Rockwool is a brand leader within the construction and insulation industry due to its solutions within residential and commercial buildings. Rockwool is trusted and well-known among builders, contractors and architects. Rockwool group is world leading manufacturer of stone wool products, made from the earths most natural resources. Rockwools high insulation performance comes from tiny pockets of air trapped among the stone wool fibres. The stone wool products are high sustainable due to their 100% recyclability which allows the products to be transformed into new Rockwool products.
Rockwool History
The Rockwool journey truly began in the 1930s as gravel pits around a small Danish Island as well as a finishing net factory and sand-lime brick factory. In 1935 they discovered a production of mineral wool was possible, using the companies stone deposits for stone wool production. At this time most houses were not insulated or energy efficient and there was a space in the market for stone and rock wool following the production of glass wool around two years prior. By the 1960s Rockwool had adapted and improved its methods to meet product requirements and regulations and was successfully producing stone wool products in over six countries. Rockwool now has factories in 14 countries and representation in over 30 countries.
At the heart of Rockwool’s mission is to help tackle problems facing society today by carrying out scientific research into social and economic issues as well as carrying out practical interventions. Rockwool insulation includes insulation rolls, batts, and slabs and can be installed throughout properties including ceilings, pitched roofs, external walls, internal walls, separating walls and floors, and timber suspended ground floors.
Rockwool RWA45
Rockwool RWA45 slabs are high-quality, cost effective, and reliable and remain at the core of the Rockwool product range. RWA45 slabs have a density of 45kg/m3. The slabs are made up of stone wool, high-quality resin bonded slabs, which makes this product ideal for reducing sound levels, repelling water and moisture, improving thermal quality of the building, and providing the highest levels of fire performance, reducing the potential spread of fire between rooms. The insulation slabs are 1200mm by 600mm and available in thicknesses from 25mm to 120mm. RWA45 has a thermal conductivity of 0.035W/mK and is suitable to be installed within various applications including suspended ceilings, wall steel and timber framing systems, pitched roofs, flat roofs, and floor applications including ground floors, separating floors, and intermediate floors. The slabs are lightweight, flexible and long lasting, these slabs can be installed by friction fitting the slabs into the cavity space.
Buy Rockwool Flexi
Rockwool Flexi is a high-quality and impressive insulation product that improves the buildings thermal conductivity with ease. This product is a multi-purpose slab that will improve the thermal and acoustic performance of the building. It’s flexible edge along one side of the slab means installation is made easy, with the slabs designed for a friction fit application between metal and timber frames ensuring a tight fit. A safe option for design specifications and building regulations. The Flexi slabs are 1200mm by 600mm or 1200mm by 400mm available in thicknesses from 50mm to 180mm and made from a type of mineral wool constructed from basalt rock. The Rockwool Flexi is ideal for installation within applications including external walls, internal walls and partitions, pitched roofs, and multiple floor applications within residential and non-residential properties. This material is lightweight, easy to cut and handle, and easy to manipulate when applying. This product has water repellent qualities that can prevent moisture build up, damp, condensation, and rot.
Buy Rockwool RW3
Rockwool RW3 slabs are designed for developed for thermal, acoustic, and fire performance. The boards are generally applied in ceilings, walls, roofs, and floors within home and work spaces, preventing fire, noise, and temperature levels from travelling between rooms. The RW3 slabs are 1200mm by 600mm with a square edge available in thicknesses from 25mm to 100mm. RW slabs are made up of high-quality resin bonded slabs of rock wool and will last for as long as the building does, and product performance will not reduce over time. RW3 slabs have a density of 60kg/m3 and a thermal conductivity of just 0.034W/mK. This product will reduce the air flow moving throughout the building. This product can help to reduce energy waste within residential and commercial buildings as well as ships and offshore platforms and will help to create a more energy efficient environment. These slabs are packaged tightly compressed and are easy to transport and handle.
Buy Rockwool RW5
Rockwool RW5 is a slab of acoustic insulation that is durable and long lasting whilst improving the thermal quality of the building. RW5 are 600mm by 1200mm with thicknesses available from 25mm to 150mm and a density of 100kg/m3. This product is high-quality and can be applied throughout the buildings thermal envelop including suspended ceilings, walls within timber and steel framing systems, ground floors, separating floors, and intermediate floors, as well as pitched and flat roofs. These applications will reduce heat and sound levels travelling throughout the building, the slabs can be doubled up if required to reach unusual thicknesses. This product has fire reducing qualities with a fire rating of Euroclass A1 non-combustible, and will not ignite or smoke, providing extra protection in the event of a fire within houses and buildings, RW5 can help to meet building regulations and requirements. Not only does it provide fire protection, but these slabs also repel water, reduce noise levels, require no maintenance and are cost-effective.
Rockwool FAQs
What is Rockwool made of?
Rockwool insulation is a rock-based mineral fibre insulation made up of basalt rock and recycled slag. Basalt rock is a volcanic rock and slag is a by-product of the steel industry. These minerals are melted and spun into fibres to form rolls, batts, and slabs.
Can you touch Rockwool products?
When skin comes into contact with rockwool fibres, it can cause temporary itching. This can uncomfortable but is not harmful. It is recommended that protective clothing such as gloves and long sleeves are worn before handling and touching rockwool products to avoid irritation.
What is the difference between the Rockwool products within the RW range?
Each Rockwool RW slab is made up of the same material and is often available in the same sizes and thicknesses, or they can be doubled up to meet a required thickness. The main difference in the slabs is the density of each product. For example, RW4 slabs have a density of 80kg/m3 and RW5 slabs have a density of 100kg/m3. Please consult your builder or architect if you are unsure of the density you require for your project.
What is the difference between stone wool and glass wool?
Stone wall or rock wool is manufactured from deposits of naturally occurring volcanic rock whereas glass wool or fibreglass is manufactured from silica or glass cullet. Both glass wool and rock wool products are also known as mineral wool, which refers to insulation made from minerals such as glass and rock.
What happens if Rockwool insulation gets wet?
Rockwool insulation will not absorb water into the body of the insulation, it will simply drain the water away. The materials are inorganic which means it is rot proof and provides no food source or growth support for funghi, mold, or bacteria.
