Advantages of «RosEcoMat Wool»:
- Ecology and safety — 100% natural product.
- Compatibility with wood — supports a healthy indoor climate.
- Sound insulation — excellent absorption of medium and high-frequency sound waves.
- Hygroscopicity — absorbs and releases moisture without quality loss.
- Vapor permeability — prevents greenhouse effect inside buildings.
- Durability — retains shape and properties for decades.
- Easy installation — lightweight, elastic, easy to cut and lay.
- Energy efficiency — reduces heating and cooling costs.
Unique properties of sheep wool:
- Sheep wool fiber consists of keratin protein molecules.
- Keratin amino acids bind formaldehyde, NOₓ, and SO₂.
- Wool fibers are elastic and resilient: they act like coil springs (stretch when pulled, contract when released).
- Each fiber withstands over 20,000 compressions.
- Keratin molecules inhibit the spread of mold and fungi.
- Wool can absorb moisture while retaining insulation properties (fibers can hold up to one-third of their own weight in water), preventing condensation.
- The scaly structure of the fiber traps dust particles from the air.
- With a sound absorption coefficient of 0.70–1.15, sheep wool provides excellent acoustic insulation, especially effective in the mid-to-high frequency range. In the 500–4000 Hz range, wool mats absorb up to 95–100% of sound.
- The spiral structure of wool molecules reduces sound propagation.
Fire safety:
- Sheep wool does not burn — ignition requires 25.2% oxygen.
- Ambient air contains only about 21% oxygen → burning wool self-extinguishes.
- Ignition temperature of sheep wool: approx. 580 °C.
