There is a common misconception that the rockwool LRB mattresses and resin-bonded mattresses are the same and can be used interchangeably. But, it is not the case. Although both are insulation solutions installed in acoustic and high-heat industrial applications, there are some clear differences. Let’s dig deeper into the differences between both insulation mattresses:
| No | Features | Rockwool LRB Mattress | Resin Bonded Mattress(RBM) |
|---|---|---|---|
| 1 | Resin Content | Lightly bonded | Highly bonded |
| 2 | Base Material Used | Rockwool | Rockwool or glasswool |
| 3 | Density | 100–150 kg/m³ | Usually higher |
| 4 | Flexibility | High (compressible) | Low (more rigid) |
| 5 | Temperature Withstanding Capacity | Up to 750°C | In between 230 to 750°C (depending upon the material) |
| 6 | Applications | Pipes, vessels, boilers | Flat surfaces, load-bearing areas |
