Environmental Product Declaration STEICO – wood fibre insulation
wood fibre insulation mats produced using the dry
process.
STEICO wood fibre insulation is highly versatile and
can be used for wall, roof and floor systems. It can be
used as an acoustic base insulation against impact
and airborne sound below parquet or laminate floors,
as an insulation element that can be directly plastered
for composite thermal insulation systems, and as
flexible cavity insulation.

2.4 Placing on the market / Application rules
Directive (EU) No. 305/2011 applies for placing the
product on the market in the EU/EFTA (except
Switzerland). STEICO wood fibre insulation materials
require a Declaration of Performance taking
consideration of the harmonised product standard
EN 13171:2012 thermal insulation materials for
buildings - Factory-made wood fibre (WF) products -
Specification (STEICOflex, STEICOtherm,
STEICOtherm internal, STEICOthermSD,
STEICOisorel, STEICOroof, STEICOprotect M,
STEICOprotect H, STEICOuniversal and
STEICOspecial)
and
EN 13986:2015, Wood-based panels for use in
construction - Characteristics, evaluation of conformity
and marking (STEICOisorel, STEICOunderfloor) and
CE marking.
The relevant national provisions apply for the use of
the products, the General building inspection approval
(abZ) No. Z-23.15-1452 of the German Institute for
Building Technology (DIBt), Berlin apply in Germany
for STEICO wood fibre insulation materials in acc. with
EN 13171.

2.6 Base materials / Ancillary materials
Apart from wood fibres, wood fibre insulation materials
consist of binding agents and other additives. The
proportions averaged from the various products for the
Environmental Product Declaration are:
wood, primarily coniferous wood: 82.8 %
water: 6.0 %
adhesives 1.2 %
bi-component fibres 1.3 %
recycled paper 6.3 %
flame retardants 2.4 %
miscellaneous 0.1 %
Polyurethane, phenolic resin, sodium silicate and
paraffin are used as adhesives and for hydrophobic
treatment. The bi-component fibres consist of
polyethylene and polypropylene. Aluminium sulphate is
used as a flame retardant. The apparent density of the
declared average wood fibre insulation material is
157.49 kg.
