Ducting, Insulation and Lagging in Pakistan

AMN Engineering fabricates sheet metal ducting and provides complete insulation and lagging in Lahore, Pakistan. We produce rectangular, round, and spiral ducts in GI and stainless steel for HVAC, ventilation, kitchen exhaust, and fume or dust extraction, made to your drawings or to site measurements.

Beyond the ductwork, we insulate and clad ducts, pipes, and vessels. Thermal and acoustic insulation such as mineral wool, glass wool, or nitrile foam is applied to control heat loss, prevent condensation, and reduce noise, then finished with a protective metal jacket in GI, stainless steel, or aluminium sheet.

Lagging is the insulation and metal cladding applied to pipework and process equipment. The insulation layer manages temperature while the outer cladding protects it from weather, impact, and wear, and gives a clean, durable finish. We handle both the soft insulation and the sheet metal jacketing in-house.

From a single duct run to a full plant, we cut, form, weld, and finish in-house, keeping quality consistent and lead times short. Every job is measured, fabricated, and fitted to specification, with inspection and documentation before delivery.

Frequently Asked Questions

Rectangular, round, and spiral ducts in GI and stainless steel for HVAC, ventilation, kitchen exhaust, and fume or dust extraction.

Insulation is the material that resists heat and noise. Cladding is the metal outer skin over it. Lagging is the combined insulation and cladding applied to pipes, ducts, and vessels.

Yes. We apply thermal and acoustic insulation such as mineral wool, glass wool, or foam, then fabricate and fit the GI, stainless, or aluminium cladding over it.

Yes. We fabricate to drawings or measure on site, then supply ducts and lagging ready to install.

Yes, we export worldwide, including the USA, UK, Germany, and the GCC.
