Hemp: a noble product Hemp is a material renowned for its types of insulation with the lowest C02 'It requires little water and no 'It absorbs a large quantity of C02 during its growth cycle ' It makes good use of poor-quality >lt plays a productive role in crop rotation (biodiversity, soil production chain 'Compared to mineral wools, plant-base insulations require very little energy to manufacture, which helps reduce C02 emissions. ' Biofib' insulations are produce by a complete production process: -from crop growing in the Vendee region (near the manufacturing site) - to the production of batts or rolls (fibre extraction and overlaying at the same site, meaning less 'Biofib' insulations display a very positive carbon balance, helping to achieve "double" energy savings and Biofib' ouate is an insulation composed of natural hemp and recycled cellulose fibres, all specially suited to thermal and acoustic insulation of residential and commercial It is packaged in the form of semi-rigid batts Biofib'ouate is mainly used for thermal and acoustic insulation of solid walls, roof structures and floors, whether newly built Ecological, healthy and non-irritant insulation product ^) Enhanced acoustic comfort (Q) Batts "spring effect" = easy to install of the hemp/cellulose wadding mixture • Very strong hemp fibres that provide rigidity and proper mechanical resistance. • The two fibre structures complement each other for better acoustic efficiency. • Cellulose wadding: a recycled raw material, derived from the re-use of unsold or recycled newspapers. • Quality control of the raw material • Low energy consumption in production European Technical Thicknesses / packagings Technical Specifications Thermal capacity Thermal conductivity by weight Thermal resistance Water vapour diffusion resistance Water vapour transmission Airborne sound reduction > 61 (- 2; -7) Timber-frame wall / Biofib'ouate 140 mn / Fermacell > 47 (- 4; -11) Partition 72/48 Fermacell / Biofib'ouate 45 mn / Fermacell > 69 (- 2; - 7) Partition (double-skin) Fermacell / Biofib'ouate 45+60+45 mn / Fermacell High acoustic wadding with hemp fibres provides Biofib' ouate with excellent sound insulation properties to give enhanced acoustic comfort. The measured and certified noise-reduction levels (FCBA tests) on standard walls are clearly superior to regulatory requirements.
