PolySteel home. What makes a PolySteel home so dynamically different from any other?

Uniform Temperature
Cleaner Air

Protection from Mold and Termites


In a PolySteel wall, there is a balance created by the heat being emitted from your concrete wall and your body heat loss.  This balance creates a stabilizing effect on the interior environment, leaving you with an unequaled sense of comfort in summer or winter.

Another factor related to comfort is the temperature difference between the floor and ceiling.  In buildings constructed of conventional materials, the temperature difference between the floor and ceiling will range from 5 to 10 degrees Fahrenheit.  By comparison, the temperature difference from floor to ceiling in a PolySteel home is typically less than 2 degrees Fahrenheit.

The combination of concrete encapsulated within high density expanded polystyrene provides a superior barrier to the sounds and noises of the outside environment.  This creates a cocoon of peacefulness in which to live.

Finished with standard 1/2" drywall, PolySteel walls have a laboratory tested minimum Sound Class Rating of 48.

A reduction in reactions to respiratory allergies is another comfort factor in a PolySteel structure.  The effects of hay fever, asthma and other airborne allergies can be greatly alleviated as a direct result of the reduced leakage of outside air, which brings dust, pollens and other pollutants.  Tests have shown that the infiltration and leakage into a PolySteel building is one fourth (1/4) that of conventional walls.  In fact, the reduced air leakage of a PolySteel home, used in conjunction with properly installed fresh air exchangers and electrostatic air filters, can result in the best possible living environment available for respiratory allergy sufferers.

A feeling of physical security results from being sheltered by impenetrable steel-reinforced concrete walls, and the peace of mind that comes from knowing that you are living or working in the most energy efficient and environmentally favorable structure.

PolySteel walls are 2 to 4 times stronger than the maximum design wind load required by the Uniform Building Code. PolySteel walls are bullet resistant and have been independently tested to withstand flying debris driven by a 250 mph wind.

PolySteel walls are 4 to 9 times stronger than the maximum design earthquake load required by the Uniform Building Code.

PolySteel is the first insulating concrete wall system to pass the rigors of a 4-hour fire test without the addition of any wall coverings required to assist in its performance.  PolySteel's unique steel ties hold the EPS foam together, further insulating the walls and providing added protection on the side unexposed to the flame. PolySteel's extremely low toxicity, smoke development, and flame spread, make our walls safer from the hazards of fire.  The air tightness of PolySteel structures also inhibits the oxygen needed to allow a fire to spread rapidly.

You will appreciate that your new project is protected from the danger and destruction of mold and termites.

American PolySteel has licensed the patented termite-resistant technology, Perform Guard®, from AFM Corporation, becoming the only major insulating concrete form (ICF) block manufacturer in the industry to incorporate this technology into its product.

Perform Guard is the only code-recognized method that allows foam plastic insulation to be installed below grade in the heavily infested termite areas of the country.

Common Black Mold

Mold requires an organic material, such as wood on which to grow. PolySteel forms contain NO organic material.
Hollow cavities can trap moisture, making traditionally constructed structures vulnerable to mold. PolySteel walls are made of solid concrete and have NO cavities which trap moisture.

Properly ventilated PolySteel structures guarantee low humidity, greatly decreasing the opportunity for mold growth because mold requires a relative humidity of 50% or higher to grow.
