Description

The AT-50 aluminium sealing tape is a high-performance pressure-sensitive adhesive tape manufactured from dead-soft aluminium foil with an acrylic adhesive. It provides an instant, permanent seal on galvanised, stainless steel, and aluminium surfaces, and is widely used for sealing longitudinal and transverse duct joints, insulation lap seams, and vapour barriers. The foil conforms tightly to irregular surfaces and withstands temperatures up to 120 °C, making it suitable for both supply and return ductwork.
