However, it may need replacing or retrofitting sooner depending on the type of insulation installed, the R rating of the original insulation, compression and movement over time, and whether any damage has occurred.
Do bricks insulate well?
Although bricks have natural insulating properties with an R-value of around . 80, it’s not nearly enough. Insulation along with brick is the best way to insulate a home and lower energy costs. The type of insulation you should use may vary depending on the age of the house and how it was built.
Is a dollar bill a conductor or insulator?

How do you insulate outside walls?
To add insulation to any exterior wall, holes are drilled between the studs of the existing walls. Then, spray foam, cellulose, or another form of loose-fill insulation can be blown in to fill up the wall cavities. Finally, the holes must be plugged up and refinished to match the rest of the wall.
Does ac drain line need insulation?
