Frequently Asked Questions (FAQs)
Rectangular duct pricing typically starts from ₹54 per sq ft, depending on material, thickness, insulation, and project requirements.
Both have their advantages. Rectangular ducts are ideal for space-constrained areas and false ceilings, while round ducts offer better airflow efficiency. The choice depends on the specific application and project needs.
GI ducts are generally manufactured with thickness ranging from 0.5 mm to 1.25 mm, depending on duct size and pressure requirements.
Insulated ducts are recommended in applications where temperature control, energy efficiency, and condensation prevention are critical. The requirement depends on the use case and environment
Prefabricated ducts offer higher precision, faster installation, reduced leakage, and better finish compared to traditional handmade ducts, making them more efficient and reliable for modern HVAC projects.
