Metal, Fiberglass or Polyester Insect Screen: What’s the Difference and How to Choose?

When selecting a screen for your windows or doors, the material plays a crucial role in durability, performance, and appearance. The three primary materials used in screen manufacturing are fiberglass yarn, metal wire, and polyester yarn. Each offers its own set of advantages depending on your specific needs and environment.

So, how do you decide which one is best for your home or project? Read on to explore the differences and make an informed choice!

What’s the Difference?

The earliest insect screens were made from metal, so let’s start there. Metal screens, most commonly manufactured from aluminum, are a traditional and durable choice. Their strength makes them ideal for areas where insects like grasshoppers or other pests might chew through softer materials.

In addition to their durability, metal screens often provide a clearer, more visually appealing view compared to other types. Beyond aluminum, metal screens can also be made from bronze, stainless steel, or galvanized steel wire, each offering its own level of corrosion resistance and aesthetic appeal.

Fiberglass and Polyester Screens: Modern Alternatives

Fiberglass screening was introduced in the late 1960s and quickly gained popularity for its flexibility and resilience. Coated with a protective vinyl layer, fiberglass offers a durable, corrosion-resistant solution, making it especially well-suited for coastal environments. Unlike metal, it won’t rust or corrode, even in humid or salty air. Over time, fiberglass has become a top choice for pool enclosures, patios, and screened porches. It’s typically available in charcoal or gray, colors chosen for their ability to reduce glare and maintain visibility.

In the early 1980s, Phifer pioneered the use of polyester fabrics for outdoor furniture with its Phifertex® product line. The material’s strength, durability, and weather resistance made it ideal for harsh outdoor conditions. These polyester-based options are now widely used in homes and commercial spaces for their specialized performance and extended lifespan.

Choosing the Right Screen Material: Fiberglass, Metal, or Polyester

When selecting a screen material for your windows, doors, or enclosures, it's important to understand the differences between the most common options: fiberglass yarn, metal wire, and polyester yarn. Each material offers unique advantages depending on your project’s requirements. So, how do you decide which one is best for your home or commercial space? Read on to learn more!

What’s the Difference?

Metal Screens

Metal was the original material used in insect screens and remains a traditional choice today. Aluminum is the most common metal used, valued for its strength and durability. Metal screens are especially ideal in areas with large or aggressive insects, like grasshoppers, which can damage weaker materials.

Other available metal options include bronze, stainless steel, and galvanized steel wire, each offering unique benefits in strength, appearance, and corrosion resistance. Metal screens often provide a clearer viewing experience and a more classic look.

However, they are less forgiving than other materials and can dent or deform if bumped. This rigidity makes them less suitable for DIY installations and more appropriate for professional handling.

Fiberglass Screens

Introduced in the late 1960s, fiberglass screening quickly became popular for its flexibility and resistance to corrosion. Coated with a vinyl protective layer, it performs particularly well in coastal climates, where humidity and salt can accelerate metal corrosion.

Fiberglass is commonly used for pool enclosures, patios, and screened-in porches, thanks to its lightweight nature and ease of handling. It's generally available in charcoal or gray for a subtle, modern look. Its flexibility also makes it more resilient to impact, making it ideal for homes with children or pets.

Polyester Screens

The key difference lies in how polyester yarns are coated. While metal screens are painted after weaving and, fiberglass yarns are liquid-coated before weaving, polyester yarns are vinyl-coated through an extrusion process. This method applies more vinyl, resulting in a thicker, softer, and more durable yarn, ideal for high-traffic areas, pets, and extreme conditions.
