Duct insulation in your home is a simple method of achieving better energy efficiency, thereby creating less work for your HVAC system, and improving your comfort by keeping your home at more stable temperatures. Insulation in your home provides resistance to heat flow and reduces your heating and cooling costs, enhancing your comfort by providing an effective resistance to the flow of heat.
To maintain comfort in your home, the heat loss that occurs in winter has to be substituted, and the heat obtained in the summer has to be taken out by your heating system. Therefore, properly insulating your home will decrease this heat flow by providing a powerful resistance to the flow of warmth, increasing your comfort at home and your well being.
Insulation materials range from bulky fiber materials such as fiberglass, rock, slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Most common insulation materials slow down conductive heat flow, and to a lesser extent, convection heat flow. Radiant barriers and reflective insulation methods function by reducing radiant heat away from living spaces, making them especially beneficial in cool climate.
