Hung windows, coordinated grids and proportions that preserve the home’s architecture.
Large picture units, casements, dark frames and simplified grid patterns—subject to size and performance limits.
Glass construction, sash seals, frame design and installation selected together; laminated glass may help where available.
The product with clear specifications, professional installation, usable warranty support and a price appropriate to the performance.
Read the label
Compare measurable performance.
Look beyond “energy efficient.” Compare NFRC-rated U-factor, solar heat gain coefficient, visible transmittance and air leakage when available. Then confirm the exact glass package on the order.

SHGCHow much solar heat passes through. Lower values are often favored for strong North Texas sun exposure.
Air LeakageHow much air passes through the product under test conditions. Installation still matters.
Visible TransmittanceHow much visible light comes through the glass package.
