If you’re ordering a limestone fireplace surround or marble fireplace surround, you might notice an option for closures. These are used when you want to fit your surround against a flat wall without a rebate. Here’s what they are and how they work

Our Aegean limestone surrounds and marble surrounds are supplied with a standard 75mm (3-inch) rebate. This is a recessed area at the back of the surround, mainly designed to accommodate traditional cast iron fireplace inserts. Closures are three separate pieces of matching limestone or marble, made up of two side pieces and one top piece. These fill the existing 75mm rebate, giving you a surround with no rebate.
The three closure pieces are supplied separately and glued into the rebate at the back of the fireplace surround before installation. We use Marble Glue to attach the closures. This is a two-part adhesive suitable for limestone and marble, with a separate hardener that is mixed with the glue before use. It’s important to fit the closures beforehand, as there may not be enough room to fit them once the surround is against the wall.
Once glued in place, the closures aren’t designed to be removed. Trying to remove them later could damage the limestone or marble, so it’s worth deciding how you plan to use your fireplace before ordering.
For some of our more popular limestone and marble surrounds, we have separate versions manufactured with no rebate at all. For other designs, we supply the standard 75mm rebated surround with matching closures instead. This means we don’t need to stock two versions of every surround.
Both options give you the same finished result.
Closures require additional limestone or marble, which is why there’s an extra charge. Our purpose-made no-rebate surrounds also cost more than the standard rebated versions because they require additional material and manufacturing work.
Both options cost around the same. The difference is simply how the surround is supplied.
| Option | What you receive | Best suited for |
|---|---|---|
| 75mm rebate | A surround manufactured with a 75mm rebate | Traditional cast iron inserts |
| No rebate (0mm) | A surround manufactured without a rebate | Fitting directly against a flat wall |
| Closures | Three separate matching limestone or marble pieces that you need to glue into the rebate before installation | Converting a 75mm rebated surround for flat-wall fitting |
If you’re planning to use a gas, electric or bioethanol fire, the rebate you need depends on the fire you’re using and how it will be fitted, so it’s worth checking before ordering.
