For Walls

  • Polypropylene string
  • Staple gun and staples

Installing wall insulation in timber framed construction

  • Ensure you place a warning tag to prevent power being restored prior to completion of the install. Be aware that your electrical appliances will not operate during this time.
  • Friction fit Bradford wall insulation in wall cavities.
  • For external walls, stringing is recommended when installing Bradford Gold wall insulation to ensure the insulation cannot bridge the cavity.
  • Start at the underside of the top plate, 75mm in from the vertical stud.
  • Staple polypropylene string to the underside of the top plate as far back as the thickness of the insulation.
  • Drop the string to the top of the nogging, tensioning before stapling.
