Texas summers are long and hot, which makes energy efficiency a top concern when choosing replacement windows.

Features of Energy-Efficient Windows

• Double or triple-pane glass – Helps insulate against heat transfer.

• Low-E coating – Reflects infrared light to keep interiors cooler.

• Gas fills (argon or krypton) – Improve insulation between panes.

• Insulated frames – Vinyl and fiberglass frames reduce air leakage.

Best Window Materials for Texas Homes

• Vinyl – Affordable and efficient, good for most homeowners.

• Fiberglass – More durable and insulates better.

• Wood-clad – Excellent insulation but higher maintenance in humid areas.
