General Requirements
5.1
Seams
Keep seams to a minimum. When possible, position seams so that:
· Seams should run the length of the area.
· Main traffic should run parallel to, rather than across, the seam.
· Natural light does not strike across the seam.
· Seams are away from areas subjected to pivoting traffic.
· Seams are not perpendicular to doorway openings.
5.2
Pile Direction
Where two or more pieces of the same broadloom carpet are adjacent, the pile direction is
required to be the same unless otherwise specified. Uniform pile direction is not required
with dissimilar carpet.
NOTE: Ideally, install carpet with the pile lay toward the entrance; but other factors, such as
pattern, aesthetics and economic use of material may be considered.
5.3
Layout and Trimming
Carpet shall be cut in accordance with the seaming diagram, allowing at least 3 inches
along each wall for trimming and sufficient material to match patterns when applicable.
5.4
Transitions to Other Surfaces
Where carpet transitions to other floor coverings, the carpet edges are required to be
protected or covered with appropriate transition moldings. The edge of the hard surface
flooring should not exceed a maximum of 1/16” higher than the total carpet thickness
where no transition molding exists. For broadloom where no transition molding is used,
apply a minimum of 1/8” bead of seam sealer to the edge of the carpet along the entire
transition.
Wall base - when vinyl or rubber wall base is used in a direct glue or double glue carpet
installation, cove base or base-with-toe is highly recommended.
5.5
Carpet over Carpet
In the absence of manufacturer’s specific recommendations to the contrary, carpet should
not be installed over existing carpet.
