200mm Knauf Earthwool Loft Roll 44 Combi-Cut Class A1 is a flexible non-combustible glass mineral wool used for insulation between and over the joists in cold lofts where pitched roofs are insulated at ceiling level.

Knauf Glass Mineral Wool 200mm is easier to install correctly than other insulation materials such as PIR rigid insulation boards.

Insulation Rolls adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps (reduceed thermal bridging).

The absence of air gaps is crucial to achieving high level of performance in the relevant application.

Knauf Insulation Loft Rolls are flexible, odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Usually laid in two layers, with the first layer between the joists and the second layer over, and at right angles to the joists.

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.


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.
