Mike Lamb Posted October 19, 2019 Report Share Posted October 19, 2019 (edited) I know this insulation was used at least into the 1960s. It probably contains asbestos. Does anyone know the name? This building is from 1917 but I doubt it is that old. Edited October 19, 2019 by Mike Lamb Quote Link to comment Share on other sites More sharing options...
