What type of product is suited for large high-traffic openings that allows for easy access?

Firestop pillows are specifically designed for large, high-traffic openings where easy access is necessary. These pillows are flexible and can be easily added or removed, allowing for quick adaptations in areas that may require frequent changes, such as maintenance access or revising utility pathways. Their construction allows them to withstand fire conditions while remaining accessible, which is essential for applications in dynamic environments.

While firestop caulk and silicone sealant are useful for sealing gaps and joints, they may not accommodate the same level of accessibility for regular operations, particularly in high-traffic areas. Standard mortar mix is typically used for fixed installations and would not offer the flexibility needed for openings that require regular access. Thus, firestop pillows stand out as the optimal choice for such applications, combining fire resistance with the practicality of being readily accessible.
