Which Type of Insulation to Choose?
Popular insulation options include PU foam, PIR foam, rock wool, EPS, and XPS. Choose based on your needs in thermal insulation, fire rating, cost, and rigidity. For constructing clean rooms, rock wool panels are recommended due to their non-combustible nature and excellent fire behavior.
Is Rock Wool Panel Good for Soundproofing?
Yes, rock wool panels provide excellent soundproofing. They are durable, maintain performance over time, and can handle sounds over a wide frequency range. For better sound insulation, consider 100mm thick rock wool or mineral wool, made of stone.
Is Rock Wool Panel Expensive?
Compared to PUR/PIR sandwich panels, rock wool panels are economical. For instance, a 50mm rock wool panel with 0.4mm PE paint steel surface costs around $13.
Is Rock Wool Insulation Dangerous?
Rock wool is safe to breathe, though it can be itchy if touched directly. Zonsteel panels are sealed with steel to significantly reduce rock wool particles, and holes for switches, lights, or equipment are covered with channels.
How Do You Make Rock Wool Panel?
High-quality rock wool sandwich panels result from a good production line, sound production processes, and systems. Zonsteel’s process includes attaching protective film, steel coil preheating, rock wool cutting, misaligned docking, glue spraying, double track curing, and custom cutting and packing. This ensures flatness, bonding strength, and minimal thickness tolerance.
How Thick Should Rockwool Be?
