Rock wood insulated panels
Should we use the Rock wood insulated panels for our cold storage?
It’s sandwich panels with rock wood foam and two sides steel plate. Normally, panels thickness include: 40mm, 50mm, 80mm, 100mm, 120mm, 150mm, 175mm, 200mm.
The heat conductivity coefficient (U value) of these panels is 0.043W/(MK). While insulated PUR panels is 0.022W/(MK) and PIR panels is 0.019W/(MK). It means that rock wood panels insulation is not as good as PUR panels, nor the PIR panels. So why there are customers who prefer rock rood panels?
The first reason is its excellent fireproofing performance. Only rock wood insulation panels could reach to A2 fireproofing. While PUR panels could only reach to B2, PIR 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 using rock wood.
In one of our tests, these panels could bear 1000 degree C fire, lasting 1 hour at least.
The second reason is its insulation won’t decrease. As long as the outside steel casing stays in good condition, its insulation could last 30 years.
