Welcome to Online Insulation, one of the leading sources for insulation solutions at world-class prices. Within our range, we stock some of the most reputable names so that we can guarantee the very best results possible, with a few of the most notable brands including Knauf Earthwool, Celotex and Rockwool insulation. For further details about our business and intentions, be sure to visit our ‘about us’ page when you have the chance. 


For additional background knowledge, Rockwool insulation is one of the most reputable insulation solutions due to its use of two key materials, wool and molten rock. Not only is this combination highly thermal efficient, but Rockwool also offers noise protection due to the increase in density and random fibre standard orientation. This is in addition to increased fire protection due to the rock components that are fire-resistant.  


Due to these factors, we stock Rockwool insulation solutions, where we have a wide variation of their products available on our website. These all vary in width, dimension and the different style of insulation, with each type of insulation providing their own uses and advantages. For example, the 100mm Cavity Batt is a full-fill insulation solution to masonry cavity wall construction, which is why it’s favoured for new builds and extensions. This differentiates from Rockwool RWA45 which is a semi-rigid slab used for thermal, acoustic and fire insulation in general building applications.
