In duct installation, what is the specification for duct openings leading into the garage?

In duct installation, especially when it involves spaces such as garages, the correct specification emphasizes that duct openings must be continuous. This is critical because continuous ductwork ensures unimpeded airflow, which is essential for achieving proper ventilation and maintaining efficient heating, cooling, and air circulation throughout a building.

Continuous duct runs reduce the likelihood of air leaks, which can compromise the overall efficiency of heating and cooling systems. Additionally, having continuous ducts minimizes the introduction of contaminants and odors from the garage into the living area, as proper design helps maintain air quality and integrity within the habitable sections of the building.

The other specifications, while they may have relevance in different contexts, do not capture the primary concern of ensuring continuous airflow and system efficiency in duct designs that interface with garage spaces. Maintaining this continuity is vital for the functioning of heating and cooling systems in residential and commercial installations.
