Insulate the attic

The attic is a massive open door that lets cold air in continuously and unobstructedly. Insulating the attic is one of the most effective techniques to limit heat loss and, thus, the amount of work your heating system has to do. The purpose of insulation in an unfinished attic is to keep the rooms below cool in the summer and warm in the winter. That implies merely insulating the attic floor and installing roof vents. Insulation in a finished attic must help keep the attic sections comfortable.

To prevent heat from escaping from your heater, add at least R-38 insulation (10"-14" deep). If only the living space is to be insulated, wrap the insulation around the room's walls and ceiling before continuing along the non-living space's floor. The area behind the knee wall will be excessively hot or chilly in this instance. Apply insulation from the roofline all the way down to the floor to keep the area behind the sidewalls from freezing in the winter. Alternatively, you can place weatherstripping around the attic entryway and guarantee appropriate venting to avoid moisture retention.
