Have built a foundation for a greenhouse using standard blocks 190x190x590 mm type leca. Will plaster the outside of the wall this weekend. Would like to have a cover plate on top to avoid future problems with frost damage etc., before installing the greenhouse frame on top.

Have searched both here on the forum and everywhere else, but some things seem un-googleable... what are some reasonably priced standard solutions? Links appreciated, as mentioned, it's damn hard to find if you don't know the exact search term/product. I think this should be a standard product, but what do I know.
 
Depending on which brand you use regarding greenhouses, they probably have a solution. Alternatively, consult with a sheet metal worker to have them fix flashing for mounting in the frame of the greenhouse. Letting the frame rest on metal is something I don't believe adds anything since attaching the frame would perforate the metal, leading to a risk of leakage and frost damage as a result.
Kind regards, Masen

It's a budget greenhouse from China, so it's unlikely there are any ready-made solutions. But it was a good idea to attach the sheet metal to the greenhouse frame instead; as you say, it becomes somewhat pointless if water runs down through the fastening holes if you attach the frame over the plate as I initially thought.

I'll consult with a tinsmith later when the frame is in place and I know the exact measurements; significantly better chances to get it reasonably tight on the outside so rain can run off the parapet and the exterior via the drip edge as usual. Thanks for the response!

You can check through the standard plates for windows, doors, tsk etc and see if anything fits the purpose.
