Searching for a way to save money on electric/gas bills? Its important to learn how insulated window blinds can help block heat conduction, convection and radiation from the sun during hot summertime heat waves
Denver, Colorado – When trying to save money on monthly utility bills, it is important to understand how energy or heat flows into and out of a home’s windows. As pointed out in the graphic above, it is very important to understand three home energy terms: conduction, convection, and radiation.
Radiation is the transfer of heat through open space by electromagnetic waves from the sun. This type of heat radiates in a straight line from a source to a cooler area.
Convection is the transfer of heat by the movement of liquids or gases. Commonly, this is referred to “air infiltration” or “drafts.”
Conduction is the transfer from one molecule to the next. A house loses most of its heat via conduction. Conducted heat travels from one molecule to the next and travels like a spill soaking into a paper towel: it spreads. The rate of conduction depends on the type of material. If you place a metal rod near a fire, you will quickly feel the heat at the other end. This is because the rate of conduction is high and the rate of resistance is low. Try the same experiment with a wood rod and it would take much longer to feel the heat at the other end due to wood’s lower rated of conduction.
Conduction is also the reason that a tile floor will feel colder to a bare foot than a bathroom rug. Tile is a faster conductor, so the heat from the foot transfers to the tile much more quickly. The cold sensation felt by the skin is due to heat loss carried away by conduction.
Insulated Window Blinds work by blocking the cold/heat from seeping in through the windows via conduction and convection and one side of the insulated foam is coated with a sheet of radiant barrier foil that reflects the UV rays instead of letting them penetrate the window.
