Technical References
Timloc loft access doors comply with current Building Regulations relating to the conservation of fuel and power, including Approved Documents L1A and L2A (2013 and 2006 editions).
Tested to exceed regulatory requirements, the loft hatch has demonstrated zero air leakage (0.00m³/(h·m²)) at a positive pressure of 50Pa, supporting compliance with Building Regulation Part L and BS5250:2011 for the control of condensation in buildings.
The insulated door panel incorporates polystyrene insulation with a thermal conductivity of 0.038 W/mK. When calculating overall ceiling U-values, a correction factor of 0.004 W/m²K should be applied. Ceiling U-values should not exceed 0.16 W/m²K in line with current guidance.
Timloc loft hatches are manufactured without the use of urea formaldehyde, CFCs, HCFCs, or HFAs. The products have zero ozone depletion potential and a Global Warming Potential (GWP) of less than 5.

What is a drop down loft hatch?
A drop down loft hatch is a ceiling access door with a hinged panel that opens downward, allowing easy entry into the loft space. Unlike push-up hatches, the door remains attached to the frame, making it safer and more convenient to operate. Many drop down loft hatches are designed to work with loft ladders and include seals or insulation to help reduce air leakage.
What size opening do I need for a loft hatch?
The required opening size depends on the hatch you choose, but most standard drop down loft hatches fit a structural opening of around 562 x 662mm. It’s important to check both the frame fitting size and the clear opening size to ensure safe and practical access. If you plan to install a loft ladder or regularly use the loft for storage, a larger opening may be more suitable.
Do I need insulation in a loft hatch?
Yes, insulation in a loft hatch is important for maintaining energy efficiency and meeting UK Building Regulations. An insulated loft hatch helps reduce heat loss and prevents draughts between the loft and living space. Lower U-values indicate better thermal performance, so choosing a well-insulated hatch can contribute to improved overall energy efficiency in your home.
