What is this tile?

shinytop

It's a two part sandwich arrangement.  The bottom one has ridges underneath, top one is smooth.  165mm wide.  Any ideas? I've broken a couple and need replacements. 

Thanks

Normally creasing tiles are used for a tiled cill, but sometimes as in your case roof tiles are used. The bottom ones are reversed and have the nibs showing. You have to crop the ends to make them fit.
Which are broken, top of bottom?
Take a broken piece to the merch for a good match.

They are similar to roof tiles but without the nibs and are not cambered. They are usually a lot harder than roof tiles.
People often use roof tiles to save cash.

Brilliant, thanks.  Top and bottom broken unfortunately.

To build them I fix a piece of batten to the wall to take the bottom tile, otherwise they tend to sink.
