Installing TimberTech® Decking TimberTech Decking should be installed using the same good building principals used to install wood or composite decking and in accordance with the local building codes and the installation guidelines included below. AZEK® Building Products Inc. accepts no liability or responsibility for the improper installation of this product.
Installing TimberTech® Decking Extreme Heat Warning Be aware of excessive heat on the surface of TimberTech products from external sources, such as but not limited to, fire,hot ashes/embers, fire pits, grills, or reflection of sunlight from Low-emmissivity energy-efficient window products. Low-emissivity (Low-E) glass can potentially harm TimberTech products. Low-E glass is designed to preventpassive heat gain within a structure and can cause unusual heat build-up on exterior surfaces.
Installing TimberTech® Decking Substructure/Preparation Follow these guidelines for best deck installation: • Prior to installation, check to make sure all joists are level structurally sound, and there are no nails or screws protruding • As joists are installed, run string line frequently to en sure that the tops of the joists are in plane, as Timbertech Decking will conform to the contour of the joists to which it is attached.
Fastening Methods TimberTech® Square Shouldered Boards TimberTech recommends the use of TimberTech Cortex or TOPLoc for PRO and EDGE for square shouldered deck board installations. Pre-drilling is required when within 1-1/2”of the ends of the board and for temperatures below 45 degrees Fahrenheit to avoid splitting and screw shear. Alternate fasteners are stainless steel or high-quality coated composite deck screws.* TimberTech EDGE Collection (4- Sided Cap) 5.360” .
TimberTech® Square Shouldered Boards TimberTech PRO™, TimberTech EDGE™, ReliaBoard® • On-grade decks must have additional provisions for drainage beneath the deck structure. • For best practices, decking should not be installed in applications where ventilation and airflow cannot be achieved. Important Information To get information on other TimberTech products, visit timbertech.com or ask your dealer for these installation guides: • TimberTech boards are intended to be installed em bossed side up.
Square Shouldered Boards/Trimming a TimberTech Deck TimberTech PRO™, TimberTech EDGE™, ReliaBoard® Stair Installation TimberTech does not recommend installing boards on steps without a riser board. • Stairs should be constructed per local code requirements. • Ensure the stringer step is at least the depth of two full boards plus a 1/8” to 3/16” gap between boards. • For gapping requirements, see page 3 • Ensure there is at least one stringer for support in the middle of the stair span.
CONCEALoc® Hidden Fastener Important Information CONCEALoc Accessories CONCEALoc Hidden Fasteners were designed exclusively to install TimberTech grooved boards. Always be sure to check and cut the factory cut ends of all boards to ensure they are square. • In areas with obstructed airflow such as roofs and on-grade applications, a minimum of 1-1/2”, sleeper system,is required. • Sleeper system must be supported by and connected to the substructure over which the deck is built.
CONCEALoc® Hidden Fastener 3 INSTALL CONCEALoc® FASTENERS • Install provided CONCEALoc® screw at 45° angle through the fastener and into the joist while applying pressure on the fastener. • Install one fastener and screw at each joist location. See specific and additional require ments for butt joints. • Make sure fastener is in full contact with edge of baord and the screw is holding the fastener down tight to the deck board.
CONCEALoc® Hidden Fastener 6 HOW TO: INSTALL ON DIAGONAL • When the deck is located in a corner of the house, start with small triangular piece of decking in the corner and work your way out. • Offset the center 1/2” towards the long point of the joist, so screw will not exit the side of the joist when driven. Incorrect 7 Correct: Shift over 1/2” COMPLETE INSTALLATION • Make two parallel cuts down the center of the board to be replaced, then remove the. center piece.
Cortex® Hidden Fastening System Cortex® Hidden Fastening System Installation Instructions Suggested Drills Impact Drivers are not recommended when using TimberTech Cortex. Corded or cordless drill Restricted Cortex Uses Important Information • Pre-drilling with a 7/32” drill bit is always required when installing Cortex in TimberTech decking. • The Cortex Setting Tool must be used to set the Cortex screw to the proper depth.
Cortex® Hidden Fastening System 1 PRE-DRILL • Pre-drill deck board with a 7/32” drill bit 2 DRIVE SCREWS INTO JOISTS • Using Setting Tool provided, drive screw at medium or high speed until it disengages at the proper level below the deck surface. • Drive at one continuous speed, do not slow down. • Install two screws into decking at each joist • Maximum spacing between each row of screws should be 16” on center.
FUSIONLoc® Hidden Fasteners Installation FUSIONLoc® Hidden Fasteners for use with TimberTech Deck Boards IMPORTANT: Deck Board must be secured tightly and in full contact with the joist after each clip is installed. Not doing so could result in issues such as an uneven deck surface, noise, and board movement caused by an improper loose attachment. FUSIONLoc & Accessory Installation Instructions • FUSIONLoc Hidden Fasteners – packaged for 225-square-foot and 450-square-foot, at 16” O.C..
FUSIONLoc® Hidden Fasteners Installation 2 INSTALL THE FIRST PLANK • Fasten outer edge of the first plank at each framing support 1” from the edge using recommended fasteners. For a complete fastener-free surface, Cortex can be used on first and last boards. Note: Cortex and the L-Brackets should not be used with TimberTech Terrain or ReliaBoard. 3 PLACE THE FUSIONLOC GUN INTO POSITION • Fully insert the FUSIONLoc fastener into grooved edge of plank.
