70mm Knauf Rocksilk Flexible Insulation Slab is a thermal and acoustic multi-purpose rock mineral wool insulation slab which can be used to insulate a wide range of applications on site such as timber and metal stud partitions, timber frame walls and suspended timber floors.
Knauf Flexible is non-combustible insulation slab with Euroclass A1 reaction to fire classification, and is manufactured in ECOSE Technology.
Rocksilk Knauf is Flexible on all four sides for quick and simple installation process as well as the fire protection of a loft conversion floor.
Flexible Slab has been tested to provide 60 minutes fire protection when a loft is upgraded into habitable accommodation.
Knauf Rocksilk Flexible Slab is highly durable, odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria.
Flexible Slab will have a life equivalent to that of the structure in which it is incorporated.
Knauf Glass and Rock Mineral Wool are easier to install correctly than other insulation materials such as rigid boards.
Rocksilk Insulation Slabs adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps (thermal bridging).
The absence of air gaps is crucial to achieving a high level of performance in the relevant application.

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.
