You ll need to crawl to the end of the eave and staple the baffle against the roof deck.
Installing attic soffit baffles.
You will need a baffle for each space between the rafters.
Attach this roof and attic insulation treatment using foam baffles to ventilate insulate and channel cold and hot air to roof vents before insulation is add.
Soffit vents and baffles work in tandem together and you will usually find attic baffles between the rafters or the roof sheathing in order to create protection for the soffit vents.
So why install a baffle.
Pull any existing insulation away from the edges of the attic where you will be putting up the baffles.
If you are finishing the entire attic space place the baffle directly adjacent to the soffit vent so air vents directly into the tray of the baffle and is captured.
Staple each side to the roof deck spaced about every 4 inches.
Position the first baffle.
If your roof rafters have been covered over with drywall or plywood you will have to remove it in order to install the baffles.
Step 2 in the bay.
The outside edge of the baffle should be parallel to the exterior wall sheathing.
