As it's not practical to ship expanded foam as it taks up more volume, and the supply of composite door panels off cuts is limited, I decided to combine the 2 & make a protoype machine using a frame & silver foil.
A similar, previous experiment with expanding foam , Frame & grp sheet / window is HERE ( Mk 1 & 2 DIY SIPS Framed Panel with GRP Skin & Built in Window )
This was the cheapest way i could think of for making a basic panel. TO protect the oustside of the panel from the wind / rain. a metal or grp sheet can be attached or glued with foam from the start.
If a green house wall type shelter is required for growing veg, a wider frame can be used & shelves attached to hold plant pots. a grp sheet with removable fixing can then ba attached to the outside
Basic fisrt attempt at a prototype Diy Sips (structual insulated panel) machine. It's using grp skin foam core composite door off cuts as hinged holding panels
A plastic sheet & foil sheet would normally be placed underneath, But this pic is to show frame make up
Close up of frame construction , Corner braces screwed with collated dry wall screws
Corners glued & screwed with a 70-8mm 5 torx swcrew & 55mm drywall screw
Plastic sheet placed on base to protect from foam leakage
place plastic sheet on top of foil
Close top panel of machine press
6 cans of foam used (could of used 7-8, but was not sure of voume) temp was cold, so did not expand as much as hoped
Put heavy items to weigh top panel down, to counteract foam expansion pressure

Plan to make a low cost hardware kit to allow low income groups to build locally sourced (preferably reused) panels to make foldable shelters like Hexayurts, or for childrens play dens, animals pens or room dividers to reduce heating costs and noise
