What is a Diffuser?
A diffuser sits within the ceiling surround of your skylight, helping to distribute natural light evenly throughout the space. Some options also allow airflow where ventilation is required.
There are three main diffuser types:
OPAL DIFFUSER
Softens light and reduces glare, creating a smooth, even finish ideal for most residential spaces.
PRISMATIC DIFFUSER
Maximises and spreads light more sharply, delivering a brighter, crisper finish throughout the room.
GLOCELL DIFFUSER
Allows airflow while diffusing light, ideal for areas where ventilation and brightness are both important.

Need a Custom Size Skylight Diffuser?
If your diffuser is cracked, discoloured or damaged, Garron Skylights can supply custom-cut replacement panels to suit a wide range of existing skylights.
Many older systems use non-standard sizes, making off-the-shelf replacements difficult to find. We can help identify the correct size and provide a diffuser designed to fit your existing ceiling surround.
Replacing your diffuser is a simple, cost-effective way to restore the quality of light in your space without replacing the entire skylight.

FAQ'S
Frequently Asked Questions
About Skylight Diffusers
Yes. In many cases the diffuser panel can be replaced without removing the skylight itself. A replacement diffuser can restore the appearance and performance of your skylight.
Over time exposure to sunlight, heat and ageing materials can cause diffuser panels to become discoloured or brittle. Replacing the diffuser can improve both light quality and the appearance of the ceiling.
Diffusers are usually sized to fit the ceiling surround. Measuring the existing panel or contacting a skylight specialist can help ensure the correct replacement size is supplied.
Yes. Most diffuser panels can be cleaned using a soft cloth, warm water and a mild detergent. Avoid abrasive cleaners that may scratch the surface.
The best diffuser depends on the room and the lighting effect you want. Opal diffusers soften light, prismatic diffusers maximise brightness and Glocell diffusers allow airflow for ventilated skylight systems.
