One side fire wall penetration
8 Sep Photo 2 shows the other side of one of the many firewalls in this building. Even though one side of the wall may be protected properly at each.
Penetration Firestop Systems
With Hilti firestop solutions, you'll benefit from decades of design experience and . It allows for easy re-penetration or cable mining from one side of the wall.
Description:Electrical cables, data cables, and plumbing pipes are few of the items that pass through walls as they travel through a building. Fire resistive joint systems are generally tested to meet UL This is an important joint because the wall system requires a wider space than other wall systems and there could be significant movement in the joint, which could allow fire and smoke to pass through easily. Firestop FT-Rating Many firestopping systems are tested for both thermal and flame resistance. The FT-Rating is the number of hours that a system will prevent the passage of flame as well as preventing a degree-Fahrenheit temperature rise — it will always be the lesser of the F and T Ratings.
