Mesh vs Blockout Fabric for Zip Blinds: Which Should You Choose?

What is mesh fabric?

Mesh fabric, often called sunscreen fabric, is woven with tiny openings that allow some light and air to pass through. The openness factor controls how much visibility and airflow the fabric provides. A lower openness percentage usually gives more privacy and sun control. A higher openness percentage usually gives a better outward view.

Mesh is popular for zip blinds because it preserves the outdoor feeling of a patio. It reduces heat and glare without making the area feel like a closed room. This makes it ideal for alfresco dining, pool areas, balconies, pergolas, and outdoor sitting spaces where people still want light, breeze, and a view.

What is blockout fabric?

Blockout fabric is designed to stop much more light. It is usually denser and more private than mesh. In zip blind applications, blockout fabric can be useful where the sun is intense, the view is not important, or privacy is the main goal. It can also help create a stronger visual barrier for commercial spaces or side boundaries.

The trade-off is that blockout fabric changes the mood of the area. It can make a patio feel more enclosed and may reduce airflow. In some spaces, this is exactly what the buyer wants. In others, it may feel too heavy, especially during mild weather when the goal is comfort rather than complete shade.

Fabric comparison

Privacy during day and night

Privacy is one of the most misunderstood fabric features. During the day, darker mesh fabrics often allow people inside the patio to see out while making it harder for outsiders to see in. At night, if the patio lights are on and the outside is dark, visibility can reverse. People outside may see silhouettes or interior activity through the mesh.

Blockout fabric is more predictable for privacy because it does not rely on light balance in the same way. If privacy from neighbours is the main concern, blockout fabric or a very low openness mesh may be the better choice. A showroom demonstration with lighting can help buyers understand the difference.

Heat and glare control

Both fabric types can reduce heat and glare, but they do it differently. Mesh filters sunlight while keeping the space breathable. Blockout fabric stops more light and can be better for harsh western sun, outdoor screens, or areas where glare makes dining or working uncomfortable.

Color also matters. Darker mesh can improve view-through and glare control, while lighter colors may reflect more heat and blend better with light architecture. Blockout fabrics are more visually solid, so the color has a stronger design impact on the building exterior.

Best fabric by use case

For most patios, choose mesh. It gives the best balance of shade, airflow, and view. For balconies facing neighbours, consider low openness mesh or blockout fabric. For restaurants, mesh often keeps the dining area inviting while reducing sun and wind. For outdoor media areas, blockout fabric may be better because it controls light more strongly.

There is no universal best fabric. The right choice depends on sun direction, privacy needs, climate, view, and how the space is used. If possible, request large fabric samples and test them at the actual location. A small showroom swatch can look very different in full sunlight.

Maintenance should also influence the decision. Mesh fabric can collect dust within the weave, but it usually rinses and dries easily when cleaned correctly. Blockout fabric may show marks more clearly on some colors and can feel heavier when rolled. In coastal, dusty, or high-pollen areas, ask the supplier which fabrics are easiest to clean and which colors hide everyday marks best.

If two areas have different needs, mixing fabrics can be sensible. A west-facing side may need blockout fabric, while the garden-facing side may work better with mesh. Matching frame colors can keep the whole installation visually consistent even when fabric performance differs.
