The 2 layers are applied using a tube lock base and a spring lock top. Many people in the business call them z strips. A blower is placed inside inflating the two layers. The lock base is applied to the frame of the GH and the plastic is stretched and the spring is used to hold it in place. Here's one site that shows most of the things you'll need. http://www.greenhousemegastore...
