Cellulose wadding as an alternative to mineral wool

We know well isolate the house remains the most financially accessible and faster in terms of return on investment to reduce energy consumption and reduce bills.

A report by the University of Colorado on 2 identical buildings, the first insulated with wool, cellulose, in second place with glass wool, gives evidence of superior thermal cellulose. It saves 26.4% energy compared to glass wool. House insulated with cellulose wadding is warmer than 4 ° after a period of 9am without heating.

It has also been shown in Germany during the summer of 2003 a house insulated wool cellulose had an ambient temperature below 6 ° to the identical house insulated with rock wool.

The time it takes to transmit a temperature from one side to another of its thickness, which makes cellulose wadding insulation exceptional. Specifically, the coolness of the night came at midday and vice versa (It is 80 cm mineral wool cons 20 cm cellulose for the same effect).

Insulation affordable and environmentally
Compared with other insulation used in ecological construction, only the cellulose wadding is economically competitive.

Indeed, the raw material (newsprint from unsold) is abundant and inexpensive. Its thermal and acoustic capabilities, its air permeability and moisture behaviour allow it to compete with insulating plants like flax, hemp and wood fiber and cost much more interesting.
Produce wool cellulose also allows the recovery of waste paper by recycling newspapers.
Finally, the manufacture of wool cellulose demands relatively little energy: 6 kWh / m³ (150 kWh/m3 cons for glass wool and 1000 kWh/m3 for polyurethanes). All these advantages make wool cellulose insulation used in the most eco-construction, whether for houses, timber and conventional homes.
