Terrace - side glazing - supplier mix possible?

Hello

we have a terrace roof of the brand Erhardt, model T150 as an overlay installation.

Now we would like to close one side.

The manufacturer itself also offers this, but personally, I find the price a bit too high. Are there quality-wise similar suppliers that can be combined with each other and are more affordable?

Our terrace slope is 2% over 5m, so about 10cm height difference from the house to the terrace end. We will probably have to adjust a bit (lower the walkway to the terrace and somehow install a step :(

The following things are roughly needed (existing offer with original parts)

To be able to name providers for you, the indication of your place of residence is missing. A provider far away from you is probably of little use, as they will be more expensive for travel.
