100mm Rockwool RWA45 Insulation Slab (Prorox SL920) is a semi rigid non-combustible resin bonded fire resistant acoustic insulation slab designed for use in floors, roofs at rafter level, partitions, ceilings, steel and timber frame walls.
Using RWA45 Acoustic Insulation in ceilings, walls and floors can help to sectionalize rooms, reducing fire spread and damage (Class ‘0’ Building Regulations) for both new build and refurbishment projects.
Rockwool RWA45 100mm x 600mm x 1200mm is an unfaced, odourless, non-hygroscopic stone wool insulation slab with a certified thermal conductivity of 0.035W/mK.
These thermal and acoustic insulation slabs are free of CFCs and HCFCs and will not encourage the growth of fungi, mould or bacteria.
Rockwool stone wool products work 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 acoustic slabs make them ideal for use as a sound absorber with water repellent qualities of the insulation preventing moisture build up, damp and rot.
RWA45 Slab is a long-lasting insulation material made from renewable resources which will maintain high performance over the lifetime of the building (ODP and GWP free).
Thermal and acoustic slabs are easy to cut and shape with a large bladed knife or saw.
Rockwool RWA45 insulation slabs are made from natural, sustainable and recyclable resources.

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.
