Attic Floor Installation Procedure

  • 1. Clearing

    Clearing the loft area of all debris, insulation, struts and temporary boards to expose the ceiling boards

  • 2. Trimming Joints

    Trimmer Joists form the periphery of the new floor. The strong timbers (approx 225mm x 75mm timber) are secured to the wall plates (brickwork) and bolted to the walls (party walls and around chimney breasts) to form a stable edge to the frame. They must be precisely level and at a height that allows the new joists to fit above or around the ceiling joists. Around the stairwell and below partitions the joists are doubled up. Metal joist hangers are fixed to these depending on the floor plan at approximately 20mm above ceiling to allow for deflection.

  • 3. Spacer Noggins

    Spacer noggins (solid struts) are installed between joists to reduce joist deflection, vibration, improve floor rigidity and performance.


  • 4. Ceiling Joists

    Ceiling joists are tied to the floor joists with steel straps to stabilise the ceiling.

  • 5. Insulation

    Under floor insulation (100mm mineral wool) is installed tightly into joist spacings.

  • 6. Electrical

    Electricians 'first fix' - for laying of electric power and other cables in place from consumer unit up to the ceiling according to the building plans. Positioning cables for sockets, light fittings, control units, shower point, window controls, Internet, phone, TV cable or communications.


  • 7. Plumbing

    Plumbers 'first fix' that identifies radiator positioning and existing flow pipes and the position pipes through floor for radiator supply. Position and fit inflow and outflows e.g. for en suite shower and sanitary ware.

  • 8. Floorboards

    Floorboards are laid over the joists. Moisture resistant, tongue and groove flooring is installed as a base flooring material. Carpets or hardwood flooring requires good quality underlay to reduce impact noise to the rooms below.
