Wabo®WeatherSeal II joint seals are superior to silicone or urethane strip seals because it acts as a dual sealant. The impermeable closed cell foam backer is a weather-tight seal. Also, the silicone face serves as the primary seal and provides an aesthetic, colorized finish. When installed, Wabo®WeatherSeal II will expand depending on the temperature and time adapting to the width of the joint and the irregularities of the substrate. WS
