Just one layer improves your building’s energy efficiency and performance. Tested and approved for multiple low-slope roof assemblies, ROCKWOOL MULTIFIX™ reduces the number of layers required while improving the performance of your entire assembly. Fast and easy to use, it’s fewer steps to get a good job done.
Minimal change in thermal performance, increased thermal mass and increased dimensional stability allow for reduced gaps, increased energy efficiency and the potential for longer-lasting roofs.
A melting point of up to 2150°F (1177°C) means ROCKWOOL MULTIFIX™ will not develop smoke or spread flames when exposed to fire. Only stone wool products are FM 4470 – Non-Combustible Core rated.
Combining the non-directional fiber structure of ROCKWOOL MULTIFIX™ with increased mass allows for sound reduction and more comfortable occupants.
Ready to use with both hot- and cold-adhered roofing systems. |
| ROCKWOOL MULTIFIX™ is the first stone wool insulation product with a built-in coverboard and a mineral-coated fiberglass facer that is compatible with multiple attachment methods. It can be used as a roof insulation or insulating coverboard over other insulations. In these cases, it improves performance by regulating the temperature of the thermal insulation, particularly in cold temperatures. |
ROCKWOOL MULTIFIX™ is denser than conventional insulation – effectively reducing sound transmissions and creating more comfortable environments.
The exceptional stability of ROCKWOOL MULTIFIX™ reduces gaps, system movements and stresses, potentially increasing the longevity of your roof.
Our products are diverse and contribute to shaping a circular economy, enhancing resource efficiency, and nurturing the safety, health and wellbeing of people.
