Vinyl (PVC) vs. uPVC Windows: Understanding the Key Differences

When choosing new windows and doors for your home or project, understanding the differences between vinyl (PVC) and uPVC windows is crucial. Many homeowners and builders assume they are the same, but they have significant differences in durability, energy efficiency, and overall value. If you’re considering replacement windows, this guide will help you make the right choice.

What Are Vinyl and uPVC Windows?

Before diving into the differences, let’s define what each material is:

• Vinyl (PVC) Windows – Made from polyvinyl chloride (PVC) with added plasticizers to increase flexibility.

• uPVC Windows – Short for unplasticized polyvinyl chloride, this material does not contain plasticizers, making it more rigid, durable, and resistant to environmental factors.

At Windows Online, we specialize in high-quality uPVC windows, known for their superior durability and energy efficiency compared to common vinyl windows available through the local manufacturers in Canada.

Key Differences Between Vinyl (PVC) and uPVC Windows
