Manthorpe GL250 Loft hatch Access Door

The GL250 drop down loft door is an innovative solution to the need for energy efficient loft space access, offering a cost effective alternative to traditional roof space access. The unobtrusive design coupled with sleek, contemporary styling makes the door an ideal match for modern decors.


The revolutionary design of the multi-point catch mechanism means that the GL250 door can maintain a more effective draught seal around the entire accessible opening, helping to meet the air leakage requirements of Part L of the Building Regulations and preventing the problem of moist warm air entering the roof space causing condensation and heat loss issues.

Environmental & Air Leakage Assessment

The expanded polystyrene insulation used in the GL250 has a Global Warming Potential (GWP) of less than 5 and is CFC/HCFC-free with an Ozone Depletion Potential (ODP) of zero

The GL250 drop down loft access door has been independently air leakage tested by the BRE to the requirements for a “Well Sealed Ceiling” as outlined in BS 5250, meeting the recommend leakage rate of <1m³ at a pressure differential of 2 Pa, and the Building Regulations Part L2A ‘reasonable limit’ for the design air permeability of buildings of 10m³/h.m² at 50Pa
