TREX FASCIA INSTALLATION RECOMMENDATIONS(DOES NOT INCLUDE TREX TRIM INSTALL RECOMMENDATIONS)Trex Fascia utilized around the perimeter of a deck mustbe gapped with the same requirements as Trex deckingto allow for air flow and expansion/contraction of thefascia.The gapping requirements are as follows:WIDTH-TO-WIDTH GAPBelow 40 F (4.5 C)3/8" (10 mm)Above 40 F (4.5 C)1/4" (6 mm)END-TO-END/END-TO-WIDTH & ABUTTING GAPEnd-to-End/End-to-WidthAbuttingAbove 40 F (4.5 C)1/8" (3 mm)1/4" (6 mm)Below 40 F (4.5 C)3/16" (5 mm)1/2" (13 mm)Trex recommends the use of Starborn DeckFast Fascia System, for all composite Trex fascia profiles.For near water applications, you can also use FasciaSystem HeadCote stainless steel screws.DECKINGIf using 2 x 8 framing, use two screws every 18"(457 mm). If using 2 x 10 or greater framing, use threescrews every 18" (457 mm). Follow manufacturer22instructions for further install instructions and ALWAYSremember to gap fascia properly. A secondary glue isnot required when using these fasteners.If using standard decking as fascia or stairrisers:This does not apply to standard decking boardswhen used in fascia applications as this productcan only be used with 1/2" (13 mm) to 3/4" (19 mm)standard composite fascia profiles. If you are using adecking board for fascia applications, use three Trexrecommended composite decking screws every 12"(305 mm). The top screw should be placed 1" (25 mm)from the top of the rim joist, the second screw in thecenter of the rim joist, and the third screw 1" (25 mm)from the bottom of the rim joist. In addition, also usea weather-resistant, construction-grade adhesive(adhesives that work with wood will work with Trexproducts) as a SECONDARY fastener when attachingfascia. Remember to wipe away any excess beforedrying or allowing to drip on other Trex surfaces.ADDITIONAL TIPS:» 10" (254 mm) rim joists allow for an easier and moreaesthetically pleasing installation.» Miter cuts at butt joints and corners allow for a moreaesthetically pleasing installation.
FRAMING AND FASTENING TIPSFASTENING TIPS FOR TREX ESCAPES*You can fasten Trex Escapes with therecommended fasteners at least 1/2" (13 mm)and not more than 4" (102 mm) from the boardedge without splitting. You do not have to predrill with Trex Escapes.*Use Trex Universal Hideaway Hidden Fastenersfor Escapes grooved product. This includesadditional screws for installation.FASTENING TIP FOR TREX ESCAPES,TREX TRANSCEND, TREX ENHANCE, ANDTREX SELECTNOTE: When using pneumatic or batteryoperated equipment, adjust the pressure sothat you only shoot the head of the screw to beflush with the board’s cap. DO NOT shoot thefastener head completely through the cap.TREX AND STATIC ELECTRICITYTREX PRODUCTS NEAR LOW-E WINDOWSLow-E glass reflects more sunlight, and ithas been observed that the extra reflectivitycombined with any concavity in the glass canact like that of a concave mirror, concentratingsunlight onto outdoor objects, including thatof decking and railing. This can result in anextreme amount of heat concentrated onareas of the decking surface, which in turn cansometimes char the decking surface or causethe decking to slightly bow.At board ends on thedeck's edge, you caninstall screws placedperpendicularly atthe recommendeddistance, atminimum of 1"(25 mm) from theboard end and edge,without splitting theboard.1" (25 mm)1" (25 mm)For butt joints, whereboards meet over asingle joist, add a2" x 4" (51 mm x102 mm) “nailer”board at the buttjoint. This allows youto install a screw at a90 angle.DECKINGThe buildup of static electricity on a flat surfacecan affect walking surfaces. This phenomenoncan occur in dry climates, where hot dry windsand dust-born particles can create staticelectricity on the surface of the decking. (Thisstatic electricity is the same as when peopledrag their feet on a dry day or rub a balloonon fur or wool.) In most cases, hosing downthe decking surface will dissipate the staticcharge, however if this continues the deck canbe grounded. Consult with an electrician todetermine the best methods for this.Composite decking is a great alternative totraditional wood decking. When building your deckand railing, it is recommended that code-approvedstructural material be used as the framing andjoists. One option is using Trex Elevations steeldeck framing. Refer to www.trex.com for moreinformation on Trex Elevations. Check your localbuilding codes for restrictions. Trex decking cannotbe used for structural applications.DO NOT attach Trex decking directly to any solidsurface or watertight system. See Sleeper Systemson page 24. In most cases, install fasteners at a 90 angle (perpendicular to the board).DOCK APPLICATIONSTrex decking contains no materials thatwill harm marine life and is safe forthe environment. As long as dock is inintermittent contact with water, i.e.,splashing and not in continuous directcontact with water, the durability of theTrex decking should not be affected.For docks, a 3/8" (10 mm) width-to-widthgap between boards is recommendedto allow for increased drainage due toincreased contact with water. In addition,stainless steel fasteners should be used.If there is sufficient contact with the dockand gasoline, grounding of the dock isalso recommended.NOTE: Construction methods are always improving. Please refer to www.trex.com for the most up-to-date installation requirements.23
