What is a photoluminescent carpet stair nosing?
A photoluminescent carpet stair nosing is a rigid stair-edge
profile designed specifically for carpeted stairs. Ecoglo® C4-E20
combines protected luminous step-edge strips with a durable
silicon-carbide non-slip insert in an aluminum profile that covers
and defines the leading edge of the carpeted step.
Is the Ecoglo® C4-E20 designed specifically for carpeted stairs?
Yes. Unlike a flat stair-nosing profile, C4-E20 has a
carpet-specific right-angled aluminum shape that covers and
protects the front edge of the stair while providing a durable
transition at the carpeted step.
How wide is the Ecoglo® C4-E20 carpet stair nosing?
The C4-E20 profile is approximately 2.7 inches wide and
1.3 inches high. The current product page lists a non-slip insert
approximately 1.5 inches wide and product weight of approximately
0.57 lb per linear foot.
What colors are available for the C4-E20 carpet stair nosing?
The current ComposiGrip C4-E20 listing includes black, gray and
yellow non-slip insert options with clear-anodized or black-anodized
aluminum profiles. Models include C4171, C4161, C4151, C4271,
C4261 and C4251.
Does the black, gray or yellow non-slip insert glow?
No. The colored silicon-carbide insert provides traction and
daytime step-edge contrast. The adjacent protected
photoluminescent strips are the components that absorb ambient
light and glow when the surrounding lighting level falls.
Is a photoluminescent carpet stair nosing slip-resistant?
Yes. The C4-E20 uses an integrally bonded silicon-carbide
non-slip insert, while the protected ridges around the luminous
components also contribute to the stair-edge texture. The
product is designed to combine egress visibility with durable
anti-slip performance.
Does a luminous carpet stair nosing require electricity or batteries?
No. Ecoglo® photoluminescent material charges from suitable
natural or artificial ambient light. The passive system does not
require electrical wiring, batteries or ongoing electrical energy
at the stair nosing.
What lengths are available for the C4-E20?
The current ComposiGrip C4-E20 listing offers 2 ft, 4 ft, 6 ft,
8 ft and 10 ft lengths. Custom-cut lengths are also available
with the product page indicating an approximate ±1/8-inch
custom-cut tolerance.
How is Ecoglo® C4-E20 installed?
Manufacturer and current product information specify
polyurethane adhesive with mechanical fasteners, or adhesive
only where appropriate. The current C4-E20 product is supplied
with pre-drilled countersunk holes, stainless-steel fasteners
and concrete nylon anchors.
Can Ecoglo® photoluminescent carpet stair nosings be used outdoors?
The current C4-E20 information describes the product for indoor
and outdoor applications and references UV stability, salt-spray
resistance, freeze-thaw resistance and washability. Outdoor
installation details should still be confirmed for the exact
substrate, exposure and project.
Is C4-E20 suitable for luminous egress path marking projects?
Ecoglo® positions C4-E20 as a photoluminescent carpet stair
nosing for luminous egress and step-edge marking applications.
The current product information identifies the series as
UL 1994 and ULC 572 Listed. Final applicability should be
confirmed against the project's adopted code, specifications
and Authority Having Jurisdiction.
Why use a rigid carpet stair nosing instead of glow-in-the-dark tape?
C4-E20 is a purpose-built rigid aluminum stair-edge profile with
protected photoluminescent components and a bonded non-slip
insert. It also covers and defines the carpet transition at the
leading edge. This construction is different from applying a
flexible adhesive glow tape to the carpet or stair surface.
