How many mils is the polyethylene cover?

Asked by: NHgirl
Hello, Since our fabric is triple layer woven, unfortunately, it cannot be measured in mils. A mil thickness is the measurement used for one layer fabric. Once multiple layers are being added on the one way to measure it is in oz. This cover is a 5.5oz cover fabric. If you have any additional questions or concerns please feel free to call us at 1-800-932-9344. Thank you

Features & Benefits

Big quality features. Value priced. Learn more about this product below.

  • Choose Your Own Size: We make building your very own custom High Tunnel Greenhouse easy. Choose from Greenhouse frames as small as 8 x 8 ft., or as large as 38 x 15 ft. and up to 100 ft. long! Select a size that meets your requirements and fits your needs.

  • A Stronger Greenhouse Structure: Unlike many of our competitors, we use only high quality galvanized USA manufactured carbon steel for ultimate strength and durability. Our steel is certified ASTM A653 for maximum resistance against corrosion and rust.

  • Long Lifespan: Our High Tunnel Greenhouse frame comes with a 3 year prorated warranty, so you know they have been built strong.

  • Secure Anchoring: All High Tunnel Greenhouse frames come equipped with 30 inch base pipes. Once anchored securely, these pipe anchors will prevent the greenhouse frame from racking or wobbling at connection points.

  • Stable Structure: Our patented ShelterLock® Stabilizers provide rock-solid strength and stability to the frame of your High Tunnel Greenhouse. ShelterLock Stabilizers are made of steel and act as tough, reliable connectors at every purlin, preventing racking and wobbling so your frame stays put.

  • Simplified Assembly: Pre-drilled holes in our galvanized steel piping make assembly of your High Tunnel Greenhouse Frame easier and more efficient. Nut and bolt fasteners not only simplify assembly, but add to the stability of the structure, reinforcing connections at every joint.

  • Step-By-Step Instructions: All of our buildings come with simple step-by-step instructions for easy assembly.
