Earthwool Loft Rolls are non-combustible, Glass Mineral Wool rolls, manufactured using our revolutionary ECOSE® Technology, and are designed specifically for use in cold lofts where pitched roofs are insulated at ceiling level. Combi-cut products have partially cut perforations, providing the flexibility to be used between joists at either 400mm or 600mm centres,or used unsplit as a full-width roll.
Ready-cut products are fully cut, and are designed to be used between joists at 600mm centres. Earthwool Loft Roll 44 has a thermal conductivity of 0.044 W/mK. Earthwool Loft Roll 44 is primarily used for the thermal insulation of pitched roofs at ceiling level, it can also be used to thermally insulate floors. When used at ceiling level it is usually laid in two layers, with the first layer between the joists and the second layer over, and at right angles to the joists.