ROOFTOP AND SLEEPER DECK SYSTEMSA sleeper system is a substructure between a solid surface and Trex decking. Drainage, access, and airflow arecritical. Water must be able to flow through and away from the deck. For repairs and removal of debris, joist systemaccess may be necessary.Gap decking from solid object (i.e. wall)1/4" - 1/2" (6 - 13 mm) dependingon temperature at installation(See note below for more information.)Trex DeckingWhere Trex decking is end-to-end and meets at a joist,add a “nailer or sister joist” at the butt joint of the decking.This will allow ends of each board to rest on a seperatejoist and be attached properly.Solid WallAttach sleeper/bearerjoists to stable substructure(i.e. wall and/or concreteGap decking width-to-width 1/4" (6 mm) - 3/8" (10 mm)depending on temperature at installation(See note below for more information.)Flat level surface (i.e. concrete)DO NOT ATTACH to unstablesubstructure such as concreteblocks or pavers setting in gravel,sand, dirt, etc.DECKINGCode-approved bearer substructureMinimum 1- 1/2" (38 mm) thick and1- 1/2" (38 mm) in height(See note below for more information.)» It is recommended that building code approvedstructural material be used as the supports.» Gapping rules are required when installing Trexdecking:TYPE OF GAP24Above 40 F(4.5 C)Below 40 F(4.5 C)Width-to-Width1/4" (6 mm)3/8" (10 mm)End-to-End1/8" (3 mm)3/16" (5 mm)End-to-Width1/8" (3 mm)3/16" (5 mm)Abutting Solid Objects1/4" (6 mm)1/2" (13 mm)» This system should not be allowed to float; it mustbe attached in a manner that secures the framing/system.» The sleeper system must be level and have no unevenundulations. Any uneven areas of the substructurewill transfer to the Trex decking, resulting in unevendecking.» Trex, when used with a sleeper system, must besupported below its entire length and if using ina roofing application, the supports must run thedirection of the pitch of the roof to facilitate properdrainage. Sleeper should be placed perpendicular tothe deck board orientation.Residential No greater than 16" (407 mm) on centerCommercial No greater than 12" (305 mm) on center(See note below for more information.)» For Commercial applications it is recommendedto consult local building code official for specificrequirements.» If installing decking at angle, decrease spans4" (100 mm) for each of the above. (12" (305 mm)for residential and 8" (204 mm) for commercial.)» For sleeper systems where little debris (pine needles,leaves, sand, dirt) can accumulate either between orunder deck boards, a minimum of 1-1/2" (38 mm)height is allowable and Trex Universal HiddenFasteners can be used. (NOTE: Trex recommendedcomposite decking screws are too long when using1-1/2" (38 mm) height as this will penetrate throughthe sleeper.) For areas with the potential for debrisbuildup, a minimum 3-1/2" (89 mm) or greater heightis recommended to allow the debris to be removedalong with the use of either Trex Universal HiddenFasteners or Trex-recommended screws.» ALWAYS consult your local building code authorityfor proper details on roof and railing installation to theroof structure if required.» Any deviation from these recommendations couldresult in the voiding of the Trex warranty.
CODE COMPLIANCEJoist Spanning for DeckingTrex decking meets all applicable national modelbuilding codes. The joists must be spaced on centeraccording to the chart below. Be sure that joists arelevel and plumb. Trex decking must span at least threejoists. For heavy items such as hot tubs, planters,etc., consult a local building engineer or inspectorfor span recommendations. If you want to minimizethe appearance of joists through the spaces betweenboards, paint the top of your joists black.ADJUST JOIST SPANNING TO ACCOMMODATEANGLED DECKING PATTERNS90 60 Code ListingsTrex complies with major model building codes andhas been evaluated by the International Code Councilevaluation service.Perpendicular to joists.See chart below.At a 60 angle, maximumjoist spanning is 2"(51 mm) less than listed inthe chart below.For a Safety Data Sheet (SDS), please visit www.trex.com30 45 Trex Transcend and Trex EscapesTrex Transcend and Trex Escapes are compliant with theWildland-Urban Interface, California State and San DiegoCounty fire codes.For more information, e-mail question@www.trex.com or call1-800-BUY-TREX (1-800-289-8739).At a 45 angle, maximumjoist spanning is 4"(102 mm) less than listedin the chart below.At a 30 angle, maximumjoist spanning is 1/2 ofthe distance listed in thechart below.Residential Decks, Light Duty Docks,Residential/Day Care PlaygroundDecking LoadingCommercial Decks,Boardwalks and Marinas100 psf 4.8 kN/m2100 psf 4.8 kN/m2200 psf 9.5 kN/m21" (25 mm) Boards (including Porch),and .875" (22 mm) Select Boards16" (406 mm)16" (406 mm)12" (305 mm)2" x 6" (51 mm x 152 mm) Boards24" (610 mm)24" (610 mm)16" (406 mm)DECKINGTREX DECKING SPAN CHART (On Center)TREX RAILING SPAN CHARTMaximum Railing Span for all ApplicationsTranscend, Select railing, andReveal railing96" on center (2438 mm) for Transcend, 72" on center (1829 mm) for Select,96" (2438 mm) clear span for RevealNOTE: Construction methods are always improving.

GAPPING and OVERHANGYou must gap Trex decking, both end-to-end andwidth-to-width. Gapping is necessary for drainage andthe slight thermal expansion and contraction of Trexdecking boards. Gapping also allows for the shrinkageof the wood joist system.» ALWAYS follow Trex-recommended gappingguidelines.» Maximum allowable perpendicular overhang for allTrex decking is 1/2" (13 mm).» All decks require air circulation to keep them dry andlooking good. To improve air flow, leave openingsunder the decking or increase gapping to 3/8"(10 mm).WIDTH-TO-WIDTH GAPAbove 40 F* (4.5 C)*1/4" (6 mm)Below 40 F* (4.5 C)*1/4" (6 mm)1/4"(6 mm)Width-to-WidthThe minimum required width-to-width gapping is1/4" (6 mm).
