GL250-03 | MANTHORPE GL250 03 | 250 03 LOFT DOOR

The GL250-03 Drop Down Loft Access Door provides an unobtrusive and cost effective alternative to
traditional loft space access. The door has a twist action, three point closing mechanism along with a
unique hinge system, allowing the door to be hinged down or be removed from the frame completely for unobstructed access into the roof space.

Draught seals are located to seal between both the frame and the ceiling and the door and the frame. These prevent the problem of moist warm air entering the roof space and meet the air leakage requirements of Part L of the building regulations. The product is also supplied with 50mm of expanded
polystyrene insulation to thermally insulate the back of the door.

The door and frame is stylish yet unobtrusive which has been designed to fit in with almost all house
decor styles. With a lightly textured white finish the door can be easily cleaned with a solvent free damp
cloth, or alternatively the GL250-03 can be painted to match the décor.

Environmental & Air Leakage Assessment

The expanded polystyrene insulation used in the GL250-03 has a Global Warming Potential (GWP) of less than 5 and is CFC/HCFC-free with an Ozone Depletion Potential (ODP) of zero.
The GL250-03 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.
