Your Rating

Q. My existing Skylight Diffuser is broken.  How do I measure the diameter?

A. We suggest you can trace around the main pieces to form a circle, then fold the circle in half to find the diameter.

Q. What if I need a custom size diameter?

A. Select the next larger diameter size, eg. if you need 460mm, then select a 500mm dia Round.  When you go to the Checkout, there is a box available for your comments and you can specify that you require your Diffuser to be 460mm dia Round.

Q. Can you supply dome-shaped Skylight Diffusers?

A. No, we specialise in flat sheet Acrylic only, but we can do custom sizes to make it easy to fit your existing Skylight surround.

Q. How are your Skylight Diffusers shipped?

A. We package the Skylight Diffuser between 2 square pieces of heavy duty cardboard and seal the sides totally for protection.  We use either Australia Post shipping or Courier Shipping.

Q. Do you supply replacement Surrounds for the Skylight?

A. No, this is not our area of specialisation. We recommend you google “Skylight replacement surrounds” to locate someone in your local area.
