PLANNING AHEAD
Installing Hot Tubs, Planters, and Seating:
» Plan ahead proper joist spanning if required (this is
especially important if installing a hot tub).
» Refer to page 16 for Trex Decking Span Chart for
specific loads.
Call 1-800-BUY-TREX for detailed questions.
Installing Fireplaces and/or Fire Pits With
Trex Decking:
» Determine if fire will be gas or wood burning.
(NOTE: Most fire pits shown in Trex images are
gas burning.)
» For gas, the fire pit is installed by cutting around the
Trex decking. It is not to be installed on top of Trex
decking. A fire-resistant material is installed under the
fire pit and a protective wall made from stone or other
fire-resistant material is installed to hold fire pit in place
and also protect the decking from heat.
» For wood, fire pits are not recommended on top of Trex
decking unless using a product called DeckProtect
®*
.
Wood-burning fire pits can damage the decking
due to extreme heat from the bottom of the fire pit
and/or burning embers shooting onto the decking.
DeckProtect
®
was tested on all Trex decking and there
were no issues with burning of the decking surface
when placed directly under a standard size portable fire
pit along with the accompanying rack (NOTE: Rack is
not available for all sizes, so check with manufacturer
first for verification).
Trex does recommend that the DeckProtect
®
padding/
rack be moved from time to time for general cleaning
underneath. It should be noted that even when using
DeckProtect
®
, burning embers could shoot beyond the
protective mat and burn the deck.

Installing a Pergola on Trex Decking:
» Keep in mind that if you are planning to install a Trex
®
Pergola™ on your deck, you will need access to the
underside of the deck. Trex Pergola mounts with a
10" x 10" (254 mm x 254 mm) aluminum plate on the
underside of the deck, creating a clamping eect on
both the top and bottom of the deck for maximum
strength. If installed, water barriers and any under deck
coverings will have to be removed to properly install the
pergola posts.
» You need to consider the location of your pergola
posts with respect to joists. However, you do not have
to mount your plates between joists. It is possible to
place blocks on the bottom of the joists and mount the
Trex Pergola brackets through the blocks.
