been looking to add some insulation and install soffit vent channel in
the attic.

does the channel has to be installed in ** all ** the void between the
rafters or just a few around where the vents are?

thanks
richard

The baffles are so the insulation won't cover the intake (vent). They are
installed for blown in insulation. The bay created by the rafters will
direct the intake towards the peak.

Some will argue you absolutely need baffles, but think about it b/4 putting
them in. As long as you don't block the intake (vent), you will get the
same result without them.
