    RockWool Roll Loft Insulation Simple but incredibly effective

      Insulating the loft is one of the most cost effective and efficient ways to improve the energy performance of a home… and reduce utility bills. ROCKWOOL Roll is the ideal loft insulation solution for horizontal loft application. The mineral wool insulation is an all-round high specification option for thermal and acoustic performance, as well as fire resistance.  
      ROCKWOOL Roll is made up of medium density mineral wool insulation. The thermal insulation boasts acoustic properties and is fire resistant, rated A1 Euroclass non-combustible.
      Manufactured at a width of 1200mm, ROCKWOOL Roll -can be cut at either 400mm or 600mm widths with the use of a long-serrated blade. The roll is available in 150mm, 170mm and 220mm thicknesses.
      The insulation solution is suitable for horizontal roof application in all building types, or can be used to as an acoustic absorber in suspended ceilings. ROCKWOOL Roll does not react with any metal components in lofts, nor does it cause loss of plasticiser from PVC cabling and pipes.

    ROCKWOOL Roll considerably enhances thermal performance and sound reduction in roof spaces and ceilings.
        -ROCKWOOL Roll is a multi-purpose product, suitable for numerous applications.
        -The mineral wool insulation provides excellent thermal performance.

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

    Dimensions
    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.

    Installation
    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.
