California Title 24 Windows | Energy Code Compliance for Homeowners

Learn what California Title 24 window requirements mean for homeowners and how to stay compliant with energy efficiency standards.

What Is Title 24?

Title 24 is California’s Building Energy Efficiency Standards. It sets rules for new construction and remodels to ensure homes use less energy and reduce environmental impact.

How It Affects Your Windows

To meet Title 24, replacement windows must meet certain ratings:

• U-Factor – Measures insulation. Lower numbers mean better energy efficiency.

• Solar Heat Gain Coefficient (SHGC) – Measures how much solar heat passes through. Lower SHGC = cooler homes in hot areas.

• Visible Transmittance (VT) – Balances natural light with energy performance.

Why Compliance Matters

• Keeps your home up to code during remodels.

• Lowers utility bills through energy-efficient designs.

• Makes your home more comfortable year-round.
