Underfloor Duct

Definition

An underfloor duct is a round or rectangular metal pipe placed within a concrete floor to distribute warm or cool air from a heating or air conditioning system.

Purpose

Underfloor ducts are used to improve the distribution of conditioned air within a building, enhancing heating and cooling efficiency. They are particularly useful in buildings with concrete floors where traditional above-ground ductwork is impractical.

Examples of Use

• Office Buildings: Underfloor ducts in open-plan offices to provide efficient heating and cooling without obstructing the layout with overhead ductwork.
• Residential Homes: In homes with concrete slab foundations, underfloor ducts are used to distribute air from HVAC systems.
• Commercial Spaces: Retail stores and other commercial spaces utilize underfloor ducts to maintain a comfortable indoor environment.

Related Terms

• Ductwork: The system of ducts used to deliver and remove air in HVAC systems.
• HVAC: Heating, Ventilation, and Air Conditioning systems that regulate indoor climate.
• Plenum: A space or chamber where air is distributed in HVAC systems.

Notes

Proper insulation of underfloor ducts is crucial to prevent heat loss or gain, ensuring the efficient operation of the HVAC system. Regular inspections are also necessary to check for potential leaks or damage.
