About Wood Wool

All-in-one solutions

Heraklith wood wool insulation is a natural product that combines fire resistance with superior acoustic and thermal performance in a durable and eco-friendly product which provides an all-in-one, no-compromise solution for your insulation needs. It is available in a variety of surface textures, colours, and sizes that allow you to customise its use to meet a wide array of design requirements.

You can use Heraklith wood wool insulation boards in a variety of applications, such as ceilings, external walls, loft floors, pitched roofs of residential or non-residential buildings, agricultural buildings, and even neighbourhoods in proximity to railroads and other sources of noise. And in addition to their primary features of fire resistance, acoustic and thermal performance, durability, and eco-friendliness, they are easy to install and reduce construction time, because their surfaces are pre-finished. They are also naturally attractive, moisture proof, and mould resistant.

Features

Among the many features of Heraklith wood wool insulation boards, five stand out:

Product properties

  • Fire resistance

    Fire resistance

    The intense heat of a building fire can affect not only the material being burned but the structural components of the building itself causing significant damage to its support structure and endangering the health and safety of its occupants. To protect against such damage and danger, it is important to…

  • Acoustic performance

    Acoustic performance

    Protection from noise plays an important role in the comfort of any modern living or working environment. And Heraklith offers a wide variety of insulation solutions to help create quiet and undisturbed home and workspaces, especially those above underground garages, in proximity to technical rooms, and in other places that…

  • Thermal performance

    Thermal performance

    The most important reasons to insulate a building space include the need to improve its thermal level of comfort and reduce its energy use. Insulation lowers the cost of heating and cooling the space and reduces CO2 emissions and their associated stress on the environment. When used in buildings, thermal…

  • Durability

    Durability

    Wood wool insulation is naturally durable and can last for the life of the building in which it is used. Heraklith wood wool insulation boards fit easily into a tight ceiling application, and the high resistance to impact of the wood wool surface ensures optimal protection against physical damage.

  • Eco-friendliness

    Eco-friendliness

    The best insulation products are created and used with commitment to environmental responsibility and Heraklith wood wool insulation boards are no exception. They are made depending on availability from PEFC or FSC certified spruce wood that originates in production forests.

Accessories

Installation accessories

By offering attractive surface options, Heraklith wood wool insulation boards speed up construction time, because the insulation and finishing steps are completed in one operation. To ensure the attractiveness of any installation, Heraklith offers metallic fasteners that match the surface colour of the boards to make the installation hardware as invisible as possible.

Installation accessories

In most areas, the installation instructions may be found on the top cover of the packaging. (Note: This might not be available in all countries, please check on the local websites.)

Environmental impact

Heraklith wood wool insulation boards stand at the forefront of environmental responsibility in production and building construction. Whenever possible, we use wood certified by the Programme for the Endorsement of Forest Certification (PEFC) and/or Forest Stewardship Council (FSC).

By using certified wood, garnering high environmental credentials, and optimising our production process, Knauf Insulation delivers wood wool products that are natural and sustainable. The high environmental credentials of Heraklith products are confirmed by their certification with Blue Angel, a voluntary programme that stands as the world’s oldest eco-label for products and services.

Heraklith makes available to our customers the Environmental Product Declarations (EPDs) for our products in various applications, each of which are based on the Life Cycle Assessment (LCA) carried out across all our plants. This allows us to quantify the benefit of using wood as a raw material and the impact of the binder and to accurately assess the environmental impact of product.

Knauf Insulation is committed to make available, upon request, environmental impact information related to products it places on the market. The format can either be a standard verified EPD or a simpler Environmental Fact Sheet (EFS) which is based on a verified EPD.

Life Cycle Assessment (LCA)
LCA InfographicThe Life Cycle Assessment (LCA) of any product is based on its environmental impact both inside and outside the production environment “from cradle to grave.” For our wood wool insulation boards, it includes the impacts of raw material extraction to produce the boards (including upstream processes, auxiliary processes, transportation, and energy use), manufacturing, transportation to the construction site, and end-of-life scenarios.

The full LCA results are reported in an Environmental Product Declaration (EPD). The results reported in any Heraklith EPD related to the LCA of wood wool insulation produced by Knauf Insulation covers all production sites and is based on using the wood wool boards in applications such as underground parking garages, basement ceilings, and pitched roofs.

Apart from providing environmental information on our products, Knauf Insulation is committed to sustainability. Our view and our policies are publicly available on the corporate website, and we produce an annual report in which we outline our achievements and our performance relative to the targets we have set to ourselves.

REACH documents
REACH Regulation (registration, evaluation, authorization and restriction of chemicals) places responsibility on industry to manage the risks from chemicals and to provide safety information on the substances. Manufacturers and importers are required to gather information on the properties of their chemical substances, which will allow their safe handling, and to register the information in a central database.
KI products strictly comply with REACH regulation. This compliance provide additional points through the building rating schemes like for example the new LEED version 4. Below you can find our LEED compliance document.
