A raised cover for the ridge vent can also be used. However, the gap between the bottom of the cover and the ridge vent should be the same size as the ridge vent. Provide a 2 - 3 ft overhang along each sidewall. Size eave vents in a similar manner as ridge vents. Provide 1 inch of continuous eave opening per 10 ft of building width on each side of the building.
Curtains provide the easiest and least expensive method to provide open sidewalls during summer.
