Colorado Yurt Snow and Wind Packages
Different climates demand different engineering requirements. High elevation, high snowfall or high wind areas call for a different approach than tropical climates where high rainfall and hot temperatures determine the design elements of a yurt. In some cases a simple yurt structure with no engineering elements may be appropriate. Our experienced staff can help you decide which options are necessary in your situation.
- CORR Brackets (Compression Ring to Rafter Brackets) - strengthen the connection between the rafters and the compression ring and reduce the potential for rafter-twist. CORR Brackets are an exclusive Colorado Yurt option.
- Deep Powder Package - upgrade to 2"x6" rafters (from the standard 2"x4") to increase snow loading. Includes CORR Brackets.
- Big Wind Package - a 2"x4" perimeter stud under each standard 2"x4'" yurt rafter. Yurts with this option are rated to 90 mph, exposure C. Exposure C includes flat open areas such as grasslands, coastal areas and above tree line which have virtually no wind breaks. The package includes CORR Brackets, an exclusive Colorado Yurt option.
- Full Snow and Wind Package - combines 2"x6" rafters and 2"x4" perimeter studs for the highest level of load capability. Includes CORR Brackets.
- Winter Stout Alpine Yurt Package - includes 2"x6" rafters, 2"x4" perimeter studs, CORR Brackets, an Alloy Compression Ring, a Center Support System and two levels of Rafter Blocking.
Snow Load Ratings
If snow load is a serious consideration in your area, we have several levels of upgrades to choose from. The snow load data below is for our CORR Bracket Upgrade, Deep Powder Package or Full Snow and Wind Upgrade. These are suitable for most situations. Ski Resorts and other yurts at high elevation, especially if there will be times when the yurt is unheated, should consider the Winter Stout Alpine Yurt which can handle as much as 169 pounds per square foot (psf) of unbalanced snow load on a 30' yurt. To find out what the requirements for snow load are in your area try entering your zip code at http://groundsnowbyzip.com/. If data for your area is not available on this site, try doing an internet search that includes the search words "your county your state building codes snow load". Here is a sample of what you find when you do this for Montrose County Colorado, the county in which we reside. See page 2 of the Montrose County Building Handout.

*Engineering data is for reference only. Based on the assumption that the snow is loaded evenly across the roof. Combined and eccentric loads are not considered in this chart, but are taken into account on our Winter Stout Alpine Yurt data. Structural analysis is in accordance with the 1997 Edition of the Uniform Building Code and the 2003 International Building Code. Please call 800.288.3190 for more information. |
