Overview
Sandwich panels are the envelope of every cold store, ripening chamber, dairy, pharma clean room and pre-engineered warehouse in the potato and food belt around Hardoi, Kanpur, Unnao, Farrukhabad and Agra. Wedge Industries Limited supplies PUF and PIR panels from partner lines on merchant terms, and sells them the way they are actually bought — as a cold-room kit with doors, floors and accessories, or as a wall and roof package with the prefab or LGSF structure.
PIR gives the highest R-value per millimetre of any insulated panel and is self-supporting, so it cuts secondary steel and installs fast with the interlocking joint. Wedge’s cement-faced CSP panels (2 × 10 mm fibre cement over a poured PUF core) cover internal partitions, site offices and cabins.

Applications in Lucknow and the region
- Potato and multi-commodity cold stores and ripening chambers (Hardoi, Kanpur, Unnao, Farrukhabad, Agra)

Installation and specification notes
Panels are fixed to steel purlins or a light-gauge frame with self-drilling fasteners and sealed at joints; cold rooms use cam-lock panels on a PUF or XPS-insulated floor with foam-glass or XPS under the slab. Wedge supplies the panels, doors, flooring boards and an installation crew, or panels alone to the contractor.

Frequently asked questions
PUF or PIR — which should I use for a cold store?
PIR has better fire performance and the same thermal value; PUF is the economical choice for ambient warehouses and partitions. Cold stores in the potato belt are usually 100–150 mm PUF/PIR walls and roof.
What thickness of panel do I need for a −20°C room?
150 mm is usual for frozen rooms, 100 mm for chilled and 60–80 mm for ambient/insulated warehouses; Wedge confirms thickness from the refrigeration load calculation.
Do you supply cold-room doors and floors with the panels?
Yes — sliding and hinged cold-room doors, XPS floor boards, foam-glass and accessories are supplied as a kit; see the cold-storage package page.
Can panels be delivered directly to Agra or Farrukhabad?
Yes. Full-load orders are dispatched direct from the panel line to site anywhere in the belt; small orders join the regional consolidated delivery.
What about cement-faced panels for site offices?
Wedge’s CSP-50/74/99 cement-sandwich PUF panels in 8 × 4 ft are made at Faridabad for partitions, cabins and site offices where a steel facing is not wanted.
