BASF's closed-cell spray polyurethane foam (SPF) roofing systems deliver longer life expectancy and lower lifecycle costs over traditional systems. We provide building owners and facility managers with a roof owners' manual and a step-by-step roof inspection checklist. SPF roofing systems offer excellent retrofit applications to existing roofs by reducing in most cases the need to tear off much of the existing roof. BASF's roofing SPF is very lightweight and has an insulating R-value of 6.3/inch. To learn more about our SPF roofing and building envelope SPF systems, please select any of the icons above.
