All replacement skylight domes and replacement skylight diffusers and covers are manufactured using the highest grade high impact acrylic sheeting, for superior clarity of light, resistance to discolouration, impacts and longevity.
Measuring for a Replacement Skylight Dome
The correct replacement skylight dome size is determined by the throat measurement of the skylight flashing — this is the roof opening that must be fully covered by the new dome.
Follow these steps:
Remove the existing dome
Detach the dome from the flashing/base.
Domes are usually fixed with screws or pop rivets.
Measure the dome itself
For round domes, run a tape measure across the widest point (edge to edge).
For square or rectangular domes, measure straight across from edge to edge.
This gives you the dome’s edge-to-edge size (e.g., 420mm).
Measure the skylight throat (roof opening)
Run a tape across the skylight opening, also known as the throat or nominal size (e.g., 400mm).
This measurement determines the skylight model, shaft size, ceiling insert size, and diffuser size.
It is especially helpful if you are replacing other components or cannot confirm the dome’s edge-to-edge size.
Note: All replacement skylight domes listed on our website are specified by edge-to-edge measurements.
Measuring and Selecting a Replacement Skylight Diffuser
Identify the diffuser type
Determine whether your existing diffuser is a flat model, domed model, or vented model.Measure the diffuser size
Measure across the diameter of the diffuser to confirm the required size.
If the diffuser is cracked or damaged, you can alternatively measure the ceiling insert opening to estimate the correct size.
Check the diffuser material
Consider the material and finish of your current diffuser. Is it frosted acrylic or a prismatic style? Matching the material helps maintain consistent appearance and light diffusion.Confirm the fixing method
Determine how the diffuser attaches to the ceiling insert:Does it twist and lock into place?
Or does it simply sit on the inner lip of the insert?
When an exact replacement is unavailable
Some skylight companies may no longer be trading, or certain diffuser styles may have been discontinued. In these cases, a compatible diffuser may be suitable, or it may be necessary to upgrade both the ceiling insert and diffuser to a current model.
