Building an "Insulated Wall Greenhouse" to make a trailer more attractive & insulate its' contents 

Plain Trailer

2 options .Option A. insulated panel is held in place with  Metalclad frame. Frame supports grp fibreglass corrugated roofing panels (lets 90% of light through)

Tall plants are grown behind the sheeting. Sheeting is removable via nuts on beams ,and will likely have a joint in the middle..  

Option B Metal clad beams & composite door off cut shelves insualate trailer & provide shelving for plants. White surface reflects light to plants.

Window boxes could be made of offcuts on each shelf to hold soil so no flower pots are needed.

Removable corrugated grp fibreglass sheets cover  shelves & protect plants
