The Alaskan Nomad Shelter yurt is a design based on the traditional ger or yurt design of the central Asian steppe nomadic herding people. The design includes a circular lattice frame and rafters supported by compression into a central ring at the top. This design is ages old and very well proven.
The central Asian people have used yurts or Ger for thousands of years as primary residences in the harsh windy steppe environment. The Ger offers wind resistance and good snow load strength while providing a light , warm , circular interior.
How Is This Design Distinctive?
The Alaskan Nomad Shelter yurt has many features that will only be found in the Alaskan yurt. Beyond the quality of construction, the following distinctions make the Nomad Shelter the best value for extreme weather:
Cover- The cover is made of Duro-last roofing membrane 28 oz polyvinyl. Nomad Shelter uses this fabric over the entire yurt for the standard cost because it will not mildew, degrade with UV or sustain a flame. This fabric is the only fabric that comes on the standard yurt.
The cover is designed with facings that cover the joins in areas that could be susceptible to drafts. There are facings covering the join of the top to the wall, facings over the door join and around the windows to stop the drafts coming up between the insulation and the cover.
The cover also has a sewn rain divert er over the door that sheds the rain away from the threshold. These features are standard in a Nomad Shelter yurt.
Lattice - The wall lattice on a Nomad Shelter yurt is made of 1"x2" white spruce riveted with 1/4 inch rivets .
The top of the wall is fastened with bolts for strength in bearing the weight of the rafters.
The Nomad Shelter lattice is structurally engineered with this added dimensional strength to support the rafters and provide 60 lbs per square foot snow loads and 100 mph wind resistance without vertical supporting posts.
Rafters - Nomad Shelter rafters have wooden connections to the central compression ring. The way the joinery is designed to insert directly into the compression ring gives the connection extra strength.
There are no pin connections so there is no torsion or twist in the frame. The rafters do not need holes drilled wire lacing to prevent twist. There is one hole drilled in the rafter toward the top for a gust lock cable . That is the only place the dimensional strength is compromised in the length of the rafter. Rafters are all finished and oiled to bring out the natural grain of the wood.
Rings - Nomad Shelter Central compression rings are layers thicker and a foot wider on each size then others you will find.
The 4 foot rings on the 12', 14' and 16' dia. yurts have 3 layers of glued and bolted douglas fir 2x material. The 5 foot rings used in the 20' dia yurts have 4 layers of the same. The 6' diameter rings used on the 24' and 30' have 2 layers of 3" glue-lams and one layer of 2x material so they are 7.5 inches thick. The 40'dia central rings have 3 layers of 3" glue-lam making them 9" thick.
Insulation - Nomad Shelter offers a 3 season liner that is similar to what is offered other places as a winter liner. It includes reflectix double foil backed bubble wrap. This is lined with a polyester mildew and fire resistant fabric. In addition Nomad Shelter offers a heavy winter liner that includes the light liner backed with 2" of polyester batting on the top cover and 1" on the wall. This is in turn backed with Tyvek building wrap creating a durable liner that can be repeatedly moved without wear or breakage.
There are many people in Alaska living with the Nomad Shelter liner as insulation for their primary residences. The owners Lee and Jess Tenhoff also use the heavy liner to insulate their residence yurts in Homer Alaska.
Skylights - Nomad Shelter offers an octagonal cedar and Plexiglas skylight that is distinctive. The design includes a safety bracket that supports a 6" MetalBestos stove stack through the center. The stack is safest when it exits the peak of the shelter for optimum draft. The stack is supported in high winds by the cedar frame providing the safest possible stack solution for extreme climates. The stack can be angled on the interior of the yurt to place the stove anywhere in the yurt that is desired. The skylight can be capped if there is no stove stack needed. Nomad Shelter also will provide the Tam light thermopane double dome skylight as an optional extra.
