WebbSpray foam lifts shouldn’t be thicker than 2” each time and should be allowed to cool before another lift is applied - but sometimes, to achieve 6” thickness, operators apply two 3” lifts and in quick succession. This generates massive amounts of heat and increases the likelihood of cracks. Gregg has a great video investigating such a problem here: WebbFor polyurethane (PUR) and polyisocyanurate (PIR) foam insulation systems, our high-performance surfactants boost energy efficiency. Typical applications include: Foam core laminate Pour-in-place insulation Spray insulation polyol blends
