Fibra Natur Sup’Air Laine is a 100% pure sheep wool insulation roll, developed for thermal and acoustic insulation of unused attics, suspended floors, and horizontal cavity applications. Naturally breathable, hygroscopic, and vapour open, this product also acts as a VOC absorber, improving indoor air quality while offering excellent thermal resistance (λ = 0.035 W/m·K).
Manufactured using SheepsWool wool, Sup’Air Laine is a natural, sustainable alternative to synthetic insulation materials. Its flexible form allows for easy cutting and installation, and the wool naturally regains its full loft after unrolling, ensuring consistent thermal performance.
