3 Things You Didn’t Know About Insulation

3 Things You Didn’t Know About Insulation
  • Opening Intro -

    Insulation keeps our homes from the harsh thermal impacts of extreme weather.

    You might not give this home feature much thought, but its role is important.


Energy-efficient insulation helps you heat and cool your home for less, helping put money back in your wallet each month and conserving the earth’s limited resources.

Here are three interesting facts you might not know about this critical home component.

Insulation Can Begin as a Liquid

Certain types of insulation material, such as spray foam roof insulation, actually begin their life as a pressurized liquid in a chamber or can. When it’s time to install the insulation, the liquid is released through a specialized nozzle and expands to fill the space it’s sprayed on.

This helps save large amounts of time, since the material can be applied directly to the surface. It also helps eliminate material waste, because unlike insulation sheets, it does not need to be cut to fit.

It may also fill gaps better (especially small nooks and crannies), making it a great solution for tight or oddly-shaped spaces.

Insulation Might Have Had a Past Life

Insulation can be made of a variety of materials. One form of insulation is made of recycled denim. The scraps from denim manufacturing, bits from cotton processing and sometimes pre-worn jeans are shredded and turned into a wool-like material that can be used in the same way that fiberglass or mineral insulation is used.

Because it is recycled, it helps reduce waste that would otherwise wind up in a landfill.


Insulation Can Be Grown

Rigid cork may be used as insulation material as well, which means that this particular option is renewable and sustainable. Cork is composed of the outer bark of a certain evergreen tree called a cork oak.

The bark can be harvested repeatedly every nine years without harm to the tree. When used as insulation, it performs very efficiently. This is a great choice for eco-conscious builders since it’s totally natural and contains no harmful chemicals.
