ABSTRACT Many buildings suitable as bat roosts contain synthetic roofing materials, hereafter referred to as Non-Bitumen Coated Roofing Membranes (NBCRMs) – this includes Breathable Roofing Membranes (BRMs) and non-Permeable Roofing Membranes (nPRMs), rather than 1F felts. Building regulations require all construction materials to be fit for purpose, but some BRMs (although appropriate for their intended purpose) can potentially threaten the viability of existing, legally protected roosts because of the way bats physically interact with their surface. With the assistance of the Isle of Wight Bat Hospital and real-world observations of how bats physically interact with NBCRMs within a roof void, we present a new laboratory test method capable of reproducing the progressive disintegration of NBCRM surfaces due to the plucking effect of bat claws. The resistance to NBCRM disintegration was characterized using a modified laboratory fabric pilling box test method. The method reproduced the ‘fluffing’ effects and projections of loops of filaments on the surface of BRMs that have been observed within bat roosts. It was established that spunbond nonwoven BRMs, can be highly susceptible to surface disintegration. The newly developed method is intended to aid selection of NBCRMs that reduce the risk to bats in their roosts, promoting bat conservation.

用栖息蝙蝠评估建筑物屋面膜的钩住倾向的方法

摘要 许多适合用作蝙蝠栖息地的建筑物都包含合成屋顶材料，以下称为非沥青涂层屋顶膜 (NBCRM) - 这包括透气屋顶膜 (BRM) 和非渗透性屋顶膜 (nPRM)，而不是 1F 毡。建筑法规要求所有建筑材料都适合用途，但一些 BRM（尽管适合其预期用途）可能会威胁到现有的、受法律保护的栖息地的生存能力，因为蝙蝠与其表面的物理相互作用方式。在怀特岛蝙蝠医院的协助下，以及对蝙蝠如何与屋顶空隙内的 NBCRM 进行物理相互作用的真实世界观察，我们提出了一种新的实验室测试方法，该方法能够再现由于蝙蝠的拔毛效应而导致 NBCRM 表面逐渐崩解的情况。爪子。使用改进的实验室织物起球箱测试方法表征对 NBCRM 崩解的抗性。该方法再现了蝙蝠栖息地内观察到的 BRM 表面上细丝环的“起毛”效果和投影。已确定纺粘非织造 BRM 对表面崩解非常敏感。新开发的方法旨在帮助选择 NBCRM，以降低栖息地蝙蝠的风险，促进蝙蝠保护。对表面崩解非常敏感。新开发的方法旨在帮助选择 NBCRM，以降低栖息地蝙蝠的风险，促进蝙蝠保护。对表面崩解非常敏感。新开发的方法旨在帮助选择 NBCRM，以降低栖息地蝙蝠的风险，促进蝙蝠保护。
