Our home was losing heat through the garage, that is the room above the garage was much colder than the rest of the house. Canadian Foam Insulation suggested using 2lb Polarfoam to prevent heat from escaping through the garage ceiling. They gave us a great estimate compared to a couple of other competitors we enquired with. On the day of the job, they came, removed the drywall , sprayed the foam, put the drywall back and finished the job in one day. They also cleaned up after they were done. All aspects of their service was exceptional and I wish I had done this earlier.
