DSM issues life cycle assessment for composite windows

DSM and Fiberline Composites have worked together to develop window solutions based on thin, high strength pultruded composite profiles. Because of their high stiffness and strength, these profiles enable the effective glass surface of the window to be increased. Composites are also good heat insulators, helping to reduce the energy bill of home owners.

DSM and Fiberline used the life cycle assessment (LCA) methodology to identify the material, energy and waste flows associated with the production of window products. The environmental impact or eco-footprint helps to substantiate the positive contributions composites can bring to sustainability, in this case over windows made in aluminum.

“DSM has in-house expertise and a solid track record in performing LCAs”, says Robert Puyenbroek, Chief Technical Officer of DSM Composite Resins. “We are committed to lead the composites industry in implementing LCAs as a key decision making tool for innovation and development processes. Consequently, DSM is actively involved in the development of international standards and guidelines for life cycle assessment.”
