Igloo Building Details
Material's have been tested to -70 deg F. One ICEBOX® tool will build a 7,8,9,10, or 11 ft Igloo.
ICEBOX® configuration inside dimensions and weights:
7 ft. by 44 inches tall: 4.8 lbs (2.13 X 1.12 meters tall: 2.18kg)
8 and 10 ft by 61 inches tall: 4.88 lbs (2.44 and 3.05 X 1.55 meters tall: 2.22kg)
9 and 11 ft by 67 inches tall: 4.92 lbs (2.74 and 3.35 X 1.7 meters tall: 2.23kg)
Comfortable sleeping capacities for people 5'8" (1.54m) without a trench are:
7 ft. (2.13m) = 1 person, or 2 people less than 5 ft tall.
8 ft. (2.44m) = 3 people
9 ft. (2.74m) = 4 people
10ft. (3.05m) = 5 people
11ft. (3.35m) = 6 people
Digging a hole or trough will allow you to sit with legs hanging instead of cross-legged style. You can build with any snow conditions (including sugar snow, slurpee type ice, depth hoar) allowing you to stay in the woods and out of the wind.
Takes less than 50% of the effort required to build a quinzhee or dig a snow cave of equivalent size. Build time is approx. 1-1/2 to 3 hours depending on snow quality and quantity. Shorter build times mean you will not be fatigued when complete and you will stay cool enough to prevent sweating and snow from melting on the outside of builder's jacket.
Straps onto pack easily using supplied straps and buckles. Straps have auto release snaps allowing builder to keep gloves or mittens on. Slip form has auto release snaps to prevent form from breaking if it happens to fall full of snow. Snaps also help in assembly of form allowing builder to keep gloves on. Parts are made of bright colors to prevent loss of smaller pieces in snow. Support pole helps create the exact same ICEBOX® Igloo every time. (no guesswork)
An ICEBOX® igloo snow shelter is so strong, 3 people have stood on top of a completed igloo (not recommended).
ICEBOX® igloo shelters are built by handling snow only once. (blocks are built in place) Builder is able to kneel or stand rather than lying down or kneeling like a snow caver. (Kneeling is only required for the first row.) You can extend the season since you only need 6 inches of snow to build and an igloo can be built from surface snow on summer glaciers. ICEBOX® igloos have been built on lakes with only 3 inches. (See North Dakota Minnesota photos.) Tall enough to facilitate standing up to stretch or get dressed.
Quiet, peaceful camping. No flapping in the wind like a tent. Just plain fun.
With outside temps of -15 F and two candles burning the temps will be 48 F at the ceiling 38 F at the floor. With no heat source and all occupants in sleeping bags the temps 38 F at the ceiling and 34 F at the floor. No need to sleep with the water bottle.
