Ecowools properties as
insulation material
Better Technologies to Build Better
Cellulose fibre insulation = Ecowool has been used in the world over 60 years. By now millions of houses
have been insulated with cellulose fibre.
As a result of continuing research work Ecowools a competitive consistency cornerstones are established:
Ecowool insulates effectively
thermal conductivity n = 0.040 W/mK
Because of the density of the material the air conductivity of Ecowool is small
air conductivity 80...120 x 10-6 m3/msPa
In any fire cases Ecowool neither burst into flames, nor smelt, nor sinter but smoulder slowly. This is
due to the used fire retarding agents - boron compounds. During the possible fire Ecowool's boron
compounds release their crystallization water and in this way moisten the insulating layer, cool down the
heat and retard the fire. Ecowool has an ability to protect the structures against fire
As a wood fibre -based insulation material Ecowool has excellent moisture properties. By using Ecowool
as insulation material wood-framed external walls can be built without plastic film vapour barrier
Boric acid is used as fire retarding agent. Borax is effective rot retardant. These boron compounds
prevent the growth of fungi. Even existing fungus die when they come into contact with Ecowool. Microorganisms or smaller rodents do not thrive in the insulation

WOOD FIBRE AS RAW MATERIAL
As a wood fibre-based insulation material Ecowool contains the good
thermal properties of wood
AIR
Ecowool utilizes the good thermal insulation ability of air. In Ecowool
there is 85 - 92 % unbound air. Even the fibres themselves contain air
and act as insulation
DENSITY
Ecowool's density is result of effective manufacturing process: in
process recycled paper is shredded mechanically down into extremely
fine wood fibres
Because of Ecowool's density, the air which is in the material stays
stagnant. So the material utilizes stagnant air's ability to insulate well
Ecowool's air conductivity is small due to the fine and tight consistency
METHOD OF INSTALLATION
Ecowool is blown or sprayed into the space to be insulated. In this way
Ecowool reaches all the most inaccessible nooks and crannies and
provides a seamless and tight insulation

Air conductivity
Better Technologies to Build Better
Ecowool's air conductivity is small. This
property is based on two typical features
of wood fibre:
The fine of wood fibre slows effectively
movements of air
Because of chances of relative air
humidity the Ecowool's upper layer
becomes tighter and the fibres of upper
layer stick together little by little
forming into the upper surface thin
paper like layer which prevents
effectively the penetration of air stream
into the inside layers of insulation

Fire properties
Better Technologies to Build Better
Ecowool's fire resistance properties are
based on boron compounds - boric acid
and borax. Due to properties of boric acid
and borax Ecowool neither burst into
flames nor smelt; only smoulders
slowly.
Fire retarding agents effect two ways:
1) they direct combustion reaction so that
during fire the amount of combustible
components is minimum, and the amount
of generated carbon is maximum
2) fire retardants have a moisturizing
effect. When they heat up they disengage
their crystallization water and prevent
the access of oxygen. In this way they
slow the fire and cool down the insulation
layer. Because of this Ecowool endures
extremely well the stresses of fire.
No toxic gases are evaporated from
Ecowool during the fire.

Moisture properties
Better Technologies to Build Better
As organic insulation material Ecowool's moisture behaviour varies from typical moisture behaviour of
other insulation materials.
MOISTURE BEHAVIOUR
Inorganic insulation materials
The fibres of inorganic insulation materials are incapable of binding and releasing moisture
air and water move between the fibres or along them
moisture does not bind into insulation. When the moisture condenses into water, it flows between the fibres down to
constructions and may cause rot and decays
the insulation material must be isolated against moisture
use of plastic film vapour barriers is necessary within inorganic insulation materials
ECOWOOL/organic insulation materials
Ecowool's raw material wood fibre is capable of binding moisture and releasing it without losing its thermal insulation
properties
Ecowool's moisture content follows the relative air humidity like wood
Because of this property - breathing - Ecowool insulated houses can be built without vapour barrier
Installation
Better Technologies to Build Better
Ecowool is installed into space to be insulated by blowing when the material reaches all the most
inaccessible nooks and crannies and provides a seamless insulation layer. As blown, the material
surrounds tightly electric pipes and other constructions which are difficult to insulate
insulation layer will be dense and without gaps
there are no leaking joints in lead-throughs and lattices
METHODS OF BLOWING
There are two methods of blowing
The spray on -method used in open wall
constructions gives undeniable advantage
for Ecowool's user. When the material is
moisturized with water, the lignin of wood
fibre will activate and it will function like a
glue. This means that Ecowool adheres
tightly in the constructions and forms a
dense insulation layer without any gaps.

waste pieces only the amount needed. This is a big advantage compared with board like insulation
materials. Blowing is a very quick method and guarantees a superior installation result.

Ecowool is made from recycled paper. Ecowool contains 80 % pure recycled newsprint and rest 20 %
non-volatile and safe fire and rot retarding agents.
As raw material the recycled paper is removed from general waste, thus reducing the overall burden.
Processing into Insulation is an ideal use for recycled paper.
Ecowool's manufacturing process does not harm the environment
Ecowool's manufacturing process is simple. It has two main phases:
1) pre-crushing where the recycled paper is pre-shredded and
2) refining where the pre-crushed paper is milled into a very fine fibrous form. In the second phase the fire
and rot retardants are added.
Manufacturing of Ecowool does not harm the environment with toxic emissions, nor does it use
non-renewable natural resources. The energy consumption of process is low.

ECOWOOL DOES NOT CONTAIN ANY VOLATILE, UNHEALTHY PHENOLIC ADHESIVES
Injurious effects of compact constructions can be avoided
Due to energy saving campaigns, tightness of constructions is improved and the amount of insulation
materials is increased. For example, the effectiveness of thermal insulation is improved by using plastic
film vapour barriers. By using the plastic film vapour barriers
is made sure that the air in the insulation stays stagnant
the harmful moisture of indoor air does not condense into the external walls of the building
These tight plastic vapour barrier constructions may:
deteriorate the quality of indoor air
Cause the use mechanical ventilation. The consequence of this may be unsatisfying indoor air quality
and damage to structures
The above mentioned inconveniences can be avoided by naturally breathing structures. This means constructions
without vapour barriers.
Healthy insulation material
Better Technologies to Build Better
Ecowool's raw material wood fibre is able to bind moisture and release it
without losing its thermal insulation properties
Ecowool's moisture content follows the relative air humidity like wood
Because of this property - breathing - Ecowool insulated houses can be built
without vapour barrier. In this way the quality of indoor air will be improved
and the injurious effects of impermeable constructions can be avoided
Ecowools advantages
for end user
Better Technologies to Build Better
Choice of Ecowool insulation means for the end user:
ECONOMICAL
LIVING
The time of cheap energy is over. Ecowool's good thermal insulation ability
means to the end user energy savings, savings in heating/cooling costs
Ecowool reduces repairing costs because it protects the building effectively
against harmful effects of cold/hot and moisture
Also the savings during the building time are remarkable. By using Ecowool there
will be no waste, only the amount needed
HEALTHY LIVING
Ecowool is totally healthy safe: It is neither harmful during manufacturing nor
during installation nor during use. It is made from natural materials and due to
its properties it it possible to avoid the injurious effects of compact constructions
and the use of unhealthy chemicals
