Installation advice
• The 1160 and 1161 are designed to fit between trussed rafters orceiling joints spaced at 600mm centres which provide a clear
joist opening width of 562mm to be plasterboard lined to give 542mm
• If the joist spacing does not provide this opening width,
 a suitable trimmed opening must be formed
• It is essential that trimmers are installed between the ceiling joists across the ends of the frame
• The frame fixes with 10 screws, six into the ceiling joists at the sides of the frame, and four through the ends of the frame into
 the trimmers
• A 50mm tall by 10mm thick protective plasterboard surround
 is required along all four sides of the trimmed opening

Technical considerations
• Timloc loft access doors contain glass wool insulation with a Thermal Conductivity of 0.037W/mK. For this reason a correction
 U value of 0.004W/m2k should be calculated to the proposed U value figures for a ceiling (U value for a ceiling, not to exceed 0.16W/m2k)
• With reference to insulation, the products in this range do not use, contain or produce CFC's, ie. HCFC's & HFA's. The mineral wool
 insulation relies on entrapped air for its thermal properties; air is not a VOC and it does not have Global Warming Potential (GWP) or Ozone Depletion Potential (ODP).
