Insulate the house with sheep's wool


Sheep's wool is an ecological thermal and acoustic insulator

There sheep's wool it is definitely a choice smart - in the sense of 'intelligent' - forthermal insulation is acoustic dhe buildings. This material, in addition to being natural, healthy and recyclable - in a word, ecological - guarantees excellent performance both in protection from hot and from cold both against i noises. The use of sheep's wool in construction is widespread in Central Europe and in particular in Switzerland, where there are also government programs that encourage the breeding of sheep for the production of wool.

They exist on the market panels is mats insulators that use both a combination of sheep's wool and recycled wool and the sole sheep's wool obtained from shearing. The latter are preferable from an ecological point of view because they bypass the recovery process of the used yarn, with the relative washing. Sheep's wool is hygroscopic, able to absorb water up to 33% of its weight and slowly release the absorbed water, optimally performing the task of balancing therelative humidity of the air.

In the panels for thermoacoustic insulation designed for construction, the problem of poor stability of pure wool yarn is solved by adding recycled polystyrene (usually obtained from the reuse of plastic bottles) to the extent of 20-25%, which constitutes the elastic structure in which the wool is caged without compromising the performance and ecological characteristics of the product. An example of this type on the Italian market is represented by panels LanKot, fully recyclable and compostable.

Sheep wool mats are applicable in the same way as those in mineral fibers (rock wool and glass wool) and represent the most valid and ecological alternative. They can also be used on floors as acoustic insulation and, instead of synthetic foams, for joint insulation between masonry and fixtures.
