What product is used to allow reduced spacing around electrical boxes in firestop installations?

The use of putty pads in firestop installations specifically addresses the need for reduced spacing around electrical boxes. Putty pads are designed to provide a fire-resistive barrier that helps maintain the overall fire rating of a wall or ceiling assembly while accommodating the presence of electrical boxes. This is particularly important in ensuring that the integrity of fire barriers is maintained, minimizing the risk of fire and smoke spread through any gaps or openings that might otherwise exist due to the installation of these boxes.

Putty pads effectively fill in the gaps while allowing for some logistical flexibility in the placement of electrical installations, which can help in achieving code compliance during construction. Their formulation also supports durability and can continue to provide protection even under thermal stress, which is crucial in a fire scenario.

Other products, such as fire caulk, sealants, and fire foam, serve various roles in firestop systems, but they do not specifically cater to the unique requirements of reducing spacing around electrical boxes in the same way that putty pads do. Therefore, putty pads are the optimal choice for this particular application.
