Please noteThe underlay can be used to provide temporary weather protection. However, an exposed underlay will be subjected to UV light which may lead to premature failure. Therefore, the exposure period should be kept to a minimum. An underlay is not a total waterproof barrier and if used as a temporary waterproof covering, some rain penetration may occur. In certain conditions, particularly if there is persistent heavy rainfall combined with subsequent severe freeze/thaw conditions, an underlay should not be exposed for more than a few days. (BBA)
