Rock Wool


ROCKWOOL RWA45 has been developed for thermal, acoustic and fire performance in a range of construction types. RWA45 is made up of high-quality resin bonded slabs in a variety of thicknesses and densities. Specialist facings are available to order to meet the specifications of unique projects.

The ROCKWOOL slabs can be applied to an array of general building applications for acoustic and thermal insulation of partition walls, ceilings, floors and roofs. The multi-use solution is well suited for easy application throughout constructions.

RWA45 is rated Euroclass A1 non-combustible, providing the highest level of fire performance. Using RWA45 in ceilings, walls and floors can help to compartmentalise rooms, reducing fire spread and damage. 

RWA45 insulation slabs achieve Lambda 0.035 W/mK and are available in seven standard thicknesses from 25-100mm, with a density of 45 kg/m3.

Accreditations: 

Euroclass A1 Non-combustible

  • ROCKWOOL RWA45 Insulation Slabs offer excellent thermal, acoustic and fire performance.
  • The slabs are easy to handle and install.
  • Rated Euroclass A1 non-combustible, RWA45 offers the highest level of fire resistance.
  • RWA45 is a durable insulation solution which will maintain high performance over the lifetime of the building. 
  • The water repellent qualities of the insulation prevent moisture build up, damp and rot.

Rockwool insulation refers to a type of insulation that is made from actual rocks and minerals. It also goes by the names of stone wool insulation, mineral wool insulation, or slag wool insulation. A wide range of products can be made from Rockwool, due to its excellent ability to block sound and heat.Rockwool insulation is commonly used in building construction, industrial plants, and in automotive applications. 

To manufacture Rockwool, minerals and other raw materials are heated to about 2910°F (about 1600°C) in a furnace, through which a current of air or steam is blown. More advanced production techniques are based on rotating the molten rock at high speeds in a spinning wheel, in some ways resembling the way cotton candy is made. The finished product is a mass of very fine intertwined fibers, bound together with starch. Oil is also added during production to decrease the formation of dust.

The individual fibers of Rockwool Insulation are good conductors of heat on their own, but rolls and sheets of this insulation are highly efficient at blocking the transfer of heat. They are often used to prevent the spread of fire in buildings, due to their extreme high melting point. Rockwool used in insulation plays a significant in reducing the energy comsumed in both domestic and commercial sectors.
