SDF-20CM (Curb Mount
designed for curb mount installations. Generally a 2"x4" or 2"x6" curb
box is built and flashing is attached to the perimeter of the curb box.
Curb mount installations should be used on flat or very low slope
roofs. Curb mount installations are also recommended for higher profile
roofs, such as ceramic or concrete tile, certain metal roofs, thick
wood shake, etc. The flashing materials are generally metal, but can be
made of certain types of roofing materials. Care should be taken to
isolate dissimilar metals and to properly waterproof the curb box to
the roof. On top of the curb box, attach weather stripping or two sided
foam tape. Place the SDF-20CM base on top of the curb box and fasten at
least two screws on each side into the curb box.

Benefits of a Solar
Powered Super Cyclone
All attic ventilators, powered or solar vent out the hot air built up
within the attic, but a solar unit offers additional benefits not
possible with a powered product. Because a Solar Dynamics PAV turns on
at dawn, it goes to work immediately, first to eliminate the moisture
that has built up from the cool overnight air, and second, to prevent
heat build up before it has a chance to build up to the point of
convection. A standard PAV has to reach a high temperature before the
thermostat kicks in and tells it to start working. By this time the
moisture has already worked its way into the insulation and the walls,
doing its damage. Because it has to play “catch-up” the PAV is already
starting out at a disadvantage and must run all day. Driven off AC
power, a PAV can be noisy emitting “harmonic noise”, and although it is
possible to override the thermostat and let it run, the motor is not
designed to handle this constant demand.
