20x20 No-See-Um Screen Mesh for Pool Enclosures

20x20 screen mesh is a popular upgraded screening option for Florida homeowners who want additional protection from small insects without giving up the open-air feel of a screened enclosure.

At Lafferty Aluminum & Screening, we install 20x20 screen mesh on pool enclosures, patios, lanais, front entryways and foyers, screen rooms, porches, and other residential screen enclosures throughout Brevard and Indian River Counties.

Often called no-see-um screen, 20x20 mesh has a tighter weave than standard 18x14 screen. That smaller opening helps reduce the number of tiny insects entering your enclosure, making it particularly useful for homes near water, wooded areas, canals, retention ponds, and other areas with high insect activity.

What is a 20x20 Screen Mesh?

The term 20x20 screen refers to the mesh count: approximately 20 openings per inch horizontally and vertically.

Compared with standard 18x14 screen mesh, the tighter weave creates smaller openings in the screen. This helps block smaller insects, including no-see-ums, gnats, mosquitoes, and other pests that may be able to pass through larger screen openings.

Because of its tighter construction, homeowners should also understand that 20x20 mesh can provide slightly less airflow and visibility than standard 18x14 screening.

The right choice ultimately depends on what matters most for your outdoor space.

Where Can 20x20 Screen Mesh Be Used?

One advantage of 20x20 mesh is its versatility. It can be installed on many types of residential screened structures.

We commonly install 20x20 screen on:
Pool enclosures and pool cages
Screened patios
Lanais
Screened porches
Front entryways and foyers
Screen rooms
Existing enclosures being rescreened
Other custom screen enclosures

It can be selected for a new enclosure or used when replacing the screen on an existing structure.

Benefits of 20X20 Mesh is Insect Protection

Better Protection From Small Insects

The primary reason we recommend 20x20 mesh is insect protection.

Standard screening does a good job of keeping out common mosquitoes, flies, and larger insects. However, very small insects such as no-see-ums can require a tighter mesh.

This is particularly relevant in Brevard and Indian River Counties, where many homes are located near the Indian River Lagoon, canals, retention ponds, marshes, wooded areas, and other environments where small insects can be especially noticeable.

A Good Option for Pool Enclosures

20x20 mesh is a popular upgrade for pool enclosures because pools are often used in the early morning and evening — the same times homeowners may notice increased insect activity.

The tighter mesh allows homeowners to maintain a screened outdoor environment while adding another level of protection against smaller pests.

Suitable for Patios, Lanais and Porches

You don't need a pool to benefit from no-see-um screen.

20x20 mesh can also be installed on screened patios, lanais, porches, and other outdoor living spaces. If you regularly use your patio for eating, entertaining, relaxing, or spending time outside in the evening, additional insect protection can make the space more comfortable.

Great for Screened Front Entryways and Foyers

20x20 screen is also an option for screened front entrances and foyers.

A screened entryway can allow homeowners to open their front door for ventilation while maintaining a screened barrier between the entrance and outdoors. A tighter mesh can be particularly useful when small insects are common around the property.

Slightly More Daytime Privacy

The tighter weave can make 20x20 screen appear somewhat darker and provide slightly more visual privacy during daylight hours than standard 18x14 mesh.

However, we don't recommend choosing 20x20 mesh solely as a privacy product.

It is still screen, and people may be able to see through it. Visibility also changes depending on lighting conditions. At night, for example, lights inside the enclosure can make the interior much easier to see from outside.

Homeowners looking specifically for increased privacy should discuss other screening options designed for that purpose.

20x20 vs. 18x14 Screen Mesh

One of the most common questions we receive is whether a homeowner should choose 18x14 or 20x20 screen mesh. We typically recommend 18x14 mesh when homeowners prioritize maximum airflow, visibility, and standard insect protection.

We typically recommend 20x20 mesh when smaller insects are a recurring problem and the homeowner is comfortable trading a small amount of airflow for additional insect protection.

Neither option is automatically better. The best screen depends on the property and how the enclosure will be used.

Does 20x20 Screen Reduce Airflow?

Yes, there can be a difference.

