WERRO WOOL has the ability to absorb moisture and at the same time release it into the environment - which other insulation materials cannot. The absorption properties of WERRO WOOL affect the good ventilation of buildings, therefore it is not necessary to use an additional gas barrier as well as steam insulation. WERRO WOOL improves the indoor climate and prevents condensation. Building ventilation and a good indoor climate is particularly important in areas where the radon released is higher than the norm (radon - a gas produced independently by the earth's crust, which is toxic and dangerous to humans). It also maintains moist cellulose in dry seasonal structures, which reduces the construction of thermal bridges and extends the life of the building.

Werro Wool is hypoallergenic

Because cellulose is made from natural materials (newspapers, paper or processed wood fibers), it is an excellent insulation material for residential buildings, even for people with allergies. Isolation from cellulose fibers is particularly recommended for use in public buildings (such as schools, kindergartens, nursing homes, etc.). There is a perception that current boron compounds in ecosystem are dangerous to humans. In fact, however, scientific studies show that it is not harmful to health. Eco-wool brand "WERRO WOOL" are produced in a special technology where some boron compounds have been replaced with aluminum compounds. The material maintains its properties, e.g. fire and pest resistance.

WERRO WOOL - environmentally friendly material

90% eco-wool is made of waste paper, which ensures significant saving of resources in the Earth and the environment. Isolation from cellulose fibers is also suitable for recycling and reuse as insulation material - when it is necessary to demolish buildings. The production process is organized in accordance with international quality standards. It is ISO 9001: 2008 Management System certified (available for inspection here). "Werro Wool" packaging is also recyclable because it is made of paper.

Werro Wool fire resistance

"Werro Wool" thermal insulation materials are fire resistant. The fire resistance tests carried out gave the following results: D - s2, d0 (Euroclass scale). This means that the combustion of the material is long-term and low flame (20 mm high), the material is heat resistant and the combustion process is slow and limited. This result was obtained by an independent laboratory and an experimental protocol can be found here. The material acquires fire resistance due to the addition of boron and aluminum salts, which constitute up to 15% of the product. The "Werro Wool" brand constantly conducts research on the fire resistance of its product. Many of the competing products in heat-insulating products with the highest fire resistance class have a low melting temperature of the material, which affects the rapid release of harmful substances. Eco-watts fire safety has been proven in numerous studies. Eco-wool and mineral wool fire safety test video below.

Pest resistance

Cellulose fiber insulation contains boron compounds to deter rodents and pests. Boron compounds provide good protection against various forms of mold, fungus. This is especially important during various accidents when leaking into water. When wet, it dries and maintains its insulating and protective properties.

Sound insulation

"Werro Wool" thanks to its perfect construction isolates the sound. Significantly increases the sound insulation of external and internal walls. The use of cellulose insulation "Werro Wool" makes steam insulation superfluous, which saves material and time, which is important at the planning stage.

Manufacturer's recommendations

Why do manufacturers require compliance by density and thickness depending on the place of use?
There are tendencies to ignore the manufacturer's recommendations as to the applications of the material in - more air and less material - which contributes to a lower cost in. The result of this apparent saving is quickly visible - the thickness of the wool quickly decreases (settles) thereby reducing heat resistance, which gives unwanted result. As producers, we provide all necessary information about the properties and uses of eco-coffee.
