3. FASTENERS

Composite Screws:To fasten decking, use 2 ½ #8 composite screws. Color matching fasteners are available in the market.It is very important to not use lower quality nails or screws as they can rust or corrode, which willpotentially leave marks or stains on the decking materials. Pre drilling fastener holes prior to installingcomposite fasteners is a standard practice within the composite decking industry and should beconsidered with TerraDeck™ depending upon the final installation requirements of the customer.

Hidden FastenersNatures Composites decking profiles accept most hidden fastener clips available on the market,including but not limited to:

1. Tigar Claw TC-G2. Invisi Fast (TD) or (TXB)3. Simpson Strong Tie 316-TS or 316-TT4. Deck Clip™5. Others – closely reference specifications before using hidden fasteners with TerraDeck™

profiles

Note: reference hidden fastener specifications and guidelines prior to making your selection. Warrantyand gapping will vary depending upon the hidden fastener technology you select.

5. DECK INSTALLATION

5.1. LOCAL AND REGIONAL CODES

Always reference and follow local building codes.

5.2. VENTILATION

5.2.1. Proper ventilation must be allowed for beneath the joist structure of your deck to reducethe potential of moisture build up. It is recommended that at least 10 vertical inches offree air space be left open between the ground and the bottom of the joist substructure ofthe deck.

5.3. JOIST STRUCTURE

5.3.1. When constructing a traditional deck with deck board laying perpendicular with thejoists, joists shall be positioned 16 inches on center maximum from one joist to another.All joists should be flush with each other and as flat as possible to provide the optimumdeck surface. When installing at an angle, span joists 12” on-center to maintain theproper strength and support necessary.

16”MAX

NOTE: To avoid water run-off damage to house, deck structure should have a minor slope downtraveling away from the house.


5.4. TERRAPOST INSTALLATION

5.4.1. Position TerraPosts along the interior of the rim joists of the deck frame. Post lengthshould be cut to allow for the proper deck rail height in compliance with applicablebuilding codes in your area in addition to enough post material to securely attach to the joiststructure. The maximum distance between posts shall not exceed 72 inches. DO NOTNOTCH THE POSTS.

72”MAX

CODES

5.4.2. Secure posts to rim joist by first adding blocking around the posts. Then drill holes andinstall two Ø1/2” X 8” long carriage bolts, washers and nuts per post. Holes should belocated 1” from the top and bottom of the joist and centered across the post.

1”1”


5.5. TERRADECK SOLID INSTALLATION

Begin installation of Terra Deck board on the outside edge of deck and proceed to laynext boards towards the house. Attach deck board to joists using screws. Two (2) screwsshould be installed at each joist in each deck board. Screws should be positioned ¾ inchin from sides of deck board and no closer than ¾ inch from the end of the deck board.Install deck screws flush with deck board. When installing screws less than 2 inchesfrom the end of deck board, holes should be pre-drilled in the deck board beforeinstallation of the screws. Pre-drilling holes at the end of deck board will reduce the riskof splitting the TerraDeck™ product.

INSTALLINGSCREWS

Continue installation of deck boards by positioning another deck board next the prior,while maintaining a consistent 1/4” to 3/8” gap between deck boards. When installingTerraDeck™ boards end-to-end an 1/8” gap needs to be left between boards to allow forexpansion. When abutting ends of deck board to a solid structure, such as a house, a 1/4”minimum gap should be left between the structure and the end of the board.

into the slot on the deck board.5.6.3. Install hidden fasteners by first making sure deck board is pressed securely against the

Start/Stop clip. Then insert the hidden fastener into the slot in the deck board and secureby screwing into joist. Do not fully tighten hidden fastener has this will allow the nextboard to be installed into these fasteners. Repeat this step with remaining deck boards.

6. RAILING

6.1. Railing (TerraPost™ mounted inside joists) System using “L” Handrail6.1.1. Measure the distance between two posts and cut a top rail and a bottom rail. See Figure 1.

Figure 1


6.1.2. Position the bottom handrail between the two posts. Cut a couple of blocks of wood tothe desired height of the bottom handrail. Note that the maximum open gap between thedeck surface and the bottom rail is 4 inches. Place these blocks under the bottom handrailto hold it in place. Reference Figure 2.

4”MAX.

6.1.2.1. Now place a cut to desired length baluster against the post and resting on the bottomrail. Center the baluster along the post and attach to post with screw spaced no morethen 6 inch apart as shown in Figure 3. Repeat on the other post.

7. RAILING

7.1. Traditional Style Railing

7.1.1. TerraPost™ (mounted outside of floor joists)7.1.1.1.Cut post to length. The height of the railing system should be 36 inches minimum to

42 inches maximum from the top of the deck to the top of the railing as shown inFigure 10. Posts should be cut to length to provide the railing height requirement aswell as long enough to provide substantial attachment to the deck structure.

36” - 42”

Figure 10


7.1.1.2.When installing posts a filler block must be placed to provide additional support ofthe hollow post to the deck structure. Filler block can be fabricated from a TerraRailboard cut to fit within the TerraPost approximately 12 inches long. Filler blockshould fit tight against the inside of the post in the direction that the bolts will be intothe post to attach to the deck structure. Inside dimensions of the hollow post are 2.5”x 2.5”.

12”

Filler block

7.1.1.3. With filler block centered with the hollow TerraPost and flush with the bottom ofthe post attach the post to the deck structure with 1/2 inch diameter carriage bolts (seeFigure 12). Allow 1 extra inch length of TerraPost if customer wants to install postcap on bottom of post. With the post positioned and plumed drill holes through thepost, filler block and deck structure. Install carriage bolts through all and secure inplace with washers and nuts on the backside of the deck structure as shown in Figure12.

Figure 12

Repeat process for additional posts. Recommend maximum post spacing is 48inches.


7.1.2. Vertical Railing

7.1.2.1.To install top vertical railing, attach a standard lumber 2x4 hanging bracket to post sothat when rail is installed it is flush with the top of the post as shown in Figure 13.Install bracket on opposing post in similar manner. Cut rail to length. Rail lengthshould be cut 1/8 to 1/4 inch shorter than the measured distance between brackets toallow for thermal expansion. Secure rail in bracket with 1 inch screw, or per bracketmanufacturer’s recommendations.

Figure 13

7.1.2.2.The bottom vertical rail is attached using the same hardware as the top; however it ispositioned so that the distance between the deck and the bottom of the vertical rail is3 inches maximum. Reference Figure 14 below.

7.1.3. Top Hand Rail7.1.3.1. For top rail, cut TerraDeck solid board to desired length. Attach top rail to top

vertical rail by first centering the board on the posts and vertical rails as shown inFigure 15. Then using 2 ½ inch long screws attach top rail to top vertical rail onescrew every 12 inches.

TOP RAIL

Figure 15

7.1.3.2.If multiple top rail boards are required on a linear section of rail, it is recommendedthat a “scarf” joint be used similar to one shown in the Figure 16 below. The joiningends of boards should be cut at 45° angles. Position the joint centered on a post.

SCARF JOINT

7.1.4. Balusters7.1.4.1.Cut balusters to length. Length of balusters should be from the bottom of the top rail

to the bottom of the bottom vertical rail as shown in Figure 17 below. A mitered cut,such as 45° may be cut on the bottom end of the baluster to add additional visualappeal.

7.1.4.2.Attach balusters to the vertical rail using 2 ½” long composite screws. Two screwsshould be used on the top and two on the bottom of each baluster. Spacing forbalusters is 5” with the maximum free space gap between the balusters not to exceed3 ½”. Reference Figure 17 below.
