Description

SD Hinge Down Steel 60-Minute Fire Rated Loft Access Hatch is manufactured from white powder-coated Zintec steel with a smooth finish. It requires no painting and protrudes a mere 8 mm into the ceiling space.


The loft access hatch is insulated with an exposed fire-resistant mineral slab insulation, complying with building regulations and guaranteeing efficient thermal performance.


The loft access door has a tri-drive budget lock with an integral chamfer, ensuring a smooth closing action. For enhanced security, a lockable version with a secure radial pin tumbler (SDL) is also available.


To maintain an airtight seal and prevent warm air leakage and vapour ingress, the loft panel is fully draught sealed between the door and frame. Additionally, this feature facilitates easy decoration of the ceiling up to the edge of the loft access trap frame.


Features and benefits:

  • Maintenance free finish.
  • Requires no painting.
  • 1 Hour fire rated (UKAS accredited).
  • Complies with Part L.
  • 555 x 755 mm and 600 x 600mm options comply with NHBC guidelines for minimum clear opening.
  • Airtight tri-drive lock (and key); key lockable option available
  • UKAS accredited air infiltration test compliant for loft access hatches without using sealant to the external frame.
  • Can be operated from floor level with a pole.
