Why We Recommend Alside

After installing thousands of windows in Houston, these are the details that matter.

01

Vinyl That Holds Up

Cheap vinyl can warp in Houston heat. Alside uses virgin vinyl compounds with UV inhibitors engineered for temperature extremes.

The build: Multi chambered frames with fusion welded corners for a tight, durable seal.

02

Glass Packages That Work Here

Glass performance drives comfort. Alside commonly pairs Cardinal Low E 366 with argon fill and warm edge spacers to cut solar heat gain.

Houston target: U Factor at or below 0.30, SHGC at or below 0.25

03

Warranty That Is Actually Usable

Warranties only matter if claims are handled. Alside has been around for decades and the coverage is clear on the major parts that typically fail first.

Common coverage: Frame, sash, insulated glass, hardware, screens.
