The compression ring on the Winter Stout Yurt is metal instead of wood
A sturdy metal center post is part of the Winter Stout Alpine Yurt package
Turn buckles allow you to get a very tight connection between the compression ring and center support pole
Stainless steel hardware for strength and great looks
The center post and ring are reinforced by cables attaching the two
Blocking between rafters prevents twisting of the yurt when snow load is unbalanced
The Winter Stout Alpine Yurt is made strong by a metal compression ring, center post, 2 levels of rafter blocking and studs under each rafter
Winter Stout Alpine Yurt For Real-Life Snow Loads
Until now, yurt manufacturers have restricted their engineering data with footnotes indicating that only balanced snow loads have been considered. But rugged alpine conditions--a winter's worth of deep powder and big winds mixed with constant freeze/thaw cycles--almost always result in unbalanced snow loads. That's why we engineered the strongest yurt ever.
In real-life, unbalanced snow load conditions create torsion and tension which significantly impacts the structural capability of a yurt. Wind and drifts typically pile all the snow on a north quadrant of your roof while the sun melts the south side clear. The Winter Stout Alpine Yurt is engineered with three-dimensional analysis which shows the Winter Stout Alpine Yurt can support bigger snow loads than most stick-built homes. The engineering confirms that a single quadrant of your yurt roof--the north side or the leeward side--can handle four times the ground snow load stated in the chart below.

What does this mean for you? You can depend on the Winter Stout Alpine Yurt in serious snow load conditions at high elevations for residential and public use. It also means that you can document the structural engineering for building officials as you would for any building--without footnotes or exceptions. Engineering analysis is available.

Chart Definitions
- Fully Exposed - roofs exposed on all sides with no shelter afforded by terrain, higher structures or evergreen trees
- Sheltered - roofs located among evergreen trees or other obstructions within a distance of ten times the height of the obstruction above the roof level from the structure
- Terrain Category B - urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of a single family dwelling or larger
- Terrain Category C - flat open country, grasslands above timberline and all water surfaces in hurricane prone regions and any other open terrain with scattered obstructions having a height generally less than 30 feet
- Thermal Roof Factor 1.0 - structures that are kept well above freezing with roofs having an R value of less than25
- Thermal Roof Factor 1.2 - unheated structures
- PSF - Pounds per square foot
- Ground Snow Load - The load from snow that has accumulated on the ground. This is the standard used by IBC for permitting. Roof or live load, which is how most yurt manufacturers state their maximum snow load, is generally only 70% of ground snow load.
