Fiberglass vs Polyester Screen: Is It Worth the Extra Cost?

Written By Kenneth Wilson  |  4 Comments

Fiberglass screen is the most common type of screen used for enclosures, but polyester screen has several advantages. Since polyester screen is more expensive, the question becomes: is the difference worth the extra cost? Either kind serves a purpose and, depending on your goals, may be the right screen for your home.  When it comes to polyester screens, there are currently 3 brands all producing a VERY comparable mesh (we believe they are all manufactured in the same facility and just get their own brand packing), Ultrascreen, Superscreen and Tuff Screen.


Polyester mesh is incredibly strong. In fact, it’s over 100% stronger than standard American-made fiberglass screen. According to information published online by Super Screen, a brand of polyester screen, the warp tensile strength of fiberglass screen is only 78.8 pounds force, while that of their product is 112.5 lbf. They list the warp tear strength as 14.0 lbf and the fill tear strength of fiberglass screen as 9.9 lbf, but Super Screen as 31.5 lbf for warp and 27.2 lbf for fill. The ball burst strength of Super Screen is also impressive at 188 lbs, compared to only 61 lbs. for fiberglass screen. Ultra-Screen, another polyester screen, has 141.6 tensile warp strength, 151.8 tensile fill strength, and 268.0 psi burst strength.

***Side note on strength: Initially both screens are ‘strong’, albeit the fiberglass not nearly as strong as polyester, but not a ‘weak’ material.  HOWEVER, as the materials age under the Florida sun the fiberglass materials quickly deteriorate and lose their original strength and color.


The warranty for polyester Super Screen is a full ten years, although tests have shown it can last over twice as long. UltraScreen polyester mesh also has a ten-year warranty. Fiberglass screens don’t last as long, and so don’t have this type of warranty. This means that, while you will typically need to rescreen your pool cage, screen lanai or screen room within a few years of installing fiberglass screen, you shouldn’t have to put on new screen for a very long time if you choose polyester screen in the first place.

No See Ums

Neither standard 14/16 polyester screen nor standard 18/14 fiberglass screen keeps out small bugs like no see ums. Most Florida residents who have been in the state for years are quite used to these critters and may not even notice them anymore. However, if you’re new to Florida and unaccustomed to the itchy nuisance of no see ums, you might prefer the 17/20 polyester mesh or 20/20 fiberglass mesh. Its holes are so small that even these tiny, nearly-invisible bugs can’t get through.


Once you invest in a screen enclosure, you’ll want to keep it clean and in good repair. Powerwashing is a great way to keep your screen clean, but you can’t use that method on fiberglass screen after a few years. But, you can always powerwash polyester screen as long as you have it.

If the screen does tear and you need a panel replaced here and there, you will have to pay a higher price and usually a service call charge for replacement. With a Polyester screen such as UltraScreen or Super Screen, however you’re much less likely to need to do it (get a service call for repair).  Recall from the first paragraph, that the polyester screens are much stronger, and the fiberglass weaken with exposure to the elements.  After a couple years, a strong gust of wind, power washer, or weed whacker could easily tear the fiberglass material.

Color Changes

Fiberglass tends to change colors very quickly. Polyester screen, on the other hand, never does. This increases its long-term visual appeal over fiberglass. You should never have to rescreen due to color changes after screening with UltraScreen or Super Screen polyester materials, but you might if you’ve used fiberglass and want to maintain its appearance.

Bottom Line

So, which screen should you buy? Should you pay more for the advantages of polyester screen? The most important factor in your decision about which screen to use is how long you plan to own your home.

If you only plan to spend a few short years in your current home, you may want to use the less expensive fiberglass screen. You can choose between a standard 18/14 fiberglass mesh or a 20/20 no see um fiberglass mesh. The strength won’t matter as much unless there’s a storm severe enough to damage it. You won’t be able to powerwash it after a few years, but that’s okay if you don’t plan to be there very long.

On the other hand, if you intend to make this house your forever home, you’ll want the better polyester screen that lasts longer, has a longer warranty, is stronger, and is easier to maintain. For you, getting the better product is well worth the additional cost. You’ll have a stronger, longer-lasting screen enclosure that stays beautiful for many years into the future.

About the Author

I can build it, and I can help you get the patio enclosure you want! I got my start in the Florida patio industry back in the 70s as a young general laborer looking for something to make a few bucks. At the time I never thought it would end up as my career. Over the years I grew beyond the laborer position, becoming a foreman, superintendent, and then into executive management for some of the largest patio contractors, and material vendors. Now into retirement and slightly bored, I offer consulting services to new and existing contractors, and publish this website to help the people who love their patio's and screen enclosures the most - YOU!

  • Many thanks for the truly unbiased information that you’ve shared. As a snowbird, mechanical engineer, I am greatly appreciative of the details and explanations that you’ve provided. As I look to spend overt $20k to replace my pool enclosure that was destroyed by Irma, I feel much more confident in making an informed decision and getting a quality product that meets my expectations thanks to the information you’ve shared.

  • Thanks for explaining that choosing to invest in a polyester screen means we won’t have to replace it for a very long time. My husband and I are thinking of having a screen lanai added to our home so we can have a relaxing place to hang out and not worry about bugs. I’m glad I read your article because I feel a lot more informed and prepared to shop for the right kind of screen to buy!

  • Thanks for mentioning how a polyester screen can be power washed for a while. I’m wanting to install a screen in our backyard where we can sit out and not be bitten by bugs. I will have to find a good mesh screen that will last a good amount of time.
