Composite door change

[dazzab]

I've been searching online for ages and cannot for the life of me find an answer to this dilemma.
I currently have a composite door fitted to my home but has no glass in it and so make's my porch dark and dreary.
I do not want to fork out the large amount of monies for the full composite door with frame and am searching if I can just replace the door with another composite whilst the original frame remains in situ.
Any help would be appreciated. It is not a bespoke made to measure door...just standard.

Do you know the make of the door? It may be stamped on the side of the door somewhere.
If so yes it should be fairly easy to get a new slab.

A cheaper option (but maybe tricky to find someone willing to do it) would be to buy a glazing cassette and glass for your style/make of door and cut the holes in it (this is what they would normally do in the factory when making them).

most composite door suppliers should be willing to sell you a slab only.
