Sheep’s wool is the least flammable of all natural fibers due to its high nitrogen content. The ignition temperature is 560°C, which is approximately twice hotter that the one of wood (270°C). For combustion, an oxygen content of min. 25% is needed. Because in the surrounding air the oxygen content is only 21%, the flames are strongly inhibited.
It does not require any flame retardant substance and therefore does not generate toxic gases in case of fire. The LanaTerm insulation practically acts as a fire barrier.
The R value indicates the resistance to heat flow. The higher the R value, the greater the insulation strength. The R-value of the LanaTerm insulation is at least equal to or often better than the one other insulation materials have.
LanaTerm can absorb one-third of its own weight in moisture without losing its insulation properties.
LanaTerm has a hygroscopic effect, which means it adapts very quickly to the humidity of the surrounding air and absorbs moisture when the humidity is higher than the specific humidity of the wool. If the air in the room is too dry, it releases the moisture back into the room atmosphere.
The noise reduction factor is the average of noise absorption coefficients and it ranges between 0.85-0.95. A noise reduction factor that is = 0 indicates a perfect reflection and a noise reduction factor that is = 1 indicates perfect absorption.
Wool improves the air quality inside. Buildings often contain contaminants (VOCs) emitted by newly installed materials or furniture. The special effect of sheep’s wool fiber can permanently bind chemicals such as formaldehyde, sulfur dioxide, nitrogen oxides and remove them from the air.
Sheep's wool is the least flammable fiber because of the high nitrogen content. The ignition temperature is 560°C, which is approximately twice hotter than the one of wood (270°C). For combustion, an oxygen content of min. 25% is required.
Wool manages humidity, LanaTerm can absorb one-third of its own weight in moisture without losing its insulation properties.
Wool fiber is unique in its ability to simultaneously reduce environmental noise, contact noise and sound transmission.
One of the main reasons we love the sheep’s wool and we recommend it so much is that it is very easy to work with it.
Sheep's wool is sustainable. LanaTerm is a 100% natural product. Since sheep naturally produce wool, only a fraction of the energy consumption is required compared to the energy consumption required to produce other equivalent types of man-made insulation.
Sheep's wool is an invention of nature with properties that no synthetic fiber can copy. Using LanaTerm will significantly reduce heat loss, lower energy costs, and increase the comfort.
