By doubling the layers of Greenhouse film and adding an inflation fan to expand the layers 3 – 5 inches apart will save you approx. 45 to 50% on heat loss. Use infrared film and you can save another 15 to 20% on heat loss especially on Clear cold nights. If you have questions feel free to ask. I use to be a Greenhouse construction and managment consultant.
