Overview
Spray foam is the fastest way to insulate a large existing roof or shed: the crew sprays a seamless closed-cell layer onto the underside of the sheet or over the slab, sealing joints and stopping condensation drip at the same time. Wedge Industries Limited applies it with its own certified crews from Delhi NCR and through qualified partners in Uttar Pradesh, and supplies chemical drum sets to local applicators.
In the Lucknow region the demand is warehouses and PEB sheds in Kanpur and Barabanki, poultry and dairy sheds, cold-store retrofits in the potato belt, and metal roofs on factories and institutions that overheat in summer. R.C. Chemical Industries in Lucknow has already bought PUF from Wedge.

Applications in Lucknow and the region
- Under-deck insulation of PEB warehouses and factory sheds in Kanpur, Barabanki and Unnao
- Cold-store, ripening-chamber and ante-room retrofits in the Hardoi–Kanpur–Agra potato belt
- Poultry, dairy and mushroom sheds needing condensation control

Installation and specification notes
The surface is cleaned and primed where needed, the foam sprayed in passes to the specified thickness, and a UV-protective coating applied on exposed surfaces. A site survey fixes the substrate condition, access and mobilisation; work is scheduled by roof area in one mobilisation.

Frequently asked questions
What does spray foam insulation cost in Lucknow?
Indicative applied rates are ₹970–1,025/m² for 50 mm, ₹1,420–1,500/m² for 80 mm and ₹1,720–1,820/m² for 100 mm, ex-GST, confirmed after a site survey; mobilisation is quoted with the job.
What is the minimum job size?
200 m². Smaller areas can be combined with a neighbouring site or served with board insulation instead.
Is spray foam suitable for a cold store?
Yes. Closed-cell foam at 80–100 mm is used to retrofit cold-store walls and ceilings and to seal panel joints; the refrigeration design sets the thickness.
Does the foam need a protective coating?
On exposed surfaces a UV-protective coating is applied; under-deck foam inside a shed does not.
Can local applicators buy the chemicals from Wedge?
Yes. Closed-cell SPF drum sets in an imported spec grade and a local fast-supply grade are supplied to applicators in Lucknow and Kanpur.
