Overview
Rockwool is bought on almost every plant maintenance visit, HVAC duct job and pre-engineered building in NCR, and Wedge Industries Limited keeps the volume grades in stock at Faridabad for same or next-day delivery. Slabs and wired mattresses insulate boilers, ducts, flues and steam lines; pipe sections fit hot-water and steam pipework; rolls and batts go into PEB 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. Process plants in Bhiwadi and Sonipat, HVAC contractors on Gurugram and Noida towers, and PEB builders across NCR specify it for both heat retention and noise control.
