Overview
Calcium silicate board is the largest industrial insulation line Wedge Industries Limited sells in Delhi NCR, and the Faridabad finishing works make the region its natural stock-and-cut market. Furnace and oven builders in Faridabad and Ballabgarh, boiler and process plants in Bhiwadi, Bawal and Manesar, and insulation contractors on Gurugram and Noida projects buy Wedge CalSil650LD boards cut to size, with high-density fire-rated grades for fire doors and shaft walls.
The board is rigid and self-supporting: it needs no wire mesh on flat surfaces, holds its thickness under cladding and does not slump on vertical boiler walls. It is inorganic, non-combustible and asbestos-free, manufactured to ASTM C533.

Standard sizes ship from Faridabad stock within 24–48 hours to Delhi, Gurugram, Noida, Ghaziabad, Sonipat and Bhiwadi; cut-to-size orders are scheduled by quantity.
Can you cut boards to my drawing?
Yes. Boards are cut and machined at the Faridabad works; send the drawing or a cutting list with the enquiry.
