Who we are
One contractor, from the boiler house to the chiller plant.
Most insulation jobs need two different vendors — one for the thermal system, one for the metal cladding that protects it. Raj Insulation has run both under one roof since 2000: our crews spec the right material for the service temperature, and our own sheet-metal shop fabricates the elbows, boxes and jacketing to fit.
The shop sits at C-233, MIDC, Ratnagiri, Maharashtra, India. The work goes anywhere in India — fewer contractors on your site, and cladding that's actually cut for the pipe in front of us.

Method · REV A
Survey, spec, fabricate, install — in that order.
The cladding is cut for the pipe in front of us, not pulled from a generic kit.
Spec the system
Material, thickness and cladding grade selected for the actual duty — hot, cold, HVAC or acoustic.
Fabricate in-house
Elbows, boxes, jackets and flashing cut and rolled in our own aluminium, SS and GI shop.
Install & close out
Fit, vapour-seal, weatherproof and hand over with the cladding already made for the pipe it sits on.

Material selection · REV A
Materials, and where they actually fit.
The right system depends on service temperature and exposure — not just what's on the shelf.
| Material | Where it's used |
|---|---|
| Rockwool / mineral wool | Hot piping, vessels, boilers, tanks, personnel protection |
| Calcium silicate | Higher-temperature rigid pipe and equipment insulation |
| ArmaFlex / elastomeric | Chilled water, refrigeration, HVAC and condensation control |
| PUF / PIR | Cold applications, refrigeration and select process applications |
| Glasswool | HVAC, ducts, tanks and moderate-temperature applications |
| Acoustic boards / mineral wool | Enclosures, duct lining and noise control around equipment |
