- Install Drain-Plane furring strips vertically at the stud locations over sheathing and weather barrier wherever cladding is to be installed. Drain-Plane should lay flat against the wall and be installed with standard siding nails.
- Leave approximately a ¼” space between each strip as you install them vertically along the stud.
- Install siding or cladding system over wall surface per manufacturer’s installation instructions.
- Allow for thickness of Drain- Plane (1/4”) in nail selection.
- * Do not over nail when tacking on furring strips (approximately 6 – 8 nails recommended).

To prevent insect infiltration in the drainage plane between the siding and the water protective barrier, a screen material (not provided) can be installed around the Drain-Plane product.
- Fasten a 6” wide screen material (1/8” recommended hole size) along the wall approximately 3” above the bottom of the wall.
- Install first run of Drain-Plane along bottom of the wall.
- Fold up the screen material over the Drain-Plane strips and fasten with a large-head nail to hold in place prior to applying your siding.

| Installation at the top of the wall can include the use of a screen material (not provided) to prevent insect infiltration. It also requires proper spacing techniques creating airflow for drying, ventilation, and pressure equalization. |

With new construction or the removal and replacement of the soffit on a remodel application, installing the Drain-Plane product past the soffit is recommended.
- Run Drain-Plane past the soffit overhang at least 4”to 6” to accommodate the soffit fastener.
- Install the soffit fastener to the Drain-Plane product.
- Finish installation of siding or cladding and install soffit.

There are two different visually appealing options for installing Drain-Plane in applications where the soffit is already installed whether the soffit type is fiber cement or aluminum.
- Fasten a 6” wide screen material (1/8” maximum hole size) along the wall approximately 4” below the soffit overhang.
- Run Drain-Plane to within 1/8” to ¼” of the soffit. The gap allows for the necessary airflow.
- Fold down the screen material over the Drain-Plane strips and fasten with a large-head nail to hold in place prior to applying your siding.
- Finish installation of siding or cladding to within ½” to ¼” of soffit overhang.
- Modify Step 2 above by running Drain-Plane to within 3¼” to 3½” of the soffit.
- Modify Step 4 above by finishing installation of siding or cladding to within 3½” to 3¾” of soffit overhang.
- Install a 1”x3” board on the finish wall above the siding and Drain-Plane leaving the 1” gap for airflow.
- Install a 1”x4” finish trim board or 4” piece of siding over the 1”x3” board. This will maintain the airflow gap yet provide an alternative visual appearance.

- Identify location and width of trim boards for outside and inside corners. Any trim board greater than 2” in width should be backed by 2 or more Drain-Plane runs.
- Install 2 strips Drain-Plane at inside and outside corners behind trim pieces to maintain proper depth and backing and to provide the appropriate stability.
