Thermal insulation for plants, equipment and buildings
Heat kept where it belongs, whichever way it's trying to go, and fitted by people who've done it since 1998.
What thermal insulation actually does
Take a 150 mm steam line running across a yard. Bare, it's losing heat into the air all day and night and nobody can go near it. Wrap it in rockwool and clad it and the heat still leaks out, but slowly, because the wool is full of tiny pockets of still air that heat doesn't cross easily. Nitrile and PUF do the same with closed cells of gas. The upshot is the boiler burns less, the chiller runs less, and the hot surface is safe to brush against.
Our thermal insulation services cover heat going either way. On steam lines, boilers and kilns we're keeping heat in. On chilled water and refrigeration lines we're keeping it out. On buildings it's mostly about the sun on the roof. The idea doesn't change, but the material, thickness and finish do, sometimes a lot.
Areas of application
Thermal insulation materials list, by temperature
Our estimators usually start with the operating temperature because it narrows the choice quickly, and this thermal insulation materials list is roughly what they work from. Grades and brands vary, so we check the actual limit on the datasheet.
| Material | Typical duty | Common uses |
|---|---|---|
| Nitrile rubber | Cold and chilled duty | Chilled water, refrigeration, HVAC pipes |
| PUF and PIR | Cold duty and cold stores | Large chilled headers, cold rooms, panels |
| XLPE and EPS | Light cold and building duty | Condensate lines, floors, roofs |
| XPS | Building duty with load | Terraces, floors, walls |
| Glass wool | Up to about 450 °C | Hot water, ducts, ceilings, roofs |
| Rockwool | Up to about 750 °C | Steam lines, boilers, vessels, walls |
| Ceramic fibre | Up to 1260 °C | Furnaces, kilns, flue ducts |

Choosing thermal insulation contractors
Any of the thermal insulation contractors you call will happily quote a rate per metre. Fewer will tell you what thickness they used and why. Ask for the operating temperature, material, density, thickness and finish on the quote for every line or area. Without those you can't compare two quotes properly, and you can't check the work afterwards either.
We've worked like this since 1998, from our own stock in Ahmedabad and Morbi, on more than 20,000 projects. The written specification comes first. The rate comes after it.
Specification before price. Density, thickness and finish, then a rate.
How we work, the same four steps on a single line or a plant-wide shutdown.
Site visit and measurement
We collect the operating temperatures, sizes and areas, and note where everything is and how we'll get to it.
Specification and quote
Material, density, thickness and finish are picked for each item and written down with the rate.
Supply and installation
Material comes from our stock and our crew fits it, with one supervisor answerable for the job.
Handover and support
Joint measurement, photos and the warranty in writing.
Why plants across Gujarat give us the repeat order.
- Hot, cold and building insulation are all handled by one company.
- Material gets chosen by operating temperature, not out of habit.
- We hold 14 material groups in our own stock.
- Every line, tank or area gets its own written spec.
- Shutdowns, live plants and new builds are all routine for us.
- Joint measurement, photos and a warranty at handover.
Thermal insulation questions, answered.
Still unsure? Send us the duty and a few photos and we will tell you what we would fit.
What exactly is thermal insulation?
It's the layer of rockwool, glass wool, nitrile, PUF or similar that's put on a pipe, tank or building so heat moves through more slowly. You end up using less energy, the temperature inside holds better, and nobody gets burnt on a hot surface.
Which thermal insulation materials are most common?
In our stores the big movers are rockwool and glass wool for hot work and buildings, nitrile and PUF for cold work, and XPS and EPS boards for roofs and floors. Ceramic fibre, PIR and XLPE come up for more specific jobs.
What is a good thermal insulator?
One that traps still air or gas in fibres or closed cells and keeps it there. For a real job it also has to cope with the temperature, the moisture and any knocks or load where it's fitted.
Is thermal insulation the same as hot insulation?
Hot insulation is one kind of thermal insulation. The term also covers cold insulation and building insulation, all of them controlling heat flow, just in different directions.
Do you provide thermal insulation services for buildings?
Yes. Roofs, walls, ceilings and terraces all come under our building, underdeck and overdeck insulation services.
Hot line, cold line or hot building?
Tell us the temperature and the size. We'll put the material and thickness in writing for you, with a rate.
