Permavent LiteLead is a high strength butyl, self-adhesive aluminium flashing for use as a replacement for traditional lead sheet in all roofing and weatherproofing applications. LiteLead can be used in various roofing applications to provide weathertightness at junctions where lead was previously used such as step and apron flashings, solar panels, saddles at the top of valleys, parapets and around chimneys, dormers and other abutments.
