Our summers are brutal on garage doors — a west-facing door bakes for hours, and a bare steel panel passes all that heat straight into the garage. Here's what actually holds up and keeps you comfortable.
Material: steel (or faux-wood)
Steel doesn't warp, crack, or fade the way wood can under the Texas sun, and it needs almost no upkeep. If you want the wood look, faux-wood composite gives you the same heat tolerance. Real wood is doable but demands regular refinishing out here.
Insulation: polyurethane, non-negotiable for attached garages
A polyurethane-insulated door (R-12 to R-18) is the single biggest thing you can do to fight the heat — it slows the temperature swing and eases the load on your AC. Here's the full worth-it breakdown, and the best insulation compared.
Color: go lighter
Dark doors look sharp but absorb more heat; lighter colors stay noticeably cooler in direct sun. If your door faces west or south, lean lighter.
Put it together
Insulated steel, lighter color, quality weather seals. Build that exact door for your opening in our designer, or let us install it — we'll help you pick the right R-value without overselling.
Key takeaways
- Best combo for Texas: insulated polyurethane steel in a lighter color.
- Steel (or faux-wood) resists the heat damage that hurts real wood.
- Polyurethane insulation (R-12 to R-18) is the biggest heat-fighter.
- Lighter colors run cooler than dark ones in direct sun.
- For an attached garage, insulation is the upgrade that pays off every summer.
