Twist operated catch to release a downward opening hinged door.

Tested and certified by BRE as meeting Building Regulation Part L’s reasonable air leakage requirements of <10m3/(h.m2) at a pressure differential of 50Pa and BS5250:2011.

Clean, discreet profile with an easy to clean finish. Manufactured from injection moulded polypropylene. Available in a choice of insulation U-value performances of 0.82 W/m2K, 0.35 W/m2K and 0.25 W/m2K.

Uses

• To provide simple, easy access through ceiling into the loft space

Features and Benefits

• *Air permeability measured at 50Pa as 0.00m3 (h.m2) under positive pressure test conditions
• Purpose made product saves time and money compared with traditional joiner-made timber loft access doors
• Independently air leakage tested by BRE
• Excellent aesthetic appearance
• Factory finished and ready to fit straight from the box
• Insulated door panel with integral draught and vapour seal
• Maintenance free, no need to paint
• Hinged design allows use of a telescopic loft ladder
• Acoustic performance of 30dB

Material and Colour

• The door and frame are one piece injection moulded polypropylene.
• Insulation is CFC free expanded polystyrene foam.
• Door and frame available in white only RAL 9010.

Installation Advice

• This product is designed to fit between 38mm thick trussed rafters or ceiling joists spaced at 600mm centres which provide a clear joist opening width of 562mm.
• If the roof design does not provide this joist opening width, a suitable opening must be formed.
• Trimmers must be installed across the ends of the frame. These must be spaced to give a clear opening length of 662mm.
• The frame fixes with ten screws, three through each side and two through each end.
• Fit the loft access door after the ceiling has been plaster boarded and skimmed.
• The frame must be a good fit into the trimmed opening. Never try to force it into an opening that is too small. If the opening is too large use packers to ensure a good fit.

Technical Considerations

• Timloc loft access doors comply with the most recent Building Regulations; ‘THE BUILDING REGULATIONS ‘Conservation of fuel and power’ APPROVED DOCUMENT L1A & L2A (2013 Edition).
• Timloc loft access doors comply with the most recent Building Regulations; ‘THE BUILDING REGULATIONS 2000 ‘Conservation of fuel and power’ APPROVED DOCUMENT L1A & L2A (2006 Edition).
• The Timloc loft access door has demonstrated a zero 0.00m3/(h.m2) air leakage at ‘positive’ 50Pa to exceed requirements set in the Building Regulation Part L1A & L2A while fully complying with BS5250:2011 the Code of Practice for control of condensation in buildings.
• Timloc loft access doors contain polystyrene insulation with a Thermal Conductivity of 0.038W/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 Urea Formaldehyde, CFCs or indeed any of the so-called soft CFCs, i.e.. HCFCs & HFAs. They have an ozone depletion potential of zero and Global Warming Potential of less than 5.
