Earthwool Loft Rolls are non-combustible, Glass Mineral Wool rolls, manufactured using revolutiona...Earthwool Loft Rolls are non-combustible, Glass Mineral Wool rolls, manufactured using revolutionary ECOSE Technology, designed for cold lofts where pitched roofs are insulated at ceiling level. Combi-cut products have partially cut perforations, providing flexibility to be used between joists at either 400mm or 600mm centres, or used unsplit as a full-width roll. This insulation is primarily for the thermal insulation of pitched roofs at ceiling level, but can also be used to thermally insulate floors. It is certified A1 non-combustible, offering the highest level of fire performance. The rolls are soft to touch and easier to handle, making it a perfect solution for insulating a cold loft at ceiling level. Knauf Loft Roll Insulation 150mm has a thermal conductivity value of 0.044 W/mK, and comes in 1140mm wide rolls with perforations at 570mm and 380mm centres, allowing it to fit easily between roof rafters or floor joists.

Setup, Compatibility & Care
Preparation: Ensure the loft space is clear of debris and that the joists are accessible.
Measurement: Measure the space between the joists to determine the required width and length of the insulation.
Cutting: Use a sharp knife to cut the insulation to the required size, using the perforations as a guide where appropriate.
Installation: Place the insulation between the joists, ensuring it fits snugly without being compressed. For a good fit, aim to cover any gaps. Ensure that the insulation is installed at the ceiling level.
Compatibility: Knauf Loft Roll 44 is compatible with most common building materials and is suitable for use in both new and existing buildings. Make sure the structure is sound and free of damp.
Care: Avoid compressing the insulation as it can reduce its thermal performance. Keep it dry to maintain its effectiveness. In case of any damage, replace the affected area.
