    -Fire classification All ROCKWOOL Roll products achieve a reaction to fire classification of A1 as defined in BS EN 13501-1.

    Loft insulation - U-values To comply with Building Regulations Part L: 2013 new pitched roofs with loft spaces need to achieve U-values of between 0.16 and 0.11 W/m²K. The table below shows different approaches to achieve a range of u-values in a loft application.


    Water tanks: Insulation should not be placed directly under cold water tanks. Where access is required to water tanks etc, supports should be provided for a raised walkway
    Loft hatches: To preserve the continuity of insulation, loft hatch covers should be insulated with a minimum 100mm thickness of ROCKWOOL Roll. Double-sided adhesive tape may be used to hold the insulation in place
    Electrical Cables: The IEE Wiring Regulations, 17th edition and British Standard BS 7671: 2008 provide guidance on the correction factors to be applied in down-rating cables according to the situation
    Each case should be separately assessed. Where possible, all cables should be lifted free of the insulation
    -To meet this thermal performance and minimise heat loss through the timbers, ROCKWOOL Roll, Twin Roll or Rollbatt should be cross-layered between and over the ceiling joists.
    -The first layer (generally of 100 mm thickness) is rolled between the ceiling joists, which are normally spaced at 400mm or 600mm centres.
    -A second layer of ROCKWOOL Roll/Rollbatt (e.g. 170 and 220mm thick) or Twin Roll (200mm thick) is then cross-layered to cover the first layer of insulation and the ceiling joists.
