What is the minimum ventilation required with openings to the exterior for an insulated roof space?

1/200 of the insulated ceiling space.
1/ 300 of the insulated ceiling space.
1/400 of the insulated ceiling space.
1/500 of the insulated ceiling space.

The correct answer is: 1/ 300 of the insulated ceiling space.

The correct answer is B, 1/300 of the insulated ceiling space. This means that for every 300 square feet of insulated roof space, there should be at least one square foot of ventilation opening to the exterior. This is the minimum requirement to ensure proper ventilation in a insulated roof space. Option A, 1/200 of the insulated ceiling space, is incorrect because it would require more ventilation than is necessary, potentially leading to excess air flow and energy loss. Option C, 1/400 of the insulated ceiling space, and Option D, 1/500 of the insulated ceiling space, are also incorrect for the same reason. It is important to remember that proper ventilation is crucial for the health and longevity of a building's structure and the well-being of its occupants. It prevents moisture buildup, which can lead to mold and rot, and helps regulate temperature and air quality.
