How do you tell if your house is well insulated?
Understanding insulation involves understanding heat flow. A basic rule is that heat energy transfers from hotter places to colder places. Conduction is a word you’ll hear in this industry and conduction occurs when heat moves through solid matter.
Insulation works by slowing conductive heat transfer. It does this by trapping air in the insulation material and keeping the air from moving. You will know your insulation is working if it cost and takes little energy to keep your home comfortable.
