To make your greenhouse more of a year round functioning entity, there are two main areas in which you have to make the structure more efficient-Heating and Ventilation.
1. Heating is your biggest expense for the winter so retaining heat is a priority.
The easiest way to retain heat in your greenhouse is ….READ MORE
2. Ventilation is also one of your biggest considerations for the warmer times of the year. Ventilation can be done through forced or mechanical methods or passive through vents or roll up sides. ….READ MORE
Another variation on greenhouse plastic is with an IR (infra-red) coating.
The IR plastic can reduce your heat loss by up to 20% over a regular double poly installation.
Even though this plastic has a hazy look to it, the light transmission properties are actually a couple percentage points better.
This plastic comes standard with an anti-condensate coating which means there will be less dripping in the greenhouse.
All of these features make IR plastic an attractive alternative for many people in spite of the fact that the cost is roughly 20% more then regular plastic. This plastic does not have an inside or outside.
The cell structure that the Infrared plastic is made from is significantly different from the regular plastic. This gives the plastic a much softer texture and feel and contributes to it not being as strong as regular plastic. This is why we suggest that it only be used as the inside layer of a double plastic installation.
The slight restriction for people with shorter greenhouses is that the IR plastic only comes in 100′ and 150′ rolls. You would either have a friend who can buy/use the extra or be prepared to “waste” some. There are also not quite as many choices for available widths as with regular plastic.
Please call Norm to specifically inquire about more information regarding these special coatings.
