PVC tunnel roofing membrane introduction:
PVC tunnel roofing membrane is a single-ply membrane that consist of two plies or layers of PVC material with a polyester reinforcement scrim between the layers. Top ply has special additives to make the membrane UV stable and prevent curing, and plasticizers to make it flexible, and pigments for color. IB also uses a layer of acrylic coating to make their roof more reflective, and to help repel dirt and dust. Bottom ply is a black PVC with plasticizers for flexibility and usually no other additives or fillers.
During the installation, PVC roofing membrane sheets are connected together by using hot-air welding (fusion welding) of seams, which creates a permanent physical bond between two separate sheets of roofing membrane. This hot-air welding process is what makes PVC roofing such a great roofing product – it can remain water-tight and pliable for decades after the originally installation.
