Key Takeaways

Materials and Durability of TimberTech and Trex Composite Decking

We delve into the difference in materials used by TimberTech and Trex for their composite decking, discussing how each material’s durability reacts to Washington State’s weather.

Comparison of materials used

Regarding the materials used in TimberTech and Trex decking, several key differences can be noted. These differences play a significant role in the overall durability and longevity of your deck.

Features TimberTech Trex
Core Material Polyvinyl Chloride (PVC) Recycled wood and plastic blend
Capping Fully capped on all four sides Capped only on three sides
UV Resistance Highly resistant due to PVC and full capping Less resistant due to partial capping and use of recycled materials
Eco-friendliness Low due to use of PVC, which is not easily recyclable High due to the use of recycled wood and plastic

As you can see, the materials used in TimberTech and Trex decking differ significantly. TimberTech utilizes PVC and fully caps its boards, which enhances UV resistance.
However, this comes at the cost of reduced eco-friendliness.

On the other hand, Trex uses a blend of recycled wood and plastic, which makes it more eco-friendly.

However, its capping on only three sides makes it less resistant to UV rays, potentially affecting its longevity.

Impact of Washington State's Weather on Durability

Washington State has heavy rain, snow, and sun. These can make the deck color fade fast and cause cracks and warps over time. This harms the deck’s look and safety.

Both brands stand up to such weather well, but not forever.

TimberTech Vs Trex Warranty

TimberTech and Trex both offer limited warranties to protect your investment. The warranties cover issues that arise due to manufacturing defects and are fairly comprehensive.

Here’s how the warranties for the two brands stack up:

In addition to these, TimberTech also offers a 50-year and lifetime warranty for their AZEK PVC decks.
Brand Product Line Warranty Offered

TimberTech Legacy 30 years
Trex Lineage 50 years
Trex Transcend 25 years

Both TimberTech and Trex decking can stand up to Washington State’s weather pretty good, but one has a particular edge.

TimberTech’s capping on all 4 sides keeps water and dampness away from the core of the board. Even if water somehow penetrates the surface layer (or the capping), it reaches a PVC core that does not rot.

With Trex, water can reach the core easier through the only side that remains uncapped, and because its core is made of recycled wood, the board can actually rot and lose its some of its quality.

Besides, the longer warranty that TimberTech offers and the line of AZEK PVC decks make us say that TimberTech is better for the environment in Washington State.
