Does anyone know the name of a barrier material to use & where I can buy it?

[Guest]

Got my new Riga IV greenhouse put up over the last couple of days. I do have the aluminum frame on treated 4x4’s. I read something the other day that the treated lumber can pit the aluminum & that you should put a barrier between them.

Does anyone know the name of a barrier material to use & where I can buy it?

We have Menard’s, Home Depot & Lowe’s in our area.

Roofing felt paper. Sold at Lowe’s and Home Depot.

Will you use this greenhouse all winter long? I’m in Missouri and I wonder if that’s even feesable in the harsh winter.

Gorilla tape would work.

I used a Trex composite decking board between my lower frame and treated wood.

Just ordered the Riga 5 and it will be delivered this Wednesday. So excited!! Going to pour a concrete perimeter wall for ours.
