Overview
Glass wool is the economical insulation for the building and HVAC side of the NCR market: duct insulation on hospital, hotel, mall and IT-park air-conditioning in Gurugram and Noida, over-ceiling thermal and acoustic blankets in offices and schools, and under-deck insulation on the warehouse roofs going up in Kundli, Bilaspur, Dadri and Greater Noida. Wedge Industries Limited supplies it in rolls, batts and slabs, plain or foil-faced, from Faridabad.
It is lightweight, so it reduces ceiling load, conforms easily to ducts and irregular surfaces, and its A1 non-combustible rating satisfies fire-consultant requirements for concealed ceiling spaces.

Frequently asked questions
Which glass wool density is used for HVAC duct insulation?
24 kg/m³ or 32 kg/m³ foil-faced rolls at 25 mm or 50 mm are the usual duct-wrap specification; higher-density slabs are used where the duct is exposed or acoustic performance is required.
Is glass wool safe in hospital and school ceilings?
Yes. Glass wool is non-combustible (Class A1), inert and widely specified in healthcare and education buildings; foil or kraft-foil facings contain the fibres.
What is the delivery time in NCR?
Standard rolls and slabs are delivered within 24–48 hours from Faridabad to Delhi, Gurugram, Noida, Ghaziabad and Sonipat.
Glass wool or rockwool for a PEB roof?
Glass wool is lighter and cheaper for under-deck roof insulation; rockwool is used where higher temperature, fire compartmentation or heavier acoustic mass is required.
Do you offer dealer or contractor rates?
Yes. HVAC contractors and dealers in NCR can set up monthly rate contracts with fixed delivery days.
