• Vented Cut-To-Width (CTW) sot provides ventilation of 10 square inches per linear foot from the factory.
• Exhaust ducts shall terminate not less than 3 ft. in any direction from openings in vented sot. Refer to your local code.
• When cutting sot panels with a circular saw, orient the texture face down and fully support and brace to reduce vibration.
• Layout and install vented sot in a manner that reduces or eliminates the need to cut through the vents. All sot edges
must be supported or backed by minimum 2x support. (See diagrams 6b to 6d)
• If the panels need to be eld-cut to width, cut them 3/8 inch short to leave a 3/16 inch gap on each side. At all edges
and ends, leave a 3/16 inch space and apply sealant. Nail the panels 6 inches o.c. at the edges and 12 inches o.c. along
intermediate supports. Always prime and paint all exposed edges.
• The spokes within the vent may distort slightly during equilibration with the local environment. This condition is temporary
and the spokes will straighten.

• Vented Corner with Square-Cut Ends: (See diagram 6b)
Run vented sot all the way to the corner and butt the straight-
cut edges of the sot without cutting through the vents. Make
sure that the vents do not land closer than 3 inches from the end
or corner. Do not make diagonal cuts through the vents.
• Non-Vented Corner with Square-Cut Ends: (See diagram 6c)
You may use both vented and non-vented sot in your design.
For this layout you will use the vented sot to span the straight
runs, and use the non-vented sot to cover the corners. By using
non-vented corner pieces that are square-cut you can layout the
sot for either a symmetrical or non-symmetrical look. All sot
lengths must span a minimum of 48 inches.
• Non-Vented Corner with Diagonal-Cut Ends: (See diagram 6d)
The diagonal joint must be supported by framing and properly
fastened.
• If building codes require a certain ratio of sot ventilation that
requires you to utilize ventilation space at corners, your options
might be limited. Be sure to follow your local building codes.
