Questions about



What are the differences between roofing foams, wall foams and sealant foams?

Polyurethane foams are either single- or plural-component products engineered on the molecular level for a specific purpose and application. Roofing foams tend to offer higher compressive strengths and smoother surfaces, while wall foams tend to offer faster reaction rates, higher yield and superior insulation R-values. Sealant foams can be similar in content to wall foams, and are either single-component or plural-component sealants in cans for smaller cracks and finer applications.


Are SPF roofs sustainable?

Yes. There are many factors that contribute to the sustainability of SPF roofing systems. First, no tear-off of the existing roof is required in 98% of re-roofing applications, which diverts thousands of tons of waste from landfill. Second, they are extremely durable, offering industry-leading resistance to severe weather including wind uplift and impact from airborne debris. Third, they offer an extremely long life expectancy of 20 years or more, and are renewable indefinitely with simple recoats. And fourth, they make a significant contribution to building energy efficiency. One Texas A&M study showed the university was able to pay for the cost of their new SPF roofs in 4.5 years though energy savings! And when they are combined with reflective coatings, SPF roofing systems also help combat urban heat island effect and reduce smog.


Is SPF roofing an affordable option for retrofits?

Yes, in fact, SPF roofing is the lowest cost re-roofing option in 98% of retrofit projects, because it can be applied to the existing substrate almost every time. That means reduced labor, and with tons of waste being diverted from landfill, disposal fees and the cost to the environment are both greatly reduced.


Is SPF roofing durable?

High-quality, well-installed ELASTOSPRAY® SPF roofing systems offer a 20-year life expectancy, and are renewable almost indefinitely with simple recoats. They also offer industry-leading resistance to wind uplift and severe hail, making them among the most durable systems available on the market.


Can SPF roofing reduce thermal bridging?

Because it is seamless and monolithic, SPF roofing provides a single layer of continuous insulation. Because it does not require fasteners, it helps reduce thermal bridging, which in turn improves energy efficiency.


Can SPF roofing help my project gain LEED® points?

ELASTOSPRAY®’s performance can contribute to many LEED® points, especially in the energy categories. In fact, we used ELASTOSPRAY on BASF’s new North American headquarters building, which achieved LEED double platinum!
