It’s sandwich panels with rock wool and two sides steel plate. Normally, rock wool sandwich panels’ thickness include: 50mm, 75mm, 100mm, 150mm, 200mm.

Heat conductivity coefficient (U value) of these panels is 0.043W/(mk). While insulated PU panels is 0.022W/(mk) and PU panels is 0.019W/(mk). It means that rock wool panels insulation is not as good as PU panels, nor the PIR panels. So why there are customers who prefer rock wool sandwich panels?

First reason is its excellent fireproofing performance. Only rock wool insulation panels could reach to A2 fireproofing. While PUR panels could only reach to B2, PU panels could only reach to B1. For some specific cold room or some processing room, some building, fireproofing is very important while insulation is not so important. Then we should consider to use rock wool.

In one of our test, these panels could bear 1000 degree C fire, lasting 1 hour at least.

Second reason is its insulation won’t decrease. As long as the outside steel casing stay in good condition, its insulation could last 30 years.
