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

A. Retro fit to existing wood chalets

Materials

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

Method

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 cabinz.net blog within a week. Floor is already built here

Materials

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

2. Dry wall lining c stud & track or purlings galvanised steel cladding, combined with grp / fire resistant plastic off cuts or tanilised wood . We call this metalclad

Method

Build metalclad frame on base with drywall lining steel cladding or purlins if stronger frame required, possibly on concrete post fittings (see below)

Cut to size & screw overlapping sandwich panels to frame for walls & roof. Floor can either be like this or with metalclad frame , insualted panels then clad with steel.

Footings

I was not sure how & if the chalets are attached to the ground.

A method I am testing currently, is using 2.7m concrete fence posts as they are fire resistant, heavy, strong, cheap to buy @ £10

Rebar loops or L shapes attach them to the chalet & ground , These concrete fence posts may need to be strengthened with purlings / dry wall lining, depending on load.
