Ultra-lightweight Foamed Glass Aggregate ( UL-FGA ) is a lightweight fill alternative that is used on infrastructure , commercial , and residential projects . Beneficial properties of UL-FGA include a low unit weight (< 15 pcf dry density ), good insulating value , high friction angle , non-reactive and non-leaching behavior , volume stability , and porosity . Additionally , the material is made from 100 % recycled glass and has an attractive carbon and energy footprint compared to other lightweight fill options . This presentation will cover the physical and engineering properties of UL-FGA , application areas , design considerations , sustainability and ISI Envision considerations , and greater-New England case studies from projects that have utilized UL-FGA in design and construction .
