Overview
Rockwool insulation is the first product in the Wedge Industries Limited stock programme for the Lucknow region: it is bought on almost every plant maintenance visit, every HVAC duct job and every pre-engineered building. Slabs and wired mattresses insulate boilers, ducts, flues and steam lines; pipe sections fit hot-water and steam pipework; rolls and batts go into roofs, partitions and acoustic walls.
The material is inorganic stone wool — non-combustible to Class A1, dimensionally stable under thermal cycling and available with a hydrophobic treatment for outdoor and humid service. Sugar mills in Hardoi, food plants in Sandila and Barabanki, and MEP contractors on Lucknow hospital and hotel projects specify it for both heat retention and noise control.

Send the density, thickness and quantity for a delivered price to your site in Lucknow, Kanpur, Barabanki, Unnao, Hardoi or Agra. Bulk rates apply to full-vehicle loads.
Applications in Lucknow and the region
- Boiler, flue and steam-line insulation for sugar mills and process plants (Hardoi, Sitapur, Unnao)

Installation and specification notes
Use 100–150 kg/m³ slabs or wired mattress on hot surfaces above 250°C with cladding; 50–80 kg/m³ for ducts and roofs; foil-faced grades where a vapour barrier is needed. Pipe sections are ordered by pipe bore and wall thickness. Wedge can supply through the removable-jacket route where equipment must be opened for maintenance.

Frequently asked questions
What density of rockwool should I use for a boiler or steam line?
For hot surfaces above 250°C use 100–150 kg/m³ slabs or wired mattress under metal cladding; for HVAC ducts and roofs 50–80 kg/m³ is usual. Send the operating temperature and we will confirm the grade and thickness.
Do you deliver rockwool to Kanpur, Barabanki and Unnao?
Yes. Consolidated deliveries run to Lucknow, Kanpur, Unnao and Barabanki, and full-load orders are dispatched direct from the works to site anywhere in the belt including Agra and Hardoi.
Is rockwool fire rated?
Rockwool is non-combustible (Class A1). Fire-door and partition applications use the high-density HDRW 850 grade at 96 kg/m³ together with the tested board and seal system.
What is the difference between rockwool and glass wool?
Rockwool serves up to 700°C and is denser and better for hot industrial surfaces and fire-rated assemblies; glass wool serves up to 450°C, is lighter and is the economical choice for HVAC ducts, ceilings and roofs.
Can Wedge install the insulation?
Yes. Supervised application crews cover slab and mattress insulation, cladding and removable jackets across the Lucknow region on a supply-and-apply basis.
