Insulation contractor in Ludhiana: the industrial belt we cover
Ludhiana and the Mandi Gobindgarh belt run on furnaces and steam — induction and reheating furnaces in the steel cluster, thermic-fluid heaters and boilers in the dyeing and hosiery mills, and a large, growing cold-storage base for potato, dairy and processed food. Punjab winters also make building-side insulation worth doing properly: hot-water and boiler distribution lines in mills lose a great deal between November and February if they are bare.
We take enquiries from across the Ludhiana industrial belt, including Focal Point Phase I–VIII, Dhandari Kalan industrial area, Industrial Area A and B, Mandi Gobindgarh steel belt, Doraha, Khanna and Sahnewal and Jalandhar and Phagwara corridor.

Top 20 insulation products we supply and install in Ludhiana
As an insulation contractor in Ludhiana we hold or make to order everything on this list. Every product below is supplied from stock or manufactured to order, and can be installed by our crews as part of a supply-and-apply or turnkey contract. Thicknesses, densities and facings are selected against your operating temperature and application after a heat-loss calculation.
| # | Product | What it is used for |
|---|---|---|
| 1 | Aerogel Blanket (WedGel) | Flexible silica aerogel blanket, thermal conductivity from about 0.015 W/mK, service up to 650°C. The thinnest option when space is tight — steam lines, tracing, refinery piping and confined equipment. |
| 2 | Calcium Silicate Board & Pipe Sections | Rigid, load-bearing hydrous calcium silicate to IS 8183 / ASTM C533, service up to 1000°C. Boiler walls, furnace back-up lining, hot piping and equipment where mechanical strength matters. |
| 3 | Ceramic Fibre Blanket, Board & Modules | Alumino-silicate wool in blanket, board, module and paper form for 1050–1430°C classification temperatures. Furnace and kiln linings, ladle covers, flue ducts and expansion joints. |
| 4 | Microporous Insulation Board | The lowest thermal conductivity rigid board available for high temperature, service up to about 1000°C. Used as a thin back-up layer where shell temperature has to drop without adding thickness. |
| 5 | Rock / Mineral Wool Slab, LRB Mattress & Pipe Sections | Non-combustible mineral wool to IS 8183 / ASTM C592, service up to 750°C, densities 48–150 kg/m³. The workhorse for boilers, steam lines, ducts, tanks and acoustic infill. |
| 6 | Glass Wool Rolls, Slabs & Pipe Sections | Lightweight glass wool up to about 250°C, faced or unfaced. HVAC ducting, AHU rooms, false ceilings, roof under-deck and acoustic absorption. |
| 7 | Spray Polyurethane Foam (SPF) | Site-applied closed-cell PU foam, applied seamlessly to roofs, tanks, cold rooms and irregular surfaces. Insulation and waterproofing in one pass, with no joints for vapour to travel through. |
| 8 | PUF / PIR Sandwich Panels | Factory-made insulated panels, 40–200 mm, with cam-lock or tongue-and-groove joints. Cold rooms, freezer stores, clean rooms, ripening chambers and prefabricated building envelopes. |
| 9 | XPS Extruded Polystyrene Board | High compressive strength closed-cell board with very low water absorption. Cold storage floors, under-deck roofing, plinth and below-grade insulation. |
| 10 | EPS Board, Block & Thermocol | Expanded polystyrene in cut boards and blocks, densities 15–32 kg/m³. Cost-effective wall, roof and cold room infill and packaging-grade thermal protection. |
| 11 | Nitrile Rubber (NBR) Elastomeric Sheet & Tube | Closed-cell elastomeric insulation with a built-in vapour barrier for chilled water, refrigerant, brine and glycol lines. The default choice for dew-point control on cold service. |
| 12 | XLPE Foam Sheet & Rolls | Cross-linked polyethylene foam, closed cell, light and clean to handle. Duct wrapping, refrigerant lines, under-deck and vehicle or equipment thermal-acoustic lining. |
| 13 | Vacuum Insulated Panels (VIP) | Evacuated core panels with thermal conductivity around 0.004 W/mK — roughly five to eight times better than conventional board at the same thickness. Used where every millimetre counts. |
| 14 | Perlite & Vermiculite Products | Expanded perlite and vermiculite as loose fill, boards and castable mixes for cryogenic tanks, furnace back-fill, fire-resistant screeds and high-temperature infill. |
| 15 | Refractory Bricks, Castables & Mortars | Insulating fire bricks, dense and low-cement castables, ramming mass and mortars for furnace, kiln, boiler and ladle linings, supplied with the back-up insulation to match. |
| 16 | Aluminium & Stainless Cladding, Jacketing and Accessories | 0.5–0.9 mm aluminium and stainless sheet, foil facing, bands, cleats, self-tapping fixings, insulation pins and mastics — the finishing system that decides how long the insulation actually lasts. |
| 17 | Intumescent Fire Seals & Fire-Stop Systems | Intumescent strips, wraps, collars, pillows, sealants and mortars that expand under heat to close service penetrations through rated walls and floors. |
| 18 | Fire Door Boards & Vermiculite Fire Boards | Non-combustible core boards for fire doors, shafts, duct enclosures and structural steel encasement, tested to BS 476 / EN 13501 classifications. |
| 19 | Acoustic & Soundproofing Sheets, Panels and Barriers | Mass-loaded barriers, acoustic foam, wool panels and composite lagging for DG rooms, AHU plant rooms, ducting, compressors and machine enclosures. |
| 20 | MgO Boards & Fibre Cement Boards | Non-combustible magnesium oxide and fibre cement boards for drywalls, ceilings, external cladding, prefab panels and fire-rated partitions. |

