In addition to fitting easily, the design fits between the roof underlay overlaps, below the tiles or slate, and introduces ventilation openings. It's shallow and tapered to fit most common rafter spacings. As is often the case after loft insulation is upgraded, this method is ideal when roof space ventilation is lacking or preexisting ventilation pathways are blocked.
