Technical Description

Insulation works by slowing the movement of heat from a hot space to one that is cooler. Heat moves in three ways: radiation, conduction and convection. Insulation stops these different movements of heat transfer. The insulation absorbs the heat and slows its movement. It is important to realize that insulation does not block the movement of heat, it simply slows it down.

For any type of insulation to work, it needs to be part of an effective system. Insulation should block conductive heat flow (through materials in contact with each other), an R-value is a measure of how well insulation does this. But because heat also moves through convection (air currents), air movement needs to be controlled with an air-barrier system. Additionally, water vapor rides on convective air currents, and tight insulation system prevents this vapor from reaching a cold surface where it can condense, leading to mold and rot.

Air leakage, or infiltration, occurs when outside air enters a commercial office building uncontrollably through cracks and openings. Properly air sealing such cracks and openings in your building can significantly reduce heating and cooling costs, improve building durability, and create a healthier indoor environment.
