7 Myths virtually sheep’southward wool insulation
Are you planning to build a house, an extension onto your space or a renovation? If salubrious indoor air and natural materials are important to y’all, you should consider sheep wool insulation.
This article is our way of helping you visualise a new concept: sheep’s wool as insulation cloth. We clear up whatsoever concerns or prejudices and share with you the experience from our development as well as from numerous construction projects.
Sheep’s wool insulation smells or stinks
If you accept a sheepskin at dwelling, you may be familiar with the typical smell of fur. Where does the smell come from?
In the example of sheepskin, the aroma tin can be caused by tanning. The master reason for the aroma emanating from the sheepskin is the
lanolin, the wool fat
The smell is created because the wax in the sheep’southward fur is exposed to the influence of sun and conditions and thus oxidises.
Lanolin wool fat
Sheep produce the wool fatty lanolin by means of their skin sebaceous glands. This fat – also chosen lanolin – acts as a
natural protective film
around the wool fibre and thus protects the sheep against cold and wetness.
Then, lanolin is not a bad thing. On the contrary, the wax is fifty-fifty used in corrective products because it has many positive properties.
Are you planning to insulate your house and are now afraid that an off-putting aroma volition spread from room to room? Nosotros can take away this worry, as a thorough cleaning during the production process volition rapidly solve this trouble:
Commencement, the raw wool is rinsed in a gentle washing process using
This removes wool grease and cellulosic and organic
from the raw wool.
Afterwards, the cleaned wool is
rinsed with soda
to remove the soap residues.
The rinsing process removes any unpleasant odours from the wool. All that remains is a tiny amount of lanolin. We want to go along this considering it ensures that the elasticity and bounciness of the wool fibres are maintained. Even so, no scent emanates from the wool subsequently washing.
Sheep wool insulation moulds
Mould is a pocket-size fungus that can likewise settle in textile fibres every bit yellowish or blackness mould stains.
provides a good
convenance footing for mould stains
and allows the fungal spores to spread well.
When it comes to mould,
shows one of its superpowers: it can
absorb up to 33% of its own weight in moisture
and release it over again when dry.
of the protein
works through the interaction of the outer beat and the fibre trunk:
- The multi-layered
of the sheep’s wool fibre is hydrophobic, i.e.,
- However, this outer crush, also chosen the cuticle, allows
laissez passer through.
- The water vapour thus reaches the
inside of the wool fibre, the fibre body.
- In the
fibre trunk, the wool fibre can absorb almost 1/iii of its ain weight without the wool feeling moisture.
For all our insulation products, this ways that the wool does
despite loftier moisture absorption. It absorbs the moisture when it is higher and releases it over again to optimise the indoor climate.
Sheep’s wool is therefore also ideal for installation in challenging building situations, because the protein fibres of sheep’s wool practice not provide a breeding ground for mould.

Circumspection: Added support fibres or support grids change the moisture behaviour of the sheep’s wool insulation!
Be thorough when choosing a manufacturer, because unfortunately there are also blackness sheep in our industry. Only a sheep wool insulation manufacturer who uses 100% pure new sheep’due south wool,
without any additions of synthetic back up fibres or support grids
of harmful substances, such equally formaldehyde.
behaviour of the wet
with admixtures of other fibres, the production is no longer naturally degradable with synthetic admixtures and therefore landfill costs are consequential.
Sheep’s wool burns hands
Conventional insulation materials such as glass wool or rock wool fall into burn down protection class A1 – not-combustible. The synthetic, expanded polystyrene is found in class B. We are not at that place however with our environmentally friendly and good for you sheep’south wool.
Nevertheless, through constant technical evolution, we have managed to place our ISOLENA insulation materials in
fire protection class C and D
and to obtain the European Technical Approval (ETA). Our sheep’s wool has the following fire properties:
of virgin sheep’south wool is
– about twice that of wood (270°C).
- Sheep’s wool naturally has a loftier
which has a
is in the middle range (smoke development s2), in that location is no strong smoke development.
- In case of ignition, the insulation melts away from whatever heat source
(dripping behaviour d0).
Thus, sheep’s wool is a suitable insulation material for a wide range of building projects and has acceptable fire behaviour in case of fire. Our many
speak for themselves.
Sheep wool insulation rots
Sheep’due south wool has adapted to the most adverse conditions over thousands of years and has thus developed
far-reaching states of resistance.
In other words,
sheep’s wool “functions” permanently
within all kinds of conditions. When installing sheep’s wool insulation correctly, you don’t have to worry virtually the insulation rotting, mainly considering the
wool fibre binds wet.
However, one tin also notation that sheep’s wool tin be 100% recycled in an ecological bike. Your sheep wool insulation can therefore exist
negative environmental impacts.
Your sheep wool insulation can exist completely recycled without causing whatsoever negative environmental touch on.
Mice or insects nest in sheep’s wool
Mice, ants and other vermin
Mice, ants and other vermin
are no threat to sheep’s wool for several reasons. The wool is made of keratin and is
for these animals. Unlike cellulose or plant fibres, which consist of starch fibres, sheep’southward wool cannot be processed by these animals’ stomachs
In addition, the fibre organisation in our insulation materials is such that there is a
for these animals
to get caught in it, then they will tend to avoid the insulation material.
Moths and carpet beetles
When it comes to
moths and rug beetles, good sheep wool insulation must have a working wool protector to withstand these critters.
Nosotros are very proud to be the merely supplier to have co-developed an innovative
BIOZIDE FREE wool protection. Our IONIC PROTECT® wool protection is based on a plasma procedure too as being permanent and irreversible. The wool protection is
tested according to EAD and CUAP.
Sheep’due south wool insulation is out of my budget
If you make a direct price comparison betwixt dissimilar insulation materials, sheep’s wool insulation is more expensive than conventional or synthetic insulation.
Still, if one considers the entire life cycle of the insulation fabric and whatever potential side effects, the cost of sheep’s wool insulation is put into perspective:
- Thanks to the outstanding quality of naturally produced sheep’s wool, one’s investment would pay off after a very brusk time due to the
excellent insulation value.
- With other insulation materials, loftier disposal costs may too exist incurred during
conversion and renovation work, which are frequently not considered in the calculation – an particular that is omitted with sheep’due south wool insulation.
- He who buys inexpensive, buys expensive – An German maxim that is unfortunately continuously relevant to firm building. Time and again, builders discover our insulation textile as they retrace their steps: for example, when
is required immediately after
because the formaldehyde values rocket, and costly improvements must then be made.
A higher initial investment is an investment in the time to come and above all in your
and that of your family unit. In addition, depending on the (federal) country, there are numerous
to help home builders.
Sheep’due south wool insulation shrinks
The needling and felting of our sustainable sheep’due south wool gives our insulation materials
to be safe from shrinking, provided they are installed correctly.
needling, the cleaned and degreased wool fibres are shaped – we call this carding. The carded wool is so worked with felting needles, so that the
fibres of the wool interlock with each other
through the repeated piercing and thus a stable wool felt is created.
sheep’s wool insulation with continuous needling stands out in terms of stability and steadiness.
Due to the
industrial mass production of inexpensive, synthetic materials, sheep’s wool insulation is comparatively more expensive, only information technology scores loftier with many positive properties that the synthetic contest cannot match.
In addition, insulation made from sheep’s wool is piece of cake to
and tin be hands installed without safety measures such as protective goggles or dust masks!
If a cloth like sheep’s wool were reinvented today, information technology would hit the headlines as sensational, thanks to the many positive properties of this natural production.
