SCREENING FOR INSECT CONTROL

Selecting Mesh for Insect Control:

• Choose screens with smaller openness factors for maximum insect control (high warp, fill, and yarn diameter).
• Consider compromises: smaller openness factors reduce airflow and light transmittance.

Optimal Mesh Choices:

• For air movement: consider 20X20 mesh.
• For maximum airflow: 18X14 mesh is ideal.
• For nighttime insect control with lights: use 20X30 mesh and fans.

SCREENING FOR SUN CONTROL

Solar Transmittance and Reflectance:

• Tighter weaves reduce solar transmittance and increase solar reflectance.
• Lighter colors enhance reflectance, while darker colors increase absorbance.

Managing Solar Absorbance:

High absorbance can lead to re-radiation of heat into the room. Aim to maximize reflectance and minimize absorbance to improve sun control.

Compromises:

• Reducing openness factor lowers transmittance but may affect airflow.

SCREENING FOR PRIVACY CONTROL

Privacy Mechanism:

• Functions like one-way mirrors; darker side sees through to the lighter side.
• Light screen colors improve daytime privacy for darker interiors.

Nighttime Privacy:

• Lit interiors become visible from outside, while outside observers can see inside.

Factors Affecting Privacy:

Higher reflectance on the lighter side enhances privacy for the darker side. Visual transmittance matters: lighter colors and lower transmittance improve privacy.

Balance Between Characteristics:

• Consider semi-open meshes (like white Solar screen) for a compromise between light and privacy.
