Overview
Ceramic fibre blanket is the working insulation of every furnace, heat-treatment shop and boiler in the Kanpur and Unnao industrial belt. Wedge Industries Limited supplies AlSi blankets from 1050°C to 1650°C classification in 64–192 kg/m³ densities, cut to length or as full 7600 × 610 mm rolls, together with boards, modules, paper, rope and tapes from the same fibre family.
Low heat storage means faster heat-up and cool-down cycles, and the blanket resists thermal shock and all furnace atmospheres. Standard and high-performance low-shot grades are available.

Ceramic fibre blanket price in Kanpur and Lucknow
Blanket is priced per roll or per kg by classification temperature, density and thickness — 1260°C × 128 kg/m³ × 25 mm is the volume grade. Send grade, thickness and roll quantity for a delivered price to Kanpur, Lucknow, Unnao, Barabanki, Hardoi or Agra; furnace contractors can request container-load rates.
Applications in Lucknow and the region
- Furnace and heat-treatment linings in Kanpur foundries, forging and engineering works
- Boiler backup insulation and manhole/door seals at sugar mills in Hardoi and Sitapur
- Kiln, dryer and oven insulation in ceramics, leather finishing (Unnao) and food plants
- Expansion joints, burner blocks and high-temperature gaskets
- Welding and hot-work protection blankets in fabrication shops
Installation and specification notes
Layered blanket linings are fixed with ceramic or alloy anchors; wrap linings on ducts and stacks are banded under cladding. Pair with calcium silicate or microporous backing to reduce shell temperature and with ceramic fibre board or modules where a rigid hot face is required.

Frequently asked questions
Which ceramic fibre grade should I use for a heat-treatment furnace?
1260°C classification at 128 kg/m³ is the standard furnace-lining blanket; for continuous hot-face service above 1200°C use 1430°C or 1650°C grades. Site engineering review is recommended above 1200°C.
Do you supply ceramic fibre board and modules as well as blanket?
Yes. Board, module, paper, rope, tape and felt are supplied from the same AlSi fibre family; see the ceramic fibre board page for Lucknow region supply.
Is ceramic fibre blanket available for Kanpur foundries from regional stock?
Yes. Proven sizes are held in regional stock and full rolls are dispatched from the works for larger relining jobs.
Can ceramic fibre be used on sugar-mill boilers?
Yes. It is used as backup insulation, door and manhole seals and expansion-joint packing on boilers, with calcium silicate for structural insulation of walls and headers.
What thicknesses are available?
13 mm, 25 mm and 50 mm in standard 7600 × 610 mm rolls; other thicknesses on request.
