Murus

The company’s structural insulated panels use the chemical HFC 245fa as a blowing agent in their polyurethane SIPs. HFC 245fa has a zero Ozone Depletion Probability (ODP), a low Global Warming Potential relative to other refrigerants, and is not considered a VOC. The manufacturer claims the OSB is made from fast-growing, renewable softwood and hardwood species such as pine, poplar, and aspen from self-regenerating forests or plantation-grown trees. Murus’ OSB manufacturer is a member of the SFI (Sustainable Forestry Initiative). 800.626.8787. More
