Aluminium or wooden ladders
can be combined with either an MDF door fitted to the exiting
opening or with a High Impact Polystyrene hatch unit (Visually
indistinguishable from uPVC)
The MDF door will be fitted to the existing hatch opening
and a twist catch fitted to secure it in the closed position.
All the ladders include a stow pole which is used to operate
the twist catch.
In place of the MDF door we can re-size the hatch aperture
and fit the HIP hatch unit. This usually means increasing
the existing opening. The dimensions of the HIP hatch opening
are 726mm x 562mm. The unit has a 45mm pencil rounded architrave
and is draft proofed where it meets the ceiling. The hatch
door is draft proofed where it meets the frame and it has
a 50mm layer of polystyrene insulation. The door is also
removable which gives a little more room if an object is
a tight squeeze. The hatch door is secured by a flush fitting
twist catch that operates a lever style lock in the centre
of the door and two bolts out to the sides. The stowing pole
that’s used for the ladders will open & close the
hatch door. |
