StretchSeal Engineered Weather Barrier is a flexible butyl sub-seal that provides an exceptional watertight and vapour-tight barrier. Ideal for window sills, corners, and penetrations, it stretches and conforms effortlessly to irregular surfaces, maintaining a continuous barrier against water ingress at complex junctions. Its advanced self-healing properties around mechanical penetrations help ensure complete weathertightness, protecting vulnerable areas of the building envelope.
It adheres well to most building substrates and is formulated to remain flexible without hardening or cracking in cold conditions, ensuring reliable performance on site and long term durability in demanding Australian environments.
