'Metalclad' Wall & Roof Frame in Place in Wedge Block Shelter

First Upright erected (rain stopped play) I cut out the notch from the bottom, but thought there may be a way of wrapping the off cut around the other side of the pyramid beam, while keeping one end attached.

Cabinz have contacted several Disaster & Refugee Shelter charites with designs to make wood shelters insulated & fire resistant

A. Retro fit to existing wood chalets


1. Fire resistant metal skinned insualted sandwich panels with rigid PIR foam core (like Kingspan) panels for walls & roof

2. Dry wall lining c stud & track or purlings galvanised steel cladding . This is to cover timber frame


Peel the flat steel inside sheet from the metal skin sandwich panels ny hand. Alternatively, a mobile horizontal wood band saw can be used to cut though foam

Screw this to the inside of shelters.

The remaining insulated panel can be screwed to the ouside, with metal on outside.

Dry wall lining or purlins (choice dependant on load required) will cover the timber frame beams on the inside

B. New build shelters similar to timber chalets

I am currently prototyping a similar structure, as we speak. Pics will be at blog within a week. Floor is already built here


1. Metal skinned sandwich with rigid PIR foam core (like Kingspan) panels for walls & roof

2. Dry wall lining c stud & track…

Wedge Block Shelter mk. 1 Insulated floor was laid today. A variation of a moving / rolling floor was experimented with.

Floor is approx 3m x 2.15m

 Resting on 2 Metalclad 'pyramid' beams with door edge off cut core of grp / fire resistant plastic . Made of a dry wall lining c-stud 90mm on 92mm tracking beam on bottom.

The galvanised dry wall lining. Middle beam is flat 92mm c-stud

prototype for shelter base being able to move or roller beams
it was mentioned on a hexayurt could be picked up & moved to cover a piece of earth warmed by sun during day to benefit from floor heating at night. 
I thought of a way for heavier shelters like my wedgeblock design to roll on it with concrete fence beams (they have handy grooves for rollers to ride in) with plastic rollers, that were rescued from a scrap yd

Attempt to make a fire resisitant upright & beam from 150mm Purlings & 142mm c stud from dry wall lining . The core is grp composite / plastic core door edge off-cut. 
Tanalised timber  would be a popular choice of core material

This will be combined with metal skinned rigid foam panels that we have in stock (se pic)

150mm Purlings to be used
