ICEBOX® IGLOO DESIGN
How to build an igloo with the ICEBOX®
ICEBOX® igloo construction tool is used for igloo building by creating sequential
blocks in place. You set the clamps on the form then fill it while packing.
after you have filled it you unclamp it and slide it to the next position. A
pole with 8 adjustments, 1 for each layer is used to create the correct catenary
shape and to help support the snow so you don't have to. After
finishing 5 rows you remove the outside of the form as the wall is now leaning
in far enough so the snow can be packed from the outside. The snow only needs to
hold its form well enough to stay in place until you start the next block. 8
total rows are created including the final cap.
What's So Cool About The ICEBOX®?
it has less to do with temperature and more to do with structure and stability.
Indeed, the foremost advantage of constructing igloos with the ICEBOX® is its
stability. Incorporated into the design of the ICEBOX® as it is used for building
igloos is an intrinsic natural balance called the catenary curve structure.
This advantageous design will keep the ICEBOX® igloo from collapsing and will
prevent outward bulging of the igloo walls. The occupants inside will remain
safe and secure while the igloo building itself will stand rock solid for a good
long time, often enduring the length of an entire season. This is how to build
catenary curve structure of an ICEBOX® igloo for igloo construction is based on
a time-tested principle of natural balance and construction. ICEBOX® igloo
construction uses this very same principle. This very principle was used in the
planning and building of many of the European cathedrals. As cathedrals were
built higher and higher towards heaven, the outer walls of the cathedral could
no longer tolerate the stress placed on them from the weight of the cathedral
roof. No doubt scratching their chins in dismay, ancient engineers finally
figured out a remedy in the form of a supplemental wall brace they called
"flying buttresses." They built and placed these catenary curve-shaped stone supports as dueling pressure against the pressure pushing
down from the cathedral roof. This is how to build an igloo.
ICEBOX® uses the same principle when constructing igloos. Snow (and ice) flows.
Calculated properly, a catenary curve of snow will create a force of pressure
pushing in that is equalized by the amount of pressure pushing down. What
results is a natural and extremely stable balance. From the first tier to the
roof, an ICEBOX®-built igloo remains structurally sound and exceptionally sturdy.
The catenary curve structure is an integral feature of the ICEBOX®. Use the ICEBOX®
for building igloos and you simply can't go wrong. That's what's so cool
