Cellulose insulation

iCell cellulose insulation is manufactured in Sweden all the way from raw material to finished product.

Cellulose is superb insulation

Cellulose insulation is a bio-based, vapor-permeable, and moisture-buffering material that creates a stable and comfortable indoor climate. Its high heat capacity provides both winter and summer comfort, while the material also dampens sound and consists largely of recycled paper. Insulation material made of cellulose has very good performance, mainly thanks to three valuable properties:

Airtightness

Cellulose insulation is a so-called high-density product. This means that the material is extremely dense and has a relatively high weight volume. This helps to prevent unwanted air currents (convection) in the insulation and also provides high heat capacity.

Heat capacity

Heat capacity refers to the amount of energy required to heat 1 kg by 1 degree C. If the value is high, the material has great inertia. The value for glass wool is 670 joules per kg, rock wool 860 joules per kg. The value for cellulose insulation is an excellent 1600 joules per kg (according to EN ISO 10456), which in practice makes cellulose significantly more effective as insulation.

Convection

Cellulose insulation is a dense insulation consisting of cellulose fibers that also naturally contain air. This helps to bind the effect in so-called forced convection. Natural convection starts at a temperature difference of 15°C for glass wool, 22°C for rock wool, and not at all for cellulose, even at the highest temperature differences that may be relevant for house insulation.

You save energy and money

iCell primarily uses uncirculated newspapers for production. Recycling one ton of newsprint is equivalent to:

trees

kWh of energy

m³ of waste

Liters of clean water

kg of toxic waste

Insulation with iCell saves energy

Heating a house is a high cost for homeowners, so you want your house to have as little heat loss as possible.

A well-insulated house saves energy, but it is important to do it right to avoid problems with mold. Because iCell cellulose insulation breathes, you get a good indoor climate while insulating effectively.

What is cellulose?

Cellulose is nature’s most common organic substance and is naturally found in the cell walls of plants. During photosynthesis, plants convert carbon dioxide and water into carbohydrate and oxygen – into cellulose. No less than 100 billion tons of cellulose are formed in this way each year.

Cellulose has many properties that make it good as insulation. It absorbs moisture, which counteracts moisture problems and also means that diffusion plastic is not needed when building. It absorbs sound very well, a property that is increasingly appreciated in modern construction. The cellulose insulation also does not emit any unpleasant odor.
