Winter Air Inflated Double Layer GreenhouseAir Inflated double lined what?   No, we don’t mean it’s a blow up, no need to get light headed already.

Just giving you the 411 on a great installation method for best usage of your greenhouses!! Let’s get to it!


Air -inflated double polyethylene film layers for greenhouses represent around 80% of new greenhouse construction in the United States. There is a multitude of reasons for this.

  •  The plastic is porous,  meaning both carbon dioxide and oxygen is able to come and go,  allowing plants to survive within a tightly sealed structure such as a greenhouse.  A surviving plant is a happy plant!
  • The use of an air-inflated double layer system allows the grower to have an increased temp up to a 40 degree difference from outside, with no additional heating  expenses.   Big Savings, who doesn’t want that?!!
  • The double layer system makes the greenhouse structure more weather resistant to harsh winter conditions, which means longer growing/harvesting times and very happy growers!

For an air-inflated, duel layer poly greenhouse you must allow 4-8 inches in between two specially designed layers of poly film.   Stuck on what kind of greenhouse plastic to use??  Here’s what is highly recommended:

The Outside Layer –

Should be a highly diffused (milky looking) film treated with UV inhibitors.  Our Luminance poly film for greenhouses diffuses the sun so light reaches the plants from all different angles. This also keeps plants from being scorched by any uneven concentrations of sun light.  Let’s keep the sunburns outside!

The Inner Layer –

Condensation control is what you are looking for in this layer.  Thermax poly film for greenhouses offers a unique directional condensation control which ensures condensation is spread out evenly into a uniform sheet on the interior surface of the film. The thin sheet of water is absorbed in the long-wavelength IR regions meaning it acts an additional barrier to radiant heat, ie. enhances thermicity.  Non-drip control films allow droplets to form and drop onto plants often causing disease within greenhouse plants.  With Thermax, this is eliminated.


Once you have your double layer greenhouse film in place,  what’s the next step?  Install and run double layer inflation fans of course!  One recycling inflow and one recycling outflow to keep everything all nice and happy!
