How to build an igloo with the ICEBOX®
The 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®?
Actually, 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 an igloo.

The 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.

The 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 about the ICEBOX®
