Board Rock Wool Core Material
Products Description
Sandwich panel rock wool core material through bonding and metal face composite, this vertical fibre structure makes the sandwich panel has high compressive, high shear and tensile strength characteristics, can be widely used in multi-modelling of the metal panel of the core core material, such as ultra-large-span or high-level applications such as building façade, walls, roofing, partitions, ceilings, and high load sandwich panels, as well as the fire door industry, and so on. The products can be supplied in pre-cut form, cut into strips (core slats), with the fibres applied vertically to increase the fibre's peeling strength; they can also be supplied in the form of full panels of general specifications for customers with cutting equipment, which can be cut and then turned over for use by the customer (rockwool core panels).

FAQ
Q: What is rock wool sandwich panel?
A: Rock wool sandwich panel is a kind of sandwich panel made of rock wool as core material and colour coated board or aluminium board as surface material by pressing and composite.
Q: Do you accept OEM?
A: Yes, we can do OEM.
Q: How long is the delivery time?
A: The delivery time usually depends on the order quantity, usually around 10-20 days.
Q: What is the thermal conductivity of rock wool sandwich panel?
A: The thermal conductivity of rock wool sandwich panel is related to the diameter and direction of the fibres and the density of the rock wool, the lower the thermal conductivity, the better the heat preservation effect.
