Simon Baker and Doug Brady of Hunstman Building Solutions (HBS) discuss the recent global supply chain issues that have had a significant impact on the availability of various building materials, including ISO. Combined with the fact that residential housing starts are at their highest since before the crash in 2007, what does all this mean for contractors and builders that rely on these materials every day? In addition to material shortages, Simon and Doug talk about updated building codes, ever-evolving foam technologies, and how that will drive increasing demand for spray foam down the road.
