Installation Instructions

The ceiling system is made up of Armstrong
panels (either 2′ x 4′ or 2′ x 2′) which are
supported by a suspension system (main
beams, cross tees
and hangers), and
perimeter molding.
The integrity of the
entire suspended
ceiling depends on
the hangers –
commonly wires –
which are used
to support the
suspension system main beams. Sections of
main beams are spliced together and are
connected by cross tees. The ends of the main
beams and cross tees rest on the wall molding
which runs around the perimeter of the space.
Before You Start
Although temperature and humidity
recommendations vary by product, the space
must be cleared of debris and, in general,
should be enclosed.
• The ceiling panels should be kept clean, dry,
and protected from the elements. Panels
should be removed from cartons 24 hours
before installation to allow them to adjust to
interior conditions.
• The tools you will need will vary depending
on the type of hangers used, but generally,
you will need: ladders or scaffolding; a tape
measure; pencil; chalk line; hammer; powder-
actuated fastener; awl; pop-rivet gun; screw
driver or drill; sheet metal punch; aviation
snips; wire cutting pliers; utility knife; level
(water level or laser); string; key hole saw;
and compass or dividers. Most jobsites also
require some safety equipment like a hard hat
or safety glasses.
