Exterior wood products are the biggest concern. Wood siding, cladding, and front doors will split, warp, and crack in the Las Vegas climate — a wood front door with west exposure can deteriorate within two to three years. The issue is the extreme temperature swing between day and night, and between summer and winter. That constant expansion and contraction causes wood to move, creating gaps that lead to water intrusion and structural damage. Aluminum alternatives that replicate the look of natural wood are a durable solution and are nearly indistinguishable from real wood at a distance.
