Bases for Rotary and Stationary Vents
Description
Vents bases are the components of a ventilation system that provide a stable and secure foundation for stationary or rotary vents to be installed on. These bases are typically made from a durable material such as galvanized steel, aluminum, or plastic and are designed to withstand the elements and protect the roof or building structure from damage.
The type of stationary and rotary vent base required depends on the specific type of vent being installed. For example, ridge vents require a ridge cap or end cap to be installed at the top of the roof to provide a secure base, while soffit vents require an appropriate soffit material to be installed to create the base.
Frequently Asked Questions
How should airflow capacity be evaluated for Bases for Rotary and Stationary Vents?
The base does not establish airflow capacity; use the performance data for the compatible rotary or stationary vent mounted on it.
Which is better for Bases for Rotary and Stationary Vents, galvanized or aluminum?
For Bases for Rotary and Stationary Vents, galvanized steel is the general-purpose choice; aluminum is lighter and will not rust.
Why does a rotary or stationary vent need a base under it?
Since standard rotary vents are not equipped to be fitted directly to the roof, bases help to provide a stable, weather-tight mounting surface between the various roofing systems and the vent's top section.
Which metals do you make Bases for Rotary and Stationary Vents in?
Bases for Rotary and Stationary Vents are made from 26 gauge or thicker galvanized steel.
What airflow applications use Bases for Rotary and Stationary Vents?
The base supports a compatible rotary or stationary roof vent; the attached vent determines whether the assembly provides passive or wind-driven exhaust.
