Installation of SmartBaffle16
1- To install the SmartBaffle16 simply bend up the 2” side flanges between a 16” on center rafter space, insert
the flanges into the rafter space ensuring that they rest against the underside of the roof decking. The flanges
will automatically leave a 2” air s pace between the roof deck and the lower panel of the SmartBaffle16. Slide
the SmartBaffle16 down towards the fascia board to about 3” short of the inner side of the fascia board, this
allows room for air flow from under the soffit. SmartBaffle16 is also designed to be used with SmartVent
intake ventilation (
SmartVent opening.
2- The SmartBaffle16 can simply rest in place, or a small nail can be placed proximate the middle on each side,
below the baffle, ensuring the flanges are pressure tight to the roof deck. Install as many SmartBaffles as
needed to create the rafter air chute ensuring that a clear, continuous ai r channel is present between the soffit
intake air and the roof’s exhaust air or ridge vent and the underside of the roof deck. For multiple chute
installations in one rafter bay simply slide one end into the prev i ou s end by about 1” and secure with two tack
nails as shown or tack the end of each flange. Or SmartBaffles can simply abut each piece tightl y without
overlapping.
3- To create a smaller size SmartBaffle16 for nar r ow rafter spaces, simply cut the one long side about four
inches (4”) wider than the width of the rafter space. Next, use a utility knife to cut “half way through” a mark
made 2” in from the SmartBaffle16 cut off edge. This will create a flange that bends up towards the roof
deck.You may practice this cut on a scrap piece of baffle materi al prior to working on th e installed
SmartBaffle to become familiar with the ½ cut. Another way is discussed in step #4.
4- Things to remember: ensure insulation is not inside the 2” ai r chute created between the roof deck and the
SmartBaffle16. Install SmartBaffle16 in all rafter spaces that have soffit intake air flow that may be blo cked
by insulation. Use a utility knife to make cuts. SmartBaffle16 is for use with 16” rafter spacing. Larger spaces
can follow the next step #5 (or purchase SmartBaffle24). Tip: To create a smaller baffle, cut the SmartB affle
long ways ½” less than the width of the rafter space (allowing for the flanges bending up). Once separated,
overlap at the cut edges creat ing the size required including the flange allowances. Screw the overlapped long
edges together using eight 1” long screws pointed towards the roof deck for safety purposes. Install
SmartBaffle16 in the smaller rafter bay and secure as described in #1 & #2 above.
5- To create a larger SmartBaffle16 simply screw two flat SmartBaffles together with maximum length 1”
screws (eight screws with screw points toward the roof deck when installed) ensuring the width is 4” wider
than the rafter space. Then i nstall per the above directions. Below is a sketch of the SmartBaffle16
installation inside a rafter space.
