  • Hi Gary:

    We have completed the box and it is ready to go for this winter. We typically get 300 inches of snow and temperatures well below zero for most of the winter. I have triple insulated the inside with foam board insulation, 3 inches thick on back and sides. I used spray foam insulation to heavily insulated all joints of the box as well. I got the clear twin wall polycarbonate for the front. So it's insulated to the hilt and the top is painted black to help keep ice off the top. The top of the box features a drinking hole. The collector portion is sealed off before the top is put on. I used 20 mil pond liner in the tank side. I'll include the materials list here as well....with lots of pictures. I just wanted to say that I am a NOVICE person and a female at that and I found this very easy to construct. Thanks so much for this wonderful idea. I will be recording the weather and the performance of the box over the winter. I'll send this along come spring. The box measures 45"X33". (holds a lot of water)


    The liner.
    It looks like Freedom used the nails with
    the large, plastic heads to hold the lining
    in place --  this seems like a good choice.

    trimmed.
    The liner is 20 mil PVC pond liner.
