Insulation
* All insulation is based on the ability to trap air.
* Most insulation contains plenty of chlorides and piping is frequently under tensile stress
  - creates air infiltration barriers
  - is applied after buildings are enclosed
  - reduces conduction
  - saves energy
  - traps excess heat
* absorbs and neutralizes acoustic energy to keep it from radiating out of the nightclub.
* also helps prevent interference.
* also reduces heat loss from the skin
  - the risk of condensation buildup
* becomes wet and looses it's resistance to heat loss.
* can also act as a sound absorber or barrier, keeping noise levels down
  - extend the range of electric vehicles by reducing the load on their batteries
  - save money and make the house more comfortable at the same time
* comes in both natural and unnatural forms.
* covering the nerve is called the myelin sheath.
* cuts down on heat energy transfer out of the building via conduction.
* does cut down on fuel costs.
* does, however, have an impact on winter heating load.
* draws a repeating wave pattern between a pair of boundary lines.
* eliminates interior condensation and dripping in spring, summer and fall.
* factor that is usually disregarded when deciding on window covering products.
* helps control and maintain a home's temperature
  - create a more uniform temperature and can eliminate that problem
  - keep homes cool in the summer, and warm in the winter
  - maintain water temperature throughout the cycle, as well as minimizes noise
  - to block conduction of heat
* holds the electricity in the conductors and protects the conductors from damage.
* includes sections.
* is also important to energy efficiency.
* is an abrasion, moisture and heat resistant black cross-linked polyethylene
  - effective means of conservation
  - any material that reduces the rate of heat transfer from one area to another
  - beneficial in that it helps maintain a uniform temperature throughout the home
  - cardboard paper and old newspapers
  - construction materials
* is designed to keep heat out during the summer and to keep heat in during the winter
  - prevent heat flow
  - especially important to seals because of the high heat capacity of water
  - foamed in place for added strength and cold keeping
* is important for summer cooling
  - in a garage door for many reasons
  - in the process of being installed
  - insulating materials
  - insulation and more insulation equals more insulation
  - isolation
* is located in attics
  - houses
  - lofts
* is made from such nonconducting materials as plastic and paper pulp
  - of foam
  - measured in R-values
* is one of the building materials damaged by hidden leaks
  - most cost-effective, energy saving building materials available
  - part of copper wiring
  - placed so that heat is directed toward the surfaces most affected by ice
  - protection
  - provided by specialized cells called myelin that wrap around the axon
  - rated by R-value, the resistance to heat flow
* is rated by R-values and expressed in terms of resistance to heat
  - expresses the resistance to heat
  - sunlight resistant
* is the key to an energy-efficient refrigerator
  - process of keeping heat or cold from moving from one place to another
* is used to avoid losing heat energy
  - keep hot things hot and cold things cold
  - stop heat energy transfers from buildings and the human body
  - very important for achieving good space heating
  - vital to maintain even temperatures in a passive solar home
  - what prevents or slows down the movement of heat
  - wrapped in plastic to hamper dampness within the interior of the house
* keeps heat from flowing out of the hot water and into the room.
* maintains more heat in the equipment and transmits less to the environment.
* makes a huge difference when it comes to steam mains.
* material that has the ability to store heat
  - used to slow down heat flow through a building s envelope
  - with the ability to store heat
* needs to have air moving around and through it to work at all.
* only works when it is installed in an air tight configuration.
* prevents outside air from getting in and inside air from getting out.
* protects valves, pipes, control enclosures from moisture, freezing.
* provides R-value and aids in temperature control within a building
  - functions
  - warmth
* refers to a material with the ability to store heat.
* retains the heat for use during the night and on cloudy days.
* retards the rate at which heat conducts.
  - money and our nation's limited energy resources
* serves to both prevent heat loss in the winter and heat gain in the summer
  - keep a home comfortable and reduce costs for heating and cooling
* slows the rate of heat flow from a warmer to a cooler area.
* thoughout the home helps manage energy use.
* works wells to stop thermal heat, but is ineffective against radiant heat.
+ Axon: Anatomy of the nervous system
  * The electrical signal of an axon is made by ions that flow in and out of the cell in a chain reaction called an action potential. The speed at which the signal travels depends on how thick the axon is, and how much insulation it has. Insulation is provided by specialized cells called myelin that wrap around the axon.
