Foam is available in all kinds of different formulations. You may be thinking of the foam cushions in your couch or the foam that is used to make a picnic cooler. Polyurethane foam is formed when two chemicals are mixed together. It expands and quickly cures into a rigid foam product. Bags of foam mix are available for a lightweight product to use instead of concrete to hold posts upright in a hole. You can use it to set a mailbox or fence post. Foam can also be sprayed to expand into a thick, insulative and protective roof coating that seals cracks and fissures in a flat roof surface. But, how tough is sprayed polyurethane foam (SPF)?
Polyurethane Foam Used to Seal Mine Shafts in Arizona
The bagged type of polyurethane foam is used to make slabs that are formed in the field to plug old copper mine shafts in the Saguaro National Park East. The workers use bagged foam chemicals that are separated from mixing. When the bag is activated by letting the chemicals mix together, polyurethane foam expands into a single piece. It cures quickly, and it is shaped with hand tools to fit the mine shaft after it cures. More foam is added to the top, then dirt is filled in on top of that. The polyurethane foam plug used to seal mine shafts is said to be able to withstand the weight of a large truck.
Longevity of Spray Polyurethane Foam Roofing
An article posted at the San Francisco Chronicle’s website notes that a “good-quality SPF roof could last 50 years or longer.” Spray foam roofing with a maintained elastomeric top coat stays watertight, provides excellent thermal insulation, and resists damage from ultraviolet light even in the blistering hot Phoenix, Arizona sunshine. Plus, SPF roofing is lightweight to reduce tons of roof stress when renovating a rubber and gravel flat roof design.
With polyurethane being used to permanently seal mine shafts, it is more than tough enough for your commercial flat roof in Arizona. In addition to its integrity and longevity, SPF roofing provides excellent thermal insulation to reduce your energy costs for keeping commercial spaces cool during hot Arizona summers. Foam Experts Roofing Inc has taken an extra step in providing the best foam roofs by developing the Max-X Foam Gun to ensure a top-quality professional SPF roof application every time.
