Corkboard Insulation

Posted on

Corkboard insulation is manufactured from natural cork which is reduced to granules. The granules are graded into sizes and agglomerated by pressure and temperature, without the addition of any foreign substances.

Cork is lightweight, compressible and expandable. The honeycomb structure allows air to permeate the crevices and basically take up residence. This contributes to the insulating properties of cork. The cell walls are flexible, strong, waterproof and airtight, resulting in an insulating material with a low density. Due to the structure of the cork cells, it is not only a thermal insulator, but an acoustical one as well. Because the substance is flexible and air-filled, it is cushioned.

The gases and air inside cork are separated and sealed from each other within its cell-like structure, so it does not conduct heat, sound or vibrations easily. Cork is also resistant to rotting, moisture, fire and dust. Cork is very durable, which is another property that lends itself to flooring and walls. It comes in sheets, tiles and rolls, as well as in the form of wallpaper.
