Code: IW4741

Multi-Roll 44 is a lightweight, non-combustible glass mineral wool roll, designed to provide thermal insulation in lofts. This roll is typically used for insulating loft spaces and cold roofs but can also be used in a multitude of different applications.

To help installation, the roll has been perforated to allow it to be split into any of the three commonly required widths, making it easier to manoeuvre into joist spacings and reducing waste and onsite cutting.
