The answer is yes, it is a very good insulator with lots of popular applications. This is because it is made up mostly of air, is cheap, and is very durable. It works as an insulator by trapping heat in its many air bubbles, which prevents it from transferring to other surfaces and mediums through convection.

To understand why cork is a good insulator of heat, you just have to look at where cork comes from. Cork begins life as bark, protecting the trees it shields from fire and harsh temperatures. That’s one of the reasons why cork is one of the most effective heat insulators around.

It might seem strange to apply ice as an insulator, but it can help when old leaky single-pane window frames are cold enough to develop frost inside the home. An application of water from a pump-spray bottle can form a glaze of ice, which seals air gaps around edges of window panes and frames.

Fiberglass (or fiber glass)--which consists of extremely fine glass fibers--is one of the most ubiquitous insulation materials. It's commonly used in two different types of insulation: blanket (batts and rolls) and loose-fill and is also available as rigid boards and duct insulation.. Manufacturers now produce medium- and high-density fiberglass batt insulation products that have slightly ...

Insulation level are specified by R-Value. R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home.
