GPG Outbrief 26: Lightweight Secondary Windows

Compared to window replacements, secondary windows are a cost-effective and efficient way to improve thermal performance and occupant comfort and reduce noise. These lightweight secondary windows are manufactured with the same thin glass as the recently evaluated quad-pane windows. They are easy to install and suitable for structures that cannot handle extra weight. During the webinar, researchers and facility managers discuss findings from the project evaluation, share operational guidance and answer questions.
