Discovering The Importance Of Insulation
There are two ways to moderate the temperature of a house compared to seasonal swings in hot and cold weather. The first and more primitive method is to take advantage of thermal mass. This means using thick walls to absorb variations in temperature in order to balance an interior temperature that is warmer at night and cooler in the day. While this is still effective, it is more expensive to build houses with heavy walls.
The modern solution is to use fiberglass insulation. A home can be build using the lightest materials and yet stay warm or cool with much greater efficiency than homes in the past. This is largely due to increased use and sophistication of insulation to control all areas where heat transfer can occur. While it costs more money to improve the insulating properties of a home, it is a one-time cost. Electricity for the air conditioner is an ongoing cost.
Most insulation is in the walls, and older homes have adequate protection. Since glass fibers do not decay, they should not need replacing for the lifetime of the home. It is still possible to add an extra layer of fiberglass or else add a mat layer to the inside wall to provide one more barrier to the outdoors. Upgrades like this are often cheaper than changing the air conditioner and accrue whenever a new unit is purchased.
Of course, there are many cracks and surfaces that are not protected. One might be the ducts the hot and cold air pass through. These passages are usually located under the house and benefit from the moderating annual temperature of the earth, but sometimes an HVAC expert will recommend changing or improving insulation in the ducts. Since cold air might contain condensed moisture, replacement might be a health consideration.
Most unavoidable heat transfers occur through windows. This is unfortunate, since windows provide sunlight as well as access points for fire fighters. The problem can be mitigated by adding an insulating layer to the inside or outside of the house. This might be a piece of layered plastic used in greenhouses. A more attractive solution is to purchased double pane or layered windows.
Many services offer to replace old windows with new ones that are as practical as the old but contain an ultralight layer that acts as a thermal barrier. This type of insulation is high-tech, and it permanently increases the value of a home. Many newer houses employ these energy-saving innovations even while they are manufactured with lighter materials and more sparse skeletons. Your house could reduce its electric bill by a quarter or more with better insulation.
