A sustainable solution for housing construction

Hemp is transformed into a multitude of construction materials: hemp cement that combines the chènevotte (wooded part of the auction) with lime, patch insulating, including rigid or semi-ririlous panels, without forgetting the insulation en masse or roller that interests us in particular.

Hemp wool performance in isolation

Presentation of hemp wool

The hemp wool is made with long fibers of the plant, meticulously covered and therefore thermalized to form semi-ri-ridden panels or rolls. To strengthen its cohesion and mechanical resistance, sometimes we add a binder, generally polyester fibers.

Among the family of bio -based insulators, hemp wool is going well thanks to its significant thermal and acoustic performance, combined with the exemplary duration. This versatile isolation responds to the most demanding technical standards by offering a particularly favorable environmental evaluation.

Technical properties

Hemp wool are not lacking in technical topics to convince:

• Thermal insulation : View of a thermal conductivity oscillating between 0.038 and 0.042 W/MK, it is easily competed with conventional insulators. His high thermal inertia gives him an excellent phase change, a real resource for summer comfort, significantly delaying the penetration of heat.
• Acoustic insulation : Its fibrous structure and its natural elasticity make it an ally of choice against noise pollution. It effectively absorbs aerial noises and attenuates impact noises, transforming your home into a peace paradise.
• Hygrometric regulation : Of course hygroscopic, it can absorb up to 20 % of its humidity weight without its insulating properties suffering, before returning it when the air moves away. A natural humidity regulator that actually prevents the appearance of mold.
• Sustainability : Resistant to compaction and rot when correctly implemented, hemp wool maintains its performance over the years, without a significant degradation.

Cases of implementation and practical

Current applications

Hemp wool shows a remarkable versatility and adapts to almost all configurations:

• Walls of the walls, from the inside or from the outside
• Attic isolation, lost or mounted
• Insulation of floors and partitions for optimal comfort

Its versatility makes it a wise choice both for new buildings and for renovations, even on the old buildings in which its water vapor permeability respects the natural breathing of the walls.

Environmental and health problems

Reduction of carbon imprint

The analysis of the life cycle of several insulators reveals an undeniable advantage for bio -based materials such as hemp wool. Hemp, in particular, seizes about 1.6 kg of CO₂ per kg of material produced during its growth, largely compensating the emissions related to its transformation. A carbon assessment that makes the insulators conventional balls with envy!

Air quality for health and interior

The absence of irritating fibers and harmful substances makes hemp wool a privileged option for those who care about their inner environment. Unlike some synthetic insulators who can release Covs, it actively helps to maintain healthy air, an important resource, especially for sensitive or allergic people.

To remember to choose the isolation based on the right bio

To make the most judicious choice for your project, keep in mind these few essential points:

• Finely analyze specific needs From your building, taking into account the local climate, the type of walls to be isolated and existing technical constraints.
• Scrupulously control certifications and product traceability to guarantee their real quality and performance.
• Favor the materials produced locally as much as possible To minimize the environmental impact connected to transport and support local economic sectors.

To go further

Two knee insulators and hemp wool are not a simple alternative to conventional materials, but the ambassadors of a global approach to responsible construction, in which technical performance, comfort of use and respect for the environment form a coherent whole.

By opting these materials, you are not happy to improve the energy efficiency of your home: actively participate in the conservation of natural resources and the development of sustainable economic sectors. Your choice of today therefore helps to model tomorrow’s world – a world in which construction and respect for the environment are only one.
