Overview

Duct Insulation Engineering

Thermal + acoustic duct insulation systems for ventilation, exhaust, and process gas ducts across process plants, commercial buildings, and manufacturing facilities.

From foil-faced HVAC duct wraps to hot-service exhaust ducting with SS cladding, our duct-insulation crews deliver clean, energy-efficient, and codes-compliant finishes.

All Shapes Rectangular, round, oval ducts
Hot Service Exhaust ducts up to 500°C
Acoustic Combined thermal + noise damping
ASHRAE Compliant Per building-code specifications

Frequently Asked

Duct Insulation FAQs

Typically 25 mm for cold-air supply ducts and 40–50 mm for hot exhaust. Exact spec is per ASHRAE / ECBC and your ambient conditions.

Yes — with foil-faced fibreglass wrap or blankets. Access is critical: we plan the wrap sequence with your ceiling installer.

We partner with duct fabricators when required. For pure insulation scope, we work over already-installed ducts.
