Trex Decking Thickness For Durability

Choosing the right Trex decking thickness is crucial. Durable decks resist wear, weather, and time. Trex decking combines longevity with comfort.

Trex decking comes in two profiles: grooved and square-edged. Each offers unique advantages and suits different styles.

  • Grooved boards are perfect for hidden fastening systems.
  • Square-edged ones are for traditional top-down fastening.

Impact Of Profile Choices On Installation

The profile of Trex boards affects installation. Here’s what to consider:

Profile Type Installation Method Tool Requirement
Grooved Hidden fasteners clip into side grooves. Specialist tools may be required.
Square-Edged Screws directly on top of deck boards. Standard decking tools will work.

Choice of profile also determines project time and cost. Grooved profiles can save time but may need additional investment in fasteners and tools.
