Frequently Asked Questions​

What are Y12, Y15, and Y25 prismatic panels used for?

Y12, Y15, and Y25 prismatic panels are translucent plastic sheets designed to diffuse and control light. They are commonly used in skylights, light diffusers, ceiling panels, and architectural glazing. The prismatic pattern helps spread light evenly, reduce glare, and improve brightness in commercial, industrial, and residential spaces.

What is the difference between Y12, Y15, and Y25 prismatic panels?

The difference between Y12, Y15, and Y25 panels is the prism depth and light diffusion level. Y12 offers higher light transmission with lower diffusion, while Y25 provides stronger diffusion and glare reduction. Y15 sits between the two. Selection depends on lighting requirements and desired light spread.

What sizes and thicknesses are available for prismatic panels?

Y12, Y15, and Y25 prismatic panels are supplied in standard sheet sizes and 3mm and 4.4mm thicknesses suited to glazing and ceiling systems. Availability varies by pattern and material. Panels can often be cut to size to suit skylight frames, ceiling grids, or custom installations.

How are prismatic panels installed?

Prismatic panels are typically installed into aluminium frames, ceiling grid systems, or skylight assemblies. They should be properly supported to prevent sagging and allow for thermal expansion. Installation methods depend on sheet size, thickness, and whether the application is horizontal or vertical.

Are Y12, Y15, and Y25 panels suitable for outdoor use?

Suitability for outdoor use depends on the material and UV resistance. UV-stabilised acrylic or polycarbonate panels are commonly used in skylights and external glazing. Non-UV-stabilised panels may yellow or degrade over time when exposed to direct sunlight.

How durable are prismatic panels over time?

Prismatic panels are durable under normal lighting and glazing conditions. They resist moisture and corrosion and maintain light diffusion performance over time. Impact resistance and lifespan vary depending on material choice, thickness, and exposure to UV, heat, and weather conditions.
