Texas summers push exterior doors to their limits. With temperatures regularly hitting 100°F+ in Dallas, Houston, Austin, and San Antonio, your front door needs to handle extreme heat, UV exposure, and thermal expansion without warping, fading, or letting your AC bill skyrocket.
Iron Doors: Strength and Curb Appeal
Iron doors are the top choice for Texas luxury homes. Hand-forged iron with powder-coat finish resists fading, warping, and impact damage that destroys wood and fiberglass doors in Texas heat.
Best for: Homeowners who want maximum curb appeal, security, and a door that lasts decades.
Heat management: Pair with a thermal break frame and Low-E insulated glass to prevent heat transfer. Without thermal break, iron can conduct heat — so this upgrade is essential for south- and west-facing entries in Texas.
Aluminum Doors: Modern and Lightweight
Aluminum glass doors offer slim profiles and a contemporary look. They're lighter than iron, naturally resist rust, and won't warp in Texas humidity.
Best for: Modern and mid-century homes, commercial spaces, and anyone who wants maximum glass area with minimal frame.
Heat management: Aluminum conducts heat, so thermal break construction is important. Our thermal break aluminum doors have an insulating barrier built into the frame.
Fiberglass Doors: The Budget Option
Fiberglass doors are widely available at big-box stores and offer decent insulation. They can mimic wood grain and come pre-hung for easy installation.
Best for: Budget-conscious projects or rental properties where appearance is less critical.
Limitations: They fade and chalk in direct Texas sun within 5-10 years. They can't match the custom sizing, glass options, or visual impact of iron or aluminum. And they lack the security of a metal door.

Our Recommendation for Texas
For front entries, go with thermal break iron or aluminum — they handle the heat, look premium, and last. Save fiberglass for interior or low-visibility doors where custom fit isn't critical.
