Certificate type
A glass mineral wool insulation roll, designed for insulating cold pitched roofs at ceiling level.
Loft Rolls are used 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.
Knauf Insulation Loft Roll 40 is a glass mineral wool insulation roll, designed for insulating cold pitched roofs at ceiling level, with a thermal conductivity of 0.040 W/mK it offers the best thermal performance in the range. It is non-combustible, achieving the best possible Euroclass A1 reaction to fire classification and is manufactured using Knauf Insulation's unique bio-based binder, ECOSE® Technology.
