What 115° actually does to backyard materials
Phoenix surface temps regularly hit 160–170°F on dark hardscape in July. Most material warranties were written for milder climates. Here's the AZ-specific heat index AE uses to spec every job.
- 01
Dark concrete pavers: 165°F+ midday — choose lighter color blends in barefoot zones.
- 02
Travertine: stays 20–30° cooler than concrete. AE's default for pool decks and barefoot patios.
- 03
Standard turf with silica infill: 175°F+ surface. Cool-fill drops it 30–40°.
- 04
Composite decking: warps and discolors above 140°F. AE doesn't spec it for AZ sun exposure.
- 05
Stainless steel hardware: powder-coat or marine-grade only — consumer hardware oxidizes in 18 months.
