What type of duct should residential range hoods be vented with?

Residential range hoods should be vented with galvanized and stainless steel ducting due to several important reasons related to safety, functionality, and code compliance.

Galvanized ductwork is commonly used in residential applications because it is durable, resistant to corrosion, and can handle the high temperatures and moisture that often accompany cooking. Stainless steel ducting offers even greater resistance to corrosion and is particularly beneficial in environments where humidity levels may be high, such as kitchens where steam and grease are products of cooking activities.

Using these materials for ducting ensures that the venting system can effectively remove smoke, steam, and odors from the kitchen while minimizing the risk of fire hazards. Additionally, both galvanized and stainless steel materials are compliant with building codes, which mandate the use of specific materials for ventilation systems to maintain safety standards.

Other materials listed, such as plastic, aluminum, fiberglass, wood, and PVC, may not provide the same level of heat resistance or structural integrity required for kitchen ventilation systems. This could lead to inadequate performance or safety issues over time. Therefore, the choice of galvanized and stainless steel ducting aligns with both practical and regulatory considerations for effective range hood installation.
