Choosing the right energy efficient windows La Porte TX homes need starts with understanding three key ratings. These numbers determine how well a window performs in Harris County Texas’s hot, humid Gulf Coast climate.
U-Factor measures how quickly a window loses heat. Lower is better. For La Porte, target a U-factor of 0.30 or below. Solar Heat Gain Coefficient (SHGC) measures how much solar heat passes through the glass. In Texas, you want SHGC ≤ 0.25 to block the intense summer sun. Visible Transmittance (VT) measures natural light, a higher VT keeps rooms bright without adding heat.
ENERGY STAR windows La Porte Texas must meet Zone 3 (South-Central) requirements: U-factor ≤ 0.30 and SHGC ≤ 0.25. Any window company La Porte TX you work with should be able to confirm these ratings before installation.