Because 20x20 screen has a tighter weave, less open area is available for air to pass through compared with a more open screen mesh.

For many homeowners, the difference is an acceptable tradeoff for improved protection from small insects. However, someone whose number-one priority is maximizing breeze and visibility may prefer standard 18x14 mesh.

This is why we recommend considering insect activity, airflow, visibility, location, and how you use the enclosure rather than automatically choosing the tightest screen available.

Does 20x20 Screen Make an Enclosure Darker?

A tighter screen mesh can make an enclosure appear somewhat darker than standard screening because there is more screen material within the same area.

The difference can depend on the size of the enclosure, surrounding landscaping, orientation of the home, and available natural light.

For homeowners who value an extremely open view above everything else, this is another factor worth considering before selecting 20x20 mesh.

When Might 20x20 Screen NOT Be the Best Choice?

20x20 isn't automatically the best screen for every Florida home.We may recommend comparing it with other screen options if your biggest priority is:
Maximum airflow
The clearest possible outward view
A more open screen appearance
Dedicated privacy rather than insect protection
Increased resistance to damage from pets
A specialized screening application

For example, homeowners concerned about pets may want to compare a pet-resistant screen, while someone primarily concerned about privacy may benefit from a screen specifically designed for that purpose.The best mesh is the one that matches the purpose of the enclosure.

Our Recommendation on 20x20 Screen Mesh

At Lafferty Aluminum & Screening, 20x20 screen mesh is one of the most popular upgraded screen options homeowners choose for additional insect protection. We commonly recommend it for homes located near water, wooded areas, retention ponds, marshes, or areas where no-see-ums and mosquitoes are more active.

Compared to standard 18x14 screen mesh, the tighter 20x20 weave helps block smaller insects that can sometimes pass through traditional screen openings. Many homeowners notice a major difference in comfort, especially during early mornings and evenings when bug activity is highest.

In our experience, 20x20 mesh is especially popular for:
Pool enclosures
Lanais
Patios near canals or water
Homes near the Indian River Lagoon
Outdoor spaces used frequently at sunset
While 20x20 provides improved insect protection and slightly more daytime privacy, homeowners should also know the tighter mesh can slightly reduce airflow compared to standard 18x14 screens.

During our estimate process, we help homeowners compare both screen options based on:
Bug activity
Airflow preferences
Privacy goals
Visibility
Budget
Outdoor usage
We believe the best screen choice depends on how you actually use your outdoor living space.

Can You Replace Existing Screen With 20x20 Mesh?

In many cases, yes.If you already have a pool cage, patio enclosure, lanai, porch, or other screened structure, 20x20 mesh may be an option when replacing damaged or aging screening.

Depending on the condition of the existing enclosure, homeowners may need individual screen panel replacement or more extensive rescreening. The condition of the aluminum framing, spline channels, fasteners, doors, and other enclosure components should also be considered when evaluating an older enclosure.

Frequently Asked Questions (FAQ)

Does 20x20 screen mesh really keep no-see-ums out?

20x20 screen mesh is designed with smaller openings than standard 18x14 screen, making it a popular choice for reducing no-see-ums and other very small insects.

No screened enclosure can guarantee that every insect will be eliminated, but a tighter mesh can provide substantially better protection from small insects than a more open screen.

Is 20x20 screen the same as no-see-um screen?

20x20 mesh is commonly referred to as no-see-um screen because its tighter weave is intended to help prevent very small insects from passing through.

Specific screen products can vary by manufacturer, so homeowners should consider the actual mesh specifications of the product being installed rather than relying only on a product nickname.

Is 20x20 screen mesh worth the upgrade?

It can be, particularly if small insects are interfering with how often you use your screened outdoor space.

For homes with minimal no-see-um activity, standard screen may provide everything the homeowner needs. For properties near water, woods, marshes, or other high-insect environments, the tighter mesh can make the upgrade much more valuable.

Is 20x20 screen good for a pool enclosure?

Yes. Pool enclosures are one of the most common applications for 20x20 mesh, particularly when the property experiences significant mosquito or no-see-um activity.
