InvisiVent Soffit
Installation over open eaves
In most situations, InvisiVent
™
Super Ventilated Soffit should
be installed like our standard soffit products. However, when
InvisiVent is installed over open eaves, follow these installation
techniques.
Install receiving channels
There are two ways to install receiving channels for soffit.
The best approach is to select a method that works most
effectively with the construction techniques used to create the
eave. Examine the illustrations, and find the one that most
closely resembles the construction methods on your particular
project.
Use either 3/4" J-channel or 3/4" F-channel, or you can make
receiving channels using coil stock.
Install the receiving channels following the details shown in the
illustrations.
Nail the channels every 12" to 16", positioning the nail in the
center of the slot. Do not nail tightly.
NOTE: If you are concerned about excessive insect
infiltration, cover the opening with corrosion-resistant
mesh or other screening before installing the soffit.
Install soffit
Nail the soffit every 16" or 24", depending upon local building
codes and stud spacing. InvisiVent will span up to 24" without
additional nailing strips.
Installation over existing soffit
When installing InvisiVent Soffit over an existing solid wood
soffit, you must cut openings into the existing soffit to provide
adequate airflow through the InvisiVent Soffit. The goal is to
have at least 9 square inches of net free air per lineal foot of
soffit. Removing a center portion of the existing soffit will
provide the desired airflow.
Using a saw, cut along the length of the existing soffit. Leave
2" to 3" from both the wall and the fascia so that you will have
enough wood surface to securely fasten the InvisiVent.
Remove the center portion of the existing soffit.
Install the InvisiVent Soffit as described above.
