Bubble wrap and other insulation products catch on in Korea as temperatures drop
Показать описание
With the drop in mercury levels,... insulation products have been gaining popularity here in Korea.
The products are cheap and easy to install,... but just how effective are they in cutting heating costs?
Our Kim Min-ji takes a look. Bubble wrap,... commonly used to wrap fragile goods,... has been selling well in Korea -- not for its original purpose, but for its insulating effects.
But just HOW effective is it?
In a recent experiment, a window was divided into three parts and one part was covered with a layer of bubble wrap, another with two layers,... while a third part was left without it.
The room was set at 20 degrees Celcius,... the temperature outside was minus 15.
Two hours later,... the part without the bubble wrap had dropped to 13 degrees Celsius, while the part with one layer of bubble wrap was 15-point-5 degrees and the double layered part of the window was 16 degrees.
As the results show,... bubble wrap helps prevent heat loss by about 3 degrees.
"For better results, it would be best not to cover the parts of the window that get the most sunlight,... so as to receive as much solar energy as possible."
Another experiment was conducted to see how effective vinyl insulation film and paper weather strips were in blocking drafts.
After the materials were placed, researchers directed a wind with a speed of five meters per second at the window and measured the pressure of the leaking air.
When nothing was installed on the window, the pressure was seven.
The window covered with wind vinyl had a pressure reading of zero -- meaning it had blocked the draft 100-percent.
The paper weather strip, on the other hand, had a pressure reading of five,... meaning it was only able to block about 20 to 30 percent of the draft.
"A lot of households are placing insulation strips and bubble wrap on their windows. But before doing that, they must block the draft coming in from the windows and doors to make it effective."
So go ahead and try a combination of these simple but effective methods to conserve the heat in your home, instead of worrying about your heating bill.
