This home is almost done. Some of the finishing touches are being done at this very moment. As shown, there were plenty of gaps and cracks where the cold winter air could seep right in. Now that it is spray foamed, you almost don't need a heater in the home. Once it's warmed up, it stays that way for quite a while. Just imagine what is behind your drywall. How many places are there that you would be able to see right to the outside? Those gaps and cracks are where your money is going. Now I'm not saying tear down your drywall and look for dollar bills. Just pull out your energy bills and see how much you are actually spending to heat and cool your home. Now imagine that getting adequate insulation would drastically reduce your bills. Would you do it? Or would you continue to throw your money in the garbage?
