did not know where else to post this, but I am sure here someone can help.
Besides insulation such as fiberglass, cellulose, styrofoam, what material similar to maybe a plastic will not absorb heat or deflect it in order to build something. Styrofoam seems to be the best after my research but it will crack or not last.
Something that I can use to build a medium size storage unit outdoors that will not break if wind throws objects around such as small rocks during storms. This way the contents of the storage will stay fairly warm (maybe 80-85) and not 102 degrees Fahrenheit.
Also something shiny would hurt the eyes/be difficult to look at outdoors if the entire structure was made with reflective sheets so reflective aluminum is not an option and there are no trees around.
Right now I have a plastic storage unit and the temp. will go above 100 Fahrenheit (I used a thermometer to check). So in a nutshell, I would like to build a big box that resists/deflects/does not absorb heat with durable lightweight material.
Thanks!
