Opaque plastic in Blender

Question

I have been trying to produce a polytunnel in Blender, without success. Can anyone please let me know how to make a tunnel covered in opaque plastic.

Welcome to Blender Stack exchange. As wikipedia says

A polytunnel (also known as a polyhouse, hoop greenhouse or hoophouse, grow tunnel or high tunnel) is a tunnel typically made from steel and covered in polythene, usually semi-circular, square or elongated in shape.

I tried making a low-poly tunnel with least efforts quickly, it looks like this :

The way I achieved this is by

1. Modelling the polytunnel in the way I wanted.
2. Adding a transparent shader/glass shader as the material to make that plastic covering.

Here's the node setup for the material:

You can also use the glass shader, here's the usage: I can't make my material transparent in Blender 2.80
