Overview
The Aerogel Water Tank Insulation Cover (WedGel) from Wedge Industries Limited is a made-to-size insulation cover for water storage tanks, manufactured in silica aerogel blanket (wedgel). Thinnest cover in the range. Where there is no space for 50 mm of wool, aerogel does the job in 10 mm.
Aerogel is the premium option and it is specified for one reason: thickness. On a tank in a tight plant room, or where the cover must not change the tank’s footprint, it is the only material that fits.
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.

Construction
The cover is a three-layer laminate. A UV-resistant, waterproof, tear-resistant tarpaulin forms the outer skin. The Wedge Aerogel Sheet sits at the core. A smooth, moisture-resistant tarpaulin forms the inner face against the tank wall.
The wedge design advantage
Water in a tank stratifies — it is hotter at the top and cooler at the bottom, and heat loss is not uniform across the tank wall. A constant-thickness cover over-insulates one zone and under-insulates the other.
This cover is manufactured to a wedge profile: thicker insulation at the bottom where heat loss is higher, thinner at the top where it is lower. You pay for insulation where it does work, not where it does not.
Applications
- Space-constrained plant rooms
- Chilled and cryogenic water tanks
- Retrofit where cladding cannot be enlarged
- Marine and offshore water tanks
- High-value process tanks
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 Aerogel Water Tank Insulation Cover (WedGel) 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 Aerogel Water Tank Insulation Cover (WedGel) 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.
