Timbertech Composite™ Decking, Terrain+ Collection™

Tools Required: Cordless driver, chalk line, tape measure, jig saw, carpenter square, spacing tools, circular saw, safety glasses, drill bits

Walking Surface: TimberTech® boards are intended to be installed embossed side up only. The unembossed surface is not to be used as a walking surface.

Static Electricity: The buildup or generation of static electricity is a naturally occurring phenomenon in many plastic based products such as carpeting, upholstery, and clothing, and can occur on alternative decking under certain environmental conditions.

Safety: Unlike traditional wood, TimberTech® product is splinter-free. Color and Grain Patterns: TimberTech® Decking is designed to mimic the look of real wood, and like real wood, there will be a slight difference in color and grain pattern from board to board. This is intentional and part of the manufacturing process, giving TimberTech® decking the most realistic and wood-like appearance possible. This variation is purely aesthetic and does not or will not affect the performance of the product. When working with multiple units of decking, consider pulling boards randomly to mix rather than completing one unit at a time. It is always a good practice to layout deck boards in different lighting conditions/ angles before final fastening.

Note: TimberTech® is NOT intended for use as columns, support posts, beams, joist stringers or other primary load-bearing members. TimberTech® must be supported by a code compliant substructure. While TimberTech® products are great for deck re-boarding (removing old deck surface boards and installing TimberTech® on code-compliant substructure), TimberTech® boards CANNOT be installed on top of existing deck boards. Routing: TimberTech® Decking should not be routed on the edges, ends, or sides with the exception of the start/stop boards as shown in this guide (under CONCEALoc section).

Notching: Whenever notching a board for a post or any obstruction, the deck board must be handled carefully and be fully supported under the notched area when installed.

Calculating Material Requirements: To determine how much TimberTech® decking material you will need, start by calculating the square footage of your. deck surface by multiplying length by width. Once you know this number, divide it by the numbers provided below for 12 ft. boards, 16 ft. boards and 20’ boards. Once you know the square footage number, divide it by 5.5 for 12 ft. boards, 7.3 for 16 ft. boards and 9.1 for 20 ft. boards. When calculating the amount of decking you will need, it is recommended that you add roughly 10% to the total for a scrap factor.

     Example: Length x Width = Total Square Footage Square Footage ÷ by 5.5 (12 ft.), 7.3 (16 ft.) or 9.1 (20 ft.) = Boards Needed (Round the number up) Boards Needed + 10% (Scrap Factor) = Final Number of Boards Needed (Round the number up) Gapping Requirements: • Side-to-side board gapping must be minimum 1/8 in. to maximum 3/16 in. • Allow 3/16 in. minimum gap where the boarding meets any adjoining structure or post. Butt Joint Gapping Requirements: 32° F and below: 3/16 in. gap 33° F to 74° F: 1/8 in. gap 75° F and above: 1/32 in. gap
