Rockwool Fibers are Inorganic and Composed Mainly of Silica and Slumina

Rockwool slabs conforming to ASTM C-612 and equivalent BS-3958 Part 5 are designed for thermal and acoustic insulation of flat or slightly curved surfaces. These slabs are produced from long, non-combustible resin bonded fibers. They are easy to cut, fit and handle. The robust fibers in the slabs combine high levels of thermal efficiency and acoustic absorption.


Designed for a wide range of applications at both high and low service temperatures. It can be used on both flat and slightly curved surfaces for thermal and acoustic insulation. They are also suitable for thermal insulation of ducts, tanks, large vessels, cavity walls, curtain walls and sandwich panels.

Service Temperature

Plain Rockwool Insulation has a service temperature of 780°C when tested in accordance with DIN 52271 for 80mm thickness and 100 kg/m3 density. However there is possible deviation for lower densities, and with facings. The user is advised that it is possible that the maximum use temperature of facings and adhesives is lower than the maximum use temperature of the insulation. The user shall ensure that sufficient thickness shall be installed so none of these accessory items (facings and adhesives) are exposed to temperatures above their maximum use temperature.

Standard Delivery

Available in standard width of 600 mm and length of 1200 mm.
Other sizes are available upon request.
