Using the most innovative raw materials balanced with care for the environment, XLS 2000 has been specially formulated for high performance using an HFO blowing agent. Products made with HFO blowing agents have a low Global Warming Potential and are a better choice for the environment. Many countries now require spray foam insulation to be manufactured with HFO blowing agents. In the United States, several states have already moved in this direction. Many closed-cell alternatives have Global Warming Potentials ranging from 700-1400. By selecting XCELUS XLS 2000, with a Global Warming Potential of 1, you are contributing to the reduction of greenhouse gas emissions.
