When designing a building with natural lighting in mind, the type of light that enters through the roof can have a significant impact on functionality, comfort, and energy efficiency. In this regard, FRP (Fiberglass Reinforced Plastic) sheets play a critical role in controlling how light enters a space. But what’s the difference between direct and diffused light, and how do FRP sheets enhance both?

🔆 What is Direct Light?

Direct light occurs when sunlight passes through a translucent material without disruption or scattering. This form of lighting creates a strong beam of light focused on a specific area, making it ideal for tasks that require precision and visibility, such as:

• Painting and detailing workstations

• Workspaces where designers want clear visibility of the sky

• Environments where concentrated brightness is needed

Materials such as clear polycarbonate, acrylic, and glass are commonly used to achieve this type of lighting. However, direct light also has drawbacks. On sunny days, it can produce harsh shadows and glare, and it offers less ambient illumination in areas not directly hit by the light beam.

🌥️ What is Diffused Light?

Diffused light is the result of light passing through a material that scatters and spreads it, providing a softer and more even illumination across a larger area. This is where FRP translucent sheets truly shine.

Ideal for:

• Industrial and commercial buildings

• Warehouses and agricultural structures

• Sports facilities and public spaces

Diffused light is preferred in areas where a consistent and comfortable light level is more important than seeing outside. It minimizes shadows, reduces glare, and enhances visual comfort — contributing to safer and more pleasant work environments.

FRP sheets, particularly those made from glass-reinforced polyester, are excellent diffusers of light. They can be customized with opal or patterned finishes to adjust translucency and create the desired lighting effect. Polycarbonate and ultra-high impact (UHI) acrylic also serve well in diffused applications when appropriately treated.

🔧 Choosing the Right FRP Sheet for Your Lighting Needs

The decision between direct and diffused light should be based on your project's specific lighting requirements. If your space requires focused, task-specific lighting, consider materials that allow for direct light transmission. On the other hand, for general-purpose areas, especially in industrial or agricultural settings, diffused FRP sheets offer an ideal balance of natural light, durability, and energy efficiency.

✅ Why FRP?

FRP sheets are not only excellent light diffusers, but they also bring other benefits like:

• High strength-to-weight ratio

• Corrosion resistance in harsh environments

• Easy installation and low maintenance

• Customization in color, thickness, and translucency

Whether you're planning a greenhouse, warehouse, factory, or commercial space, FRP translucent sheets are a versatile and reliable solution for your roofing and cladding needs.
