nir-vana innovation network

Founded in 2011 by 3 engineers, the Belgian company specializes in the manufacture of hemp blocks and is growing steadily. The company has both private and public investors. These investors are also strategic partners for the future development of the company which has recently become the world leader in hemp blocks. The hemp block is a non-load-bearing glued masonry product designed for the production of healthy and natural insulating envelopes, partition walls and counter-partitions. Very versatile, it is highly appreciated by professionals for both new construction and renovations, whether they are single-family, collective or tertiary projects. Advantages : 1. Thermal regulation The hemp block naturally regulates the temperature of the building thanks to its ability to diffuse the accumulated heat. This high inertia insulating block protects: o cold in winter by keeping the heat in the house longer o hot in summer by avoiding overheating of the habitat. As a real thermal buffer, it maintains a constant indoor temperature and significantly reduces the impact of heat variations between day and night. 2. Humidity regulation Thanks to its high permeability to water vapour, the hemp block acts as a water buffer and offer a constant and healthy indoor climate for the occupants. The relative humidity level is thus stabilised (from 50% to 55%). Its uses: o Renovation and insulation of old buildings, old brick or damp walls o Interior renovation to insulate walls on which wooden floors are resting, prevent any condensation issues in the transition areas between materials to guarantee the excellent conservation of the building o Humidity regulation in commercial projects where humidity variations are high: archive rooms, museums, sports halls, swimming pools ... 3. Acoustic Insulation Whether the hemp blocks are used for walls or interior partitions, external and ambient noise will be significantly reduced. In terms of sound insulation, the hemp block acts as a real sound trap and helps to dampen the majority of sound waves, protecting from noise pollution. 4. Protection and fire resistance The hemp block complies with current standards and provides a simple and effective solution to your site problems, both for industrial or collective buildings (nurseries, schools...) and residential homes. With an excellent reaction to fire (class B-s1 d0), it offers up to more than 2 hours of fire resistance depending on the finish and thickness of the block used. 5. A 100% natural solution: The hemp block meets the strictest requirements of sustainable development: it is manufactured according to a very low energy-consuming process, using 100% natural materials (limestone and hemp) that are sourced locally. A very positive carbon footprint, since a pallet of IsoHemp hemp blocks stores 100kg of CO². 6. Other advantages o Flexible design o Ease of implementation o Wide choice of finishing : brick, roughcast, cladding… Technical data :  Thermal resistance : from 1 to 5 m2K/W  Thermal conductivity : λ = 0,071W/mK  Fire resistance : from 60 to 120 minutes  Phase shift : from 4 to 24h  Acoustics : sound reduction from 37 to 45 dB  Resistance to compression : 300 kPa The company, which employs around 40 people, is already present in France (where it has a subsidiary), the Netherlands, the Grand Duchy of Luxembourg, Israel and Australia, and would like to expand into the German and British markets as well. The company's target clients are : o Architects o Engineering offices o Distributors
