Plus, Trex Transcend Lineage uses heat-mitigating technology that makes it our coolest decking yet.*

*Although Trex Transcend Lineage is designed to be cooler than most other composite decking products of a similar color, on a hot sunny day, it will get hot. On hot days, care should be taken to avoid extended contact between exposed skin and the deck surface, especially with young children and those with special needs.

These decking lines should not be combined to avoid tripping hazards.
