It’s the summer of 2024, and the Kern family in Duncanville Texas were looking to update an old DYI deck/patio that the prevous homeowner had installed. The old deck surface was installed using tile and rock board and it was not only falling apart, it was unsafe.
When the Kern family began their quest for the ideal decking for their Texas home, they knew their wish list was ambitious: waterproof, low maintenance, and exceptionally durable. They wanted not just a beautiful outdoor deck, but also a dry, usable patio space underneath.
The Kern Family Goals:
- Install some type of decking system that would allow the use of the lower patio during bad weather as well as, provide some shade.
- Low maintenance and durability in the Texas heat were top prioreties.
- Clean up, paint and reinstall the existing deck railing.
- Reinforce or rebuild the esisting deck structure for long term durability.
The Challenge: True Waterproofing
Their first options were the usual suspects: cedar, pressure-treated lumber, and composite decking. While classic woods like cedar are beautiful, they require constant upkeep and falter over time when exposed to weather. Pressure-treated wood lasts a bit longer but still needs regular staining and sealing, and it isn’t truly waterproof.
Composite decking held great promise for low maintenance and durability. However, even the best composite systems rely on gaskets or secondary membranes for waterproofing. The Kerns weren’t convinced these would keep their lower patio reliably dry for years—water always finds a way through seams or failed gaskets. For them, the ability to confidently keep the patio below dry was non-negotiable.
The Solution: Nexan LockDry Aluminum Decking
After further research, they discovered aluminum decking—specifically, the LockDry system from Nexan. This product stood out because its design creates a seamless, watertight surface when installed. There are no exposed fasteners, no seams to fail, and no gaskets to wear out or leak. When used on a second-level deck, LockDry gives you a truly dry patio area below, instantly expanding your living space regardless of the weather.
Why Nexan LockDry?
-
Zero Maintenance: The powder-coated aluminum never needs painting, staining, or sealing, and it won’t rot, crack, or warp. You save time and money every year on upkeep.
-
Watertight System: Its unique interlocking design means water simply runs off, never penetrating below. The patio underneath stays dry for storage, entertaining, or whatever your imagination dreams up.
-
Strong & Lightweight: LockDry supports up to 240 pounds per square foot—far beyond the strength of wood, but weighing half as much.
-
Fireproof & Non-Combustible: Aluminum is completely fireproof, making it ideal for hot Texas summers and areas prone to wildfires.
-
No Fading or Warping: The UV-resistant powder coat stays beautiful for years, withstanding sun, rain, and the elements far better than composites or wood.
What About Nexan Aluminum Decking in Texas Heat?
The Kerns were understandably concerned: Would a metal deck get uncomfortably hot in the summer? Nexan had data comparing LockDry to other materials. Thanks to aluminum’s natural heat dissipation and reflective powder-coat finishes, LockDry stays as cool or cooler than most wood, PVC, and composite decks—even in extreme sun. Lighter-colored boards stay especially comfortable, but all benefit from the material’s ability to quickly shed heat. It’s recommended to allow airflow underneath the deck for even more cooling. The surface never gets hotter than standard decking, with the bonus of holding up flawlessly in both Texas heat and freezing winter cold.
“LockDry stays cooler than most composite decking products in extreme sun exposure… powder-coat finish reflects heat combined with the heat dissipation properties of aluminum. Aluminum construction will not absorb water, freeze, or crack, and withstands extreme heat and cold—from -400 to 400 degrees Fahrenheit.”
The Kern Family’s Result
Choosing Nexan LockDry brought peace of mind and transformed their outdoor area. The patio below is always dry. The deck never needs maintenance, resists the harsh Texas sun, and stays looking like new. The Kerns now enjoy a beautiful, functional space above and below—without worry.
