Hidden fastener instructions - grooved edge fastening systems
Installing PE capped
composite decking
Installing Paramount PVC decking
All approved face fasteners and hidden
fastener systems are listed on the
berondecking.com website, including
specic instructions for Paramount PVC
grooved deck boards. These fasteners
are designed to accommodate normal
dimensional changes without material
fracture or change in holding capability.
The use of hidden fasteners is not
recommended for installations above
elevations of 6,500 feet.
Fiberon recommends the Tiger Claw TC-
G
®
hidden fastener, used in combination
with Fiberon Cortex
®
fasteners as the only
approved system for installing hidden
fasteners in grooved Fiberon Paramount
deck boards. The combination of fasteners
will ensure equal expansion and contraction
in both directions.
Secure boards using two Tiger Claw TC-G
hidden fasteners at each joist. Center-pin
the board at the centermost joist with two
Cortex fasteners.
Note: Fastener parts have sharp edges. Use
proper care when handling.
Fiberon recommends the use of a quality
joist ashing to ensure optimal installation
and reduce potential noise caused by the
boards moving against the joist. Products
such as Grace Vycor Deck Protector, Tite
Seal, or other comparable self-adhesive
ashing products enable for a smooth and
consistent contact surface between joists
and Fiberon Paramount decking. Paramount
deck boards have a lifetime limited warranty,
and joist tape will extend the life of the joists
upon which the deck boards are fastened.
Paramount is approved for use over joists
spaced 16 in. on center. However, Fiberon
recommends spacing the joists at 12 in. on
center to increase stability and reduce the
exing of the deck boards.
Any use of unapproved fasteners, including
biscuits or nails, may lead to product failure,
and will void the product warranty.
Tiger Claw TC-G fasteners should be
secured to each joist with an impact driver.
Fiberon Phantom 20EC End Clip Fasteners
may be used for hidden fastening on
perimeter boards and fascia boards.
Use two Cortex screw per deck board
to limit the movement of the deck board
against the joist. The Cortex screws should
be placed into the joist closest to the mid-
point of each deck board. This helps to
ensure the deck board stays positioned
as the board expands and contracts with
temperature changes.
The PhantomEC and PhantomGT hidden
fasteners are part of a deck fastening
system designed specically for grooved
(GV) deck boards. These fasteners provide
a fast and simple way to create a smooth
deck surface, uninterrupted by visible
screws or nails. All are sold separately.
Note: Fastener parts have sharp edges. Use
proper care when handling.
Secure Fiberon PhantomEC end clips a
minimum of 1/4 in. from the wall with a
single screw into the joist. Space clips no
greater than 12 in. apart. Position the deck
board into the end clip fasteners. It may be
helpful to angle the board slightly to fully
seat it into the clips. Check to ensure that
the board is fully inserted into the clips.
Insert a Fiberon PhantomGT fastener into
the groove of the board, centering on joists.
