Roofing felt on plastered wall?

[BiFuel]

Should I lay a syllpapp on the plastered wall of the greenhouse to reduce the risk of frost damage? The edges of the greenhouse will not cover all the way out, plus the corners are not covered (see pictures).
Is there any disadvantage to laying down a syllpapp?

Yes, it is preferable. In our assembly description (Williab garden) it was indicated, for example.

Great, I'll go with that. Vitavia's instructions left a lot to be desired
