How to measure for replacement skylight domes properly
The replacement skylight dome size that you require all depends on the size of the skylight flashings throat measurement. This is the skylights roof opening that you want to make sure is covered by the new skylight cover. Steps are as follows;
Remove the dome from the flashing/ skylight base. Most of the time domes are screwed on or pop riveted.
Run a tape edge to edge across the diameter of the dome if it is round, or measure edge to edge of the skylight dome if it is square or rectangle. This measurement will give you the dome size (e.g 420mm).
Now run a tape across the skylight opening, otherwise known as the throat size or nominal size (e.g 400mm). This measurement will tell you the size/model of your skylight. It also tells you the shaft size, the bottom ceiling insert size and the diffuser size. This measurement is useful when replacing other parts. It is also useful if you are having trouble sourcing the edge to edge dome measurement.
*All of the replacement skylight domes listed on our website are edge to edge measurements.
How to know which replacement skylight diffusers you require
First you need to decide if the diffuser replacement is a flat model, a domed model or a vented diffuser model.
Then you will want to measure across the diameter of the diffuser so you know which size you require. If your skylight diffuser is cracked you can measure the opening of the ceiling insert and get an estimate from that which size it may be.
What material if your replacement skylight diffuser made from? Was it a frosted acrylic or a prismatic style.
Finally does your diffuser attach by twisting and turning or placing onto the lip of the ceiling insert.
In some cases you will not find your exact replacement as the skylight company has ceased trading or the style is discontinued. In which case another skylight diffuser may suit or an upgrade of the skylight ceiling insert and skylight diffuser may be required.