What a turnkey contract with an insulation contractor in Ludhiana includes
- Site survey and thermal audit. We measure surface temperatures, line sizes, operating conditions and access, and photograph the existing condition before quoting.
- Heat-loss and thickness calculation. Thickness is calculated from hot-face temperature, ambient, wind speed and the target cold-face or dew-point condition — not copied from what was there before.
- Material supply with test certificates. Manufactured or sourced from our own units in India, UK, Spain and China, supplied with material test certificates and thermal conductivity data.
- Fabrication and cut-to-size. Boards, pipe sections, removable jackets and modules pre-fabricated to your drawing so site time is installation, not cutting.
- Installation by trained crews. Applicator teams working under a Wedge Industries Limited supervisor, to a method statement, with PPE, height and hot-work discipline.
- Cladding and finishing. Aluminium or stainless jacketing, bands, sealing and weatherproofing detailed for the actual exposure — coastal, corrosive, abrasive or indoor.
- Inspection, thermography and handover. Completion check with surface-temperature readings or thermography where specified, plus measurement sheets, MTCs and an as-installed record.
- Annual maintenance and shutdown support. Planned relining and repair work executed inside your shutdown window, with material pre-positioned before the plant comes down.
Why choose Wedge as your insulation contractor in Ludhiana
- Manufacturer, not a trader. Own manufacturing in India, UK, Spain and China, so material specification, lead time and price are ours to control.
- One vendor across the whole range. Hot, cold, acoustic and fire protection from a single contract, instead of four sub-contractors blaming each other at the interface.
- Calculation-led proposals. Thickness and material come from a heat-loss calculation with stated inputs, so the proposal can be checked rather than trusted.
- Documentation with every job. Material test certificates, thermal conductivity data to ASTM C177, measurement sheets and an as-installed record.
- Export-grade quality control. The same material specification supplied to buyers in over 45 countries.
- Most Ludhiana mills want a straight answer on payback — we put the heat-loss and fuel saving next to the quote so the decision is a commercial one.

Frequently asked questions
Do you work as an insulation contractor in Ludhiana or only supply material?
Both. In Ludhiana we take work as material supply only, as supply-and-apply, or as a complete turnkey contract covering survey, heat-loss calculation, fabrication, installation, cladding and handover documentation.
Do you cover Mandi Gobindgarh and Jalandhar from Ludhiana?
Yes. The Punjab scope covers Ludhiana Focal Point, Dhandari Kalan, Sahnewal, Doraha, Khanna, Mandi Gobindgarh, Jalandhar and Phagwara.
What is the minimum order for an insulation job in Ludhiana?
There is no fixed minimum for material supply. For installation work we normally quote from a measured scope, and small jobs are priced as a day-rate crew plus material rather than per square metre.
How quickly can you start work in Ludhiana?
Standard materials are dispatched from stock; fabricated items such as pipe sections, removable jackets and cut-to-size boards are made to order. Site mobilisation is confirmed against your access window and permits — shutdown work is planned in advance so material is on site before the plant comes down.
How do you decide the insulation thickness?
From a heat-loss calculation using hot-face temperature, ambient temperature, wind speed and the target cold-face or dew-point condition. We state those inputs in the proposal so the result can be checked.
Which insulation materials do you supply for high temperature service?
Ceramic fibre blanket, board and modules for up to 1430°C, microporous board and calcium silicate up to about 1000°C, aerogel blanket up to 650°C, and mineral wool up to 750°C — usually combined as a layered system with refractory at the hot face where required.
