Jigsaw time! Arrange the pieces as best you can into shape, then trace or measure your diffuser.
For circles, trace onto paper, then fold the circle in half to find the diameter.

The Skylight Diffusers are custom cut from 3mm thickness Acrylic Plastic Sheet.  The “colour” is Opal Frost which provides a soft glow.

Select a larger size, e.g. 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.

Provided you are fitting your Skylight Diffuser replacement into a solid frame, it is generally strong enough to hold up without sagging.

We specialise in FLAT sheet Acrylic only, but we can do custom sizes to make it easy to fit your existing Skylight surround.  We recommend you google “Dome Skylight Diffusers” to locate a supplier in your local area.

This type of plastic is called “prismatic”, and is mainly used for commercial purposes.  We use a flat plastic Acrylic sheet which provides a softer glow and a lifts the appearance of your home to a more modern look.

We do not supply the prismatic sheet, so if you need to match your Skylight Diffuser replacement to match other existing prismatic diffusers, you will need to google search “prismatic acrylic” to find a supplier in your area.

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.

This is not our area of specialisation. We recommend you google “Skylight replacement surrounds” to locate someone in your local area.

There will be a plastic film on both sides of the skylight that can make it looked scratched. Have you peeled these of yet? Sometimes the film can be hard to notice!! If you have trouble removing the file, try sticking some tape near the edge to lift the film and peel off.

Turning is a common method for machining plastics. In this process, a plastic piece is held in place on a lathe and rotated against a cutting tool.

Large-toothed saws or blades should be avoided as they will cause the plastic to break or crack and leave uneven edges. You will need a saw with a fine-toothed blade in order to cut plastic. Make sure your plastic is fixed to a level surface or work surface before using a hacksaw, jigsaw, or fine-toothed saw to cut it.

Plastic can be bent in two ways – around a shallow curve or along a sharp corner. When bending a sheet around a sharp corner you will require heat to get the desired radius. With heat bending, you tend to heat the plastic to a specific line or point in the sheet and hold it to the shape.
