Northern Energy Services of Maine Will Make Your Home More Comfortable, Energy Efficient and Healthy.
Adding home insulation to is a sound investment that is likely pay for itself quickly in reduced utility bills. Northern Energy Services only uses borate infused cellulose. http://www.greenfiber.com This insulation is 100% recycled and the borate acts as a fire retardent.
How Insulation Works
To understand how home insulation works it helps to understand heat flow, which involves three basic mechanisms: conduction, convection, and radiation. Conduction is the way heat moves through materials, such as when a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Convection is the way heat circulates through liquids and gases, and is why lighter, warmer air rises, and cooler, denser air sinks in your home. Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy.
Regardless of the mechanism, heat flows from warmer to cooler until there is no longer a temperature difference. In your home, this means that in winter, heat flows directly from all heated living spaces to adjacent unheated attics, garages, basements, and even to the outdoors. Heat flow can also move indirectly through interior ceilings, walls, and floors – wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house. See US DOE Building America Best Practices Series: Insulation
To maintain comfort, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your cooling system. Proper home insulation will decrease this heat flow by providing an effective resistance to the flow of heat.
