Overview
Insulated Duct Casings for Thermal and Condensation Control
NESF supplies insulated duct casings to control heat loss or gain, condensation, and energy losses, and to protect personnel or nearby equipment from hot or cold duct surfaces.
These casings are especially relevant where ducts run through non-conditioned zones, outdoors, or in duties with significant temperature differences.
Share your duct layout, temperatures, insulation specification, casing material, and environmental conditions. NESF will propose a fabrication-ready insulated casing scope.
Where Insulated Duct Casing Is Used
- Supply and return air ducts through non-conditioned zones.
- Outdoor duct runs exposed to weather.
- Cold-air lines where condensation risk is high.
- Hot-exhaust ducting requiring surface-temperature control.
Typical Construction Options
- GI or stainless-steel outer casing.
- Insulation thickness and density as per project requirements.
- Vapour-barrier and cladding provisions where required.
- Flanged or bolted joints for maintenance-friendly installation.
Fabrication & Integration Focus
- Accurate casing dimensions and connection fit-up.
- Provisions around supports, flanges, access doors, and interfaces.
- Weather and outdoor-exposure considerations.
- Modular fabrication for transport and site assembly.
Standards & References
Project insulation requirements can align with applicable energy and building standards such as ASHRAE 90.1, depending on duct location, application, and client specification.
Quotation Inputs
- Duct sizes, layout, operating temperature, and ambient conditions.
- Required insulation thickness, density, and thermal performance.
- Outer casing, vapour barrier, cladding, and weatherproofing requirements.
- Access, supports, connections, inspection, and delivery requirements.
