External walls

For external walls and facades
External walls

Studies show that external walls are responsible for approximately 25% of the heat loss in a building. Consequently, the thermal insulation of external walls and façades can greatly improve the thermal performance of the building, resulting in reduced energy use and increased comfort for its occupants.

In addition to its insulating properties, external wall insulation must meet special requirements such as the ability to “breathe”, so that damaging moisture is not trapped against the external masonry, and the masonry is able to dry naturally if it becomes wet.

Heraklith wood wool insulation boards are well suited to satisfy such requirements. They can be applied as a breathable substrate board for lime render or plaster on an external wall for new construction. And they can be used in home renovation projects, as well, where the wood-wool insulation boards can be applied directly to existing plaster.

Heraklith wood wool insulation boards comprise an exceptional, all-in-one insulation solution for external building walls. Not only do they provide superior thermal and acoustic insulation performance, they are fire resistant and easy to install. They are also highly durable, including to be shock proof and can last for the lifetime of the building.

And due to the fact that they are derived from sustainable natural materials, they represent an eco-friendly and environmentally responsible approach to external wall insulation. 

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…

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.

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…

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…
