how wide is trex decking with hidden fasteners

Trex decking is a high-quality composite decking material that offers a natural wood-like appearance with several advantages, such as durability, low maintenance, and resistance to insects, rotting, and splinters, among others. However, one of the most significant benefits of Trex decking is the availability of hidden fasteners that provide a seamless look and enhanced safety.

But, how wide is Trex decking with hidden fasteners? In this article, we will explore the answer to this question and provide essential information about Trex hidden fasteners and decking width.

1. What are Trex hidden fasteners?

Trex hidden fasteners are a concealed fastening system designed to attach Trex decking boards to the deck's substructure without visible screws or nails on the decking surface. The result is a sleek and uniform look without the danger of raised or exposed fasteners that can cause tripping or injury. Moreover, Trex hidden fasteners provide a secure and robust hold that reduces deck movement and eliminates deck board cupping, warping, or splitting over time.

There are two types of Trex hidden fasteners: the Trex Hideaway® Universal Hidden Fasteners and the Trex Hideaway® Start Clips. The Universal Hidden Fasteners are compatible with all Trex decking lines and securely attach the boards through the grooves along the sides of each board. On the other hand, the Start Clips are only used for the first and last boards of the deck, as they connect the boards from the sides.

2. What is the maximum joist spacing for Trex decking with hidden fasteners?

When installing Trex decking with hidden fasteners, it is crucial to follow the manufacturer's specifications for joist spacing to ensure optimal performance and safety. The recommended maximum joist spacing for Trex decking boards varies depending on the board's orientation and the decking line, but it ranges from 12 inches on center to 16 inches on center.

For instance, the Trex Transcend® and Enhance® decking lines can be installed with a maximum joist spacing of 16 inches on center for perpendicular installations, and 12 inches on center for diagonal installations. However, the Trex Select® line requires a maximum spacing of 16 inches on center for both orientations.

3. Can Trex decking width vary with hidden fasteners?

The width of Trex decking boards can vary depending on the decking line and the installation method. Typically, Trex decking boards are available in two widths: 5.5 inches and 7.25 inches, but some lines offer additional widths or custom options.

When using hidden fasteners, the width of Trex decking boards may appear slightly narrower than the actual width due to the gap between boards. Moreover, the gap size can vary depending on the fastener, the joist spacing, and the installation conditions, among other factors.

Therefore, it is essential to consider the gap size when calculating the required number of decking boards for your project and to follow the manufacturer's guidelines for gap size and board orientation to ensure adequate ventilation and drainage.

4. How to install Trex decking with hidden fasteners?

Installing Trex decking with hidden fasteners requires some specialized tools and techniques, but it is generally straightforward and can be done with basic DIY skills.

First, you need to prepare the deck's substructure by ensuring that the joists are level, the spaces between them meet the manufacturer's recommendations, and the deck frame is securely anchored to the ground. Then, you can start installing the deck boards by aligning the first board with the deck's edge and securing it with Start Clips or screws.

After that, you can insert the Universal Hidden Fasteners into the grooves of the first board perpendicular to the joists and secure them to the joists with screws. Then, you can repeat the process along the remaining boards, ensuring that the gap between boards is consistent and the fasteners are aligned.

Finally, you can trim the excess board overhang, cover the board ends with Trex End Coating or Fascia, and enjoy your new Trex deck with hidden fasteners!

5. Conclusion

Trex decking with hidden fasteners is a popular and practical choice for homeowners who want a beautiful and safe deck without visible fasteners. The width of Trex decking boards can vary depending on the line and the installation method, and the gap size between boards can affect their appearance and performance.

Therefore, it is essential to choose a Trex decking line that suits your aesthetic and functional preferences, follow the manufacturer's guidelines for joist spacing, gap size, and installation, and use proper tools and techniques to ensure top-quality results. With Trex decking and hidden fasteners, you can enjoy a worry-free and long-lasting outdoor living space that enhances your home's value and appeal.
