 Fiberglass Replacement Windows

Fiberglass Is the Stronger, Higher-Performing Choice for North Texas Homes

What Are Fiberglass Windows?

Fiberglass frames are engineered to expand and contract at nearly the same rate as glass, so seals stay tight through North Texas’ extreme temperature swings without warping or cracking.

Every window is custom-measured to your home’s exact openings, and fiberglass’s added strength allows for slimmer frames and larger glass areas without sacrificing structural integrity. It is available in a wide range of factory-finished colors, in every style we install.

The Material Engineered to Outperform in Any Texas Summer

Fiberglass does the two things North Texas homeowners need most: it stands up to extreme heat without warping, and it holds its factory finish for years without ever needing to be painted or refinished.

At your consultation, we’ll show you exactly which fiberglass options fit your home and what they cost.

Pella fiberglass frames are engineered to expand and contract at nearly the same rate as the glass they hold, so seals stay tight and frames resist warping through the temperature ranges DFW homeowners actually deal with.
