About
IQ Weather Sealant is a premium neutral-cure silicone for durable, weatherproof sealing of glass curtain walls, doors, windows and construction joints. Its neutral, non-corrosive cure is safe on sensitive substrates such as glass, aluminium, coated metals and stone, and it stays permanently elastic — absorbing up to ±50% joint movement without cracking. With a service range from ‒40°C to +180°C, plus non-staining, UV-stable and low-VOC performance, it keeps joints watertight and clean season after season. Its quality is backed by independent SGS certification.
