PE vs PVC fabric and why we choose PVC for our PVC 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 fabric building cover.

Also referred to as:

Our fabric buildings are often called high tunnel or coverall. They get their name “High Tunnel” because they resemble a large tunnel for storing larger objects such as vehicles, airplanes, boats, tractors, and RV’s.

They get their name “Coverall” because they do just that. They cover all of your belongings to protect them from weather as well as allowing you to feel a sense of security knowing your projects, tools and equipment are well protected and hidden.

As a barn alternative, these fabric buildings are also called hoop barns, due to their galvanized steel “hoop” arch frames, and provide an economical option and quick build for storage needs, compared to traditional pole barns.


Common Uses:

Our fabric buildings, also referred to as hoop barns, have a variety of uses such as: vehicle garage, equipment & machining storage, sports & recreation, aviation, environmental, government, hospitality & conventions, manufacturing, job site warehouse, mineral storage, mining, oil & gas, part, industrial & warehouse storage, agriculture and equipment storage, hay storage, landscaping storage, rv and boat storage, animal shelters, worksite shelter, and an endless number of other storage and shelter uses.
