Overview
Where a furnace needs a rigid hot face, a self-supporting back-up layer or a fast relining, ceramic fibre board and modules replace brick and castable at a fraction of the weight. Wedge Industries Limited supplies vacuum-formed AlSi boards, folded blanket modules, ceramic fibre paper and rope to foundries, forge shops, heat-treatment plants and ceramic kilns in the Kanpur – Lucknow – Unnao belt.
Boards are machinable and cut to drawing at the works; modules are anchor-fixed straight to the furnace shell, cutting relining time from days to hours.

Ceramic fibre board price
Boards are priced per sheet by grade, thickness and size; modules per piece by size and anchor type; paper per roll. Send the furnace drawing or a list of sizes for a delivered price to Kanpur, Lucknow, Unnao or Barabanki.
Applications in Lucknow and the region
- Hot-face linings and back-up boards in induction, forge and heat-treatment furnaces (Kanpur)
- Kiln cars, burner blocks and door linings in ceramics and glass plants
- Boiler peep-hole, manhole and expansion-joint gaskets with ceramic fibre paper and rope
- Aluminium and non-ferrous launder and ladle linings
- Fireplace, oven and dryer insulation for food and hospitality projects in Lucknow
Installation and specification notes
Boards are fixed with studs and washers or cemented; modules are fixed to the shell with welded studs and the joints compressed. Use blanket as a back-up layer and calcium silicate or microporous to reduce shell temperature. Wedge cuts boards and supplies anchors with the order.

Frequently asked questions
When should I use ceramic fibre board instead of blanket?
Use board where a rigid, self-supporting or machinable hot face is needed — doors, burner blocks, kiln cars, back-up under brick. Blanket is used for wrap, layered and flexible applications.
What are ceramic fibre modules?
Folded blanket blocks with built-in anchors that fix directly to the furnace shell; they give a fast, jointless lining and are the usual choice for relining furnaces in Kanpur foundries.
Do you supply ceramic fibre paper and rope?
Yes — paper in 2, 3 and 5 mm at 160–240 kg/m³, plus rope, tape and cloth for gaskets and seals.
Can boards be cut to drawing?
Yes. Boards are machined to drawing at the Faridabad works and shipped with the anchors and blanket for the job.
Which classification temperature do I need?
Match the classification temperature to the hot-face operating temperature with margin: 1260°C for most heat treatment, 1430°C or 1650°C for forge and melting furnaces. Engineering review is recommended above 1200°C.
