4. Can be used on various types of walls: Sti EzdR400 can be used on different types of walls, including gypsum, masonry, and concrete, making it a versatile option for firestopping wiring in various construction types.

1. Expensive: Compared to other types of firestopping materials, Sti EzdR400 is more expensive.

2. Requires precise application: The product needs to be applied correctly to ensure effective firestopping. Any mistakes or inconsistencies can compromise the fire resistance of the wall.

3. May require additional accessories: Depending on the specific application, additional accessories such as backer rods or firestop collars may be required, adding to the overall cost.

Sti EzdR400 is an effective firestopping solution for wiring penetrations in fire-rated walls and partitions. Its ability to meet fire codes and standards, easy application, and effective sealing make it a valuable option. However, its high cost and the need for precise application may make it a less desirable choice for some projects.

If budget is a concern or the application is not critical, alternative firestopping solutions such as intumescent paint or pre-formed firestop systems may be more cost-effective options. However, for critical applications or construction types where fire resistance is a top priority, Sti EzdR400 is a reliable and effective choice. Ultimately, the decision to use Sti EzdR400 or another firestopping solution should be based on the specific project requirements, budget, and the level of fire resistance needed.
