Our house is appx. 100 yr old Farm house w/70 pecan trees. My DH put a false wall outside the house with new hardy board siding so we should be nice and warm this winter. He built a frame and then put tarpaper inside each and insulation and then the siding. So for in our 105 deg. temp. and the dust storms and 70 mph winds we stay cool ; so we will see what the winter will bring. We found out the metal roof was not sealed and had it sealed to keep dust and wind out. (did not know about metal roofs). Our problem here is not being able to find anyone willing to work at anything. even offering high pay and working with them does not work.
