PE vs PVC fabric and why we choose PVC for our Tension Fabric Buildings:

Both (PE) polyethylene and PVC are waterproof, but PVC is more so. Additionally, PVC is much more fire-resistant than polyethylene because the chlorine atoms it releases during a fire inhibit the process of combustion.

Poly vinyl (PVC) is made from the polymerizing of vinyl chloride monomer. Additional stabilizers and plasticizers are added to increase its light and heat resistant properties and increase its elasticity. These properties make PVC suitable for various industrial applications. PVC fabric is durable and designed to last a long time. PVC fabric is thicker than PE fabric, weighing between 20-28 ounces psf. Compared to PE, PVC fabric has a higher tear strength, making it a popular choice for fabric buildings that are exposed to high UV rays, strong winds and other extreme conditions.

PE fabric is a lighter type of architectural fabric, commonly weighing 12 to 15 ounces psf, with a shorter lifespan than PVC. PE fabric does self-clean very well when it rains and it is about 5% more light translucent than PVC.

Solid White Cover and Why It’s Important:

The solid white cover is very important because the dyed ends (usually green) that you see on some tension fabric buildings is a weak point in the cover. The dyed ends do not have the same ability to withstand UV rays as the undyed white fabric. We have received report after report from previous owners of hail penetrating the colored ends, but not the main white part, reports of the cover tearing at the seam where it transitions to the dyed end, and we have personally noticed excessive fading which can lead to premature failure of the cover.
