3M™ Fire Barrier Plank PK39
Easy to install in large openings
A Better Way to Fill Large Gaps
When sealing larger cavities, use 3M™ Fire Barrier Plank PK39 (PDF, 78 Kb) to restore the integrity of the wall with a simple "stack, seal, and done" application, without the use of special tools. The blocks are engineered to remain securely in place, eliminating traditional wire mesh reinforcements. Pre-formed blocks help technicians fill large openings quickly. The material is easy to trim on site without special tools, achieving a tight, custom fit. No cure time is required, which means installation (PDF, 252 Kb) is completed faster, and the blocks are paintable with primer for a more seamless appearance.

The blocks are fully re-enterable and reusable, saving time and money, while minimizing waste. Once the opening is filled, seal around the perimeter and any penetrating items with 3M™ Fire Barrier Rated Foam FIP 1-Step or other 3M™ fire barrier sealants (sold separately).
