Overview
A ceramic fibre tank insulation cover is specified for vessels operating far above normal water temperature. The Ceramic Fibre (AlSi) High-Temperature Tank Insulation Cover from Wedge Industries Limited is a made-to-size insulation cover for water storage tanks, manufactured in alumino-silicate ceramic fibre blanket (alsi). For tanks and vessels operating far above water temperature — process vessels, deaerators, hot condensate.
This is not a domestic water tank product. Specify it where the vessel runs hot enough that a foam or a wool would degrade — AlSi 1260 is classified to 1260 °C.
An uninsulated water tank loses heat in winter, gains it in summer and sweats with condensation in between. On a rooftop tank in India, an uncovered tank can leave stored water uncomfortably hot through the afternoon and cold by dawn. A correctly specified cover holds the tank’s temperature and stops surface condensation from dripping onto the structure below.

Applications
- Deaerator and hot condensate tanks
- Process vessels above 450 °C
- Steam drums and boiler ancillaries
- Refinery and petrochemical vessels
- Foundry and steel plant water systems
Installation
Every cover is manufactured to your tank’s dimensions — supply the diameter and height, or the tank model, and we cut to match. Covers are supplied with the fixing system appropriate to the material: adhesive and foil tape, banding straps, or Velcro and buckle closures on removable jackets.
Surfaces should be clean and dry before fitting. Seams are sealed with matching foil tape so the vapour barrier is continuous — an unsealed seam on a cold water tank will condense internally and defeat the cover. A full application guide is issued with every order.

Frequently asked questions
How is the Ceramic Fibre (AlSi) High-Temperature Tank Insulation Cover priced?
Pricing is on request. Water tank covers are made to size, so the rate depends on tank diameter, height, thickness and facing. Send us your tank dimensions and we return a firm quotation within 24 hours.
What tank sizes do you cover?
Every cover is cut to your tank. Send the diameter and height (or the tank model, e.g. Sintex 1000 L) and we produce the cover to match. Non-cylindrical and RCC tanks are covered too.
Can the Ceramic Fibre (AlSi) High-Temperature Tank Insulation Cover be used outdoors?
Yes — outdoor covers are supplied with a UV-stable facing or cladding. Tell us the tank is rooftop or external and we specify the facing accordingly.
Do you export?
Yes. Wedge Industries Limited manufactures in India, the UK, Spain and China and exports to 45+ countries, with regular shipments to the UAE, Saudi Arabia, Qatar, Kuwait and the wider Gulf.
Can I get a technical data sheet?
Yes — request the TDS with your quotation and we send the full specification, test standards and installation guide.
