To prevent insulation from blocking the soffit vents and to provide attic ventilation channels between the soffit vents and the attic, insulation baffles are used. Rectangular channels spaced and sized to fit, connecting a number of flat panels make up the construction of ventilation baffles. The channels are generally secured to the tops of the rafters in a building construction before placing the sheathing over the rafters.
