Product Description

Lancaster Cold Water Tank Jackets are high-performance insulation solutions designed to protect cold water storage tanks from heat loss, frost damage, and condensation.

Each jacket is supplied as a two-piece set: a flexible wraparound side section and a separate lid panel. Both sections are constructed from a non-combustible, lightly-bonded glass fibre blanket core, fully enclosed in a seam-welded plastic outer cover for durability and moisture resistance. The lid incorporates a lightweight plastic stiffener to prevent sagging.

Installation is quick and secure using the provided fixing tapes, ensuring a snug fit. These jackets meet the requirements of Water Byelaw 30 and BS 7181:1989 and are highly resistant to vermin and the effects of condensation.
