They are specifically designed for use in cold lofts, where pitched roofs are insulated at ceiling level. The open-cell nature of these fibreglass insulation rolls traps heated air, using its many tiny spaces, thus effectively reducing heat loss through roofs. Knauf loft Insulation rolls are partially cut rolls that enable easy installations in between joists.
