How will the insulation performance of Rockwool Sandwich Panel change in high or low temperature environments?

Rockwool Sandwich Panel is mainly composed of rock wool core material and two layers of metal panels (such as steel plate or aluminum plate). Rock wool is a high-quality insulation material with excellent thermal insulation properties and low thermal conductivity. In high or low temperature environments, the insulation performance of Rockwool Sandwich Panel will have different performances, but overall, its performance is relatively stable.
High temperature environment:
The melting point of rock wool is relatively high, usually over 1000°C, so in high temperature environments, the rock wool core material will not melt or undergo significant thermal deformation, thus maintaining its thermal insulation properties.
The metal panel of Rockwool Sandwich Panel can also withstand higher temperatures, but prolonged high temperatures may cause thermal expansion or oxidation of the metal. However, this change usually does not have a significant impact on the insulation properties of the rockwool core.
Under extreme high temperatures, although the thermal insulation performance of rock wool is still good, the sealing performance of the overall structure and the strength of the connections may be affected, so the stability and safety of the structure need to be paid attention to.
Low temperature environment:
The thermal conductivity of rock wool is low, so in low temperature environments, Rockwool Sandwich Panel can effectively reduce heat transfer and keep the room warm.
Low temperature usually does not have a significant impact on metal panels, so low temperature environments have little impact on the insulation performance of Rockwool Sandwich Panel.
However, at extremely low temperatures, metal panels may undergo cold shrinkage, which may cause the gaps between the panels to increase, thereby affecting the insulation effect. But this usually occurs under extreme cold conditions and has relatively little impact.
In general, Rockwool Sandwich Panel shows good thermal insulation performance in both high and low temperature environments. However, in practical applications, other factors need to be considered, such as structural stability, sealing, strength of connectors, etc., to ensure the performance and safety of the overall structure.
