Frequently asked questions

Lenoo insulation is an innovative wood fibre-based material that’s designed to provide high-quality thermal and acoustic insulation. It’s made from scraps from MDF panels that would previously have gone to landfill. 
Our exclusive manufacturing process, developed by our team of experts, involves impact grinding and shredding MDF scraps to obtain high-quality wood fibres for insulation. Our manufacturing process results in first-rate thermal efficiency while also significantly reducing the carbon footprint. The result is a carbon-negative material that sequesters 0.338 kg of CO2 equivalent per kilogram of insulation over its life cycle.

Our product has exceptional technical features : 

  • Its density of between 60 and 120 kg/m3 depending on the application gives the building additional thermal inertia that results in superior comfort for all seasons, including in very hot weather.
  • Lenoo insulation has a thermal conductivity of between 0.043 and 0.046, depending on the chosen density.
  • Our insulation is packaged in 15 kg packs for ease of transport, storage and on-site handling.
  • Lenoo insulation boasts exceptional environmental performance, with a reduction in grey energy of up to 50%, compared to other insulation materials on the market. Producing one ton of Lenoo insulation saves the equivalent of 3800 KWh of fossil energy (ADPF Ru f).
  • Classified as fire resistant (class E), Lenoo insulation offers extra protection against fire risks for improved safety.
  • Lenoo insulation goes beyond carbon neutrality: it acts as a carbon sink. Across its entire life cycle, it captures 0.338 kg of CO2 equivalent per kilogram of insulation, making an active contribution to protecting the environment.
  • Superior ecological performance: Lenoo insulation goes beyond carbon neutrality, acting as a carbon sink. Across its entire life cycle, it captures 0.338 kg of CO2 equivalent per kilogram of insulation, making an active contribution to protecting the environment. This helps reduce the overall carbon footprint of your construction or renovation project.
  • Fire resistance: classified as fire resistant (class E), Lenoo insulation offers extra protection against fire risks for improved safety.
  • Effective thermal and acoustic insulation: Lenoo insulation’s optimised thermal conductivity and acoustic insulation features mean that it maintains a comfortable indoor temperature all year round and reduces external noise pollution. The result is a quiet and comfortable indoor environment.
  • Use of sustainable and environmentally friendly materials: made from recycled MDF panel scraps, Lenoo insulation helps cut down on waste and promote the circular economy. In addition, Lenoo reduces damp and mould problems, ensuring a healthy and comfortable indoor environment for everyone.
  • Easy to install: packaged in 15 kg packs, Lenoo insulation is easy to transport, store and handle on-site, reducing the cost and effort of installation.
  • Versatile application: Lenoo insulation can be used in a variety of environments, including residential, commercial and industrial buildings, making it a suitable solution for a wide range of construction and renovation projects.
  • Denser than other loose-fill insulation materials, it provides extra comfort all year round, including in very hot weather.

Yes, Lenoo insulation is perfectly suited for use in a variety of environments, including residential, commercial and industrial. Its versatility makes it an ideal solution for a wide range of construction and renovation projects.
Every project is unique, of course. Our team will work closely with you to understand your needs and meet your requirements.

At Lenoo, sustainability is more than just a word: it’s the driving force behind everything we do. We demonstrate our deep commitment to the environment through a circular approach that aims to boost the insulation industry while protecting our planet.

  • We use the art of upcycling to give new life to MDF waste and create our eco-friendly insulation. These materials, previously destined for landfill, are now being transformed into the foundations of a greener, more promising future.
  • Our conversion process has drastically reduced our energy consumption so as to save natural resources and minimise our ecological footprint. Producing one ton of Lenoo insulation saves the equivalent of 3800 KWh of fossil energy (ADPF Ru f).
  • Lenoo insulation goes beyond carbon neutrality: it acts as a carbon sink. Across its entire life cycle, it captures 0.338 kg of CO2 equivalent per kilogram of insulation, making an active contribution to protecting the environment.
  • Our commitment to the local economy is a core element of our philosophy. Each of our development units is strategically chosen to be close to sources of MDF waste.

Lenoo insulation’s lifespan is closely linked to that of the building where it is used: it will last as long as the building remains standing and is properly maintained. 
If the building is demolished carefully and selectively at the end of its life, the insulation can be vacuumed and reused. Doing this will extend its useful life and contribute to a circular approach. Insulation that cannot be recovered can be composted. 
As for maintenance, the space where the insulation is installed should be kept as dry as possible, as this will help to prolong its performance and durability.

You can buy Lenoo insulation from our partner dealers. A list of these will soon be available on our website.

We can also provide individual quotations to meet your specific requirements.

Fitting Lenoo insulation does require some expertise, particularly for blowing Lenoo into a wooden frame partition. Special training courses are available for you to learn the appropriate installation techniques. These courses are provided by specialist institutes in Wallonia. For more information about the available training courses, please contact us directly.

Lenoo is supported by its financial partners Crelan, Wallonie Entreprendre and Luxembourg Développement, whose shared values include a commitment to the local economy, environmental protection and promotion of the circular economy.

Lenoo receives support from the Walloon Region programme Win4Company to finance our development. Lenoo made a successful application to the ‘GO Circular’ & ‘Circular projects, products and services’ call for projects, in the ‘Launch’ category, part of the Circular Wallonia strategy.

Lenoo is involved in several commercial clusters, including Eco-constructionCap Construction and GreenWin. These partnerships illustrate Lenoo’s commitment to environmental innovation and its desire to contribute actively to initiatives that promote sustainability in the construction sector.

In the medium term, Lenoo is committed to expanding its network of local production units. This innovative strategy is based on a decentralised model in which several small units are strategically located to form a star-shaped network. This ensures proximity to sources of raw materials, reflecting Lenoo’s commitment to sustainability and ecology.
