Safety & Installation
through plaster/other ceiling material (see table 1). This allows
space for spacer blocks and ensures that the loft ladder is fitted
perpendicularly. If the loft ladder cannot be fitted in the normal way,
i.e. parallel with the ceiling joists, contact a qualified craftsman for
advice. Figures 2, 3 and 4 show how to frame the ceiling opening.
If you fit the loft ladder parallel to the
existing ceiling joints, only single ceiling
joists and single transverse joists are
required. If you fit the loft ladder at right
angles to the joists, you will need to
make double transverse joists of the
same size as the existing ceiling joists.
WARNING
: If the ceiling joists are made
in a material other than timber, e.g. steel,
contact a qualified craftsman. Never
saw through a load-bearing joist without
advice from a qualified craftsman. Take
great care when sawing ceiling joists. For safety's sake, if there is no loft flooring, lay planks across the
ceiling joists to allow safe passage in the loft during installation.
04
Fitting temporary supports:
To keep the loft ladder in place in the ceiling opening during installation, you are advised to fit temporary
supports. If the trapdoor will be clad, the
loft ladder must be fitted as many mm
higher in the opening as the thickness of
the cladding. Cladding material must not
weigh more than 6kg per m
2
. Cladding
material must not be more than 12mm
thick. We recommend that the cladding is
affixed using construction adhesive.
WARNING
: It is important that cladding is fitted firmly and correctly. When affixing cladding, the ladder must
NOT be loaded.
05
Attaching the loft ladder:
One fitter goes up into the loft room, taking all the tools he needs. The other fitter remains below.
Lift the ladder up into the loft. Before lowering the loft ladder into the opening from above, attach 2
supporting planks under the ceiling opening. The loft ladder rests on these supports (see figure 5). Fold the
ladder so that the frame can be attached to the ceiling opening. Make sure that the loft ladder is level and
perpendicular. Attach loft ladder with adequate screws, allow at least half the total screw length to penetrate
the support joists, specified within Assembly Step ‘05’ on page 5 (3 on long side and 2 at each end). Don’t
forget to attach blocks on the back of the fixing points (see figure 6). When the loft ladder is firmly attached,
remove supports.
WARNING
: DO NOT use the loft ladder
before it is firmly attached to the opening
and adjusted to the correct ceiling height.
Vapour barrier
: When the loft ladder is
firmly attached to the deck, the vapour
barrier must be attached in the correct
way. The space between the loft ladder
and the joist construction must be well-
insulated to avoid thermal bridges.
