E) Is stronger than a concrete block at the reveal

Question

Quizplus · Accepted Answer

A cavity closer is designed to prevent thermal bridging at the reveal, by fully insulating the gap between the window frame and the interior wall. This helps to improve the energy efficiency of the building and reduce heat loss through the opening. While some cavity closers may have other features like fins to prevent air infiltration or colors to reflect solar radiation, the primary advantage is their insulation properties.
