When renovating, be sure to properly upgrade insulation
Mar 8, 2015 12:00 AM - Q. We have a family room, originally a porch, that we now use year-round. It is a 3½-inch step down from our kitchen. We are thinking of raising the floor to be even with the kitchen, having insulation sprayed in, installing a subfloor and hardwood floor, and putting in high-efficiency baseboard heat. We seem to have heat loss from the windows.
