Divided into two types:
Roof (horizontal enfc, on sloping roofs, curved roofs or Sheds)
Wall (enfc applied to vertical building walls)
The difference in type lies in the SUA value (Aa). In fact, roof ENFCs, being very exposed, require a SUA value tested with the wind blowing against
the flue outlet to ensure efficiency even in cases of evacuation in extreme situations. For this reason, roof vents applied to sheds require protections
that act as wind screens, as they are very exposed because they are arranged vertically, while horizontal vents, even with blowing wind, create a
chimney effect exhaust and easily expel fumes.
Wall vents, as they are highly influenced by the wind, undergo enforcement by regulations and must ensure an opening both upwind and downwind.
For this reason, mirrored application is required with the wind sensor so as to always open the correct number of devices with favourable wind.
