I'm writing from South America, and we want to build a cold room to keep peaches for a couple of weeks. Unfortunately the panels here are too expensive, can you give me some tips to insulate walls and roof without using panels? Thanks, O.U.
Our web site has a publication on small scale cold rooms and it has a plan for a farm-built cold room. See <http://ucce.ucdavis.edu/files/datastore/234-701.pdf. It uses wood frame construction with fiberglass insulation. If these materials are available, you should be able to build your own room. You can use the general design concepts to build a larger room than is described in the plan. Also posted in our new postharvest video library is a short video detailing the construction of cold storage for small scale produce handlers. -Jim Thompson
