What is a major factor in determining the success of a firestop system?

The success of a firestop system largely hinges on its correct installation in accordance with the tested design and the manufacturer's instructions. This is vital because firestop systems are designed and tested under specific conditions, and their performance is only guaranteed when installed as intended.

When a firestop is properly installed, it effectively seals openings and joints to prevent the spread of fire, smoke, and heat between different areas of a building. The integrity of this system can be compromised if it is not installed according to the prescribed guidelines, leading to potential pathways for fire that the material was meant to block.

While the use of brand-name materials, the installation site location, and the types of penetrants used are important considerations, they do not outweigh the necessity for correct installation. Even the best materials will not perform well if not applied properly, demonstrating that adherence to tested designs and installation instructions is the cornerstone of a successful firestop system.
