RE: Eagle Center Vent Ventilation Standards
This memo is to update the information regarding the ventilation provided by each of
our skirting ventilation panel programs. Please note the changes in the center vent
panel specifications. This revision is due to a tolerance change allowing us to realize
the full potential of the basketweave vent panels.
Premium Full Vent 15.5 & Vent per lineal ft of vented panel
Eagle Full Vent 9.0 0 Vent per lineal ft of vented panel
Eagle Center Vent Panel 4.9 in2 Vent per lineal ft of vented panel
Premium Center Vent Panel 8.4 0 Vent per lineal ft of vented panel
All vented panels will have a 0.050" depth run condition with a +/. 0.005" tolerance.
The center vented ventilation figures stated above are based on vent at the 0.050"
depth of the basket weave. The full vent ventilation figures given above are based
on current marketing information that is being used.
If there are questions, please contact me.

T e reason many installers use
Premium Plus Trim Kits with Eagle Panel is because it is HEAVIER;
aqd, in areas where blow-out is a
problem, Premium Plus offers more rigid protection against blow-out.

NUFACTURED HOME VENTILATION'
I manufactured homes must be properly ventilated. Every
anufacturer provides installation and set-up instructions. The
3tional Conference of States on Building Codes and Standards
is issued an American National Standard which is the minimum
quirement for ventilation when setting up and installing skirting for
manufactured home.
Tf'�e code states the following:
American National Standard
(NCSBCS) -
Manufactured Home Installations
li NSCBCS/ANSI A225.1-1994
..�'Ventilation shall be provided for the crawl space at a minimum of
o' e sq. ft. of FREE AREA for every 150 sq. ft. of the homes FLOOR
k 8A. Ventilation shall be placed at or near, each corner of the home
and as high as practicable. Opening shall be located to provide
i cross -ventilation on at least two (2) OPPOSITE sides.
Where acceptable ground VAPOR BARRIER is installed and one
ich ventilation opening is within 3 ft. of each corner of the home,
TOTAL AREA of ventilation openings may be REDUCED to one (1)
sq. ft. for every 1,500 sq. ft. of the home's floor area.
" i,here LOCAL CODES have MINIMUM ventilation requirements for
cr wl spaces, these requirements shall apply to homes with skirting
11 and continuous foundations."
