How Picture Windows Handle Texas Heat
Picture windows get a reputation for being simple, but that simplicity is part of the reason they can perform well in Texas heat.
A fixed window has no sash to slide, no crank to wear out, and no gaps that open and close every season.
In other words, the shape helps, but the performance comes from the whole assembly.
What Actually Determines Energy Efficiency
The fixed style gives picture windows a head start, but the glass package and frame decide how much solar heat gets through.
For hot Texas conditions, a lower SHGC is usually better because it allows less solar heat to pass through the glass.
U-factor matters too.
