Overview
Glass wool is the economical insulation for the building and HVAC side of the Lucknow market: duct insulation on hospital and hotel air-conditioning, over-ceiling thermal and acoustic blankets in offices and schools, and under-deck insulation on warehouse and factory roofs. Wedge Industries Limited supplies it in rolls, batts and slabs, plain or foil-faced, from regional stock.
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.

Installation and specification notes

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 to use in ceilings of hospitals and schools?
Yes. Glass wool is non-combustible (Class A1), inert and widely specified in healthcare and education buildings; foil or kraft-foil facings keep fibres contained.
Do you supply glass wool to Agra and Barabanki?
Yes. Orders for the whole Lucknow – Kanpur – Agra belt are consolidated for delivery; full-load orders can be dispatched directly to site.
Glass wool or rockwool for a PEB roof?
Glass wool is lighter and cheaper for roofs and ceilings below 450°C; rockwool is chosen where higher temperature, fire-rated assemblies or heavier acoustic mass is needed.
Can I get a rate contract for regular supply?
Yes. HVAC contractors and dealers in Lucknow and Kanpur can agree a monthly rate contract with fixed delivery days.
