It's beginning to be reliably cold at night. We are busy getting ready for winter. We've wrapped the water line with heat cable and insulated it and put the flexible sewer line inside a PVC pipe.
As we were renovating we insulated the back walls of all the cupboards and closets with a material called Reflectix. We brought enough Reflectix with us to make covers for the windows. We plan to put these on just after sundown and take them off in the morning.
We started making these covers a couple of days ago. For the last few days as soon as the sun went down the temperature started to fall very quickly. It would be a very pleasant 75 degrees F inside when the sun went down and fall eight or nine degrees within an hour. This means we have been turning on the smaller of our heaters almost as soon as the sun went down. Still, even at what should be a toasty 72 degrees we felt cold because the warm air inside was hitting the cold glass of the windows, cooling and creating a draft.
So we began putting the Reflectix on the windows yesterday by covering the two sun vents, and making covers for the bathroom window and the window above Tony's bed. Today we made a cover for the window above my bed, and for each of the large side windows in the front. We still need to cover the two largest windows in the trailer, the ones in the front.
Even so, the difference is encouraging. Two hours after sundown, and covering the windows, the temperature has fallen by less than half a degree. The cold draft is all but gone. It's supposed to fall to freezing tonight, so I'm sure the weather proofing is going to be appreciated.
