Understanding Window Frame Materials: Vinyl vs Aluminum Windows Basics

Choosing between vinyl and aluminum windows starts with understanding each material. Let's break down what makes them different.

What Are Vinyl Windows?

Vinyl windows are made from PVC (polyvinyl chloride). It's the same plastic used in pipes. Manufacturers heat and mold PVC pellets into window frames. They add UV stabilizers to prevent fading.

These windows dominate residential markets today. Why? They're affordable and energy-efficient. You'll find them in:

- Single-family homes

- Apartments

- Townhouses

- Budget-conscious renovations

What Are Aluminum Windows?

Aluminum windows use lightweight metal frames. Manufacturers extrude aluminum into shapes, then apply finishes. Popular coatings include:

- Powder coating for durability

- Anodization for corrosion resistance

- Painted finishes for color variety

They're common in:

- Commercial buildings

- Modern homes

- Storefronts

- High-rise apartments
