Why Your Upper Deck is a Heat Trap
On a 90-degree day, a wood or composite deck surface can reach temperatures of 140 degrees Fahrenheit. This creates a “convection dome” that makes the air above the deck stifling. Homeowners often find themselves trapped inside, looking at a beautiful backyard they can’t actually enjoy.
The “Canopy Effect”
The space under your deck is naturally shaded, but without a ceiling, it remains humid and prone to “radiant heat” from the deck boards above. A BuildRT aluminum system creates a thermal break.
- Reflection: Our powder-coated aluminum reflects radiant heat away from the living area.
- The Pitch Advantage: Our ceilings are engineered with a precise pitch to ensure water is continuously evacuated. This design prevents moisture buildup and helps maintain a crisper, less humid environment under the deck.
- Active Cooling: A dry ceiling allows for the installation of high-RPM outdoor ceiling fans. Because the air is already shaded, the fan’s “wind-chill” effect can make a 95-degree day feel like a comfortable 80.
The Luxury of 10-15 Degrees
Think of an underdeck as a “natural air conditioner.” It is the only place in your yard where you can enjoy the breeze without the UV exposure. For families with children or pets, it provides a safe “cool zone” for all-day outdoor play.
Conclusion: Be cool and be outdoors
Just because it’s warming up outside, doesn’t mean you have to run indoors and turn on the A/C. With our RainTight Underdeck system, you can stay cool and be outside no matter the temperature. Download the deck dimension sheet to get started.
