Rockwool Building Slabs
Standard Rockwool Product, generally readily available in most thickness’s at the lower densities such as 45kg/m² and 60kg/m². As the slab densities increase, and product popularity declines, short lead times will apply.
The Rockwool RW Slab Range is used for thermal, acoustic and fire insulation in general building applications, certified to EN 13162.
These slabs are particularly suitable for acoustic infills in partitions and ceilings, providing a high level of control of both airborne and structure-borne sound. They are also suitable for acoustic absorption in the linings of buildings.
Rockwool Building Slabs are a range of rigid and semi-rigid, resilient, non-combustible rock mineral wool slabs,available in densities from 33 to 140kg/m . The standard products are supplied un-faced, but they can also be manufactured with a factory applied foil or tissue facing, they are also available in a water repellent grade.
The product range consists of high quality resin bonded slabs in a variety of thicknesses and densities.
Mineral slabs of a density of 45 kg/m³ have now become the de-facto standard for normal domestic insulation purposes. Densities above this level are particularly good for use in sound studios and commercial and industrial areas where, for example, machine noise is prevalent.
Availability: These products are popular, and are generally readily available. Heavier densities may have lead-time requirements. Please review the availability indicators.
Additional Options: RW slabs are also available with number of facing options, which are:
- Non-woven mineral black tissue (75gsm)
- Non-woven mineral white tissue (100gsm)
- Aluminium foil
These options need to be priced on application, and need to achieve realistic economies of scale. Therefore, minimum order sizes will apply
Excellent thermal, acoustic and fire insulation
Suitable for a wide range of general building applications
Euroclass A1 to BS EN 13501-1
Easy to handle and install
Black or white tissue and aluminium foil facings available
Rockwool continues to work throughout the lifetime of the building. As well as reducing the heat needed to keep buildings warm in winter, stone wool insulation also maintains a cool interior temperature in summer. It’s energy efficient as well as being environmentally friendly all year round
All Rockwool RW slab products, either un-faced or with an aluminium foil or glass fleece on one or both surfaces, achieve an A1 classification in accordance
with BS EN 13501-1 and therefore comply with the requirements of non-combustible materials/products, as defined in all UK and Ireland Building Regulations.
Rockwool RW Slabs are highly water repellent and non-hygroscopic
For general building applications (Lambda 90:90)
at temperature 10 degrees C:
Rockwool RWA45 slab = 0.035 W/mK | Rockwool RW3 slab = 0.034 W/mK | Rockwool RW5 slab = 0.034 W/mK
Handling and Storage
Rockwool RW slabs are light and easy to cut to any shape with a sharp knife. They are shrink wrapped in polyethylene and supplied on pallets which are shrouded with a waterproof hood suitable for outside storage.
All standard un-faced slabs are manufactured 1200 x 600mm. All foil faced and tissue faced slabs are manufactured 1000 x 600mm. The standard thickness range of Rockwool RW slabs are shown in the table below.
* Denotes thickness also available as ‘standard’ with white or black tissue facing (not foil facing). All foil faced and tissue faced slabs (other than shown above) are non -standard and will be subject to minimum order quantities.
