As you may know if you have been following this blog I have been struggling with the heat this year in the can. For some reason this year heat has just been a real problem. In the past, it was not that bad and with both doors open I did not always need a fan to work comfortably. This year though it seems that it has not been as windy as usual and the can has been been getting quite hot even with both doors open and a fan running. Some days lately it has been so bad I have resorted to working in the can after dark.
You have also read about insulation and some of my wondering thoughts about what I am doing. Along with that I have made mention of things I have found while doing research on how to best insulate, heat and cool the can. In that research there was talk too about radiant heating of the can. Basically this all comes down to taking steps to reflect enough of the radiant heat away from the surface of the can without taking away so much that come winter you are working in a refrigerator.
So! I will be installing a roof on top of the can soon. Nothing fancy, I am going to be attaching 2 X 4’s or 2 X 6’s to the top of the can. Then I will lay some pressure treated plywood on top of the 2 by’s and then attach metal roofing material over the plywood. I am planning a slight pitch to one side to aid in water run off. I am also planning a slight overhang one the sun side to at least cast some shade on the can. I have not made a definite decision about which 2 by’s I will be using. One because while I want air to pass under the roof, I do not want to create a cavity that will let high winds topple the can (in the case of a tornado). Maybe I am over thinking this but I have seen the documentaries on how the wind gets under a roof and rips it open. For the most part due to terrain around my place, the wind only comes in from two directions. And while the wind would not be hitting either side of the can straight on I am just concerned as to how a high wind will effect this roof.
By the way…as I stated last time the interior insulation is on hold. Because I need to take care of this excessive radiant heat. A few days ago, while in the can I placed a hand on one of the insulated walls. While it was quite a bit cooler then the bare metal wall. You could feel the heat on the wood.
Either way. I will be sure to keep you all informed on how it goes. Due to my budget this too will be a project done in stages. Plus I have to locate the metal roofing material.
