Why Professional Installation Matters
Airtight duct joint sealing, correct metal gauge selection, and proper thermal insulation prevent air leakage losses, prevent ceiling sweating, and lower fan static pressure requirements.
Step-by-Step Installation Process
Our systematic approach ensures reliable performance and safety.
Site Measurement & Detailing
Taking exact site dimensions and preparing shop drawings.Duct Fabrication
Cutting, bending, and flanging GI sheets into duct sections.Support Erection
Fixing anchor fasteners, threaded rods, and MS angle supports.Duct Raising & Flanging
Hoisting duct pieces, inserting gasket tape, and bolting flanges.Insulation & Air Balancing
Applying thermal insulation and balancing airflow at diffusers.HVAC Ducting Technical Considerations
GI sheet gauge selection must follow SMACNA standards (24G for width < 450mm up to 18G for width > 1500mm). Duct joints must use neoprene gasket tape to achieve Class C air tightness.
Frequently Asked Questions
Common questions regarding HVAC Ducting Installation Services in Delhi NCR.
Q: What sheet metal gauges are used for GI duct fabrication?
A: We fabricate GI ducts using 24G, 22G, 20G, and 18G zinc-coated steel sheets depending on duct size and pressure class.
Q: Why is thermal insulation critical for conditioned air ductwork?
A: Thermal insulation prevents cool air temperature rise inside duct runs and stops surface condensation dripping in ceiling voids.
Q: What is the function of Volume Control Dampers (VCDs) in ducting?
A: VCDs modulate airflow volume in main ducts and branch lines to achieve balanced CFM distribution across all rooms.
Q: Why are fire dampers installed at wall penetrations?
A: Motorized fire dampers automatically close upon sensing heat/smoke, preventing fire and smoke spread through ductwork.
Q: What is Pre-Insulated Ducting (PID) and where is it used?
A: PID ductwork uses rigid polyisocyanurate (PIR) foam panels with aluminum facing, offering lightweight, pre-insulated duct construction.
