GUTEX then...
How it all began
GUTEX's beginning goes back to 1902, when the company
was originally established in the southern Black Forest to
provide surrounding communities with environment-friendly
hydroelectricpower.In1922,thecompanybeganmanufacturing
pulp for paper and corrugated board, using the water from a
river to drive its stone mills for the difibration of the wood.
The Henselmann family manufactured Europe's first insulation
boards in 1932 – at first, under the name Fahrnit, and later
renamedGUTEX.In1949,followingthewar,thecompanybuilt
amodernmanufacturingfacility.Thesingle-stagedryerusedback
then was fired for many years with coal before changing over
latertoheatingoil.In1991,GUTEXinstalledanenvironmentfriendlynaturalgasfiredstate-of-the-artsix-stagehotairdryer
withheatrecoverysystem.
Since 1995, GUTEX's quality and environmental protection
managementsystem,certifiedaccordingtoDINENISO9001,
ISO14001andEMASII(EUEcoAuditOrdinance),guarantees
the environmental compatibility and consistent high quality its
maxim"NATURALLYMADEFROMWOOD"promises.

...GUTEX today
And where it led
For more than 80 years, the Black Forest family-owned and
operated company GUTEX Holzfaserplattenwerk GmbH +
Co KG has produced insulating board from wood at its plant
inWaldshut-Tiengen, Germany. Now in its fourth generation,
the company, headquartered in Waldshut-Tiengen Germany,
employs 130 people and manufactures 11.5 million square
metres of wood fibreboard insulation annually.Today, GUTEX
is a leading manufacturer of innovative multifunctional woodfibrebasedecologicalinsulationsystemsforbothnewandold
buildings.
With its new dry process, GUTEX has broken new
ground, establishing new standards in environment-friendly
manufacturingandproductquality.
The leading producer of insulation board manufactured
from woodfibre in Germany, GUTEX is still manufacturing in
Waldshut-Tiengen, where it began 80 years ago. Sustainability,
that is, the careful handling of our available natural resources
is today a must. Rather than a current trend, sustainability for
GUTEXhasalwaysbeenanecessity.
To keep up with the increasing demand for its insulation
products, GUTEX installed in 2005 a second manufacturing
line that uses a highly innovative dry process.The new line is
exceptionally environment-friendly and capable of producing
homogeneoussingle-plyboardsinupto240mmthickness.
To maintain its competitive edge, GUTEX offers superior
product and service quality as well as superb stock availability.
All GUTEX insulation boards bear the CE and Ü marks of
conformity, indicating their compliance to the applicable,
valid standard or code. GUTEX’s external thermal insulation
composite system has the approval of the German building
materialsandphysicstestingagency.

resource, it has superb physical properties, such as fantastic
thermal and moisture regulating capabilities, which manifest

No other building material is so warm, so adaptable and so
alive.A multi-talent, wood is exceptionally versatile, making it
useable in unlimited constructional applications and variations,
including sustainable buildings.Thanks to wood's low thermal
conductivity and high volumetric heat capacity, warmth
remains indoors during the winter and outdoors in the
summer.Wood is naturally endowed with all the qualities you

Minimum environmental impact, ecological to
the core
The ecological credits for GUTEX's products begin where
they should, with the raw material. It comes solely from
wood that is harvested and grown using sustained forestry
management practices (PEFC and FSC). And GUTEX uses
exclusively untreated spruce and fir chips and shavings that
are by-products produced by other timber manufacturing
processes. Moreover, the sawmills from which GUTEX
obtains its chips and shavings are all located near its plant,
translating into less pollution and fuel consumption thanks to
reducedtransportdistances.Andcertainlynottobeforgotten
is the fact that GUTEX wood fibreboards are biodegradable
andcanberecycled,providedtheyhavenotbeentreatedwith
woodpreservatives.
But there is another very convincing ecological advantage
providedbyGUTEXwoodfibreboard.Byprocessingthewood
scrap into a useful product, its assimilated carbon dioxide is
kept from being released into the atmosphere.What could be
greener?

Fire Protection
Insulation in Summer
To protect living spaces against heat,
especially those directly under roofs, the
insulation material used must have enough thermal storage
capacity or volumetric heat capacity to ensure the flow of
warmth from the exterior to the interior area is adequately
dampened.Wood has a thermal storage capacity of 2100J/kg,
giving it the highest capacity of any construction material.
That’s why wood insulation boards provide significantly better
insulation against heat in summer than conventional insulation
materials.

What is the best way to insulate against summer heat?
Besides the usual constructional factors, like location and size
of the windows, air and wind tightness of the building and
ventilated construction, the choice of the right insulation
materialisdecisive.
The best insulation material
The ideal insulation material is one that provides effective
protectionagainstcoldinwinterandheatinsummer.GUTEX
wood fibreboards perform superbly in both applications. For
example,GUTEX Thermosafe-homogen®boardspossessathermal
conductivity coefficient of 0.037 (W/mK) and a specific heat
capacityof2100(J/kg*K).

Healthy Indoor Environment
GUTEX wood fibre insulation boards permit diffusion (μ value = 3) and regulate the
interiorrelativehumiditybyvirtueoftheirabilitytoabsorband

of insulation capacity.These two functions improve the living
environmentofindoorareassignificantly.
Water vapour diffusion
Diffusion is the migration of
individual, tiny particles (water
molecules) resulting from random
thermal agitation (Brownian
Motion). Everyone is familiar with
GORE-TEX and its benefits in
sportsclothingfabrics,particularly,
its breathability, which allows
perspiration to evaporate and
escape, leaving the individual with a dry, comfortable feeling.
A home or workplace is no different.Avoiding condensation
on windows, interior walls, etc. is essential to maintaining
a pleasant and healthy indoor climate. Construction materials
that permit diffusion and transport moisture offer distinct
advantages.GUTEX soft fibreboards feature excellent water
vapour permeability due to their very low water vapour
diffusionresistancefactor(μ)of3.
