Experiments in Prototyping a 6' Hexayurt Shelter from Kingspan Metal Sided Sandwich Panels to Bear a Snow Load for Winter Storage use


Building a Prototype for a 6' Hexayurt from Kingspan Metal Sided Sandwich Panels for Winter Storage  use to Bear a Snow Load

Please Note: at this stage we are experimenting with loose ideas from off cuts of older metal sided Kingspan brand rigid foam sheets & reused drywall framing




From looking at instructions & info at Hexayurt.com and Hexayurt playa
We decided to have a go at this.  There are over 30 Hexayurt designs. we started with the smallest for practicality

Given a potential virus caused economic depression & further crisis with a lack of low cost / easy build shelter for temp housing / work space / storage  perhaps Hexayurt designs will become more popular



We first cut and propped the 1m x 1m + size kspan sheets (80mm thick wall & 45mm thick roof ) and propped them up to explore ideas

The First idea was to have an enclosed gutter & raised edge (this was already on the offcut panels edge) The thought being that this would hold snow on the roof in winter as extra insualtion . However a very good seam seal would be required to stop leaks to inside

Top edge was cut off to make it flat against the foam end and drwall frame I beam laid on top .
Folded edge on one side, useful for fitting to wall. perhaps with drywall frame I stud as shown in pic (146mm wide )

146mm wide I stud on top of wall is too wode , but if wall was cut at an angle to mount roof, it would fit more tightly



lay up of 2 longer wall drywall studs (92mm wide) scrwed back to back to form dee pwall I beam for joining roof sheets

Cttting & fastening wall panels together

Peel steel on inside away from foam by hand & cut by hand with sharp kitchen knife

Note: a thin strip of folded metal had to be cut off the edge

Note: After cutting & bending, it was a great fit,
utilizing the exisiting overlapping flap

Screwed im place with 3 rows of self drilling flange head screws inside & out

A 92mm  drywall frame stud beam was cut & bent ove the wall ridge to cover the top awaying connection of the roof panels
