We offer various types of poly coverings and accessories for your growing projects or our high tunnel greenhouses.  We can provide you with rolls of 20ft x 50ft clear poly covering for the small backyard Greenhouse to the larger Greenhouses up to 50ft x 200ft. We offer a superior quality (7 Layer Film Technology) greenhouse poly called THERMAX with proven performance by local Canadian growers. NOTE: We do not do custom cuts, and just sell pre-sized rolls as per below.

Super 4 Poly (6 Mil) blocks 100% UV but allows 91% of the light through

We also offer an opaque white/black poly film that can be used for either ground cover or as a reflective blackout curtain for photo period control. The white side is used for reflecting light back to your growing area (90% of all light), while the black side prevents light filtration from the outside.  We provide large custom 12 mm silver/black blackout covers to the size you specify. We also provide Channel Lock and Wiggle Wire to attach your poly to greenhouse frames.

Greenhouse 6 mil poly covering

NOTE: Plastic sheeting is measured in mils. A mil is a measurement that equals one-thousandth of an inch, or 0.001 inch. One mil also equals 0.0254 mm (millimeter).

Greenhouse Shade Cloth

You can choose from two different kinds of Greenhouse Poly: SUPER4 (6 mil with 4 Year Warranty) and THERMAX (anti-condensation poly). If you need a single layer of Greenhouse Poly, you will likely want to  use SUPER4. If you need a double layer poly, then you will use SUPER4 on the top and THERMAX on the bottom. Some growers will use a double layer is they don’t want any condensation falling on their seedlings and want a higher temperature.

Traditional vs Greenhouse Poly

SUPER4 – Durable and Tough

Dura-Film® Super4™ is a super clear, super tough, long-life product, guaranteed to provide you with the best value in a 6-mil, 4-year greenhouse film. Dura-Film® Super 4™ offers the best value with improved properties over older generations of greenhouse coverings. Superior strength and toughness. Higher light transmission. Guaranteed longer life – 4 years. Folds up to 210% stronger. Tear strength up to 164% higher. Puncture force up to 12% higher. Advanced UV up to 33% longer life.

Benefits:

  • Outstanding light transmission, haze, and clarity ratings help optimize greenhouse yield.
  • A unique manufacturing process results in a Greenhouse Poly with superior tear strength & high strength at folds means higher resistance to punctures.
  • Advanced UV protection.

THERMAX – Durable With Condensation Control

Thermax™Dura-Film  combines outstanding thermal qualities and exceptional condensation control in one revolutionary, diffused greenhouse film. Thermax is also guaranteed to withstand 4 years of UV exposure under normal circumstances. 

Benefits:

  • Outstanding thermal properties keep the heat in by reducing radiant heat loss. Heaters cycle less often and consume less energy to maintain a set temperature, a combination that offers potential energy savings of 15-20%.
  • Directional condensation control, controls drips & maintains light transmission & enhances thermal benefit.
  • Diffused light reaches plants from many different angles, optimizing light distribution in all parts of the greenhouse. Diffusion helps protect plants from sunburn. Light is even, not intense.
  • Increased film stiffness makes the film easier to install in greenhouse applications.
  • Research shows that a properly inflated double poly-covered greenhouse can save the grower over 40% in heating costs compared to a single layer of glazing. What is less well known is that using a thermal film as one of the layers can result in an additional 15-20% heating cost saving.

OPAQUE - Black and White Poly

Our Canadian-made Dura-Film® Panda™ 5 mil is a highly reflective, durable, and opaque white/black poly film that can be used for either ground cover or as a reflective blackout curtain for photoperiod control. The white side is used for reflecting light back to your growing area (90% of all light), while the black side prevents light filtration from the outside.

Benefits:

  • Brilliant white layer ensures maximum light reflectivity to aid in crop production.
  • Provides maximum control when used as a blackout curtain for your crops.
  • Reflects heat and cools better than shade cloth.
  • Designed specifically to withstand the wear and tear of either foot traffic or retractable curtain systems.
  • Used in construction and also as an agricultural weed barrier.

Channel Lock & Wiggle Wire

Channel lock and wiggle wire provides an easy way to attach poly to your greenhouse frame without cutting it.  You simple press a fold of poly or other material up to 20 mm thick into the C-channel, and insert the wire over top of it to secure it.  This is great for 2 layer insulated poly applications as well as for creating side vents for your greenhouse.

NOTE: To buy select "Channel Lock & Wiggle Wire" and "6 Foot Length" and Add to Cart.  Then in your cart, increase the quantity of 6 foot lengths you need.
