Insulation Comments
INSULATION: Greenhouse A three-layer job in New England; a glass-aluminum structure, with 5 mil Filon fiberglas mounted outside the glass and with aircap packaging material on the inside; refer to A78-100Inside lining with polyethylene is successful and convenient; use clear, with a thickness up to 6 mil. A77-995Space between layers = the space between the outer and inner liner should be about 1/2 inch, or the internal convection of air will greatly reduce the insulation value. A70-977Surface-mounted air-inflated plastic is suggested as an alternative method to reduce high fuel costs. A77-712The best is two layers of polyethylene to restrict heat loss by up to 40%; the two layers must remain separated by about three inches of dead air; the greatest efficiency is fiberglass panels with an inner layer of polyethylene film with no holes or tears. OD75-122 0
INSULATION: Greenhouses A double layer of film like a flat balloon which can be inflated a few inches and which covers the whole greenhouse provides an excellent insulation layer. A85-1119More than two layers of materials is not worth the investment in money because it reduces the amount of light reaching the plants; triple glazing is not recommended because of the cost, and the extreme weight. 0481-152With Styrofoam, use 2-inch batts on north side walls from below the floor line to the top, finish with foil.
