1. What is Rockwool?
Rockwool is a stone-based insulation.
It is sourced from abundant lava deposits of volcanic rocks which are melted in
a cupola furnace like a controlled man-made volcano. As the re-melted lava comes
out of the furnace, it is spun, given water repellency treatment and bound
together in a wool-like fleece. Rockwool is a stone wool, which is inorganic and
ideal for thermal insulation, fire protection, acoustic control and
environmental purposes. During the manufacturing process, Rockwool is cut,
shaped and combined into many different products for a wide variety of
applications including buildings, systems, services, marine and offshore.
2. What density is Rockwool?
There is no single answer to this.
Rockwool products are destined for a wide variety of applications needing
different densities, each of which is designed into the product at the
manufacturing stage. The most familiar Rockwool product will be Rockwool
Rollbatt, a light density 24 kilogram per cubic meter (kg/m3)
material used typically for loft insulation. At the other end of the density
range is a system for cladding buildings using a high density panel of
compressed Rockwool at over 1000 kg/m3. The versatile range of
Rockwool products includes rolls, slabs, boards, dual density systems, mats,
pipes, fabricated and loose wools, all of which are provided in a range of
densities and thicknesses suitable for their best application.
