ULTRA-THANE 230 HFO FM ROOFING is a closed-cell, two-component, spray-inplace, rigid monolithic, exterior spray, polyurethane foam that bonds to traditional roof substrates. Ultra-Thane 230 HFO Roofing Foam creates a seamless waterproof barrier which can be installed in additional thickness to create a positive slope to drain on flat roofs.

Ultra-Thane 230 HFO Roofing Foam is a fluid applied, fully adhered membrane, providing superior performance in minimizing heat transfer, condensation and air leakage. Ultra-Thane 230 HFO Roofing Foam is based on Low GWP hydrofluro-olefin (HFO) Technology to expand the polyurethane polymer into a cellular insulation.

Ultra-Thane 230 HFO Roofing Foam has FM approval over four assemblies with Ultra-Flex 1000 STD, Ultra-Flex 1000 HT STD, Ultra-Guard 5700 CA, and Ultra-Tuff 2800 STD coating systems.
