Roof air flow dormers.

They re designed specifically to keep out the elements while making sure that air flow remains steady. This interior dewpoint temperature is approximately equal to an interior conditioned space temperature of 70 degrees f. The dormer has its own roof which may be flat arched hipped pointed or ornamented. Dormer windows may be built into the roof or a wall and they come in many shapes and sizes.

A dormer is a window that is typically set vertically on a sloping roof. That means intake and exhaust vents must be balanced for both position and airflow capacities. If you choose an air permeable insulation like fiberglass or cellulose most building codes require the roof assembly to include a ventilated air gap directly above or directly below the roof sheathing. Windows in eyebrow roof dormers are typically small so they offer less light and ventilation than other styles.

Roof lanterns are a daylighting architectural element that are located atop a roof to provide a natural lighting element to the space below.

First by keeping the roof deck above 45 degrees f condensation will not occur unless the dewpoint temperature of the interior air exceeds 45 degrees f. It s critical that this airflow is uniform. Where this occurs the roof void should have additional ventilation openings. Roof lanterns provide natural light comparable to some low voltage wattage alternatives while also providing ventilation with the proper accessories to ensure adequate flow and efficient air circulation.
