STEICO_ENVIRONMENTAL PRODUCT DECLARATION

5
Environmental Product Declaration STEICO – wood fibre insulation
potential for water, air or soil according to the current
state of knowledge (Test report by the Institut für
Baubiologie (Institute for Building Biology), Rosenheim,
D) (see verification in Chapter 7).
Health: When STEICO wood fibre insulation materials
are installed correctly, no health risks or impairments
are to be expected. It is possible that small quantities
of product substances may escape. Moreover, no
health-relevant emissions were detected (Test report
by the Institut für Baubiologie (Institute for Building
Biology), Rosenheim, D) (see verification in Chapter
7).
To guarantee overfulfilment of the statutory limit values
for emissions, radioactivity, VOCs etc., STEICO wood
fibre insulation materials are externally tested for these
(Test report by the Institut für Baubiologie (Institute for
Building Biology), Rosenheim, D) (see verification in
Chapter 7).
2.13 Reference service life
On account of the many different possible applications
for STEICO wood fibre insulation, no reference service
life is declared.
Strength in condition of use for STEICO wood fibre
insulation is defined through the application classes in
acc. with DIN EN 13171 and DIN EN 622-4. The
average service life is in the order of that of the
building.
Influences on ageing when the recognised rules of
technology are applied.

Water
STEICO wood fibre insulation materials have no
soluble ingredients that are hazardous to water. Wood
fibre insulation materials are not permanently resistant
to standing water. Depending on the damage
symptoms, damaged areas must be replaced, either
partially or extensively.
Mechanical destruction
The product is mechanically resistant (pressure, tensile
load) depending on the insulation material used. In the
event of damage, uneven soft breakage occurs.
2.15 Re-use phase
When dismantled without damage, STEICO wood fibre
insulation materials may be re-used for the same
application after the end of utilisation, or may be re-
used in the same application spectrum in an alternative
location. Insofar as the wood fibre insulation materials
are not contaminated, the raw material can easily be
materially recycled and recovered (e.g. re-admission to
the production process).
2.16 Disposal
Per kg of wood fibre insulation, STEICO wood fibre
insulation materials can be used as renewable energy
sources with a calorific value of approx. 19.3 MJ/kg (u
= 35%), e.g. for burning in waste incineration plants.
Process energy as well as electricity can be generated.

3. LCA: Calculation rules
3.1 Declared Unit
The declared unit is 1m³ wood fibre insulation material
with an average apparent density of 157.49 kg.
The calculation of the apparent density and of the
proportions of the product substances in the declared
unit was effected by means of the production volume-
weighted calculation of the average of the products
manufactured in the plant.

3.2 System boundary
The declaration type corresponds to an EPD "from
cradle to gate, with options". It includes the production
stage, i.e. from provision of the raw materials through
to the works gate of the door factory (cradle to gate,
Modules A1 to A3), and parts of the end-of-life stage
(Modules C2 to C4). It also contains an analysis of the
potentials and debits over and beyond the product's
entire life cycle (Module D).
The information module A1 comprises the provision of
all semi-finished goods that can be found in the
declared unit as material. Transportation of these
substances is considered in Module A2. Module A3
contains all work and expenditures of the manufacture
of the product and its packaging from the cradle to the
gate, except the aspects already considered in
modules A1 and A2. Module C2 describes the
transportation as far as the disposal or recycling point,
Module C3 the preparation work which makes thermal
recycling possible. Furthermore, the CO2 equivalents
of the carbon inherent in the wood in the product, as
well as the renewable and non-renewable primary
energy sources in the product (PERM and PENRM),
are booked as outflows in Module C3, in accordance
with EN 16485. The debits and potentials resulting
from the end-of-life thermal utilisation of the product
and its packaging are analysed in Module D.
3.3 Estimates and assumptions
As a general rule, all of the material and energy flows
for the processes required for production are
established on site. Nitrogen and carbon monoxide
emissions are also established site-specifically. All
other emissions were calculated on the basis of
published studies - as described in Rüter & Diederichs
2012.
