Nucor Ridge Vents
Nucor Ridge Vents come completely assembled for ease of installation.
The ridge vents supplied by Nucor are of a low profile design
to provide gravity type ventilation. Because gravity ridge
vents are designed to allow free airflow, some penetration
of water during blowing rains is to be expected. Standard
available finishes for the ridge vents are polar white
and Galvalume®.

Other colors may be available at an additional
cost. The ridge vents can be used both with Nucor "Classic Roof ”™
and Nucor "CFR”™ roof systems. Nominal ridge vent
length is 10’-0”. They have flat
skirts for both "Classic Roof”™ and "CFR”™
systems and are attached to the major ribs (or End
Dam on the "CFR"™) with self-drilling screws. Ridge vents
are available with 9” and 12” throats. Bird
screens are provided as a standard.
The ridge vents can
be ordered as continuous or single units. Exterior parts
are 26 gage painted or Galvalume Interior parts are all
made of G90 galvanized steel. The substructure consists
of 10 gage saddle straps with interior baffles of 24 gage
steel. Lifter arms and damper slides are made of 18 gage
steel. Manual operation is through activation of a pull
bar which is attached internally to bell cranked type
lifter arms connected to the damper with Teflon coated
pins through the damper slides. Dampers are spring loaded
to remain in the open position until the pull bar is operated
and locked in the closed position. Dampers operate in
a vertical manner. Each vent is opened by a pull chain
that extends approximately 12” below the roof unless
noted otherwise on the order documents. Other opening
mechanisms are available at an additional cost upon special
request.
Ridge vents should not be placed closer than
5’-0” to the endwall steel line to allow room
to properly flash the building. For example, a 90’-0”
long building with ridge vents required the entire length
should have no more than (8) units.
