The Roof System
The rafters are select structural grade Douglas fir lumber, with larger/deeper rafters available if you need more insulation or roof snow load capacity.
The central compression ring is laminated of multiple layers of Douglas fir lumber doweled, glued together with waterproof glue. The ring is sealed with a coat of linseed oil. Rafters are pinned and bolted to the compression ring and bolt to the top plates of the walls. The rafter cable(s) hold the rafters in firmly to the compression ring.
The eaves, made of Inland Red Cedar are screwed to the rafters, and bird blocking (Douglas Fir) are nailed between the rafters. The metal roof is 24 gauge galvanized steel and is secured to the roof structure with roofing screws and bolts. The crown of the roof is finished with the skylight that is an operable thermal cast acrylic unit, mounted in an anodized aluminum frame.
The walls are framed with 2x6 lumber. The framed walls are sheathed with a 1/2" plywood shear panel, then covered with a vapor barrier and sided with 1x6 tongue and groove western red cedar siding.
During the yurt set up process the walls are screwed to each other and secured to the floor. A cable then wraps the tops of the walls securing them together into an integral unit.
Code Design Requirements
All construction is done to meet the specific wind, snow and seismic loads of the site where you will build.
Our yurt kits have been designed and engineered to meet up to 100 m.p.h. with 3 second gusts wind rating, category "C"; 100 p.s.f. snow load and class D-1 seismic ratings.
Any requirements greater than the above design ratings will require additional engineering. We can design to meet most wind, snow and seismic conditions. We offer site specific engineer stamped plans and building design/drafting to help you with your permitting process. All our work is done with care and attention to accuracy and detail!
