The insulation between the rafters will not do any good, because the attic must be ventilated, and the beam insulation must be between two unheated spaces. You can add insulation to the floor - the more the better. Don't put it on the eaves. In addition, make sure that the attic is well ventilated.
Should you insulate the roof of your attic? Insulation is a good choice to increase the energy efficiency of your home. Quality insulation will make it more cost-effective to heat and cool your home. Department of Energy estimates range from 10% to 50% savings, depending on several factors. However, attic insulation is not just about heating.
Proper attic insulation can also keep the roof in better condition by helping to prevent ice build-up and condensation. On the floor they are called joists, on the ceiling they are called beams. Yes, you can isolate yourself on the rafters, but it's more complicated. Loose-fill insulation is usually less expensive to install than batting insulation and provides better coverage when properly installed.
This will allow you to perform air sealing, check the condition of the insulation and check if there is a vapor barrier. For optimal energy efficiency, your home should be properly insulated from roof to foundation. If there is not yet one, it should be acceptable to install insulation if there is no evidence of moisture problems, if the humidity levels in the house are reasonable, and if air leaks are sealed through the roof into the attic. I think what I've learned is that if you're not going to finish the attic area and the walls of the finished room are insulated, you don't have to insulate the ceiling joist, but you do need to insulate between the floor joist and the finished walls.
It is very beneficial to consider whether you could benefit from better insulation before installing a flat roof. It is best to locate the access door to the mezzanine inside the house through the basement, unless you build and maintain an airtight and insulated access door on the perimeter wall. You can purchase air ducts that are fastened to the inside of your roof above the eaves vents and that fit between the rafters of the siding to maintain the ventilation air gap and then fill in between this foam board and the insulated attic floor (see Figure 5-2.An alternative measure to prevent ice accumulations is to make the roof waterproof by using a self-sealing membrane under the shingles. In addition to checking for structural problems, check the condition of the roof structure, siding, finish, and soffit and fascia for signs of moisture problems such as leaks, stains, mold, peeling or rotting.
For example, attic hatches do not have much space for insulation, but they often contribute greatly to heat loss, making them excellent candidates for rigid foam panels. One telltale sign of air leaks is insulation discoloration, so feel free to look under existing insulation to locate air leaks. When obstructions, such as a lattice ceiling, make the above method too difficult, install a polyethylene air barrier or a low-permeability foam insulation plate between the joists. Where the roof of the attic touches the ground, around the edges of the attic, there is often not enough space for much insulation.
