You can save a considerable amount of energy in the greenhouse
with a few simple steps. 1) Insulate the greenhouse foundation
(See Foundation FAQ). 2) Insulate the north wall and north roof.
Little light comes through the north wall of a greenhouse in the
northern hemisphere, so insulation of this wall helps with
energy losses without sacrificing any sunlight. One approach is
to install foil-backed foamboard insulation, with the foil side
facing into the greenhouse. 3) Seal off vents, weatherstrip
doors, and caulk or otherwise close off other areas of air
infiltration. 4) Double up on glazing. A double or triple layer
of glazing can be added with an additional layer of polyethylene
or with the addition of "bubble wrap." 5) Add thermal mass to
the greenhouse (See FAQ on thermal mass). Information provided
