Fire Barrier Composite Sheet 36 x 36 In

The 3M CS-195 is a silver firestop panel designed for commercial buildings. It addresses floor and wall penetrations where fire-rated barriers are required. Installers can anchor it with common tools and cut it to fit irregular shapes on site.

Four Hour Fire Rating Intumescent Performance

The sheet provides a 4 hour fire rating through intumescent material that expands under heat. This passive system operates without power draw or moving parts, so it adds no noise or thermal load to the building services.

Commercial Penetration Seal For Floors And Walls

The 3 foot by 3 foot panel covers standard penetration openings in commercial construction. It frees up design flexibility by allowing custom cuts around pipes, conduits and ducts while maintaining the required fire resistance.

Questions about this item

How do you install the 3M CS-195 composite sheet on a wall penetration?

Anchor the 36 by 36 inch silver sheet to the wall with common mechanical fasteners; the step people miss is sealing every cut edge and overlap with approved firestop sealant so the four-hour rating holds.

What maintenance or replacement will the 3M CS-195 sheet need after a fire event?

The intumescent material expands once during fire exposure and cannot be reused; inspect the 36 by 36 inch panel after any heat event and replace it if charring or delamination is visible.

What is the first limit that appears when the 3M CS-195 sheet is exposed to sustained fire?

The assembly maintains its fire barrier integrity for four hours; beyond that duration the intumescent layer is exhausted and the penetration can no longer be considered protected.
