30mm Rockwool RWA45 Insulation Slab Black Tissue Faced is a semi-rigid, 45kg density non-combustible fire resistant resin bonded stone wool insulation slab, used for structural elements such as concrete car park soffits.
Rockwool RWA45 Insulation Slab 30mm x 600mm x 1200mm faced with black tissue on 1 side can provide from 30 minutes up to 240 minutes fire protection to the underside of concrete soffits.
Black Tissue Faced Rockwool RWA45 is a standard density (45kg per cubic meter) semi-rigid insulation slab with a certified thermal conductivity (lambda value) of 0.035W/mK.
These fire, thermal and acoustic RWA45 black tissue faced insulation slabs are free of CFCs and HCFCs and will not encourage the growth of fungi, mould or bacteria.
Rockwool works in two distinct ways to reduce noise, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.
The structure of the fibres in RWA45 insulation slabs make them ideal for use as a sound absorber with water repellent qualities of the insulation preventing moisture build up, damp and rot.
Rockwool RWA45 Black Tissue Faced is a robust long-lasting insulation made from renewable resources which will maintain high performance over the lifetime of the building.
RWA45 Black Tissue Slab works in two ways to reduce noise, either by absorption of sound at the surface or inhibiting its transmission.
The absorption coefficient achieved will vary according to thickness and density of the slab and application.
The black tissue facing helps to avoid the slab edges from showing as shadows through the perforated inner sheet and assists in preventing fibre migration.

Black Tissue Faced Rockwool RWA45 Fixing and Application:
· When fixing a tile or modular system, it is advisable to start with a focus reference slab in the centre of the soffit with subsequent slabs being fixed working towards each edge.
· The use of string lines or laser alignment equipment will assist in ensuring alignment and squareness of the installation.
· If installed into concrete or steel composite deck, a pilot hold should first be drilled prior to the fixing being screwed into place.
· Soffit Slabs should be fixed directly to the concrete soffit using Ejot DDS fixings with the Ejot DDT70 washer or similar.
· Care should be taken not to over-tighten fixings to prevent damage to the slab surface.
· For further information on fixing type and suitability for the substrate, please refer to the fixing manufacturer.
· It is recommended that all board joints should be staggered and tightly butt jointed.
· Soffit insulation products should not be used for supporting light fittings or services.
· Such installations should be supported from the concrete soffit.
· Where penetrations occur, the boards should be cut locally to ensure a tight fit around the penetration.
· Slabs can be cut slightly oversized to ensure a tight fit under slight compression around the penetration.
· Any small gaps that result from cutting can be infilled using the Acoustic Intumescent Sealant.
Black Tissue Faced RWA45 Health and Safety:
· The safety of Rockwool stone wool is confirmed by current UK and Republic of Ireland health & safety regulations.
· Rockwool fibres are not classified as a possible human carcinogen.
· The mechanical effect of fibres in contact with skin may cause temporary itching.
· Cover exposed skin during handling and installation.
· When working in an unventilated area, wear a disposable face mask.
· Clean working area using vacuum equipment.
· Waste should be disposed of according to local regulations.
· Rinse in cold water before washing.
· Ventilate the working area if possible.
· Wear goggles when working overhead.

We can help to calculate price per m2 or linear meter (one meter in length) cost, please just contact us via phone 02081910776, email or live chat. Alternatively, you can work it out yourself quickly and easily: to get cost per meter square please divide price shown in orange area by ''Required area (m2)'' Example price of £28.80 divided by board coverage 2.88m2 = cost of £10.00 per m2.
INSTALLERS
No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.
4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER
1. Thermal inspection picture in portfolio
It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.
2. Reviews
Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.
3. Compare prices
Comparing prices will also ensure companies can’t take advantage of you and give you a fair price.
4. Word of Mouth
The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.
Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
