At our window and door stores across the Southwest, one question comes up almost daily: "Are vinyl windows a good choice for our climate?" The short answer? Yes—and here's why.

The Truth About Vinyl Windows in the Southwest

When vinyl windows first entered the market, particularly in hot, arid climates like ours, many were made from recycled materials without proper UV protection. As a result, early versions would warp, crack, or fade under intense sun exposure. Unfortunately, this outdated reputation still lingers today.

But the truth is, modern vinyl windows are a completely different product—built with UV inhibitors, stronger materials, and fusion-welded frames that outperform many other options in durability, insulation, and longevity.

Vinyl vs. Aluminum Windows: What’s the Difference?

We sell both vinyl and aluminum windows, and both have their place. Here’s a quick comparison:

Aluminum Windows

• Available in popular colors like bronze

• Strong, durable frame material

• Still widely used in many home styles

• Screwed together and sealed with silicone (can allow more air and dust penetration)

Vinyl Windows

• Fusion-welded for airtight performance

• Up to 20% more energy-efficient than aluminum

• Doesn’t conduct heat or cold as much—better insulation year-round

• Low-maintenance and resistant to fading, cracking, and warping

• Now available in painted finishes, including bronze, through brands like Milgard and Alside

Note: Most painted vinyl options have a white interior, which some homeowners may want to consider when designing their space.

Energy Efficiency and Long-Term Value

Vinyl windows offer substantial energy savings, which is crucial in both hot and cold climates. Because they don’t conduct heat the way aluminum does, they help maintain consistent indoor temperatures and reduce HVAC costs.

As energy codes continue to evolve, even thermally broken aluminum windows may struggle to comply. Vinyl, with its superior insulation, is well-positioned to meet future standards and remain a go-to for new construction and window replacements.

Built to Last—with Warranties to Prove It

Top manufacturers back their vinyl windows with limited or full lifetime warranties, reinforcing their durability and long-term value. If vinyl windows were prone to failure today, the entire industry—including us—would be facing massive warranty claims. Instead, vinyl windows have become the reliable standard for performance, affordability, and peace of mind.

Don’t Be Afraid to Make the Switch

Today’s vinyl windows are not the same product they were decades ago. With advanced manufacturing, better materials, and expanded color options, vinyl windows now offer the perfect balance of form and function for homes across the Southwest.
