Cellulose insulation is a modern and sustainable insulation material made from recycled newspaper. It combines excellent thermal insulation properties with an environmentally friendly production process. But how exactly is this innovative insulation material produced, and which ingredients ensure it is both efficient and safe? Let’s dive in.

The production of cellulose insulation

The production of cellulose insulation is an environmentally friendly process that transforms waste materials into high-quality insulation. Here are the individual steps in detail:

Collection and cleaning of newspaper

Recycled newspaper forms the basis for cellulose insulation. It is sourced from recycling centers and collection points. The paper is then carefully cleaned to remove contaminants such as plastic, metal, or adhesive residue.

Shredding into cellulose fibers

The cleaned newspaper is shredded in small steps into fine cellulose fibers. This process creates the soft, fluffy structure that characterizes the insulation material.

Treatment with fire retardants

The cellulose fibers are treated with mineral fire retardants such as borates. These additives make the insulation fire-resistant while also protecting it against mold and pest infestation.

Treatment and flocculation

After treatment, the fibers are blended, flaked, and dried. This step ensures the homogeneous consistency and optimal density of the insulation material.

Packaging and transport

The finished cellulose insulation is filled into bags or bulk packages, sealed, and prepared for transport. From there, it goes directly to construction sites or warehouses.

The ingredients of cellulose insulation

Cellulose insulation is not only efficient but also environmentally and health-friendly. Its main components are:

Recycled newspaper

The core component of cellulose insulation is recycled newspaper. This makes the insulation a sustainable solution because it effectively reuses paper waste.

Mineral fire retardants

Borates, which are used as fire retardants, are mineral in nature. They prevent flammability and protect against moisture and pests.

Environmentally friendly adhesives

To ensure the stability of the insulation material, non-toxic adhesives are used to hold the fibers together without harming the environment.

Additives for pest control

Additives such as borates not only act as fire protection, but also protect the insulation material from mold and pest infestation, which increases its longevity.

The advantages of cellulose insulation

Sustainable production

Production requires less energy than conventional insulation materials such as glass or rock wool. Furthermore, paper waste is effectively recycled.

Energy efficiency

Cellulose insulation offers excellent thermal insulation values. It retains heat in the building in winter and ensures a comfortable indoor climate in summer.

Environmental friendliness

Because cellulose insulation is made from recycled materials and contains no harmful chemicals, it protects the environment and promotes sustainable construction.

Soundproofing

Cellulose insulation not only absorbs heat but also sound, making it ideal for residential and commercial buildings.

Funding opportunities in Belgium and Luxembourg

In Belgium and Luxembourg, there are numerous funding programs that support the use of sustainable insulation materials. These include subsidies for energy-efficient renovations or new construction. You can find more information in our FAQs or by contacting us via our contact page .
