Abstract
The invention relates to an insulating material which comprises a first layer of an essentially non-hygroscopic fiber material and a second layer of an essentially hygroscopic fiber material, said first layer being located adjacent said first zone and said second layer being located adjacent said second zone. The insulating material is characterized in that said first and said second layer are made of a highloft nonwoven material with a density of from 5 to 125 kg/m3.
Claims16
An insulating material comprising a first surface and a second surface, said first surface, when in use, being in contact with a first zone having a first temperature and a first absolute humidity, and said second surface, when in use, being in contact with a second zone having a second temperature which is lower than the first temperature and having a second absolute humidity which may be different from said first absolute humidity, said material comprising a first layer of an essentially non-hygroscopic fiber material and a second layer of an essentially hygroscopic fiber material, said first layer being located adjacent said first zone and said second layer being located adjacent said second zone, characterized in that said first and said second layer are made of a nonwoven material with a density of from 5 to 125 kg/m3.
