There have been some reports of bats becoming entangled in membranes and damage to membranes caused by bats, but it is not understood how often either situation occurs, because there has been little scientific work on the issue. So a new collaborative, four-year research partnership between the School of Construction Management and Engineering at the University of Reading and the Bat Conservation Trust (BCT) sets out to provide a better understanding of the interactions between bats and breathable roof membranes. This project is also guided with the help of...
