Folding Attic Stairs
Staircases that fold up to fit into the ceiling
are a great way to gain access to the attic
in your home or garage without having conventional
stairs take up valuable space. Folding stairs
are basically ladders that are pulled down
from a unit installed in an opening in the
ceiling that is typically 221/2 to 25 inches
by 54 inches. When not in use, their bottom
panels need to fit flat against the ceiling
to prevent heat loss. Look for models that
have insulation and weather stripping. The
stairs should be easy to operate by pulling
an attached cord or using a long pole with
a hook on its end that slides into a ring
attached to the flat bottom panel. Some models
have springs and gas pistons that help lower
and lift the stairs. Better stairs units
will hold at least 300 pounds and have sturdy
treads, stringers and hinges. These stairs
can be easily installed by a handy homeowner.
Consider the following choices
when buying
folding attic stairs:
- The most common type of folding stair is
made from wood and has two hinged ladder
sections that unfold when the stair is opened
so that it reaches the floor at a comfortable
climbing angle. These usually have stair
treads from 3/4 to 1 1/2 inches thick. Thicker
treads are better for those who will be moving
things in and out of the attic.
- Metal folding stairs can be made from steel
or lighter weight aluminum.
They cost more
than wood units, but often
last longer because
they have riveted construction.
Look for
slip resistant treads when
buying this type.
- Aluminum telescoping stairs are the most
compact. They can fit into
tight spaces such
as closets because they extend
straight down.
- The strongest type of attic stair is a one
piece wood ladder that is counterbalanced
by spring loaded drums so that
it glides
gently to the floor when the
bottom panel
is pulled down. These are sturdy
rigid models
that can reach up to 12 feet
and hold up
to 800 pounds. They are more
expensive than
other types, and there must
be enough clearance
under the roof for the ladder
to slide all
the way up.
Installing attic stairs requires three important
measurements: the width and length of the
rough opening in the ceiling and the ceiling’s
height. Most units can be trimmed to fit
a range of measurements. You also need to
know how much swing clearance and landing
length the stair will need when it is lowered,
especially if your space is tight. You should
have at least 24 inches in front of the stairs
for easy access. |
