The S4 Universal Lateral Flashing is a black aluminium finishing component designed for use within S4 roof-integrated solar PV mounting systems. It provides a secure, weatherproof seal along the sides of the photovoltaic (PV) array, helping to protect the installation from water ingress while delivering a clean and professional edge finish.
Manufactured from durable, weather-resistant aluminium with a sleek black finish, the flashing integrates seamlessly with all S4 in-roof frame types when used as a lateral sealing component. By sealing the outer edges of the array, it supports long-term durability, maintains system integrity, and enhances the overall visual appearance of the installation. Supplied in a 1290 mm length, it is designed for straightforward integration within the S4 mounting platform.
