Welcome

Welcome to the bats and breathable roofing membranes website. It is aimed that you will find information here regarding the issues surrounding the use of modern roofing underlays in bat roosts. 


My research is centred around the question 'what constitutes a bat friendly breathable roofing membrane?'. The project was set up following reports of bats becoming entangled in fibres that had been pulled loose from breathable roofing membranes (BRMs), since then further concerns over microclimate and membrane longevity have been raised. Whilst there is currently no answer to this question, it is hoped this project will help develop clear guidleines for the use of  BRMs in bat roosts.
