Product Description

Replace your existing Skylight Diffuser – its a great way to improve the look and feel of your home

Made from soft 3mm Opal Frost Acrylic Plastic Sheet, it is easy to install into your existing skylight surround.  Comes in round, square or rectangle shape. Square and rectangle sheet have a corner radius for easy handling.  We can do custom cut to size.

Your replacement Skylight Diffuser is made from flat opaque plastic, designed to go into your existing metal or plastic frame.  This is not suitable to replace domed shaped Skylight Diffusers, as they have a different clip system.

Custom Sizes available:  please contact us with your measurements.  Or you can choose one size larger than needed, but when you go to our Shopping Cart/Checkout let us know in your purchase comments the size that you would like to have cut.

Packaging:  We flat pack the Skylight Diffuser in heavy duty cardboard to protect it during transit.  The Skylight Diffuser will also have a protective film on both sides which you peel off prior to installation.  If you have trouble removing the film, try sticking some tape near the edge to lift the film and peel off.

Installation:  Simply remove your existing Skylight Diffuser by lifting the sheet upwards in one corner and gently manoeuvre it from the frame. Our Square and Rectangle sheets have a radius corner which makes fitting simple and easy. Always take care with your hands, as the sheet can have sharp edges.


For sizes 1000mm and over, please supply a location address and phone number in your comments. Australia Post shipping not available for sizes over 1000mm, flat rate courier shipping only.

    This skylight diffuser is great and it exceeded my expectations. It’s very thick, sleek and looks great in the ceiling. So much better than what we had before! We had a custom size made and it arrived quickly.

    Exceptional service and it worked exactly as it said for ordering a custom size. Could not have been easier or quicker (esp in these days of COVID). Many thanks.

      Thanks for your comments Tracy. We hold sheet stock of the Acrylic Sheet so we cut to size for each order. All you need to do is add your measurements into the Comments section in the Shopping Cart and we cut to size.
      Great that you found that system simple as we intended. Enjoy the new ambience that comes with the light from your Skylight.
      Thanks and regards
