Well, with winter coming I'm scrambling trying to cut the heating bills! Last year the final fill of the fuel oil tank was $620 , and that will only last a month and a half! So, i bought a cast iron pot belly stove that will go in the kitchen, and to be sure the heat from the stove makes it through the house, I tore out the wall between the kitchen and living/dining room. While doing so, I opened up the exterior wall and noticed there is no insulation in the walls!! Holy crap! Who builds a house in Ohio with no freaking insulation? So i replaced the drywall that will be behind the potbelly with the fire resistant drywall, and bought some pink r-19. As far as the rest of the house goes, I plan on using blown insulation in all the exterior walls, and since the walls aren't drywall (fiberboard, cardboard kinda stuff), I'm going to just get me a whole saw and blow it in from the interior of the house, then just put the holes back in using duck tape. That will only be temporary as I plan on installing 1/4" drywall over all of the interior walls in the house as it is! So, I'm going to spend a bit of money to get ready, but I'm hoping the money saved will be considerable! What are all of you doing to get ready?
