Knauf Insulation Loft Roll 40 is a glass mineral wool roll, designed for use in cold lofts where pitched roofs are insulated at ceiling level, that offers the best thermal performance in the range.
For the thermal insulation of cold pitched roofs at ceiling level. They are usually laid in two layers, with the first layer between the joists and the second layer over, and at right angles to the joists.
A glass mineral wool roll, designed for use in cold lofts where pitched roofs are insulated at ceiling level, that offers the best thermal performance in the range.
It is non-combustible insulation with the best possible Euroclass A1 reaction to fire classification, and is manufactured using the manufacturer's exclusive bio-based binder, ECOSE® Technology.
Features and benefits:
Available as partially cut rolls for use with:
Odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.
Standards and certification:
Manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management systems, as certified by TÜV Nord.

the product that are on the red list - including formaldehyde or phenol.
Glass and rock mineral Wool are easier to install correctly than other insulants such as rigid boards because they adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
Loft Rolls contain no ozone-depleting substances or greenhouse gases. For further environmental information consult the relevant Environmental Product Declaration (EPD), available on the manufacturer's website.
Handling and storage:
Easy to handle and install, being lightweight and easily cut to size, where necessary. Rolls are supplied in recyclable polythene packs (4-LDPE) which are designed for short term protection only.
