The Megadoor is very energy efficient. A testament
to that is the fact that Alaska is one of our
best markets. Our origin is from Northern Scandinavia
and the North Sea coast, so we are very familiar
with cold weather requirements. The main reason
for the energy efficiency of the door is the
tightness. There is almost no draft coming through
the door. Studies have proven that approximately
80% of the heat loss on a large door comes from
air infiltration. So, a tight door is more important
than one with a lot of insulation.
The air infiltration follows this formula:
Leakage (CFM) per leaf = (Total Door Ht. In feet) X (2)
There is also
another important factor in hangar doors when
the Megadoor is compared with the sliding door.
Due to the vertical operation of the Megadoor,
it can be opened to any height to accommodate
a smaller airplane or other equipment. This
will save on heat loss inside the hangar by
not depleting the heated air and thus saving
on recovery time.
