I have a query that you might help me with please.
My son is currently building a polycarbonate greenhouse for me. He has built the frame and has put in some windows.
We are worried that we might not select the correct polycarbonate for the greenhouse. Is 4mm, twin wall good in Ireland or should we go for 10mm twin hall?
Any advice would be REALLY APPRECIATED. There are varying views on the internet!
With many thanks to you for your time, it is appreciated.
Mary
