Product details
The "SD" hinge down steel 60-minute fire rated loft access hatch has a simple design for the contemporary modern house.
Can be operated from floor level with a pole - found in the loft hatch accessory section
With its powder coated zintec steel smooth white maintenance free finish. The loft hatch requires no painting and projects into the ceiling space a mere 8mm.
Once the drop down loft door is opened, the 536x736 and 600x600mm options have a minimum clear opening to satisfy building regulations, and is therefore compliant to NHBC regulations as Chapter 7.2 Section D14 "to a minimum clear opening of 520mm in any direction". This will assist if you have catered for storing sizeable items in the attic.
The loft access hatch is insulated with an exposed fire resistant mineral slab insulation to comply with the building regulations 0.35 "U" value.
The SD loft hatch is compatible with our entire range of loft ladders.
The loft door has a 25mm flange that projects beyond the fitting size. The SD loft hatch has concealed hinges and fixings contributing towards its unobtrusive look.
The loft access door has a neat tri-drive budget lock with an integral chamfer for a smooth closing action. A secure radial pin tumbler lockable version is available (SDL).
The loft panel is fully draught sealed between the door and frame, virtually eliminating warm air leakage and vapour ingress. It also assists with ease of decoration of the ceiling up to the edge of the loft access trap frame.
